As you might be aware, a few days back we released Patchset 2 (PS2) for several products in the Oracle Fusion Middleware 11g Release 1 stack including WebLogic Server and SOA Suite. Though there was no patchset released for Oracle Service Registry (OSR) 11g, being an integral part of Fusion Middleware & SOA, OSR 11g R1 ( 11.1.1.2 ) is fully certified with this release. Below is some recommended reading before installing OSR 11g with the new PS2 :

OSR 11g R1 & SOA Suite 11g PS2 in a Shared WebLogic Domain
If you intend to deploy OSR 11g in the same domain as the SOA Suite 11g, the primary recommendation is to install OSR 11g in its own Managed Server within the same Weblogic Domain as the SOA Suite, as the following diagram depicts :

An important pre-requisite for this setup is to apply Patch 9499508, after installation. It basically replaces a registry library - wasp.jar - in the registry application deployed on your server, so as to enable co-deployment of OSR 11g & SOA Suite 11g in the same WLS Domain. The patch fixes a java.lang.LinkageError: loader constraint violation that appears in your OSR system log and is now available for download.

The second, equally important, pre-requisite is to modify the setDomainEnv.sh/.cmd file for your WebLogic Domain to conditionally set the CLASSPATH so that the oracle.soa.fabric.jar library is not included in it for the Managed Server(s) hosting OSR 11g.

Both these pre-requisites and other OSR 11g Topology Best Practices are covered in detail in the new Knowledge Base article Oracle Service Registry 11g Topology : Best Practices.

Architecting an OSR 11g High Availability Setup
Typically you would want to create a High Availability (HA) OSR 11g setup, especially on your production system. The following illustrates the recommended topology.

The article, Hands-on Guide to Creating an Oracle Service Registry 11g High-Availability Setup on Oracle WebLogic Server 11g on OTN provides step-by-step instructions for creating such an active-active HA setup of multiple OSR 11g nodes with a Load Balancer in an Oracle WebLogic Server cluster environment.

Additional Info
The OSR Home Page on OTN is the hub for OSR and is regularly updated with latest information, articles, white papers etc. For further reading, this FAQ answers some common questions on OSR.

The OSR Certification Matrix lists the Application Servers, Databases, Artifact Storage Tools, Web Browsers, IDEs, etc... that OSR 11g is certified against.

If you hit any problems during OSR 11g installation, design time or runtime, the first place to look into is the logs. To find more details about which logs to check when & where, take a look at Where to find Oracle Service Registry Logs?

Finally, if you have any questions or problems, there are various ways to reach us - on the SOA Governance forum on OTN, on the Community Forums or by contacting Oracle Support.
