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.

When the single address space job processing method (AS1) is used, you can specify the DFSHDBSC data set to the IMS HP Change Accumulation Utility execution JCL (EXEC PGM=HPCADRIV). In this case, you do not need to modify the skeletal JCL.
