Sam,
I wouldn't hold out much hope with the SA/390 version. It still burns a
large amount of CPU at startup. From what I've seen this is due to the
size of the IO config i.e. how big the IODF is. I get the impression
that ESCM reads the IODF and builds a various internal tables and cross
matches them to available IO resources (ie paths). I'm not sure why it
takes so long & so much CPU, maybe inefficient sorting/lookup etc.. but
it could also be due to the way DEVICE objects are stored in the IODF
and how they connect to OS configs. I think there is one record per
device per OS config. This changes with z/OS 1.5 when the IODF is
upgraed to R5 format, so maybe ESCM will get better at startup.. here's
hoping!
As for the licence issues, I know of one site in the UK that has done
this, but don't have the details of exactly how it was done, I think it
was just via their local IBM person.
Out of curiosity, what do you use ESCM for? is it just for managing
simple stuff like names and status of ports on directors?
Regards
Roy

Hi,
We are still running the old Escon Manager (ESCM) on z/OS R6. It works
but it's cranky looping for 40 minutes at startup burning a CP and
throwing out a bunch of GETMAIN FAILED errors but it works.

We had been told the only recourse was to buy a full license for SA/390
but that is not inexpensive and we are already heavily invested and
happy with CA-OPSMVS. I found an APAR II11547 that suggests some
customers have been given an accommodation perhaps as an entitlement,
special bid, or something to get just the I/O Operations piece of
SA/390.

HELP ON HOW TO GET SA OS/390 V1R3 I/O-OPS FUNCTION
ONLY INSTALLED
Is it possible? Anyone gone down this road and care to share here or
off-list some clues we can feed to our IBM team to help them find the
right form to fill out?
