I'm getting ACF99913 violations when I try to add or delete an ALIAS in the master catalog on z/OS.
If the violation message specifies the ALIAS name, then it is probable that the user is failing on a FACILITY class resource validation for resource STGADMIN.IGG.DEFDEL.UALIAS. This validation is issued by DFSMS. If the user attempting to update the catalog fails this validation, there will be a subsequent validation for the ALIAS name (the HLQ). If the user is allowed access to this resource, there will be no subsequent validation for the ALIAS name. If there is any question about the FACILITY validation, run an CA ACF2 SECTRACE for the FACILITY class.
