In-depth look into Oracle API Catalog (OAC) 12c by Robert van Molken


clip_image002With the release of Oracle Enterprise Repository 12c another product was released. Oracle API Catalog 12c (OAC) allows you to build a catalog of your organization APIs. OAC provides a layer of visibility to those APIs so application development knows what and which one to use.  OAC includes a simple metamodel for an API asset, automation to populate OAC, and the ability for users to search OAC for APIs and understand the details of the APIs to assess their fit in the user’s application.

Installation

I’m not going to bore you with the details about the installation by giving a installation guide. It took me about 40 minutes from scratch (excluding downlOERoad time). The steps are describes in the installation guide Oracle provides. OAC is part of the OER 12c installation jar, but can be licensed and installed, as an own managed domain, without licensing and installing OER.

The steps to take on high level (from scratch):

  1. Download and install Oracle Database, Fusion Middleware Infrastructure 12c, Oracle Enterprise Repository 12c, RCU patch 18791727 and Weblogic patch 18718889 (these last two are important, else you can’t install OAC).
  2. Run RCU (oracle_common/bin/rcu.sh|bat) and create the OAC repository
  3. Run Weblogic Domain creation (weblogic/bin/config.sh|bat) and create a new which includes OAC.
  4. After installation and startup of weblogic and managed service you can find the OAC console at url: http://serverhost:8111/oac

Note: if you harvesting from another weblogic server (like SOA Suite 12c), the weblogic patch should also be installed there.

Taking the first steps

When taking my first steps the official getting started guide can help you a lot. OAC has four high-level features. OAC collects services, it has a harvester which creates API assets in OAC. After harvesting you can add metadata to the API assets like description, tags and documentation. After harvesting and editing an API asset it can be published so it is visible for application development. Published APIs can be discovered and used  through the API Catalog console and via the Oracle JDeveloper Oracle Enterprise Repository plug-in.

BPM & SOA Application missing in JDeveloper 12c gallery by Martien van den Akker

clip_image001

A few weeks ago I did a BPM12c Quickstart Installation under Oracle Linux 6. Everything went smoothly, as described in the install guide as well as on many blogs already.
But I found that most of those blogs did an installation under Windows, where I did it under Oracle Linux in Virtualbox.
You would think (as I did) that it shouldn't matter. However, it turns out that in JDeveloper I was missing the 'BPM Application' amongst others in the JDeveloper New Gallery. Very inconvenient. I couldn't find any hints on the big internet. My friend Google wasn't very helpful in this.
But I wouldn't write this blog if I did not solve it. It turns out that with an update I got it solved.
It turns out that I lacked the 'Spring & Oracle Weblogic SCA' extension. Using the Help->Update functionality I downloaded and installed that and after restarting JDeveloper my 'New Gallery' was properly filled.
For those not so familiar with the JDeveloper update mechanism, here a step by step guide:

OSB12c: Errorhandling in REST by Martien van den Akker

clip_image002Yesterday, I had an OSB consulting day at a customer. We looked into a REST service that was to be extended with update functionality. Since calling an update service of an EIS (Enterprise Information System) can go wrong with all sorts of errors, it is important to be able to return a fault-message with the errors, jason format.
Now in OSB12c it's very apparent how you define possible fault-messages and even how the should be formatted in JSON:

In this sample case we created a more or less simple xsd for faults (dutch: fouten). To test with different fault messages we simply duplicated the 'fouten' element in the xsd to 'fouten2'. You can assign different HTTP-status codes to the different fault.
So this is configuration is pretty simple and straight forward. But it is not quite clear in the documents how you would return a specific fault within your error-handlers in the pipeline.
Internally OSB works not only 'XML'-based but actually SOAP-based. So the trick in the end is to replace the body with a soap-fault message and the selection of the REST/JSON errormessage is done based on the structure of the document in the details-section of the SOAP-Fault. In the screen above, you would define for each fault message an xsd-element and apparently it validates the soap-fault-details content against each XSD defined, and the xsd against which the detail-content is valid points to the returned fault, with the corresponding HTTP Status.

API Management – An Overview of API Catalog and API Manager at Fusion Middleware Partner Community Forum 2015

The Fusion Middleware Partner Community Forum takes place March 3rd & 4th in Budapest Hungary. During this annual conference You as an Oracle Partner can get the latest updates on the Fusion Middleware 12c solutions. “The Cloud Platform for Digital Business” will be the theme of the 20th conference. Keynotes will be delivered from Amit Zavery, Andrew Sutherland and SOA, BPM and Mobile product management including live demos. On the second day you can choose between three tracks: SOA, BPM or WebLogic and Mobile. As part of the SOA track Robert and Yogesh will present:

Oracle API Management – An Overview of API Catalog and API Manager incl. a demo

Mobile applications increasingly use Application Programming interfaces (APIs) in addition to enterprise systems of record in their development. The importance of an API economy is growing by the day. As the number of APIs produced and consumed by enterprises increases, thanks to an exponential growth of mobiles, tablets, smart devices and computing platforms, the management and visibility of these APIs becomes increasingly important.

Oracle API Catalog (OAC) and the upcoming Oracle API Manager allow organizations to easily manage their APIs and build a catalog of their APIs, powered by the industry leading Oracle Service Bus backbone (in case of API Manager), thus providing visibility and control to the enterprise and a social catalog to API consumers for application development. Come and find out more on this session, incl. the exciting demo.

JSON is flowing through SOA’s veins by Laurens van der Starre

This year’s Oracle Open World is again all about Cloud and Mobile. However, this year it is getting more and more concrete. Apart from all the announcements of Process Cloud and integration cloud services there will be more JSON support in Oracle’s SOA Suite.

In Oracle SOA Suite 12C (12.1.3) the REST Adapter already made its appearance. This adapter makes it make your SCA component available as, and leverage REST services, using JSON. This JSON support starts and end with the REST adapter. Inside your SCA components, it is still XML.

In the second release of Oracle SOA Suite 12C (12.1.4) there will be JSON flowing through all the veins of the SCA components. In Service Bus, you will be able to have JSON context variables. Instead of only having xpath operations on your context variables, you have the ability to use JavaScript. There will also be a JavaScript activity which lets you write JavaScript “transformations” on your context variables.

The same goes for BPEL. BPEL is heavily based on XML, but here also the JSON support will be end-to-end. Pretty exiting, but also scary because of the “unstructuredness” of JSON.

Oracle SOA Suite 12.1.4 will probably available in H1 of 2015.

Patching the Oracle Service Bus 12.1.3 unknown protocol deployment error by Jan van Zoggel

If you (already) created your first Oracle Service Bus 12c application/project with SOAP webservices and tried to deploy it to your IntegratedWeblogic server you might be familiar with this error.

clip_image002

Lucky for us Oracle quickly released a solution on their support website and also various blogs picked it up and posted a solution. The earliest reference I found was posted by Link. The solution to your problem was either:

  • Add felix.service.urlhandlers=false to the Init properties of OSGi frameworks bac-svnserver-osgi-framework factory implementation class
  • Remove the default server as a target for the framework

This worked like a charm and I was able to play around with my 12c Service Bus. However since it was stated that the solution could result into problems with BPM on your domain I reminded myself that I wanted to dive deeper into this when I had the time.

Google helped me out, and I discovered this information on the Apache Felix framework website.

Felix installs the URL Handlers service by default. If you do not want this service you can disable it, by setting the felix.service.urlhandlers property to false in the config.properties file. It is not recommended to disable this, but the main reason for doing so it because the URL Handlers implementation invokes methods to set the singleton factories for URL stream and content handler factories. Assuming that you want to use URL Handlers service, you must configure it if you aren’t running on the standard Sun JRE. Read the complete article here.

Create Service Bus Customization File using WLST by Ronald van Luttikhui

clip_image002For one of our Oracle Fusion Middleware projects we had the requirement that the IT Ops activities should be scripted as much as possible. These activities included things like packaging, deploying, and automated testing of Service Bus projects, SOA Composites, and BPM processes. One of the more challenging tasks to script was to create and extract the runtime configuration of services deployed on Oracle Service Bus 11g using customization files. There seems to be no WLST feature readily available for this purpose. Based on some resources that all contained part of the solution, we were able to construct a WLST script for this purpose which you can find in this blog.
This blog briefly explains the use of customization files, how to create a customization file using the Service Bus Console, includes the WLST script to execute this task, and provides a brief conclusion.

Customization Files

Customization files are XML files that contain the configuration of Service Bus resources and projects. Examples of such configurations are Service URIs, JCA settings, Retry Settings, and so on. Customization files provide a convenient way to apply environment-specific configuration during deployment. You can both apply, as well as create and extract the runtime configuration of Service Bus resources and projects into customization files using the Service Bus Console.

Set-up a 12c Service Bus Infrastructure by René van Wijk

imageIn this post, we will show how to create automation scripts in order to set-up middleware environments.
Preparation
In the example, we will use the following software

First, we have to decide which directory structure we are going to use. Below an example is given in which the binaries (that create the run-time) are separated from the configuration. Read the complete article here.
