Microservices Architecture pt.1: Definition by Lykle Thijssen

There is a lot of talk going on about Microservices architecture these days. Since I presented about the subject at the NLOUG Tech Experience this year, I've been getting a lot of questions and comments about it, so I've decided to make a more structured breakdown through a series of blogs. To kick things off, I will explain what Microservices architecture is, which in itself is not that simple. Definition There is no generally accepted definition of Microservices architecture. However, there are some starting points and generally accepted properties that I consider to be valid enough to see as part of the definition. Let's just start with what Adrian Cockcroft, the architect who introduced the concept at Netflix, has to say about it: "Microservices are loosely coupled service oriented architecture with bounded contexts" This pretty much sums it up, but it lacks detail to get a proper understanding of Microservices architecture. So, we need to analyze this sentence and draw some conclusions from it. First of all, mr. Cockcroft is clearly seeing Microservices architecture as a form of SOA, instead of something completely different. Then he goes on to put some limitations on how this SOA should be done:   Loosely coupled With bounded contexts   Why are these aspects so important? First of all, to understand why loosely coupled is so important here, one needs to understand how much SOA applications are built. They mostly rely heavily on reusable business services, a canonical data model and a shared runtime. It's not exactly what I would call loosely coupled, since there are quite some dependencies and the impact of making changes to a service or the runtime configuration can be rather large.

Oracle Cloud Native – deploying scalable isolated functions in the cloud by Léon Smiers

When moving to the cloud, and specifically when moving towards cloud-native applications, different design patterns apply when compared to the more traditional (on-premises) applications. All these cloud-native design patterns and principles have one common denominator – showing emphasis on scalability and function isolation. Where traditional applications used to be developed as big monolith solutions housing a large set of functionalities, the more modern and cloud-native applications are a collection of isolated functions that together form the application. The benefit of the more isolated function design is that each function can be designed and developed in relative isolation from the other functions. The microservices paradigm supports this way of implementing systems by its prime design principles around both function isolation and scalability In a system based on isolated functions, each function must interact with the others to support the system overarching functionality. Usually. no orchestration functionality is available in this architecture. Instead of a system overarching process engine to enable end-to-end functionality, a more choreography approach is used, where the functions themselves are responsible for the execution of a process. Additionally, each isolated function can be scaled up or down by adding more instances of a specific function if required. The need for isolated functionality and the ability to scale isolated functionality is driven by and helps fuel the adoption of microservices. When developing microservices, you will have a rich set of options and almost every modern language provides solutions and functionality to develop microservices (polyglot approach). One of the most favored approaches at this moment is using Java with the support of Spring. Additionally, you see developers and enterprises moving to an approach where each microservice is deployed within a container for obvious reasons.

JDev 12.2.1.3: Creating a shared skin jar (Part 1) by Timo Hahn

In earlier versions of JDev, skins have been created either by pure code or by using the free Skin Editor. However, since JDev 12.2.1.x the skin editor has been integrated into JDeveloper itself. A couple of questions in the ODC JDeveloper space are about how to create a skin with JDev which can be deployed as a shared library to a WebLogic Server. I gave this a try and it turned out, that you can build an ADF library jar from a skin project but you can’t use images to this jar which you might want to use in the application. In this blog, I’ll show how to create a skin with resources like images and how to build a jar file from the skin together with the images and deploy it aa s shared jar to a WeblogicServer. Building a skin project The first part is to build a small skin project. The project we use to create a minimal skin, just to show that the skin is changing something. Then we add some images to the skin which we want to use in the application which uses the skin. Such images can e.g. used on an af:button component.

JDeveloper – Increase Productivity Using Shortcuts by Pedro Curto

Integrated Development Environments (IDEs) are useful tools to maximize productivity for developers. This article will present how to configure new shortcuts and some very important advanced shortcuts available by default in JDeveloper that can be very useful to speed up development process. Introduction and Configuring Shortcuts In order to maximize programmer productivity, one important aspect is the use of some shortcuts. We all know some basic shortcuts like “CTRL+X” (to cut) or “CTRL+C” (to copy) and we use it every day as they save a lot of time. So, essentially, the shortcuts help you work more effectively and speed up almost everything you do. In other hand, long lists of keyboard shortcuts can quickly become overwhelming if you’re just getting started. The key to learn and memorize the shortcuts is to practice every day with a smaller but growing set. In order to help you, I will explain how to see the list of shortcut keys in jDeveloper and, also, how to configure your own. Firstly, to see the list of shortcut keys available in your jDeveloper, you can select “Tools->Preferences…” that will open a window with the “Preferences” of your environment. In that window select “Shortcut Keys” in the left. A list with all the shortcuts available are presented. Read the complete article here.

Oracle ADF BC REST – Performance Review and Tuning by Andrejus Baranovskis

I thought to check how well ADF BC REST scales and how fast it performs. For that reason, I implemented sample ADF BC REST application and executed JMeter stress load test against it. You can access source code for application and JMeter script on my GitHub repository. Application is called Blog Visitor Counter app for a reason - I'm using same app to count blog visitors. This means each time you are accessing blog page - ADF BC REST service is triggered in the background and it logs counter value with timestamp (no personal data). Application structure is straightforward - ADF BC REST implementation: When REST service is accessed (GET request is executed) - it creates and commits new row in the background (this is why I like ADF BC REST - you have a lot of power and flexibility in the backend), before returning total logged rows count: Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

Microservice Approach for Web Development – Micro Frontends by Andrejus Baranovskis image

This post is based on my Oracle Code 2018 Warsaw talk. View presentation on slides share. Wondering what micro frontends term means? Check micro frontends description here. Simply speaking, micro frontend must implement business logic from top to bottom (database, middleware and UI) in isolated environment, it should be reusable and pluggable into main application UI shell. There must be no shared variables between micro frontends. Advantage - distributed teams can work on separate micro frontends, this improves large and modular system development. There is runtime advantage too - if one of the frontends stops working, main application should continue to work. I have implemented micro frontends architecture with Oracle JET. Source code is available on GitHub repository. There are three applications, two with micro frontends and one is the master UI shell. Both micro frontends are implemented as JET Composite Components. First is hosted on WebLogic, it calls ADF BC REST service in the backend. Second is hosted on Node.JS and returns static data. First micro frontend implements listener, it allows to handle actions from the outside.

Adding New Oracle JET UI Component to Visual Builder Cloud Service by: Shay Shmeltzer

Oracle Visual Builder Cloud Service is an extendable platform - you can add your own UI components to the list of around 70 UI components that already show up in the component palette of your visual editor. In this blog and video we show you two ways to add additional Oracle JET components to the editor. In the first part of the video we show how to add a "core" Oracle JET components, specifically the train component. In the second part of the video (starting at minute 9) we show you how to add an Oracle JET Composite Component. For the core component, the main thing to know is that you also need to add the component to the json file that describes your page. This way VBCS will know to load this component into your pages. (This is needed since VBCS is optimized to only load needed resources - leveraging require.js for smart resource management).

5 main building blocks of the new Visual Builder Cloud Service by Herman Mensinga

Oracle introduced the new version of Visual Builder Cloud Service. This version is not just aimed at the Citizen Developer, in the end an experienced JavaScript can do nice things with it. In this blog I will have a look at 5 of the 6 main building blocks you build a VBCS applications with: REST service connections Flows and Pages Variables Action Chains UI Components Putting all of this in one blog is a lot, so this is a lengthy one. The final result can be found here. With VBCS you can create a lot using Drag and Drop! But in the end you have to be aware that it is all Javascipt, HTML5 and CSS you are creating. And it is all build on JET! Before we can start with these concepts, I create a New Application. Rest Service Connection I start with creating some endpoints for a publicly available REST API, https://docs.openaq.org/ An API with Air quality measurements This API contains several endpoints, the graph I am going to create uses the measurements API. As I am from the Netherlands, I use data from the Netherlands in this blog. First I create the Service Connection based on the Cities endpoint. 1. Create Service Connection by Service Endpoint.

A New Oracle Visual Builder Cloud Service – Visual and Coding Combined by: Shay Shmeltzer

We are happy to announce the availability of Oracle Visual Builder Cloud Service (VBCS) - Oracle's visual low-code development platform for JavaScript based applications with built-in autonomous capabilities. Over the past couple of years, the visual development approach of VBCS has made it a very attractive solution to citizen developers who leveraged the no-code required nature of the platform to build their custom applications. Many professional developers also expressed interest in the visual development experience they saw, but they were looking for additional capabilities. Specifically developers were demanding an option to have direct access to the code that the visual tools created so they can change it and enhance it with their own custom code to achieve richer behaviors. With the new VBCS version we are addressing these demands adding direct access to manipulate code, while keeping the low-code characteristics of VBCS. Visual and Code Based Development Combined Just like in previous versions, constructing the UI is done through a visual WYSIWYG layout editor. Existing VBCS users will notice that they now have access to a much richer set of UI components in the component palette. In fact they now have access to all of the components offered by Oracle JET (Oracle's open-source JavaScript Extension Toolkit). In addition you can add more components to the palette using the Web-components standard based Oracle JET composite components architecture (CCA). Read the complete article here.

What is Visual Builder and Why Is It Important for Your Business? By Shay Shmeltzer

For small-to-medium businesses (SMBs), developing engaging interfaces for your applications is a key step in the way to getting customers to adopt your solution. While new technologies are constantly providing new ways for growing companies to create better interfaces, developers sometimes struggle to keep up to speed with the latest emerging technology. In many SMBs with limited IT resources, developers can become a bottleneck for as they try to produce new applications at the speed of changing business needs. Add to this challenge the fact that it is no longer enough to provide just web interfaces, and that customers are also expecting great experience from mobile devices and your challenges just doubled. New Oracle Autonomous Cloud Platform Services The new Oracle Autonomous Visual Builder Cloud Service, released this month, aims to elevate these roadblocks by providing a visual development experience that accelerates and simplifies the creation of both mobile and web application – with zero installs thanks to a cloud based architecture.

Accessing Attribute Names and Values of a Data Object by Frank Nimphius

In this quick tip I show you how to use Apache FreeMarker expressions in Oracle Intelligent Bots to list the attribute names of a data object and to access the attribute value. Data Objects in Oracle Intelligent Bots Chatbots interact with remote services to complete a task and to display results. In Oracle Intelligent Bots, result data objects are queried by custom components and saved to context variables in the dialog flow. To save data from a custom component in a context variable you use the following call conversation.variable('name_of_variable', js_data_object); The data you save may be an array of objects or a single objects. The context variable you save the information to must be defined at dialog flow design time and must be of type "string". Accessing Attributes and Values of an Object For this sample, we will set the data object in the dialog flow of Oracle Intelligent Bots directly to make it easy for you to reproduce the solution. The solution actually works with Oracle Intelligent Bots version 18.1.5 and above. Note: if your data object is an array of objects then you simply add the index of the object in the array to the expressions shown below. e.g. data.value[0] accesses the first object in an array. Using Apache FreeMarker you can also determine the length of an array to iterate over all its contained objects. For the sample in this blog article, a single object will do though.

Building Complex Bot Responses with Ease Learn to love the common response component and render complex and composite responses by Frank Nimphius

The Oracle Intelligent Bots feature of Oracle Mobile Cloud Enterprise uses built-in components to render bot responses in a dialogue flow. Being component-based is an advantage Oracle Intelligent Bots has over its competitors, because it enables bot designers to easily build bot conversations with no code. The common response (CR) component is a relatively new component in Oracle Intelligent Bots that can render arbitrary complex and composite responses, thus making it even less likely that you’ll need to write code. About the Common Response Component With the rise of chatbots, messaging channels such as Facebook Messenger, Slack, and WeChat have become the equivalent of operating systems in client/server computing. Also like operating systems, whereas all messaging channels do the same things, they differ in the UI they can render, the functionality they support, and the message structure—the payload—they require. The CR component, like the Oracle Intelligent Bots list and text components, is built on top of a new channel-agnostic message model in Oracle Intelligent Bots that abstracts the channel specifics from component developers. For component developers, this new message model means that they can worry less and be more productive. For more concept and reference information on the CR component, refer to the documentation. About the Hands-On Instructions Following the hands-on instructions in this article, you will learn how to use the CR component to build a visually rich select list. To follow the hands-on instructions, you need access to Oracle Mobile Cloud Enterprise, which is available as a free trial. The starter bot for this article simulates a pizza ordering service. Users can order pizzas by typing, “I like to order a pizza” or “I like to order a pizza supreme.” In the latter case, because the type of pizza is included in the user sentence already, no pizza menu from which the user can select a pizza type is displayed. Similarly, a user may type, “can I see the menu?” for the bot to display a list of pizzas the user can order.

Enhance Vagrant provisioning: install java and database by Martien van den Akker

  In my previous blog posts (here and here), I wrote about how to create a base box and a create and start a virtual machine out of it. I started with provisioning, to have the vagrant user adapt the kernel settings, add a install user/owner and create a filesystem on an added disk. Now let's make the provisioning a bit more interesting and install actual software in it. Prepare new Vagrant project For this article I copied the project created from the previous blog. I called it ol75_db12c, since the goal is database 12c. But we'll also add java. Now edit the Vagrantfile, since we want a new VM with another name: So adapt the VM_NAME variable to something like "OL75U5_DB12c". You see how convenient it is to have those properties set as a global variable? You could already try to do vagrant up to try it out. Remember, you can just do vagrant destroy to recreate it. Also remove (or don't copy) the .vagrant subfolder, otherwise Vagrant would probably assume the box is already provisioned.  If that is the case, then either do a vagrant destroy to destroy the VM altogether, or vagrant provision to just re-provision the box. Java In the copied project, lets start with Java. There are several possibilities to install java, you could download the RPM from OTN. But one of the recommended practice I found in installing Java on a server is to put it in a path that hasn't got the java version (especially  the update) in it. When using it to install Weblogic, for instance, this path ends up in several places in scripts. Although it's a handfull, it's more than once. Upgrading java is then just bringing down the servers/services using it, backup the version and unzip/untar the new version in the same folder. And there you have it: I like a java distribution that comes in an archive. In Oracle Support you can find it by searching for the document All Java SE Downloads on MOS (Doc ID 1439822.1). There you find the current versions of the Java SE pacakges. For this article I used the public version JDK 8 Update 172, that you can download as patch 27412872: Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

It’s Better with Two Connect database and application services for a quick start to app development by Dan McGhan

Two of my favorite Oracle Cloud services are Oracle Database Exadata Express Cloud Service (Exadata Express) and Oracle Application Container Cloud. Exadata Express is a fully managed Oracle Database service at an entry-level price point for small-to-medium-sized data, and Oracle Application Container Cloud is a lightweight infrastructure that provides an easy way to deploy apps in Docker containers. In this article, I’ll demonstrate how to connect these two at the most basic level. What do I mean by “the most basic level”? The demo app will be minimalistic. Typically, I might use Oracle Developer Cloud Service to create a Git repository with an automated build process—but not here. This article will focus only on what’s needed to get Exadata Express and Oracle Application Container Cloud connected. At a high-level, the steps are Create a test app Add Exadata Express client credentials Deploy the app to Oracle Application Container Cloud Add some environment variables to get everything working Create a Test App The rest of this article assumes that you have an Oracle Cloud account with access to both Exadata Express and Oracle Application Container Cloud. (If you don’t already have an Oracle Cloud account, you can sign up for a free cloud trial. To connect and use Exadata Express and Oracle Application Container Cloud, start by creating a new directory named connection-test-app on your local machine. Now create two files in that directory.

CloudEvents Support and Serverless Framework Integration for Fn Project by Shaun Smith

The Fn team is committed to open standards and to integrating and interoperating with other open source projects. And with the Cloud Native Computing Foundation’s KubeCon EU 2018 taking place this week in Copenhagen we’d like to announce two new exciting developments: support for the upcoming CloudEvents specification and integration with the Serverless Framework. The CloudEvents specification is being developed by the CNCF Serverless working group to define a common event format that will make it easier to build cross-cloud/multi-vendor applications. With Fn’s CloudEvent support it’ll be easier to integrate Fn into your preferred platform ecosystem. CloudEvents is early, having just reached its 0.1 milestone, and Fn is adding support for this initial draft spec and will continue to track it and incorporate changes as it progresses onto a 1.0 release.

Microservices are not simple by Phil Wilkins

It’s a bit controversial to say ‘Microservices are not simple’ given much is said about using Microservices to simplify and accelerate software delivery. So, how can this statement be made? It is a point actually stated in Chris Richardson’s excellent new book Microservice Patterns (avalable here and here), indirectly in Eric Evan’s Domain Driven Design (here). Martin Fowler in one his blogs says that they come at a premium (here). So, I’m not the first to say this, and wont be the last. But the assertion that Microservices done right are simpler, and allow rapid delivery and evolution of solutions – a bit of a contradiction. As they say a picture is worth a thousand words, so take a look at this … To make a change with the monolith and understand what the impact of the change is you can it needs to have far greater appreciation of how the entire solution works (area highlighted in gray). It changes are implemented without the full understanding and adherence of the design strategies, patterns etc, or more commonly changes rushed in to address some urgent need (business deadline, bug and so on) the design is eroded and it the effort to understand the change impact accelerates. Net result, the monolith becomes difficult and unwieldy despite the best intentions. Microservices are inherently more complex because they need need to accommodate the possibility of being distributed they share less, therefore need a bit more foundation.  So now not only do you need to understand the programming language, and a simple app container such as Tomcat but also Docker and something like Kubernetes or Istio. But, and this important thing is that the isolation between the different services is more robust – no longer can you just add another import, add another method overload on class. It takes more effort and it is easier to govern the points of exposure. As a result, the risk of design degradation is reduced – but not removed.

Teaching How to Get started with Kubernetes deploying a Hello World App by Carlos Rodriguez Iturria

In a previous blog, I explained how to provision a new Kubernetes environment locally on physical or virtual machines, as well as remotely in the Oracle Public Cloud. In this workshop, I am going to show how to get started by deploying and running a Hello World NodeJS application into it. There are a few moving parts involved in this exercise: · Using an Ubuntu Vagrant box, I’ll ask you to git clone a “Hello World NodeJS App”. It will come with its Dockerfile to be easily imaged/containerised. · Then, you will Docker build your app and push the image into Docker Hub. · Finally, I’ll ask you to go into your Kubernetes cluster, git clone a repo with a sample Pod definition and run it on your Kubernetes cluster.

Oracle Adds New Support for Open Serverless Standards to Fn Project and Key Kubernetes Features to Oracle Container Engine by Bob Quillin

  Open serverless project Fn adds support for broader serverless standardization with CNCF CloudEvents, serverless framework support, and OpenCensus for tracing and metrics. Oracle Container Engine for Kubernetes tackles toughest real-world governance, scale, and management challenges facing K8s users today Today at Kubecon + CloudNativeCon Europe 2018, Oracle announced new support for several open serverless standards on its open Fn Project and a set of critical new Oracle Container Engine for Kubernetes features addressing key real-world Kubernetes issues including governance, security, networking, storage, scale, and manageability. Both the serverless and Kubernetes communities are at an important crossroads in their evolution, and to further its commitment to open serverless standards, Oracle announced that the Fn Project now supports standards-based projects CloudEvents and the Serverless Framework. Both projects are intended to create interoperable and community-driven alternatives to today’s proprietary serverless options. Solving Real World Kubernetes Challenges The New Stack, in partnership with the Cloud Native Computing Foundation (CNCF) recently published a report analyzing top challenges facing Kubernetes users today. The report found that infrastructure-related issues – specifically security, storage, and networking – had risen to the top, impacting larger companies the most.

Introducing Play with Kubernetes by Mano Marks

We introduced our new Build Engine in Oracle Developer Cloud in our April release. This new build engine now comes with the capability to define build pipelines visually. Read more about it in my previous blog. In this blog we will delve deeper into some of the functionalities of Build Pipeline feature of the new CI Engine in Oracle Developer Cloud. Auto Start Auto Start is an option given to the user while creating a build pipeline on Oracle Developer Cloud Service. The below screenshot shows the dialog to create a new Pipeline, where you have a checkbox which needs to be checked to ensure the pipeline execution auto starts when one of the build job in the pipeline is executed externally, then that would trigger the execution of rest of the build jobs in the pipeline. The below screen shot shows the pipeline for NodeJS application created on Oracle Developer Cloud Pipelines. The build jobs used in the pipeline are build-microservice, test-microservices and loadtest-microservice. And in parallel to the microservice build sequence we have, WiremockInstall and WiremockConfigure. Scenarios When Auto Start is enabled for the Pipeline: Scenario 1: If we run build-microservice build job externally, then it will lead to the execution of the test-microservice and loadtest-microservice build jobs in that order subsequently. But note this does not trigger the execution of WiremockInstall or WiremockConfigure build jobs as they are part of a separate sequence. Please refer the screen shot below, which shows only the build jobs executed in green.

Running Istio on Oracle Kubernetes Engine–the managed Kubernetes Cloud Service by Lucas Jellema

In a recent post, I introduced the managed Oracle Cloud Service for Kubernetes, the Oracle Kubernetes Engine (OKE). A logical next step when working with Kubernetes in somewhat challenging situations, for example with microservice style architectures and deployments, is the use of Istio – to configure, monitor and manage the so called service mesh. Istio – https://istio.io – is brand new – not even Beta yet, although a first production release is foreseen for Q3 2018. It offers very attractive features, including: intelligent routing of requests, including load balancing, A/B testing, content/condition based routing, blue/green release, canary release resilicience – for example through circuit breaking and throttling policy enforcement and access control telemetry, monitoring, reporting In this article, I will describe how I got started with Istio on the OKE cluster that I provisioned in the previous article. Note: there is really nothing very special about OKE for Istio: it is just another Kubernetes cluster, and Istio will do its thing. More interesting perhaps is the fact that I work on a Windows laptop and use a Vagrant/VirtualBox powered Ubuntu VM to do some of the OKE interaction, especially when commands and scripts are Linux only. The steps I will describe: install Istio client in the Linux VM deploy Istio to the OKE Kubernetes Cluster deploy the Bookinfo sample application with Sidecar Injection (the Envoy Sidecar is the proxy that is added to every Pod to handle all traffic into and out of the Pod; this is the magic that makes Istio work) try out some typical Istio things – like traffic management and monitoring The conclusion is that leveraging Istio on OKE is quite straightforward. Install Istio Client in Linux VM The first step with Istio, prior to deploying Istio to the K8S cluster, is the installation on your client machine of the istoctl client application and associated sources, including the Kubernetes yaml files required for the actual deployment. Note: I tried deployment of Istio using a Helm chart, but that did not work and it seems that Istio 0.7.x is not suitable for Helm (release 0.8 is supposed to be ready for Helm).

First steps with Oracle Kubernetes Engine–the managed Kubernetes Cloud Service by Lucas Jellema

Oracle  launched (May 2018) its Managed Kubernetes Cloud Service (OKE – Oracle Kubernetes Engine) – see for example this announcement. Yesterday I got my self a new free cloud trial on the Oracle Public Cloud (https://cloud.oracle.com/tryit). Subsequently, I created a Kubernetes cluster and deployed my first pod on that cluster. In this article, I will describe the steps that I went through: create Oracle Cloud Trial account configure OCI (Oracle Cloud Infrastructure) tenancy create service policy create OCI user create virtual network create security lists create compute instance configure Kubernetes Cluster & Node Pool; have the cluster deployed install and configure OCI CLI tool generate kubeconfig file connect to Kubernetes cluster using Kubectl – inspect and roll out a Pod The resources section at the end of this article references all relevant documentation. Configure OCI (Oracle Cloud Infrastructure) tenancy Within your tenancy, a suitably pre-configured compartment must already exist in each region in which you want to create and deploy clusters. The compartment must contain the necessary network resources already configured (VCN, subnets, internet gateway, route table, security lists). For example, to create a highly available cluster spanning three availability domains, the VCN must include three subnets in different availability domains for node pools, and two further subnets for load balancers.

Garbage First in JDeveloper by Martien van den Akker

At my current customer we work with VDI's: Virtual Desktop Images, that at several times a day very, very slow. Even so slow that it more or less stalls for a minute or two. JDeveloper is not known as a Ferrari under the IDE's. One of the causes is that by default heap settings is very poor: 128M-800M. Especially when you use it in  SOA or BPM Quickstart then at startup it will need to grow several times. But very soon working in it you'll get out of memory errors. Because of the VDI's I did several changes to try to improve performance. Main thing is set Xms and Xmx both at 2048M. I haven't found needing more up to this day. But I found using the Garbage First collector gives me a slightly better performance. To set it, together with the heap, add/change the following options in the ide.conf in ${JDEV_HOME}\jdeveloper\ide\bin\: Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

First steps with REST services on ADF Business Components by Jeroen Rijnboutt

Recently we had a challenge at a customer for which ADF REST resources on Business Components were the perfect solution. Our application is built in Oracle JET and of course we wanted nice REST services to communicate with. Because our data is stored in an Oracle database we needed an implementation to easily access the data from JET. We decided on using ADF and Business Components to achieve this. Of course there are alternative solutions available but because our application runs as a portal in Webcenter Portal, ADF was already in our technology stack. I would like to share some of my first experiences with this ADF feature. We will be using ADF 12.2.1.1. In this introduction we will create a simple application, the minimal required set of business components and a simple REST service. There are no prerequirements to start using the REST functionality in ADF. If you create a custom application you can choose to add the feature for REST Services but it is not necessary. Start with making a simple EO and VO: Before you can create any REST services, you need to define your first release version. The versions of REST resources are managed in the adf-config.xml. Go to this file, open the Release Versions tab and create version 1. The internal name is automatically configured based on your input: Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

ADF Performance Monitor – Major New Version 7.0

We are very happy to announce that a major new version 7.0 of the ADF Performance Monitor will be available from May 2018. There are many improvements and major new features. This blog describes one of the new features; on usage statistics and performance metrics of end-user click actions. A click action is the start trigger event of an HTTP request by the browser, by an action that a user takes within the UI. These are most often physical clicks of end-users on UI elements such as buttons, links, icons, charts, and tabs. But it can also be scrolling and selection events on tables, rendering of charts, polling events, auto-submits of input fields and much more. With monitoring by click action you get insight in the click actions that have the worst performance, that cause most errors, that are used most frequently, e.g. You can see in which layer (database, webservice, application server, network, browser) the total execution time has been spent. You can SLA monitor the business functions that are behind the click actions – from the perspective of the end-user. Worst Performing Click Actions Overview The ADF Performance Monitor has a new overview of the worst performing click actions – based on ADF click history, ordered by total (sum) processing time. The overview shows: · Component ID (ADF Faces component ID that started the request) · Component Type (ADF Faces component Java Class) · Display name (label/text if present on component) Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

Building Oracle Jet applications with Docker Hub by Eugene Fedorenko

In this post I am going to show a simple CI solution for an Oracle Jet application basing on Docker Hub Automated Builds feature. The solution is container native meaning that Docker Hub is going to automatically build a Docker image according to a Docker file. The image is going to be stored in Docker Hub registry. A Docker file is a set of instructions on how to build a Docker image and those instructions may contain any actions including building an Oracle Jet application. So, what we need to do is to create a proper Docker file and set up Docker Hub Automated Build. I am going to build an Oracle Jet application with OJet CLI, so I have created a Docker image having OJet CLI installed and serving as an actual builder. The image is built with the following Dockerfile: Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

A Simple Guide and Solution to Using Resource Bundles in Custom Components by Frank Nimphius

  A common requirement for bots is to support multiple languages. To address this requirement, Oracle Intelligent Bots provides the ability to configure translation services from Google and Microsoft to auto-translate user input messages and bot responses. If you don't want bot responses to be auto-translated then a second option is to use Resource Bundles instead. All the before mentioned options work great for building multi lingual bots, but require messages to be defined in the dialog flow, or saved in context variables. This excludes custom components that directly write user responses to the message channel using the bot SDK conversation.reply( … ) function. Without going into a longer discussion of when custom components should write message responses directly to a message channel and when they should save messages or data in a context variable, we simply accept the fact that there are use cases for custom components to be self-contained. This however then bears the question of how to implement translations for those responses. To translate bot responses sent directly from a custom component, you have two options Call a translation service from the custom component implementation code before sending a message. This option is suitable if the messages are not composed in the custom component but queried from a remote backend. Here auto-translation will help making the strings available in the bot user preferred language. Use message bundles to provide translated responses for the languages you want the bot to support. Message bundles can use placeholders in the translated strings for the custom component to insert data value at runtime. Message bundles in custom components are a viable option if the custom component queries data from a remote service to integrate in a bot response. The article (readme), and its sample, shows a simple solution to implement message bundle support in custom components. You can leverage the sample sources in your own custom component projects, and the readme in the sample tells you how.

Randomizing Responses from your Bot with Oracle Intelligent Bots by Grant Ronald

  One element to the success of your bot is the tone and voice your bots uses. Informal and “chatty” response may be a more engaging and better fit with your brand. In line with this approach, you would probably want to ensure your bot replies are not formulaic and predictable. In this article I demonstrate how you can easily randomize the responses from your bot. Randomizing the responses from your bot There are many different ways you can achieve this functionality but to keep the implementation as simple as possible I’ve done so by defining an array win the BotML and then using a simple pseudo random number generator (based on date/time) which picks one of your messages defined within the array. Furthermore, it’s quite simple to extend the array to include different message for different points in the conversation: welcome, goodbye, not understanding a response etc. The sample is simple and self-documenting. Import the bot and run it you will get three random messages for welcome, unresolved and goodbye. The only limitation with the code shown below is that since it takes the last digit of a time then it would expect 10 (0-9) possible messages within the message array. Read the complete article here.   For more information please see the Chatbot partner resource kit here.

Building Single Base-Language Chatbots with Oracle Intelligent Bots by: Frank Nimphius

Chatbot support for multiple languages is a worldwide requirement. Almost every country has the need for supporting foreign languages, be it to support immigrants, refugees, tourists, or even employees crossing borders on a daily basis for their jobs. According to the Linguistic Society of America1, as of 2009, 6,909 distinct languages were classified, a number that since then has been grown. Although no bot needs to support all languages, you can tell that for developers building multi-language bots, understanding natural language in multiple languages is a challenge, especially if the developer does not speak all of the languages he or she needs to implement support for. This article explores Oracle's approach to multi language support in chatbots. It explains the tooling and practices for you to use and follow to build bots that understand and "speak" foreign languages.

Displaying the Top 3 Runner-Up Intents in case of Unresolved Intent Resolution by: Frank Nimphius

In an earlier TechExchange sample from November 2017 titled "Strategy for Handling Unresolved Intent Resolutions So Users Remain Unstuck" we demonstrated a technique to display a list of intents that got resolved with more than 0% confidence in cases where intent resolution did not succeed passing the confidence threshold set on the System.Intent component. With the current version of Oracle Intelligent Bots there exists another option to handle the very same use case. In addition, it turned out that customer usually only want to display a specific set of "runner-up" intents as options in a list. This article is a revised version of the previous publication showcasing an implementation that displays the top-3 intents for an otherwise unresolved intent resolution. If there are no 3 intents to display then the solution shows as many as possible. And if there is no intent that gets resolved to above 0% then a single help item is shown for the user to find the help she may need. The solution uses the Common Response Component (CR component) for displaying the list along with Apache FreeMarker expressions to conditionally render list items and to sort the list of intents so the top three really have the highest confidence scores. And there is more for you to learn. Intent names usually don't make good names to display in a list of values. This sample shows you how the intent names can be used as a key in a resource bundle that allows you to display user-friendly list option labels and to internationalize the solution. The figure below shows the solution in the Oracle Intelligent Bots tester. As you will learn by reading the full article and by trying the sample bot, the list shows two resolved intents plus a help option that is always shown (but that can be changed to show conditionally as well).

GraalVM: Run Programs Faster Anywhere by Thomas Wuerthinger and the GraalVM Team

Current production virtual machines (VMs) provide high performance execution of programs only for a specific language or a very small set of languages. Compilation, memory management, and tooling are maintained separately for different languages, violating the ‘don’t repeat yourself’ (DRY) principle. This leads not only to a larger burden for the VM implementers, but also for developers due to inconsistent performance characteristics, tooling, and configuration. Furthermore, communication between programs written in different languages requires costly serialization and deserialization logic. Finally, high performance VMs are heavyweight processes with high memory footprint and difficult to embed. Several years ago, to address these shortcomings, Oracle Labs started a new research project for exploring a novel architecture for virtual machines. Our vision was to create a single VM that would provide high performance for all programming languages, therefore facilitating communication between programs. This architecture would support unified language-agnostic tooling for better maintainability and its embeddability would make the VM ubiquitous across the stack. To meet this goal, we have invented a new approach for building such a VM. After years of extensive research and development, we are now ready to present the first production-ready release. Introducing GraalVM Today, we are pleased to announce the 1.0 release of GraalVM, a universal virtual machine designed for a polyglot world.

First steps with Docker Checkpoint – to create and restore snapshots of running containers by Lucas Jellema

Docker Containers can be stopped and started again. Changes made to the file system in a running container will survive this deliberate stop and start cycle. Data in memory and running processes obviously do not. A container that crashes cannot just be restarted and will have a file system in an undetermined state if it can be restarted. When you start a container after it was stopped, it will go through its full startup routine. If heavy duty processes needs to be started – such as a database server process – this startup time can be substantial, as in many seconds or dozens of seconds. Linux has a mechanism called CRIU or Checkpoint/Restore In Userspace. Using this tool, you can freeze a running application (or part of it) and checkpoint it as a collection of files on disk. You can then use the files to restore the application and run it exactly as it was during the time of the freeze. See https://criu.org/Main_Page for details. Docker CE has (experimental) support for CRIU. This means that using straightforward docker commands we can take a snapshot of a running container (docker checkpoint create <container name> <checkpointname>). At a later moment, we can start this snapshot as the same container (docker start –checkpoint <checkpointname> <container name> ) or as a different container. The container that is started from a checkpoint is in the same state – memory and processes – as the container was when the checkpoint was created. Additionally, the startup time of the container from the snapshot is very short (subsecond); for containers with fairly long startup times – this rapid startup can be a huge boon.

Oracle Adds New Support for Open Serverless Standards to Fn Project and Key Kubernetes Features to Oracle Container Engine by: Bob Quillin

  Open serverless project Fn adds support for broader serverless standardization with CNCF CloudEvents, serverless framework support, and OpenCensus for tracing and metrics. Oracle Container Engine for Kubernetes tackles toughest real-world governance, scale, and management challenges facing K8s users today Today at Kubecon + CloudNativeCon Europe 2018, Oracle announced new support for several open serverless standards on its open Fn Project and a set of critical new Oracle Container Engine for Kubernetes features addressing key real-world Kubernetes issues including governance, security, networking, storage, scale, and manageability. Both the serverless and Kubernetes communities are at an important crossroads in their evolution, and to further its commitment to open serverless standards, Oracle announced that the Fn Project now supports standards-based projects CloudEvents and the Serverless Framework. Both projects are intended to create interoperable and community-driven alternatives to today’s proprietary serverless options. Bringing Kubernetes to Maturity The New Stack, in partnership with the Cloud Native Computing Foundation (CNCF) recently published a report analyzing top challenges facing Kubernetes users today. The report found that infrastructure-related issues – specifically security, storage, and networking – had risen to the top, impacting larger companies the most.

Functions-as-a-Service – What SOA Should Have Been by Sherwood Zern

Introduction It wasn’t that many years ago that service-oriented architecture (SOA) was the hot, new, bleeding edge enterprise computing paradigm. Most organizations and vendors jumped on that bandwagon and everything became “service-oriented”. Organizations and vendors both made great claims about how SOA would revolutionize the way applications were built, the amount of reuse that would be achieved, and how application time to market would be greatly reduced. In addition, applications built with SOA technology were supposed to be easier to scale dynamically and those businesses that embraced SOA would see vast improvements in the relationships between IT and the business. Unfortunately, the promises of SOA did not quite pan out across the board. Obviously, some organizations were successful, but far too many did not realize the promised benefits. There are many reasons why some succeeded and some failed but based on many years of first-hand experience building SOA applications and helping numerous customers with SOA-related challenges, here are three common reasons I noted those less than successful SOA projects: 1. Service Granularity. Organizations had a difficult time in defining what would be a service. Eventually, everything that was developed was referred to as a service. In a SOA environment, a service has versioning rules, is put under governance, and is normally categorized as intra-departmental, interdepartmental, or enterprise. To say that all developed code is a service would be overkill and it would mean tremendous overhead from an organizational and administrative perspective. Therefore, deeming everything a service normally means that none of this is put in place and the term service has no real SOA meaning. 2. Distributed Systems complexity. Developers had to be capable of understanding the complexities of distributed systems and the technologies involved with implementing distributed systems, think of transactions and security. Therefore, instead of focusing on implementing business logic a lot of effort was exhausted in worrying about the underlying technologies. 3. Scalability. The majority of “services” developed were deployed within application servers. This author is not saying application servers are bad but if one or two of the services needed to be scaled up or down it meant scaling the application servers. The scaling of application servers could be expensive, and most application servers cannot scale dynamically. The discussion in recent years has shifted from SOA to Microservices to Serverless and Functions-as-a-Service (FaaS). It is this author’s opinion that these technologies are really the next phase of SOA, maybe even what SOA should have been in the first place. Microservices and FaaS deliver on many of the promises that SOA had originally marketed; dynamic scaling, focus on the business logic and not the underlying technologies, and bounding the context of the service.

ADF on Docker - Java Memory Limit Tuning for JVM by Andrejus Baranovskis

It might look like a challenge to run Java in Docker environment, by default Java is not aware of Docker memory limits. Check this article for example - Java inside docker: What you must know to not FAIL.  I was able to run WebLogic and ADF (Essential WebLogic Tuning to Run on Docker and Avoid OOM) on Docker previously without Java memory issues, using JAVA_OPTIONS=-XX:+UnlockCommercialFeatures -XX:+ResourceManagement -XX:+UseG1GC. However after Docker upgrade to latest version, these settings didn't help anymore. I did't want to hardcode memory setting with -Xmx. Java started to consume all available memory in Docker and eventually was killed. You can see this from chart below - memory is growing, killed and after restart growing again: To solve this behaviour, I have applied settings from Java Platform Group, Product Management Blog - Java SE support for Docker CPU and memory limits. I have replaced JAVA_OPTIONS=-XX:+UnlockCommercialFeatures -XX:+ResourceManagement -XX:+UseG1GC set previously with JAVA_OPTIONS=-XX:+UnlockExperimentalVMOptions -XX:+UseCGroupMemoryLimitForHeap -XX:+UseG1GC. JAVA_OPTIONS=-XX:+UnlockExperimentalVMOptions - XX:+UseCGroupMemoryLimitForHeap -XX:+UseG1GC did the job - JVM stays in Docker memory limits sharp: Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

Find In Cache By Key ADF BC API Method Usage by Andrejus Baranovskis

  What if you need to verify - if row with given key exists in fetched rowset? This could be useful while implementing validation logic. ADF BC API method findByKey - will trigger SQL call and fetch row from DB, if row with given key doesn't exist in fetched rowset. Luckily there is ADF BC API method called findInCacheByKey, this method only checks for row in fetched rowset, without going to DB - very convenient in certain situations, when you actually don't want to bring record from DB, if it wasn't fetched. Now if we call custom method, where findInCacheByKey is invoked twice - you will see different results. First call is using key from fetched rowset - this call will find a row. Second call is using key, which doesn't belong to the fetched rowset - row is not in cache and call will return zero rows: Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

REST Paging Support by Oracle Offline Persistence in JET by Andrejus Baranovskis

Oracle Offline Persistence query handler - Oracle Rest Query Handler supports pagination for Oracle ADF BC REST service out of the box. Check my previous post to see how querying works through offline persistence toolkit for ADF BC REST service - Shredding and Querying with Oracle Offline Persistence in JET. Pagination is a must for large REST resources, its great that Oracle offline persistence toolkit supports it. Let's see it in action. I navigate through the data with left/right arrows, this triggers REST call with pagination parameters - limit and offset. These are standard parameters supported by ADF BC REST. Requests are executed online: All pages of data are cached by offline toolkit, if while offline we try to access previously cached page by executing REST request with paging parameters - we will get data from offline toolkit. Now I switch offline and try to navigate to the one of cached pages - data is retrieved from cache automatically: Read the complete article here.

Oracle JET Offline Persistence Toolkit – Offline Update Handling by Andrejus Baranovskis

Oracle JET Offline Persistence Toolkit supports offline update, create and delete operations. In this post I will describe update use case. Read previous post related to offline toolkit, where I explain how to handle REST pagination, querying and shredding - REST Paging Support by Oracle Offline Persistence in JET. This gif shows scenario, where we go to offline mode and then changing data in multiple rows. Data update happens offline and each PATCH request is tracked by offline persistence toolkit: As soon as we go online (Offline checkbox value is changed in Chrome Developer Tools) - requests executed while offline are replayed automatically against backend server: We should see, how update flow is implemented in JET in this particular case. Once data is changed, we call submitUpdate function. This function in turn calls JET Model API function save. This triggers PATCH call to back-end to update data. If we are offline, JET offline persistence toolkit, transparently records PATCH request to be able to replay it later while online. There are no specific code changes needed by developer to support offline logic during REST call: Read the complete article here.

Classification – Machine Learning Chatbot with TensorFlow by Andrejus Baranovskis

Visual conversation flow is a first thing to create, when you want to build chatbot. Such flow will help to define proper set of intents along with dialog path. Otherwise it is very easy to get lost in conversation transitions and this will lead to chatbot implementation failure. Our chatbot for medical system doesn't make any decisions, instead it helps user to work with enterprise system. It gets user input and during conversation leads to certain API call - which at the end triggers enterprise system to execute one or another action. If user is looking for patient blood pressure results, chatbot will open blood pressure module with patient ID. If user wants to edit or review blood pressure results in general, chatbot will load blood pressure results module without parameters. This kind of chatbot is very helpful in large and complex enterprise systems, this helps to onboard new users much quicker without extra training for system usage. Example of visual conversation flow for chatbot: Conversation intents can be logged in JSON file. Where you should list conversation patterns mapped with tags, responses and contextual information. Chatbot is not only about machine learning and user input processing, very important is to handle conversation contextual flow and usually this is done outside of machine learning area in another module. We will look into it later. Machine learning with neural network is responsible to allow chatbot to calculate tag probability based on user input. In other words - machine learning helps to bring the best matching tag for current sentence, based on predefined intents patterns. As long as we get probability for the intent tag - we know what user wants, we can set conversation context and in the next user request - react based on current context: Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

Detect User Language : Oracle Bots by Soham Dasgupta

Oracle Bot comes with a very sophisticated language detection and translation service. You can attach either a Microsoft or Google service to the environment and make use of it within your bot. Oracle Bots dev guide talks about it here. But, these translation services are not free. So for my development purposes I created a custom component, which does the same for me but for FREE. Introducing Yandex APIs (https://tech.yandex.com/translate/). It is simple and easy to use. And most importantly it is free. Yandex supports over 90 different languages. The only thing you need to do is, register and create an API key for yourself. Step 1: Register and create an API key : https://translate.yandex.com/developers/keys Step 2: Download the custom component from my GitHub here. Step 3: Update the "detect_language.js" and add your key to the detectLanguage() function. Read the complete article here.

Bot Design Patterns : Multi-bot approach by Soham Dasgupta

Oracle Bots comes with platform Translation services, which you can connect to Google or Microsoft services to translate the bot to user default locale. But what if you want to control this auto-translation and restrict the bot to only a few languages. Or want to do Intent matching properly or extracting the Entities properly depending on the language. In the following Bot Design pattern, I will explain how to approach a development of an Oracle Bot which support multiple languages with different Intents and Entity sets. Before I start, I have to give credit to Oracle A-Team for this, they are the one who first introduced this, I am merely a message-borrower in there. So special thanks to Tamer Qumhieh and Steven Davelaar. The Situation You need to create a bot which can respond to multiple languages, with proper Intent matching and Entity identification. Also, the implementation later can be extended to new languages with minimal changes to existing bot implementation. The Pattern You need to create a Master-Bot, which will hold the Intents, Entities, Dialog Flow, Custom Component mapping and Channel(Facebook, Webhook) mapping of the bot. Then you need to create language specific bots, which will only hold Intents and Entities(optionally, only if you have a requirement to match language specific entities).

Build a Chatbot in Minutes Get started with Oracle Intelligent Bots in Oracle Mobile Cloud Enterprise. By Frank Nimphius

2017 was a banner year for chatbots, and 2018 is expected to be another one. Young people in particular refuse to download specific mobile applications just to get in touch with specific organizations. In the same way they communicate with friends and social media followers, young people like to use speech or messengers such as Facebook to book, buy, order, or complain about products and services. Leveraging conversation as a channel for business has become a necessity for organizations to stay connected with this new generation of consumers. Many companies, especially those that focus on customer service, have already reacted to the trend and added chat capabilities to their websites. But how scalable is customer service where each incoming customer message is answered by a human? If message volume exceeds the human capacity to handle it, customers would likely experience the same delays and frustrations users experience when waiting on traditional call centers for an agent to pick up and handle the call. This is where chatbots can help, because their job is to automate conversation between users and services on the conversational channel. So what is a chatbot? A chatbot is computer program that simulates a conversation with a human to serve users on the conversational channel. Often, chatbots are associated with artificial intelligence and machine learning. Though you could easily build bots without these technologies, the majority of chatbots are built based on artificial intelligence and machine learning in order to understand the intent of and extract information from user input, which in most cases is free text or speech. Oracle Intelligent Bots is a feature of Oracle Mobile Cloud Enterprise—which is part of Oracle Cloud Platform—for building multichannel mobile back ends and bots. Using Oracle Intelligent Bots and following the instructions in this article, you are going to build a pizza bot that leverages artificial intelligence and machine learning to understand user intent and to extract values from user input. To access Oracle Intelligent Bots, sign up for a free Oracle Mobile Cloud Enterprise trial. About the Sample Bot Following the steps in this hands-on article, you will build a simple pizza bot.

Run Fn Functions on K8s on Google Cloud Platform by Eugene Fedorenko

  Recently, I have been playing a lot with Functions and Project Fn. Eventually, I got to the point where I had to go beyond a playground on my laptop and go to the real wild world. An idea of running Fn on a K8s cluster seemed very attractive to me and I decided to do that somewhere on prem or in the cloud.  After doing some research on how to install and configure K8s cluster on your own on a bare metal I came to a conclusion that I was too lazy for that. So, I went (flew) to the cloud. In this post I am going to show how to run Fn on Kubernetes cluster hosted on the Google Cloud Platform. Why Google? There are plenty of other cloud providers with the K8s services. The thing is that Google really has Kubernetes cluster in the cloud which is available for everyone. They give you the service right away without asking to apply for a preview mode access (aka we'll reach out to you once we find you good enough for that), explaining why you need it, checking your background, credit history, etc. So, Google. Once you got through all formalities and finally have access to the Google Kubernetes Engine, go to the Quickstarts page and follow the instructions to install Google Cloud SDK. If you don't have kubectl installed on your machine you can install it with gcloud: gcloud components install kubectl Follow the instructions on Kubernetes Engine Quickstart to configure gcloud and create a K8s cluster by invoking the following commands: Read the complete article here.   Developer Partner Community For regular information become a member in the WebLogic Partner Community please visit: http://www.oracle.com/partners/goto/wls-emea ( OPN account required).

Functions-as-a-Service – What SOA Should Have Been by Sherwood Zern

Introduction It wasn’t that many years ago that service-oriented architecture (SOA) was the hot, new, bleeding edge enterprise computing paradigm. Most organizations and vendors jumped on that bandwagon and everything became “service-oriented”. Organizations and vendors both made great claims about how SOA would revolutionize the way applications were built, the amount of reuse that would be achieved, and how application time to market would be greatly reduced. In addition, applications built with SOA technology were supposed to be easier to scale dynamically and those businesses that embraced SOA would see vast improvements in the relationships between IT and the business. Unfortunately, the promises of SOA did not quite pan out across the board. Obviously, some organizations were successful, but far too many did not realize the promised benefits. There are many reasons why some succeeded and some failed but based on many years of first-hand experience building SOA applications and helping numerous customers with SOA-related challenges, here are three common reasons I noted those less than successful SOA projects: 1. Service Granularity. Organizations had a difficult time in defining what would be a service. Eventually, everything that was developed was referred to as a service. In a SOA environment, a service has versioning rules, is put under governance, and is normally categorized as intra-departmental, interdepartmental, or enterprise. To say that all developed code is a service would be overkill and it would mean tremendous overhead from an organizational and administrative perspective. Therefore, deeming everything a service normally means that none of this is put in place and the term service has no real SOA meaning. 2. Distributed Systems complexity. Developers had to be capable of understanding the complexities of distributed systems and the technologies involved with implementing distributed systems, think of transactions and security. Therefore, instead of focusing on implementing business logic a lot of effort was exhausted in worrying about the underlying technologies. 3. Scalability. The majority of “services” developed were deployed within application servers. This author is not saying application servers are bad but if one or two of the services needed to be scaled up or down it meant scaling the application servers. The scaling of application servers could be expensive, and most application servers cannot scale dynamically. The discussion in recent years has shifted from SOA to Microservices to Serverless and Functions-as-a-Service (FaaS). It is this author’s opinion that these technologies are really the next phase of SOA, maybe even what SOA should have been in the first place. Microservices and FaaS deliver on many of the promises that SOA had originally marketed; dynamic scaling, focus on the business logic and not the underlying technologies, and bounding the context of the service. What follows will place emphasis on FaaS (Microservices will be discussed in follow-up blogs) and the open source Fn Project backed by Oracle. Functions-as-a-Service A function is a simple piece of code that does one job, well. These functions are self-contained units of work. FaaS is a category of cloud services that raise the abstraction level so that developers focus on business logic and not think about servers, VMs, or other IaaS components. These functions are then deployed to the platform as containers. Fn Project The discussion which follows is about the Fn Project. Fn is a lightweight, open-source serverless compute platform, that can be deployed to any cloud and on-premise. It is simple, elegant, and extensible by design. This is an OSS project backed by Oracle. All development is in the open. Let’s begin by going through a simple scenario of building a function, testing, and deploying it locally. The scenario is a simple one, but the example can serve as the basis for any type of function and can be extended to more complex functions. What is implemented in the function is not important, but rather how to package, deploy, and run the function on the FaaS platform. In order to demonstrate the end-to-end flow, and not worry about an external cloud service, the sample will run the Fn server locally. This is a very powerful feature of the Fn project. What is tested locally will execute the same way in the cloud. In order to get started follow the instructions to download the Fn CLI and start the Fn server. This information can be found at Fn Project. In order to execute Fn you need to have the following: • Docker installed • Docker Hub Account or another Docker compliant registry. You can even install the Docker container to run a registry locally. If you are planning to only do local development, testing, and deployment then this prerequisite is not a requirement. The screenshot below shows the start of the local running Fn Server. The server listens on port 8080 and this cannot be changed if you are using the `fn start` command. To run on another port, you can start the server directly using `docker start` (see instructions here). Therefore, if you have other components listening on port 8080 then you will have to shut down that component.

Shredding and Querying with Oracle Offline Persistence in JET by Andrejus Baranovskis

I think offline functionality topic should become a trend in the future. Its great that Oracle already provides solution for offline - Oracle Offline Persistence toolkit. This is my second post related to offline support, read previous post - Oracle Offline Persistence Toolkit - Simple GET Response Example with JET. I have tested and explained with sample app how it works to handle simple GET response offline. While today I would like to go one step further and check how to filter offline data - shredding and querying offline. Sample app is fetching a list of employees - Get Employees button. It shows online/offline status - see icon in top right corner. We are online and GET response was cached by persistence toolkit: We can test offline behaviour easily - this can be done through Chrome Developer Tools - turn on Offline mode. Btw, take a look into Initiator field for GET request - it comes from Oracle Offline Persistence toolkit. As I mention it in my previous post - once persistence toolkit is enabled, all REST calls are going through toolkit, this is how it is able to cache response data: Read the complete article here.

JET 4.1 : How to Setup a Functional Application Architecture by Luc Bors

This week I had some interesting Oracle JET discussions with a couple of developers at one of our customers. One of the things was regarding the inline use of CSS that I found in the Views of the Modules. I didn't think that made sense so, after asking, I was told that this was because they did not find a way to use specific CSS per module. The question was if it was possible to use one specific CSS per Module in an Oracle JET Application. Besides that I thought it might also be useful to put everything that belongs to a module in its own folder. That could help developers to get a better understanding of the structure of the application. Besides that it is more like the structure of Oracle JET Composite Components where also everything that belongs to that component is under one folder. Obviously this should be possible by explicitly loading a CSS in the view of the module. Geertjan already blogged about it : https://blogs.oracle.com/geertjan/referencing-css-from-an-oracle-jet-module. The same goes for restructuring the JET application into a more functional architecture: https://blogs.oracle.com/geertjan/restructuring-of-oracle-jet-applications So nothing really new here, although it is a slightly different approach.
