Tom,
speaking for consoles: For at least the past 25 years the 'reasonable' standard
has been just what the health check tells you:
- Do NOT send all routing codes or all routing codes except 11 (programmer
information) to either the consoles or the hardcopy log.
- Do NOT configure the MSCOPE for messages so that they automatically get sent
to another system. This is a performance issue.
I believe that that is even documented.
I have my consoles set up like this (we don't have MCS consoles anymore):
DEFAULT ROUTCODE(1-10,12-128) HOLDMODE(YES)
CONSOLE DEVNUM(SYSCONS) ROUTCODE(1-10,12-128) INTIDS(Y) LEVEL(ALL)
UNKNIDS(Y)
CONSOLE DEVNUM(HMCS) NAME(HMCS&SYSNAME.) AUTH(MASTER) MSCOPE(*)
INTIDS(Y) LEVEL(ALL) UNKNIDS(Y) ROUTCODE(1-10,12-128)
PFKTAB(PFKTAB1) TIMEOUT(10)
Both SYSCONS and HMCS are represented as EMCS consoles in the system. Both
definitions violate the rule 'all routcodes except 11'. That may be the reason
I deleted the health check. (Since I did the delete when we still had MCS
consoles, I may need to revisit that deletion). As far as I am concerned,
syscons and HMCS are only seldom active and I need to see what's going on and
cannot limit the route codes to (1-10,12-16) for these two consoles.
In another shop we had one product that *required* MSCOPE *ALL. We identified
the messages that were needed there, gave them a certain routing code and set
the product console (admittedly an MCS console) to only receive that routing
code. That console then got MSCOPE(sys1,sys2,sys3,sys4). At the time, that
seemed to satisfy the check (IIRC).
As far as I know, z/OSMF communicates via EMCS consoles. For EMCS consoles, you
can set attributes via RACF parm. Unfortunately, when the product defines and
activates the EMCS console, it can overwrite what you had RACF-defined. We
don't run z/OSMF (yet), so I cannot check for myself, but I am guessing that
z/OSMF has either MSCOPE *ALL or all routing codes or both hardcoded. If that
is the case, then you should open a PMR with IBM and ask them why z/OSMF
violates best practises.
If you delete the health check (as I did), just make sure that all your MCS
defaults are 'reasonable' as stated above and that you don't have other
products that set EMCS consoles with ROUT(ALL) and MSCOPE(*ALL). And remember
that these two settings are really really bad for performance, as all messages
need to get sent via XCF to all the systems.
Having said all that, which consoles are shown when you do the requested
commands:
DISPLAY CONSOLES,L,FULL
DISPLAY EMCS,FULL,STATUS=L
Are they all z/OSMF consoles? Or are there several products involved?
Best regards, Barbara
