z/OS V1R6.0 DFSMS Access Method Services for Catalogs

DELETECLUSTERspecifies that the object to be deleted is a cluster, its associated data andindex entries, and any related paths and alternate indexes.When deleting a VVDS, entryname must be the restricted name'SYS1.VVDS.Vvolser'.Exception: If RLS recovery is associated with the sphere, all knowledge ofthe recovery is lost as part of the delete operation.Abbreviation: CLGENERATIONDATAGROUPspecifies that the entry to be deleted is a generation data group (GDG)entry. To delete a generation data group that is not empty, you mustspecify either the FORCE or the RECOVERY parameter. When FORCE isused, all SMS managed generation data sets pointed to by the GDG baseare scratched. Generation data sets are also removed from the catalogwhen you use FORCE.For both SMS-managed and non-SMS-managed GDGs, if you useRECOVERY, the GDG entry is deleted from the catalog and generationdata sets remain unaffected in the VTOC. To delete a GDG usingRECOVERY or FORCE, you must specify bothGENERATIONDATAGROUP and RECOVERY orGENERATIONDATAGROUP and FORCE.The FORCE and RECOVERY generation data set parameters require RACFFACILITY class authorization. For information concerning RACFauthorization levels, see Appendix A, “Security Authorization Levels,” onpage 351.Abbreviation: GDGLIBRARYENTRYspecifies that the entry to be deleted is a tape library entry. You mustspecify the FORCE parameter to delete a tape library entry that is notempty. A tape library entry is not empty when tape volume entries are stillassociated with it.To delete a tape library entry, you must have authorization to RACFFACILITY class profile STGADMIN.IGG.LIBRARY.Because access method services cannot change the library managerinventory in an automated tape library, ISMF should be used for normaltape library delete functions. The access method services DELETELIBRARYENTRY command should be used only to recover from volumecatalog errors.Abbreviation: LIBENTRYor LIBENTNONVSAMspecifies that the entry to be deleted is a cataloged non-VSAM data setentry or object entry.If the non-VSAM data set has aliases, all of its alias entries are deletedwhen you use the DELETE command.If the non-VSAM data set is partitioned, you can delete one of its membersby specifying pdsname(membername).Chapter 20.
