Greetings, What problem are you trying to solve? When many of these jobs are running, do you run low on real or virtual storage? Does paging become unacceptable? Is this affecting SLAs? z/OS was built to handle this type of thing. The main issue that I see is the initial load of each 80MB module into user storage; once that is done, the system will trim the working set and you will basically only have in real storage what pages you have recently accessed. Is this vendor supplied code? If so, what are their recommendations? If you end up putting it in common storage, there are audit concerns and change control issues. Cheers...
