I receive message ACF79482 or ACF79483 when I refresh any GSO records. I also receive the same messages at ACF2 startup and at midnight every day. Why?

Messages ACF79482 and ACF79483 are introduced to ACF2 r15.0 by apar RO62039. The messages are provided to aid in readiness for the implementation of z/OS 2.1 which removes the use of the default OMVS user ( BPX.DEFAULT.USER )


ACF79482 will be issued if you are running z/OS 1.13 or below
ACF79483 will be issued if you are running z/OS 2.1 or above

ACF79482 BPX.DEFAULT.USER values defined - They become obsolete at z/OS 2.1 and above


ACF79483 BPX.DEFAULT.USER values defined - They are ignored at z/OS 2.1 and above

The IBM BPX.DEFAULT.USER feature provides a method of assigning (and sharing) default user identifiers (UIDs) or group identifiers (GIDs) among UNIX SystemServices users or groups when needed. In z/OS 2.1 and above, the feature is not supported. As of z/OS 2.1, the defaults that are defined in the UNIXOPTSrecord are obsolete. Users who had been using the default can no longer access Unix System Services.

This message appears in the following situations:

  • Every time a GSO record is refreshed (even if the record is not UNIXOPTS or AUTOIDOM)
  • During every CA ACF2 startup and at midnight every day (until the defaults are removed from the UNIXOPTS record)

Ensure that all UNIX System Services users are assigned a UID. Ensure that all users have a GROUP field on the logonid that has a GID defined. You can use the AUTOIDOM record to automatically assign UID and GIDs, and you can use the UNIXOPTS record to ensure that new OMVS profile records are automaticallygenerated with UIDs and GIDs.

Note: For more information about configuring the AUTOIDOM and UNIXOPTS records, see the CA ACF2 Administration Guide.
If all users have been assigned a UID and GROUP value and the GROUP is assigned a GID, remove the DFTUSER and DFTGROUP fields from the UNIXOPTS record toeliminate this message.
