That's it, thanks! I was expecting something like: SET SSN=00 or
something like that. Doh.

I've been searching for the answer to this in the docs, but obviously
I'm not looking in the right place (yet).
If I add something to IEFSSNxx do I need to IPL? Or is there a SET or
some other command that will work?
Rega
Lizette,
Great explanation and just enough to keep from confusing me.
Thank you.

The IRLMs are identified by what your DB2 SYS PROG requests and is specific
to your shop standards. So the IRLP or JRLP would be something unique to
your shop and it is possible no one else would use that convention.
You will need to contact the person that installs DB2 at your shop to get a

We are testing 1.7 and getting ready to go. While messing around with DB2
we had an issue with the region coming up until we added IRLx and JRLx
entries in the IEFSSN00 subsystem names. I'm not a DB2 type, nor do I
completely understand all the relationships such as IRLP/JRLP for a production

Taking Ed's estimate of three instructions per inactive SSCVT, and
assuming 10M WTOs per day, and ten inactive subsystems... that's roughly
a CPU second per day spent
l overhead,
calculated as a percentage of the system's capacity, that can be
attributed to maintaining "dummy" subsystems in IEFSSNxx.
Generally, the number of broadcast SSI requests is tiny (relatively
speaking) when compared to the work being executed by a system. For any
single broadcast

those sent to a particular named subsystem - use a hash table lookup.
I'd be surprised if the delay was NOT measurable. But I suspect the delay
is not significant.

in my
opinion, a no-brainer to share one IEFSSNxx across the plex.

SSCTs are tiny. There is almost no storage waste for an unused
subsystem. Performance isn't impacted either because subsystem name
lookup is via hash table.

2)10 production (db2, mq etc)

What is the impact of having a single IEFSSN00 that contains all of the
