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.

Table 1. Destinations for procedural JCL

JCLOUT description:	Custom Procedures (Note 1)	Standard Procedures (Note 2, 3)	Started Task Control (Note 4)	Single Address Space (Note 2, 5)
HPCAPROC DD	YES		YES
A member of a system library in the IEFPDSI concatenation.	YES		YES
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.	YES
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.
