This example builds an alternate index over a previously defined base cluster, EXAMPLE.KSDS2. Data records are already loaded into the base cluster. The alternate index, its path, and its base cluster are all defined in the same catalog, USERCAT.

Job control language statements:

• BASEDD DD describes the base cluster.
• AIXDD DD describes the alternate index.
• IDCUT1 and IDCUT2 DD describe volumes available as sort work data sets if an external sort is done. They are not used by BLDINDEX if enough virtual storage is available for an internal sort. If there are multiple volumes, a maximum of five volumes for each work file can be specified.

The parameters are:

• INFILE names the base cluster. The ddname of the DD statement for this object must be identical to this name.
• OUTFILE names the alternate index. The ddname of the DD statement for this object must be identical to this name.
• CATALOG identifies the user catalog.
