Still on z/OS 1.10. 1.12 is in the works, but due to a problem caused by lack of a maintenance contract, we need to be off of a vendor product before we can convert.
Somewhat on topic to this is an "interesting" discovery I made. If you do a logical dump of a multivolume VSAM KSDS using ADRDSSU, and then do a RESTORE from this with an OUTDYNAM((onevol)), ADRDSSU puts out an ADR390I message about UNMATCHED SIZE and attempt to reallocate the dataset with a new SPACE parameter equal to the sum of the size of all the extents. In our case, this was 7400 cylinders. Which cannot fit on a single 3390-3 volume. So we get some SMS messages about space contraint release being invoked. The LISTCAT on the KSDS now shows a primary space of 7400 cylinders instead of the original value. But all seems well. AT THIS TIME. However, if you then do another logical dump of this KSDS, the restore of that second dump __fails__ with an allocation error about not having any volume with sufficient free space (well, duh! No 3390-3 will ever have 7400 cylinders of free space). In this second case, space constraint release is not invoked. Most weird. If you prealloca! te the output file with the original SPACE parameters and remove the OUTDYNAM, then the RESTORE works correctly and, even better, does not change the space allocation parameters. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
