RECOVERY_DATA

   Deletes one or more patch recovery data sets in order of creation
   date, starting with the oldest one first. A recovery data set
   is created when a patch kit is successfully installed with the
   /SAVE_RECOVERY_DATA qualifier. Recovery data sets are used to
   uninstall patches when you use the PRODUCT UNDO PATCH command.

   Note that once patch recovery data is deleted, you cannot
   uninstall any patch that is associated with this data. Installed
   patches are not affected when you use the PRODUCT DELETE
   RECOVERY_DATA command.
