Using IMS managed ACBs for the DB utilities

DB utilities support the use of IMS managed application control blocks (ACBs). To activate this functionality, complete the following steps: 

• Set the BMC global option keyword IMSMACB to YES in DLIGSET0.
  By setting IMSMACB(Y), you make the job step eligible for IMS managed ACB processing by the DB utilities. The default value for IMSMACB keyword in DLIGSET0 is IMSMACB=Y.

• Provide one of the following for the DB utilities to verify that an IMS managed ACB environment exists:
  • IMS Catalog user exit (DFS3CDX0) in the STEPLIB, JOBLIB or linklist library.
  • DFSDFxxx Procedure library member. The desired member suffix for the PROCLIB member can be specified using the keyword PARM=’DFSDF=xxx’ on the job step’s EXEC statement and including a //PROCLIB DD containing the matching parameter member.

• Provide information for the utilities to find the IMS catalog data set high level qualifier by one of the following methods:
  • Provide an MDA member mapping the Catalog bootstrap data set.
  • From the Catalog database definitions in the RECON datasets.

The utilities honor IMS catalog ALIAS names defined using the catalog exit (DFS3CDX) or the DFSDFxxx Proclib member to support IMS environment with multiple catalogs.
