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

Order of Catalog UseFor a target VOLCAT that is SPECIFIC (not VGENERAL), you must specify theVOLUMEENTRIES parameter. You do not want all entries merged into a specificcatalog.If the case is VGENERAL to SPECIFIC, the specified entry characters must matchthe first two third qualifier characters of the target catalog.You may not use the REPRO command to copy the catalogs of two VGENERALs,whether MERGECAT or NONMERGECAT is specified.REPRO NOMERGECATCopies volume catalogs. When you copy a volume catalog to another volumecatalog, REPRO verifies that the target is a volume catalog.For additional information on tape volume catalogs, VOLUMEENTRIES, andLIBRARYENTRIES, refer to z/OS DFSMS OAM Planning, Installation, and StorageAdministration Guide for Tape Libraries. Also see z/OS DFSMS: Managing Catalogs.The VOLUMEENTRIES parameter cannot be specified on a NONMERGECAT. Italways copies all entries in the volume catalog and cannot be restricted to a subset.If NOMERGECAT or the default of NOMERGECAT is specified, the first qualifiersof the VOLCATs must not match while their third qualifiers must match. Thisallows users to make a copy of a VOLCAT, but ensures that the copy is of thesame type. You do not want VA entries to be copied into the VB catalog, forexample.Tape Library Naming ConventionsTape LibraryTape Library Names: The 1-to-8 character names of tape libraryentries can include only alphanumerics and the national characters $, @, or #. Thefirst character of the name must be non-numeric and must not be the letter ’V’.Tape Volume Names: Tape volume names have a ’V’ concatenated with a 1-to-6character tape volser. The tape volser can include only uppercase alphabetics A–Zand numerics 0–9.Tape Library Date FormatsFor all tape library parameters that require date entry, the date is in the formYYYY-MM-DD, where:YYYY is 0000–2155MM is 01–12DD is 01–28, 29, 30, or 31Specify a day of 32 for the ‘never expire’ date of 1999-12-32.Exception: For both ALTER VOLUMEENTRY and CREATE VOLUMEENTRYrequests, you can specify an expiration date of 1999-00-00.Enter all dates with leading zeros when appropriate.To select the catalog to be searched or chosen for an entry, use the CATALOGparameter. You can use the CATALOG parameter with several commands such asALTER, BLDINDEX, DEFINE, DELETE, EXPORT, and LISTCAT. If you use an aliasname, the catalog associated with the name is searched or selected.Chapter 1. Using Access Method Services 9
