Karl, If you download DAF (Dataset Audit Facility) from CBTTAPE.org, you will find out exactly what is happenning to your file. Without knowing more about your shop, we would just be speculating.
Looks like the file is initially allocated to an overflow volume which is subsequently cleared of data without regard to source space allocations. End of speculation. ________________________________________ From: Karl Abrahams [EMAIL PROTECTED] Sent: Wednesday, October 15, 2008 6:33 AM To: [email protected] Subject: Space problem Hi Can anyone please help on this one. I have a user who allocates a file with CYL,(100,100)). The file then gets closed and opened 780 odd times and data is added to it with each open. He has tried it with different file names. The SMS DATACLASS and STORAGE CLASS do not allow for space to be released and force the allocation to be one a single volume. Some where during all this space is been release because the step failes with an SB37. The file has changed to CYL,(1,1)) and is in 16 extents. When allowing the file to have multi volume access it works, but changes to CYL,(1,1)) and ends up been in 39 extents. My question is this, is SMS releasing the space or MVS or the program?
