MQ on z/OS
The QM is running at 7.0.1 happily for years.
MQ 7.1 is installed.
MQ Explorer and MO71 now show:
Command Level = 710
Version = 07010000
DISPLAY SYSTEM shows OPMODE COMPAT , 701
OK, I think I am good - My QM is ready to do 7.1 stuff, and we can roll back to 7.0.1, but why does version still show 701? I was able to create a new CHLAUTH rule, so that’s 7.1, so shouldn’t version also show 710?
This link:
http://www-01.ibm.com/support/knowledgecenter/?lang=en#!/SSFKSJ_7.1.0/com.ibm.mq.doc/mi77119_.htm
Says if I want to be able to roll back to 7.0.1 I should be showing OPMODE COMPAT 701. That’s what I show. So far so good.
But this link:
http://www-01.ibm.com/support/knowledgecenter/?lang=en#!/SSFKSJ_7.1.0/com.ibm.mq.doc/mi77118_.htm
Has this confusing statement

"As part of z/OS: Review and modify queue manager customizations from WebSphere MQ version 7.0.1 to WebSphere MQ version 7.1, you must set OPMODE to (COMPAT,710). If you have not set OPMODE, the queue manager does not start.
The (COMPAT,710) setting does two things:
i.It checks that you are starting the queue manager that links to the version 7.1 libraries.
ii.It disables the use of new function in version 7.1.
You can revert to running the queue manager with the version 7.0.1 libraries, if you have never set OPMODE to (NEWFUNC,710)

???
So if I want to be running as 7.1, but still have the ability to fall back to 7.0.1, what am I supposed to see for OPMODE? What the first link says (COMPAT 701), or what the second link says (COMPAT,710)? Is there a typo in one of these links?

From what you tell us the Version does show V7.1.
Version = 07000100 would be 7.0.1.0
Version = 07010000 would be 7.1.0.0
I'll check on the other question for you......

OK, I guess it does now that I look at the format of the Queue Manager's Version parameter in the MQSC reference for the DISPLAY QMGR command.

VERSION
The version of the WebSphere MQ installation, the queue manager is associated with. The version has the format VVRRMMFF:
VV: Version
RR: Release
MM: Maintenance level
FF: Fix level

But you can see why someone might think that 07010000 is 7.0.1. Now I know, thanks! _________________ Peter Potkay

Yes, this link is telling you what you must ensure your queue manager is displaying, to know that you can go backwards.

You have confirmed this, so you can go backwards.

This page is telling you that you must build your ZPARM module with the version number mentioned matching the version number of the libraries you are currently running with.
This is to ensure that you don't end up in NEWFUNC mode when you didn't mean to! Imagine if you had a ZPARM module that was setup for OPMODE (NEWFUNC, 701), you'd be upset if we assumed that meant you wanted to go to OPMODE (NEWFUNC, 710) straight away. So you have to build your ZPARM deliberately with OPMODE (COMPAT, 710) so we know you want to run in COMPAT mode and you're doing it with the 710 libraries.
The display

is the important part - this shows that you are compatible with (and can go back to) 701.
Clear as mud huh?

Yup.
So, are you saying the 3 digit version number for OPMODE when specified in z/Parm is meant to indicate what version you want the QM to run at, but the 3 digit number for OPMODE in DISPLAY SYSTEM is meant to indicate what version you want to be able to fall back to?
The same parameter means 2 different things depending on whether you are setting it or displaying it?! _________________ Peter Potkay
