This idea has been merged into another idea. To comment or vote on this idea, please visit DB24ZOS-I-1540 Resolve issue where DB2 has an issue with invalid MDSNxx Class profiles created in RACF.

Correct how zOS DB2 is processing commands from RACF permission adminisration Merged

IBM Please read the case TS013914362.

In summary DB2 created dumps/abends when the RACF administrator deleted permissions to some incorrectly formatted profiles in one of the MDSNxx classes. When the administrator performed the permit delete and issued the SETROPTS command a signal was sent to DB2 to update its internal tables. It could not decypher the profile so a dump/abend was created. The profile did not have the correct number of nodes.

From a RACF Security Engineer perspective, DB2 is using RACF incorrectly. RACF is a repository of profiles, it is not a profile syntax checker. If you create a invalid JESJOBS or JESSPOOL profile, JES2 does not abend. The profile is just not used because the resource being checked does not match the profile. The same with other products like CICS, MQ, IMS, etc. They don't abend when administration is performed on a invalid profile.

DB2 needs to re-look at how it interfaces with RACF.

    TS013914362 was updated on 9/18/2023. We experienced another abend with DB2, but this event appears to be for the RDELETE command on a MDSNSP profile that was only 3 nodes long which is incorrect. It appears the DB2 cannot address invalid profiles existing in the RACF MDSN* classes.
