DFSDF control statement

The DFSDF control statement specifies the suffix of the DFSDFxxx member in the IMS.PROCLIB data set. The member with this suffix must exist in a data set specified in the PROCLIB DD statement. If the member contains the ACBMGMT=CATALOG parameter in the <CATALOG> section, IMS managed ACBs is enabled.

This control statement is required only when IMS Index Builder uses IMS managed ACBs through the DFSDFxxx member. This DD statement is not required if IMS Index Builder refers to DBD libraries or if you enable the IMS management of ACBs with the IMS Catalog Definition exit routine (DFS3CDX0).
