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.

    Format

      PRODUCT DELETE RECOVERY_DATA  [/qualifiers]

1  –  Parameters

    None.

2  –  Qualifiers

2.1    /ALL

       /ALL (default)

    Selects all patch recovery data sets to be deleted. The recovery
    data is deleted in the order it was created, starting with the
    oldest set first. If you omit this qualifier from the command
    line, the effect is the same as if you specified it.

2.2    /BEFORE

       /BEFORE=time

    Selects patch recovery data sets created before the specified
    date and time. You can specify time as an absolute time, as
    a combination of absolute and delta times, or as one of the
    following keywords:

        TODAY (default)
        TOMORROW
        YESTERDAY

    For information about specifying time values. see the OpenVMS
    User's Manual.

2.3    /OPTIONS

       /OPTIONS=keyword
       /NOOPTIONS (default)

    Specifies PRODUCT command options. The keyword is:

    NOCONFIRM        Omits the confirmation dialog that asks the user
                     to verify the recovery data sets that have been
                     selected for processing.

2.4    /LOG

       /LOG
       /NOLOG (default)

    Displays the file specifications of the files within the recovery
    data sets that are being deleted.

2.5    /OLDEST

       /OLDEST=count

    Specifies the number of oldest recovery data sets that you want
    to delete. For example, if you specify /OLDEST=2, the PRODUCT
    DELETE RECOVERY_DATA command deletes the two oldest recovery data
    sets. If you do not specify a number with this qualifier, the
    default value is 1.

2.6    /REMOTE

       /REMOTE
       /NOREMOTE (default)

    Selects recovery data sets located on a privately mounted system
    disk. By default, PCSI searches the currently booted system disk
    for recovery data sets.

    When you use /REMOTE, the following logical names must be
    defined:

    o  PCSI$SYSDEVICE must specify the physical disk name of the
       target system disk. This disk must be mounted and allocated to
       the process executing the PRODUCT command.

    o  PCSI$SPECIFIC must point to a system root on PCSI$SYSDEVICE.
       It must be defined in the following form, where x is a valid
       system root:

       PCSI$SYSDEVICE:[SYSx.]

3  –  Example

  $ PRODUCT DELETE RECOVERY_DATA /OLDEST=2

      The command in this example deletes the two oldest recovery
      data sets starting with the one that was created first,
      followed by next oldest recovery data set. If, for example,
      three patch recovery data sets are on the system disk, you
      still have one set preserved after this operation completes.

      Remember that once a patch recovery data set is deleted, you
      cannot uninstall the patch kit associated with the deleted
      recovery data. The installed patch kits, however, are not
      affected by this action.
