Quick Introduction to Oracle Stream Explorer – Business User friendly processing of real time events by Lucas Jellema

clip_image002The new Oracle Stream Explorer provides us with a [business]user friendly facility to process real time events. Through visually appealing and functionally intuitive web wizards, Stream Explorer has us construct explorations that consume events from streams, process these events through filtering, aggregation, pattern matching and enriching and deliver these events to downstream destinations.

Using Stream Explorer, we can tap into streams of events – frequently JMS messages and alternatively HTTP PUB/SUB, SOA Suite EDN events or REST calls. For testing and demo purposes, we can use an CSV file as the source for a stream exploration. A stream is fed into one or more explorations that do the interpretation and processing of the events. A target can be associated with an exploration to have the outcomes of the exploration – which are also events, at a more elevated level after all the processing has taken place – delivered for subsequent action or communication. Destination types available for targets are JMS, REST Service, HTTP Pub (channel) and the EDN of SOA Suite. Again, for development, testing and demonstrations, a CSV file can be set as the target.

In this first introduction to Stream Explorer, we will discuss a very simple challenge: we are organizing a small conference. In three rooms, sessions take place simultaneously. Our attendees are free to decide which session to attend. We would like to know at virtually any moment how many people are in each room. We have set up simple detectors at the doors of the rooms that produce a signal whenever someone enters or leaves the room. This signal consists of the room identifier (1,2 or 3) and an IN/OUT flag (values +1 or -1).

We will use Stream Explorer to process these events and produce an aggregate per room of the net number of people that entered or left the room. In subsequent articles we will do more advanced explorations in this same setting – looking at prematurely concluded sessions, jammed doors, overflowing rooms etc.

Preparation

The preparation consists of the installation of Stream Explorer on top of an OEP domain. Start the OEP Server. The Stream Explorer can be accessed at http://host:port/sx. Login using the same user used for the OEP Events Visualizer web application: wlevs. Read the complete article here.

Cloud Integration by IPT and Oracle

clip_image002The requirement is easily written down: the web page contains a form with multiple form items. Each user should be allowed to personalize the form at run time. This personalization entails the ability to hide and show form items. When user has decided to hide and show specific items – this decision should be persisted across sessions so that when the user logins at a later date, the form items she has hidden are still invisible and the displayed ones displayed.

This article describes how to implement this particular requirement in an ADF 12c Fusion Web Application. Note: the same steps and code will do the job for ADF 11g.

ADF has built in support for customization – both at design time and run time. Customization can be defined at various levels (or layers as the terminology is). One of these layers – typically the most fine grained – is the user level. Customizations at user level are frequently called personalizations.

In order for an ADF web application to support customization and personalization, we have to configure a number of things:

· a user-level customization class has to be configured in the adf-config.xml

· ADF Security has to be configured – so users can be identified (so their personalizations can be stored and retrieved)

· customizations has to be enabled in the properties of the View project

· the specific customization we are interested in (personalizing the visible or rendered attribute on inputText components) has to be enabled in the adf-config.xml file

· a managed bean is configured that receives the updated form item definitions and sends them to the ADF Change Manager that writes them to MDS

· a simple JSF page is developed with a form and a shuttle component to indicate which form items are to be hidden or displayed

The page looks as follows in this example: Read the complete article here.

BPM Suite 12c: Getting started with BPM Studio (JDeveloper) and Process Composer using Process Asset Manager (PAM) by Lucas Jellema

clip_image002We see a clear trend with Oracle BPM Suite that the Process Composer – the browser based modeling IDE – is getting richer in functionality. Before too long, virtually all modeling/design and many implementation activities will be supported by Process Composer. With the upcoming Process Cloud Service where the process is created in its entirety through browser based tooling, this is of course necessary.

It will be a common practice to work on business processes both in Process Composer and in BPM Studio (JDeveloper). Exchanging the process definition between these two environments is essential for smooth collaboration. In this article, I provide some pointers to get going with Process Composer in BPM Suite 12c (12.1.3) and the interaction with BPM Studio – based on the Process Asset Manager (PAM) as well as ‘plain’ export/import.

Getting started with BPM Process Composer

Process Composer is available at http://host:port/bpm/composer.

On the home page, there are several areas that you can step into: business architecture and BPM processes are the main ones. To create a new BPM project, click on the plus icon in the BPM Project title area. Provide the name and description of the project and select an existing or new space.

Rapid creation of Virtual Machine(s) for SOA Suite 12.1.3 server run time environment – leveraging Vagrant, Puppet and Biemond by Lucas Jellema

clip_image002In recent previous articles I have discussed the use of Vagrant and Puppet for the automated creation of Virtual Machines, for example with various Oracle software components completely installed into them. In this article, I am merely the consumer of goodies. Edwin Biemond published on GitHub the complete set of Vagrant and Puppet configuration files for creating VMs with the SOA Infra database (Oracle Database 11.2.0.4, populated with the RCU installer) and the SOA Suite 12.1.3 run time environment – including Service Bus, see: WebLogic 12.1.3 infra (JRF) with SOA,OSB.

In this article, I will describe the steps I took to actually produce the two VMs using Edwin’s scripts. The visual description of the whole process looks something like the next figure: Read the complete article here.

SOA Suite 12c: Actionable Emails with Human Task service by Lucas Jellema

clip_image002It is my assumption that inbound and outbound emailing has been configured – for example for a GMail account – as described in these two articles: GMail for inbound mail in SOA Suite 12c and GMail for outbound mail in SOA Suite 12c and that test mails can be sent and received.

The steps are:

  • configure an email driver for SOA Suite for outbound and inbound emails
  • configure an email address (one of the inbound email accounts set up on the email driver configuration) for actionable emails
  • create a Human Task definition for a task that is configured as actionable; assign this task to a user who has an email configured in the LDAP directory
  • deploy the Human Task as part of a SOA Composite; invoke the composite to have the task assigned to the user
  • the user should receive a notification mail message regarding the task assignment with the option to act on the task by clicking a link in the email; clicking such a link will trigger a response email to the actionable email account with appropriate meta-data for the SOA Suite to interpret the response; the user can even add attachments and comments to this task response mail.

We assume the first setp has been taken care of. Once the email driver for the managed server running SOA Suite has been configured for outbound and inbound email interaction, there is really not a lot to do.

FMW 12.1.3 – Invoking Enterprise Scheduler Service Web Services from SoapUI by Lucas Jellema

clip_image002

The Fusion Middleware 12.1.3 platform contains the ESS or Enterprise Scheduler Service. This service can be used as asynchronous, schedule based job orchestrator. It can execute jobs that are Operating System jobs, java calls (local Java or EJB), PL/SQL calls, and Web Service calls (synchronous, asynchronous and one-way) including SOA composite, Service Bus and ADF BC web services.

Jobs and schedules can be defined from client applications

through a  Java API or through the Enterprise Manager FMW Control user interface. Additionally, ESS exposes a web service through which (pre defined) jobs can be scheduled. This web service can be invoked from BPEL processes in SOA composites – or from any component that knows how to invoke a SOAP Web Service.

In this article I will briefly demonstrate how to invoke the ESS Web Service from SoapUI. I will not describe how to create the Job Definition – I will assume two pre existing Job Definitions: HelloWorld (of type PL/SQL job) and SendFlightUpdateNotification of type SOA composite based one way Web Service. Both Job Definitions contain application properties – parameters that can be set for every job instance and that are used in the job execution. When invoking the ESS Web Service to schedule a job, values for these properties can be passed in.

There is one tricky aspect with ESS: jobs cannot be run as anonymous users. So if ESS does not know who makes the request for scheduling a job, it will not perform the request. It returns an error such as

oracle.as.scheduler.RuntimeServiceAccessControlException: ESS-02002 User anonymous does not have sufficient privilege to perform operation submitRequest JobDefinition://oracle/apps/ess/custom/saibot/SendFlightUpdateNotification.

To ensure we do not run into this problem, we have to attach a WSM security policy to the ESS Web Service and pass a WS Security Header with valid username and password in our request. Then the job request is made in the context of a validated user and this problem goes away.

The steps to go through: Read the complete article here.

Resolving deployment issues with Service Bus 12c – OSB-398016 – Error loading WSDL by Lucas Jellema

I was completely stuck with Service Bus 12c project deployment from JDeveloper to the Service Bus run time. Every deployment met with the same fate: Conflicts found during publish – OSB-398016, Error loading the WSDL from the repository: The WSDL is not semantically valid: Failed to read wsdl file from url due to — java.net.MalformedURLException: Unknown protocol: servicebus.


I was completely lost and frustrated – not even a simple hello_world could make it to the server.
Then, Google and Daniel Dias from Link Consulting to the rescue: http://middlewarebylink.wordpress.com/2014/07/17/soa-12c-end-to-end-e2e-tutorial-error-deploying-validatepayment/. He had run into the same problem – and he had a fix for it! Extremely hard to find if you ask me, but fairly easy to apply.
It turns out this is a known bug (18856204). The bug description refers to BPM and SB being installed in the same domain.
The resolution:
Open the Administration Console for the WebLogic Domain. From the Services node, select service OSGi Frameworks: Read the complete article here.

Setup GMail as mail provider for SOA Suite 12c – configure SMTP certificate in trust store By Lucas Jellema

On this subject, there are already many fine articles. I have borrowed from at least a dozen to understand what should happen and to make it work. You will find them listed under resources.
It all started with me trying to have the UMS Adapter send an email. The setup of the email driver was done in EM FMW Control (see below) and I expected my email to be sent successfully. After a considerable and increasingly anxious wait at my mail client, I decided to check the log file for my WebLogic domain. There it was, in the soa_server1.out for my SOA Suite managed server: Read the complete article here.
