Update: There is now a bundle patch available that contains all the recommended patches on top of BPM 126.96.36.199 – the patch number is 9958661 and this patch should be installed in preference to the individual patches listed below.
A number of customers have reported some issues with memory usage on SOA or BPM 11g (188.8.131.52 and 184.108.40.206) after a number of composite deployments or redeployments. This tends to only occur in development environments where you are frequently deploying changed composites.
The observed symptom is that memory use grows after each deployment, until eventually you run out of memory and you will get an error on the managed server (OutOfMemoryException or a PermGen error) and the managed server will shutdown. After restarting the managed server, the memory usage returns to a lower level.
The workaround for this (of course) is to restart the managed server more frequently to free up the used memory. But this can be a bit inconvenient!
Three patches have been released that address these issues. These can be applied on top of 220.127.116.11 (on any platform, 32-bit or 64-bit). If you want a specific platform version or a patch for 18.104.22.168, you can search for these patches on Oracle Support and follow the links to other versions.
The patch numbers are as follows:
You can find all of these on Oracle Support, by searching by number on the Patches tab.
