Using DELTA List Check and Execute in batch mode

In addition to checking and executing DELTA Lists through the ISPF interface, you can run the Check and Execute functions in batch. Batch execution is helpful when you want to execute a DELTA List during non-peak times and the job can be scheduled to be executed by a job scheduler.

Using the DELTA List Check and Execute functions

Two methods exist for running the Check and Execute functions is batch. The decision to use one versus the other is based on whether you leave your BMCXLINK started task active or not. Your DELTA Lists that implement changes to IMS can be checked and executed in batch mode using one of the following methods:

  • If your BMCXLINK is not active, then you must use the DLP#BEX1 in the DLPCNTL data set.
  • If your BMCXLINK is active, then you must use the DLP#BEX2 in the DLPCNTL data set.

When BMCXLINK is not active, the DLP#BEX1 job serves as a batch BMCXLINK and sends the DELTA List to the specified target IMS control region(s). DLP#BEX1 can run on any MVS system which can communicate with the target IMS systems using XCF.

When BMCXLINK is active, the DLP#BEX2 job serves as a TSO session and sends the DELTA List to the BMCXLINK associated with the target IMS control region(s). DLP#BEX2 can run on any MVS system that can communicate with the target BMCXLINK using VTAM because the communication between DLP#BEX2 and BMCXLINK utilizes VTAM in the same way that the ISPF interface does.
