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.
