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.

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.

Using the MetaData Services (MDS) in a SOA environment by Robert van Molken

It has been almost a year since my last post about the metadata services. I talked about how-to set up a File-based MDS and DB-based MDS. This post talks about the usage of the files, placed in the MDS, in the different components available in a SOA composite. If the MDS is a new thing for you then I advise to read my previous about this subject first.

You can spot the presence of a file that is a reference to the MDS if it uses the oramds: URI annotation. Files are no longer referenced to a hardcoded or relative file path.

To start using you’re MDS that you have set up we will create a new SOA application. Let call the application WorkflowSOAapp and create a SOA project and call it WebformService.

Use MDS resources for exposed services

After creating the new SOA project it will open the composite editor automatically. Exposed services are always created in the left swim lane. Because this project deals with a WSDL resource to expose a webservice, a Web Service component is first dragged to the left swim lane.

Create exposed service

Drag Web Service Component to left swimlane

A dialog “Create Web Service” will open. Give the service a good name, preferred the same as the name in the WSDL (e.g. WebFormService). The next thing to do is to choose the WSDL URL. Click on the document jdev_document_iconicon at the right side of the WSDL URL input to find an existing WSDL. Read the full article here & Read part II here.
