Creating IMS HP Change Accumulation Utility procedures

When the JCL is converted, each IMS/CA step (PGM=DFSUCUM0) becomes a separate procedure for use by IMS HP Change Accumulation Utility.

Procedures are limited to a single process of DFSUCUM0, but any number of other steps created by the DBRC skeletal JCL can be included. Depending on the processing method selected, the procedural JCL is written to one of several destinations, as indicated in the following table.

HPCAPROC DD YES   YES  
A member of a system library

A member of a system library
in the PROC00 concatenation.
 YES      
A user-defined library requiring
no special authority.
     YES  
In extended batch mode, HPCAPROC
can be a temporary data set.
     YES  
 
HPCAJLIB DD YES      
A member of a system library
in the IEFPDSI concatenation.
 YES      
A member of the system library
in the IEFJOBS concatenation.

HPCACTL DD   YES   YES
Encoded for use in dynamic allocation.
   YES   YES

1UPDATE authority is required to access these system procedure libraries.

2Dynamic allocation does not support all possible DD parameters that can be used in JCL. When present, these parameters are ignored.

3The only step converted is IMS/CA, PGM=DFSUCUM0. Other steps in the JCLOUT file are ignored. To include other steps before or after IMS/CA, the additional steps must be defined in the standard procedure JCL member.

4 Update authority is required for the library name in the HPCAPROC DD.

5 The only step allowed is IMS/CA, PGM=DFSUCUM0. Other steps in the JCLOUT file are ignored.
