I just noticed the following in one of your postings. "If I want to subtask multiple sorts (same input file),"
If you are going to run multiple sorts concurrently in the same address space, things can get interesting. NOTE: You may want to confirm what I say with your sort vendor. Sorts like resources, mainly memory. They also think they are the only thing running in the address space, or that whatever else is running will not get more memory once the sort has started. This means that starting multiple sorts can have a very negative impact on the sorts started first. Running multiple sorts will often times get you an 878 type abend, especially if your REGION is not REGION=0M. If all the sorts are similar in size and characteristics, then maybe a simple thing as passing the proper parameters in SORTPARM may do the trick. If you have sorts of different sizes and different characteristics and run them all with a common set of over-rides, then some are getting more than they need and others are probably getting less. This is not as simple as it sounds. To put it in perspective, I have 25 years of experience in trying to get it right. Of course, I am trying to balance anywhere from 1 to 48 concurrent sorts of different types and sizes. You'll get it to run, but getting it to run the best it can is not easy.
