Clear Cache WLS

Before deleting any directory, you need to shutdown all servers first.

The following provides a generic example path to the tmp directory in question:

WINDOWS: 
cd C:\wls\user_projects\domains\servers\

UNIX:
cd /wls/user_projects/domains/servers/

The following would be used to clear the cache:

WINDOWS:  
rd C:\wls\user_projects\domains\servers\tmp
rd C:\wls\user_projects\domains\servers\cache

UNIX: 
rm -rf /wls/user_projects/domains/servers/tmp
rm -rf /wls/user_projects/domains//servers/cache


 For WLS versions 9.2 and above, delete the following Admin and Managed server cache directories:

    /servers/cache
    /servers/stage (if exists)
    /servers/tmp
