OPTIONS

       -id
              Use 'lsinventory' option to display all patch id's.
              Each one-off patch is indicated by its id. To rollback
              a patch the id for that patch must be supplied. A comma
              separated list of patches to be rolled back must be given.

       -init
              This option is used to pass parameters to the init
              script. This script is executed before prerequisite checks
              are run. The value for this option have to be enclosed
              in double quotes. The parameters will be common parameters 
              which will be passed to pre scripts of all patches being 
              rolled back.

       -jre
              This option tells OPatch to use JRE (java) from the
              specified location instead of the default location
              under Oracle Home. 

       -no_relink
              Do not perform the make operations in the patch. This
              option can be used during multiple patch removals and
              perform the compilation step only once.

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

       -opatch_init_end
              This option is used to mark the end of init options.
              Without this option everything after init till end of
              the command is passed into init. This option is
              meaningless without -init option.

       -opatch_post_end
              This option is used to mark the end of post options.
              Without this option everything after post till end of
              the command is passed into post. This option is
              meaningless without -post option.

       -opatch_pre_end
              This option is used to mark the end of pre options.
              Without this option everything after pre till end of
              the command is passed into pre. This option is
              meaningless without -pre option.

       -post
              This option is used to pass parameters to the post
              script.  This script is executed after removal of the
              patch. The value for this option have to be enclosed
              in double quotes. The parameters will be common parameters 
              which will be passed to post scripts of all patches being 
              rolled back 

       -pre
              This option is used to pass parameters to the pre script. 
              This script is executed before removal of the patch. The
              value for this option have to be enclosed in double quotes.
              The parameters will be common parameters which will be
              passed to pre scripts of all patches being rolled back.

       -property_file
              The user defined property file for OPatch to use. The
              path to the property file should be absolute. This
              property file takes precedence over the one that is
              supplied with OPatch.

       -report
              Just prints out the actions, without executing.

       -silent
              This suppresses any user-interaction and defaults any
              Y|N question to Y. This option is not supported on
              RAC yet.

       -verbose
              This option prints more OPatch output to the screen
              as well as to the log file.
