Using IMS management of ACBs

IMS Catalog Definition exit routine (DFS3CDX0) is required when IMS HP Change Accumulation Utility references the database definition in an IMS management of ACBs environment.

When IMS management of ACBs is enabled and IMS catalog data sets are not registered in the DBRC, specify the DFSHDBSC data set to the skeletal JCL. Refer to Specifying DFSHDBSC DD.
