DEF PAGESPACE(NAME(PAGE.LIH1.COMMON) -
Shmuel, I asked around inside IBM, hence I'm replying about 10 days after
you asked your question. Sorry for the delay.
I don't think any session managers support what you're asking due to a
current VTAM limitation. However, now that IBM has lifted the veil a little
on z/OS 1.12, I can tell you
I have a couple HSM SDSP questions.
First, is it possible to influence the choice of which SDSP data set is
selected for migration? We have eight SDSP data sets defined but the first
available SDSP data set is almost always selected since we only run one
migration task at a time. I would prefer
1) No. You can only accept or reject migration on a dataset basis via
exits.
2) YES and YES. Again, L2 migration can (IIRC) be controlled via the
exits.
HTH,

George, glad be of help. DataDirect is not a party in the IBM lawsuit, in
fact, we are strongly in favor of IBM's specialty engine strategy. We have
been able to achieve almost 100% zIIP eligibility in our Shadow products and

Um, folks, we seems to be mixing apples and Iphones here. In this context,
page files, IODF's, and master catalogs are not really VSAM.
And, yes, the rules for the SYS1 HLQ are a little different.

One place that MAY use it would JES2 for the SPOOL datasets. Since all
spool datasets have the same name, if JES2 had the ENQ on the dataset
name, you would be unable to delete or create additional SPOOL datasets
while JES2 is running.
