Considerations about interval processing performance

Repeating the same batch program many times is not the best use of system resources: the more frequent, the less efficient. When you schedule the intervals for repeating a command, consider the following information.

Schedule the commands to wait for the expected result rather than repeating the process over and over. This reduces the number of command runs and make more efficient use of system resources. For example, using the file monitor operations makes the current interval wait either until a file arrives, otherwise the operation times out. This heavily reduces the number of runs scheduled in a day.

Additionally, schedule the processing intervals to terminate the resubmission or restart after the expected data has been returned; this is especially useful when you set the FROM or UNTIL keyword.

By setting the RESTART keyword you use the existing occurrence, which in turn reduces the size of the current plan. This reduces the CPU consumption by any PIF, WAPL or other processes that read the current plan.
