Creating and initializing sequential metadata catalogs

The sequential metadata catalog is initialized as part of the installation customization process.

Before you begin

Important: The zFS format of the metadata catalog is the default. This format is the recommended configuration for the metadata catalog that provides significant performance and capacity capabilities in comparison to the sequential data set format.

To grant ownership privileges for the catalog, ensure that each TSO user ID is assigned a unique OMVS UID. Set an automatically generated UID for the user IDs that you are using in RACF: 
ALTUSER USER01 OMVS(NOUID)
ALTUSER USER01 OMVS(AUTOUID)

Procedure

  • Follow the installation customization process.
    The CDCCATNM member in the SCACSAMP data set is customized. The sequential metadata catalog is initialized as part of the installation customization process.
  • Optional: To initialize additional catalogs as needed, customize and run JCL member CDCCATNM.
    Member CDCCATNM in the SCACSAMP data set contains JCL to run CACCATUT with the INIT option. The INIT operation of the catalog initialization and maintenance utility (CACCATUT) initializes data sets for a version 11.3 sequential metadata catalog and creates the SYSIBM and SYSCAC system tables that make up the metadata catalog.
    1. Provide a job card that is valid for your site.
    2. Change the value of the CAC parameter to your own high level qualifier.
    3. Change the value of the DISKU parameter to a valid DASD unit type for your site.
    4. Change the value of the DISKVOL parameter to identify the volume where you want the system catalog located.

Results

When the catalog initializes, it grants SYSADM privileges to the user ID that creates the catalog automatically.
