How to clean up patch history?

If you are applying any CPU, PSU, or interim patches, OPatch will consume a large amount of disk space under $ORACLE_HOME/.patch_storage. To perform a cleanup, use the file orapatch.util.cleanup. The folder patch_storage contains the backup of the affected libraries and modules that have been updated. Cleanup can be performed as follows:

[oracle@oracle-primary ~]$ opatch util cleanup
Oracle Interim Patch Installer version 11.2.0.3.0

................
Invoking utility "cleanup"
OPatch will clean up 'restore.sh,make.txt' files and 'rac,scratch,backup' directories.
You will be still able to rollback patches after this cleanup.
