Re: Question on SERVICE EXEC and PUT2PROD

Thanks, Alan. I see a need for an RCF except for the fact that the most 
complete documentation is in the GROUP help screens and not in any document. 
After I get out of my meetings today, I'll submit one if I have the time. If 
not today, then tomorrow.

OK.   So I can run both and be OK.

Thing is we're going from RSU 0702 to 0901. 

Someone told me the update can affect TCPIP and that sessions could be

That is correct.  There is no recovery id.  When each user IPLs the 
single-user GCS, they are not joined into a group.

Just specify it as "*" (like the DUMPVM= default).  But it doesn't really 
matter.  In single-user mode, the recovery and dump machine values are 
overridden at IPL time anyway.

See above.  A single-user mode GCS is automatically RESTRICT=NO, so anyone 
can IPL it.

2009-04-21 Thread Kris Buelens
It is indeed not required to XAUTOLOG a recovery machine if a "single user
GCS", it won't be used, it has no role to play.

Maybe REXX code behind the GROUP panels aren't clever enough.  In fact, what
you enter there is saved into a "fn GROUP" file, but will also be copied in
"fn ASSEMBLE" and that is assembled, yileding "fn TEXT".  Maybe the
Assembler macros are more clever and don't require a recovery userid for
"single user GCS" systems.
I never used the GROUP panels anymore since VM/SP R6, I used the ASSEMBLE
file, what allowed me at that time to make overrides to make GCS variants
depending on the target system. Hence the panels are not fresh in my mind.

Re: Question on SERVICE EXEC and PUT2PROD

2009-04-21 Thread Schuh, Richard
Are you saying that in a single user environment, it is unnecessary to even log 
the specified recovery machine on? If not, is it even necessary to specify a 
real id?
It appears that what is being implied, but not stated in this thread, is:

1. For a single user system, you must specify an arbitrary recovery machine 
userid simply for purposes of having it included in the NSS. (Why can it not be 
blanks in this instance?)
2. That userid does not have to exist because it will never be logged on. (Does 
anything bad happen if it is defined and someone logs it on and IPLs CMS? 
Probably not, but it most likely would be a bad idea for it to be allowed to 
IPL GCS.)

I have, over the years, frequently heard, "Do not infer anything, especially 
when dealing with IBM systems. If it is not explicitly stated in the 
documentation, you cannot assume that it is so." Here, it appears that we must 
trust that our inferences match the intended implications.

I'd say the recovery userid you specify will be ignored.

In fact, in such a "single user GCS" userid you could run RSCS, VTAM, VSCS, and

The GCS recovery machine is mainly meant to be able to cleanup the common

Rather than GROUP=NO, there is an entry for "Single User Environment (YES or 
NO)". Above that line, there is one that asks for "RECOVERY MACHINE USERID 
(required)"

The note dealing with the single user entry reads:


5. Will the GCS system run in a single user environment?

Enter YES to create a single user environment. Specify NO, to create a

group environment with common shared storage.

Applications that do not require group communications and that run

without the use of shared common storage can run in a single system

environment. These applications will run without the overhead of group

initialization and multiple virtual machines. For example, a test

environment requiring a single user and not group communications will

be able to run without the overhead of group initialization and the

multiple virtual machines.



I take that, "the multiple virtual machines," in the last two statements to 
mean other machines like VTAM, ACS and buddies, but does not include the 
recovery machine (which is, per the display, required). The note related to the 
recovery machine question states that the GROUP command does check the recovery 
machine userid for validity, "but does not prevent you from saving an incorrect 
entry." What does that mean? You can put in something that would be acceptable 
as a userid, even though there is no such id in the directory, or it must be an 
existing id, even including one that is NOLOG?

All of that begs the question, how do you accomplish running without the 
recovery machine? Do you simply enter an id and never log it on? I know that in 
multiple user mode, GCS refuses to come up in RSCS or any other machine in the 
group if the recovery machine is not already on. The documentation is perfectly 
clear (to the one who wrote it).

For non-SNA networks, I prefer to run RSCS in single-user (GROUP=NO) mode 
so that there is no recovery machine and it can be treated like a 
stand-alone CMS user.

Updates to the CP nucleus would never require a reIPL in a short time: the
CP nucleus resides in storage, storing a new one on MAINT CF1 doesn't harm
at all.
However, if there are updates to the CMS resident, many CMS users are at
risk after PUT2PROD, you can restart them one by one or by a reIPL.
For GCS, even SERVICE is a bit disruptive: the GCS saves system is replaced,
what means an IPL GCS will fail untill the GCS recovery machine (hence all
other GCS users) are restarted.  Q NSS USERS GCS will reveal which of your
users might be affected.  Without SNA, RSCS is probably the only user.

Right now, I'd like to minimize the downtime for our users.Since we're

Is running SERVICE EXEC distruptive to the running system?   I would think 
PUT2PROD would be.


Can I run SERVICE to apply the service and then at a later time when we 
schedule an outage, I can run PUT2PROD and SHUTDOWN/re-IPL?


Thanks
  
Run SERVICE at any time. When you are ready run PUT2PROD and  re-IPL.  
Unlike some systems  PUT2PROD will not force a re-IPL but you should do 
one soon after it runs if there were updates to the CP NUCLEUS on the RSU.

Neither service or put2prod are disruptive to the guests.
It's the shutdown that will be :)

Subject: [IBMVM] Question on SERVICE EXEC and PUT2PROD

We're about to apply some RSU's to our current 5.3 system.System has

been running great without issues.

Right now, I'd like to minimize the downtime for our users.Since
we're 
running z/Linux with production servers.

Is running SERVICE EXEC distruptive to the running system?   I would
think 
PUT2PROD would be.

Can I run SERVICE to apply the service and then at a later time when we
schedule an outage, I can run PUT2PROD and SHUTDOWN/re-IPL?

Thanks
