Oracle Interim Patch Installer version 12.2.0.1.21

DESCRIPTION
     This utility cleans up 'restore.sh,make.txt' files and 'scratch,backup'
     directories of the.patch_storage directory of Oracle Home.If -ps option is used,
     then, it cleans the above specified areas only for that patch, else for all
     patches under ORACLE_HOME/.patch_storage. You will be still able to
     rollback patches after this cleanup.

SYNTAX
opatch util cleanup  [-invPtrLoc ]
                     [-jre ] [-oh ]
                     [-silent] [-report]
                     [-ps , this will
                       be located under ORACLE_HOME/.patch_storage/]

OPTIONS
       -invPtrLoc
              Used to locate the oraInst.loc file. Needed when the
              installation used the -invPtrLoc flag. This should be
              the path to the oraInst.loc file.

       -jre
              This option tells OPatch to use JRE (java) from the
              specified location instead of the default location
              under Oracle Home. Both -jdk and -jre options cannot
              be specified together. OPatch will display error in
              that case.

       -oh
              The oracle home to work on. This takes precedence over
              the environment variable ORACLE_HOME.

       -ps
              This option is used to specify the Patch ID with timestamp.
              This Patch ID with timestamp should be the same as in
              .patch_storage directory.

              A directory by this name will be present under
              ORACLE_HOME/.patch_storage. If this directory is specified
              and is valid, then the contents specified in the description
              will be cleaned up only for this patch. Otherwise, all patch
              related directories will be acted upon by this utility.

      -silent
              In silent mode, the cleanup always takes place.

      -report
              Prints the operations without actually executing them.


OPatch succeeded.
