If you rename, alter, move, recover or change the size of a basic catalog structure when using catalog record-level sharing (RLS), you must use the AMS SHCDS CFREPAIR command to correct RLS information in the catalog. The catalog must be import connected on all systems to the master catalog before the CFREPAIR command can be used. The AMS SHCDS CFREPAIRDS command may be used to correct the RLS information for individual RLS data sets. However, caution must be taken to identify all data sets used as RLS data sets. Otherwise, data may be lost.

If you are using catalog RLS support and decide to no longer use it, the AMS SHCDS CFRESET command is used to reset applicable RLS indicators in the catalog. See z/OS DFSMS Access Method Services Commands for more information about the SHCDS command.
