Good thought. The SMS and non SMS are both 1 extent. Chip Grantham | Ameritas | Sr. IT Consultant | [email protected] 5900 O Street, Lincoln NE 68510 | p: 402-467-7382 | c: 402-429-3579 | f: 402-325-4030

There is a line in this REXX line in the code which allocates the new ISPF.PROFILE dataset with "SPACE(45 15) TRACK". If the target volume group in the UNIT parameter is SMS managed the allocated size is reduced to 38,15. If it is not SMS managed, this allocated size is 45,15. The SMS Storage class has "reduce % on allocation failure" of 0. (Nothing in data classes modifies allocation size). >>I don't understand how it is getting reduced to 38 from 45. Ideas? >>>>>>>>>>>>>>>>>>>>>>> Have you looked at the dataset extents? The primary allocation can use more than physical extent to satisfy the allocation. If your SMS pools are more fragmented than your non-SMS volume, the allocation might be made across more than 1 physical allocation.
