Applying parallelism concepts to linear batch to improve performance

In order to see further improvements in response times and elapsed times, organizations can look at parallel processing, or the simultaneous use of more than one processor to execute a program. However, applying parallelism concepts to VSAM batch can pose a challenge because batch is a traditionally linear process.

In this briefing, you can see the main ways that the concepts of parallelism can be applied to batch. These options include refining batch natively, sharing files between batch and CICS in a single region, and sharing files between batch and CICS in multiple regions. All of these options can reduce the length of the batch window and improve response and execution times. In this briefing, you’ll see the theory behind each, their benefits, and their potential limitations to determine which one could provide the best outcome in your environment.
