DEFINE USERCATALOGHint: If a small maximum RECORDSIZE is specified, extensions records for largeGeneration Data Groups (GDGs) must be created.

Itsparameters are:vvvvvvvvvvvvNAME names the user catalog, USERCAT4.CYLINDERS specifies that 3 cylinders are to be allocated for the catalog. Whenthe catalog is extended, it is in increments of 2 cylinders.VOLUME specifies that the user catalog is to reside on volume VSER01.ICFCATALOG specifies that the user catalog is to be in the catalog format.STRNO specifies that up to 3 concurrent requests to this catalog are to beprocessed.FREESPACE specifies the amount of free space to be left in the data component’scontrol intervals (10%) and the control areas (20% of the control intervals in thecontrol area) when data records are loaded into the user catalog.SHAREOPTIONS specifies the extent of cross-region sharing 3 (fully shared byany number of users) and cross-system sharing 4 (fully shared) to be allowed forthe user catalog.RECORDSIZE specifies that the user catalog’s records are variable length, withan average size of 4086 bytes and a maximum size of 4086 bytes.DATA and INDEX specify that parameters, BUFND andCONTROLINTERVALSIZE, and BUFNI and CONTROLINTERVALSIZE, are tobe specified for the data and index components, respectively.BUFND specifies that 4 data buffers, of the data component’s control intervalsize, are to be used when processing this user catalog.CONTROLINTERVALSIZE specifies the data and index component’s controlinterval size, 4096 for the data component, and 2048 for the index component.BUFNI specifies that 4 index buffers, of the index component’s control intervalsize, are to be used when processing this user catalog.214 z/OS V1R6.0 DFSMS Access Method Services for Catalogs
