Recently I was involved in an Oracle Fusion Middleware upgrade from 11g PS2 to 11g PS5 with Jacco Landlust, Aiman Salama, and Jens Peters. The environment that was patched consists of the following domains:
The domains consist of several Managed Servers in a single-node cluster configuration. OSB and SOA Suite both run in their own Managed Server.
There are plenty of excellent blogs that discuss the infrastructure and middleware side of such an upgrade. This blogs contains some things we encountered from the application side of things. More specific, the SOA composites and OSB projects.
Rebuild custom Java classes and JAR files in the SOA extension library
You can add custom Java classes and JAR files to SOA Suite that are used by your SOA composites. The SOA extension library for adding extension classes and JARs is available in the $ORACLE_HOME/soa/modules/oracle.soa.ext_11.1.1 directory. For example, an extension can be used to add a custom fault handler. Read the full article here.
