Re: Max Allocation w/ Space= DD
This assumes that space constraint relief is NOT specified in the DATACLAS being used. By specifying a primary extent of 4,000 cylinders, you have essentially eliminated the (12) 3390 mod-3 volumes from consideration, since none of these volumes can satisfy this request. (At most, you will have 3,300 cylinders available on each of these volumes.) This leaves the (2) 3390 mod-9 volumes for consideration. With a limit of 65,535 tracks per volumes for a standard sequential dataset, you have limited the size of your dataset to 8,000 cylinders (1 primary allocation of 4,000 cylinders by 2 candidate volumes ... no secondaries). By specifying (CYL,(2000,1000)), you can get (maybe ... depending on other usage of the volumes) one (1) primary and one (1) seconday extent on each 3390 mod-3 volume, and one (1) primary and eight (8) seconday extents on a 3390 mod-9 volume. Assuming that your data class allows for all fourteen (14) volumes to be used, your max dataset size here is 44,000 cylinders! Note that each extent taken must reside entirely on one (1) volume before proceeding to another. Hopefully, this clarifies the situation. -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html

In fact, my first guess was 64k track limit, but 4000 CYL is 6 tracks. That's less than 64k. Check the OP.

ok. Maybe we're onto something. Could that be why the primary allocation is being reduced to 1 cyl, when the job fails.

However sometimes program closes file and then reopens it again. In such case RLSE shouldn't be used. IMHO you should use use extended format PS, considering compression (SMF data tend to compress quite well). In such case you won't met 64k tracks limit and have 123-extent limit.
