![]() Deleting VVDS Records and VTOC DSCBs z/OS DFSMS Managing Catalogs SC23-6853-00 |
|
Occasionally, a VVDS might have a record for a data set which no longer exists, or for which there is no corresponding BCS entry. The VVDS contains VVRs for all VSAM data sets and objects, and on SMS-managed volumes, NVRs for non-VSAM data sets. You can use the access method services DELETE command to clean up a VVDS and to remove records for data sets which no longer exist or which have become uncataloged. Specify either VVR or NVR to delete the appropriate type of record. The DELETE command only deletes the VVR or NVR if there is no corresponding entry in a BCS for the data set. When the VVDS record is deleted, the corresponding DSCB in the VTOC is also scratched. If there is no VVDS record for the data set, the DSCB is still scratched. In order to delete a VVR, specify the component name (the "truename") to be deleted, rather than the cluster name. STGADMIN.IGG.DLVVRNVR.NOCAT protects the ability to delete a VVR or NVR without an associated catalog. For more information, see the note on catalog requests under STGADMIN.IGG.DIRCAT in Storage Administration (STGADMIN) Profiles in the FACILITY Class. ![]() ![]() ![]() |
