All FMW products except the WebLogic server is patched via the opatch tool. From FMW 12.1.2 the WebLogic server is also patched by opatch.
In a FMW installation you can have many Oracle Homes. When you install a patch you need to know which home to apply the patch to.

When you deinstall a WebLogic server the path is not removed from beahomelist, but next time you install (more...)

I recently had to find the size of the data stored in the HTTP Session State. On MOS I found this note:
“Session Replication Fails Due To Non-Serializable Object: JSP Test Page [ID 1073386.1]“.
It contains a JSP test page that will show you if your session data is (more...)
I recently had to upgrade a WebLogic Server with ADF for a customer. It was WebLogic 10.3.4 to 10.3.6 and ADF 126.96.36.199 to 188.8.131.52. They also used Enterprise Manager.
Everything went fine except for the Enterprise Manager which ended up (more...)
