More fun with XA STORAGE POOL 255

I changed the size of XA STORAGE POOL 255 from 5100 to I0000 in our
PROD CV and that made all the SOS I was seeing in the CV messages go
away but I still get the GETSTG messages. (note that none of the SOS
counters ever showed anything other than 0)

I went ahead and defined an XA PROGRAM POOL on our test CV to see if the
DMCL would get loaded there and it did BUT it is still in the MEM MAP at
a second address???? All of the DMCL buffers are defined as OPSYS
STORAGE. So the buffer pools should NOT reside within IDMS unless there
isn't enough OPSYS STORAGE.

queue twilight zone music....

Maybe this new extra XA STORAGE POOL that Chris is referring to exists
in Rel 15.0? I did a display mem at both B9FE000 and C3FB388 and there
is the DMCL and DM58 control block. Anyone see anything like this on
their systems?

just a reminder ....

in release 17 - the DMCL always gets loaded into a ""dynamc"" 2nd pool
255
- separate and apart from the ""sysgenned"" 1st pool 255 - this ""dynamic""
2nd poll 255 will always be the size of the DMCL (no bigger, no smaller)
and will appear to all commands to be 100% full (so yes, 2 pool 255s
will
show)

Thanks to those who responded.

We are running Release 15.0

I think Bill Allen hit the nail on the head in his off list email. We
don't have an XA PROGRAM POOL defined (I have no idea why not) which is
where it sounds like the DMCL is supposed to reside.
We do have an XA REENTRANT PROGRAM POOL.

Anyway, I bumped the size of XA STROAGE POOL 255 from 5100 to 10000. The
first 2 GETSTG's were asking for about 5100k and if the DMCL is in
there, it 's full at startup.

More will be revealed. And I'll let you guys know.

Thanks
