Parallel processing

The Image Copy function can process more than one database data sets in parallel. Processing tasks in parallel decreases elapsed processing time.

Parallel processing is supported for the following processes:

• Batch image copy process
• Concurrent image copy process
• Group process of batch image copy or concurrent image copy

You can choose either sequential processing or parallel processing for each process. Parallel processing and sequential processing can coexist in one job step.

To apply parallel processing, you use the AIC or the ACIC statement, or the FUNC=AIC or the FUNC=ACIC in the GROUP statement.

You can control the number of parallel processes by using the TASKCTL keyword or the GRPLIM keyword.
