You probably need to talk to you data storage group - they might be able to do this in the SMS ACS routines (e.g. If first node for alloc of new dataset is a TSO id, check total space used and reject request is > 5Mb). I'm not an ACS expert myself so I don't know if this is pratical or not. If it is, it would slow down allocations a bit.

However, I don't think storage limiting is usually done like this; more typically groups of users would be allocated a pool of storage (storage group) between them to share.

Another approach would be a more flexible one which would allow them to temporarily exceed the limit would be to run a daily or weekly scheduled job to check their total dataset use. This could send them a warning on the lines of 'Space limit exceeded, if it is exceeded at the next check then the oldest/ biggest/newest/whatever datasets will be deleted'.

But 5mb sounds a bit stingy these days - that's only about 7 cylinders of 3390...

The ACS routine could be used reject a single allocation that was greater than a predetermined size. But it is incapable of determining previous allocations.

Unfortunately, all you can do is monitor exceptions after the event with tools like DCOLLECT and MXG.

There are commercial packages which will do this. Sorry I don't know any names offhand.
