TM batch environment

IMS TM supports a batch region for running application programs. IMS applications cannot use the ESAF to issue SQL calls in batch. This support is provided by an external subsystem.

You can connect Db2 for z/OS® in an IMS TM batch environment in one of two ways. You can use the SSM parameter on the TM batch-region execution JCL and specify the actual name of the batch program on the MBR parameter. Alternatively, you can code the DDITV02 DD statement on the batch-region execution JCL and specify the name of the Db2 for z/OS module, DSNMTV01, on the MBR parameter.

Valid TM batch region types are DBB, DLI, or UPB. All other region types are not applicable to the TM batch environment.

You specify generated program specification blocks (GPSBs) for a TM batch environment using the PSB parameter in the DBBBATCH and DLIBATCH procedures.

The IEFRDER log DD statement is required in order to enable log synchronization with other external subsystems, such as Db2 for z/OS.
