Populating the IMS catalog using the IMS Catalog Populate utility (DFS3PU00)

Use the IMS Catalog Populate utility (DFS3PU00) to perform an initial load of an IMS catalog, to update an IMS catalog, or to set up an IMS catalog for the IMS management of ACBs.

The DFS3PU00 utility requires access to the DFSDFxxx member of the IMS.PROCLIB data set. Attributes of the IMS catalog are defined by parameters in the <CATALOG> section of the DFSDFxxx member. Specify the DFSDFxxx member in the utility JCL.

Requirement: The DFS3PU00 utility requires that the section header for the catalog section in the DFSDFxxx member be specified as <CATALOG>. The DFS3PU00 utility does not support the <CATALOGxxxx> heading. The <CATALOGxxxx> heading is used when multiple IMS systems share a DFSDFxxx member, but do not share IMS catalogs.

Note: Do not run the DFS3PU00 utility as a BMP with MANAGEDACBS=SETUP specified when ACBLIBs are used to manage ACBs, which is specified by ACBMGMT=ACBLIB.
