How to clear the WebSphere class caches

IBM Support, may ask you to clear the class cache. There are several reasons for this. After an upgrade, it is possible that the class cache's are still holding onto previous versions of classes. It is also possible that the caches became corrupted.

Please remember there are two caches that will need to be cleared, the JVM's cache and the OSGi cache. The server has to be stopped before clearing the cache.

 To clear the OSGi class cache:
For UNIX platforms, run the following script in each profile:
<WebSphere_HOME>/profiles/profile_name/bin/osgiCfgInit.sh

 To clear the JVM's class cache (Windows, Linux and AIX only) :
For UNIX platforms, run the following script:
<WebSphere_HOME>/bin/clearClassCache.sh
