You could also direct his file via the ACS routines to a Data Class with the
following:
CDS Name . . . . . : ACTIVE
Data Class Name . . : VSCOMP
Data Set Name Type . . . . . : EXTENDED
If Extended . . . . . . . . : REQUIRED
Extended Addressability . . : YES
Record Access Bias . . . . : USER
Space Constraint Relief . . . : YES
Reduce Space Up To (%) . . : 50
Dynamic Volume Count . . . : 9
Compaction . . . . . . . . . : YES
This should be done with adequate testing. Extended addressing can provide up
to 50% savings in space allocation and works for both Sequential and VSAM.
And if 1000 compacted cyls aren't enough, you now have a volume count of 9.
Caveat: Make sure only normal APIs are used to access the data.

Thanks David for the info. I will speak to the user and ask him to put a vol
parm.
Thanks.

Willie,
Yes, that is correct, the Primary allocation is restricted to one volume.
Given that you haven't provided a volume count greater than 1 in the applicable
Dataclass and your user has not coded a volume count sub-parameter in the Unit
parameter the allocation is restricted to one volume.

David,
Thanks for the suggestion. For my better understanding, Zos will attempt to
satisfy the primary allocation (5 extents) on the same pack. Correct?
