Wayne,
The second issue
HI,
Where can I find the description of the RDC which set the PAV and MIDAW?
Thanks,

And, you are correct.
The algorithm is wrong.

If so, how to do tell z/OS to "spread the I/O" around? I used
to have SELTAPE=NEXT

SELTAPE has gone the way of the Dodo.
The IEAOPTxx parm was dropped with ESA, IIRC.
It is now the lowest available UCB, just like DASD allocations.
Thank you, SMS!

Q1: I would argue that you are spending expensive CPU and sacrificing
throughput to conserve DASD. As cheap as DASD is these days, perhaps the
business case is to reduce/eliminate the need to do space management,
reclaim that CPU, and generally speed up throughput.
As to Q2: Generally speaking,
John -
It's my understanding that this is how allocation currently works and I
don't know of anything in z/OS 1.6 that changes it. I believe that the
STK allocation code is supposed to do this for tape drives in an STK tape
library and perhaps for non-library drives as well, but I don't think tha
We run DFHSM in two address spaces for this reason DFHSM and DFHSM#. Take
a look at the HOSTMODE=AUX parameter and documentation. I classify the
primary DFHSM in SYSSTC and the auxiliary DFHSM in STCLO to provide a
service level roughly equivalent to production batch. We have not yet
