Hello,
In our current environment we had MQ 7.5.0.5 and WMB 8.0.0.6. We installed MQ 8.0.0.4 on top of that. Even though environment script is setup correctly to use Java under WMB v8 directory, mqsilist list is complaining about Java version mismatch error. Do we need to see any specific environment variable which got updated, as part of MQ v8 installation? If we un install MQ v8, the error goes away.

I do not think I have got enough idea about what to do.
I tried setmqenv command to select one of MQ installation instead of the new MQ v8, but I am un successful. I tried with crtmqenv as well. I will try to execute the command correctly.
| Code: |
tghosh@xxxxxxxxxx [/opt/esb/mqmesb/usr/mqm/bin]> setmqenv -s
AMQ8595: The setmqenv command was not preceded by the source command.
tghosh@xxxxxxxxxx [/opt/esb/mqmesb/usr/mqm/bin]> setmqenv -n Installation2
AMQ8595: The setmqenv command was not preceded by the source command.
tghosh@xxxxxxxxxx [/opt/esb/mqmesb/usr/mqm/bin]>
|
Then I tried . setmqenv -n Installation2 which seems to be successful, but still mqsilist is failing. |

There is more to it with using MQ8. MQ8 mandates a minimum java version of 7.0 IIRC. So your default WMB is still at Java6. You need to ask IBM for the Java upgrade to WMB and verify compatibility between the WMB version and the MQ Version.
Have fun

You need to source/apply/run mqsiprofile in order to run mqsilist.
If you have created your broker against a v8 queue manager, you may also need to source (which you did with ". ", but you could have also done with "source ") setmqenv.

I am sorry for replying late...
Please see below that I have used setmqenv command without any error to select MQ 7.5.0.5 installation 1. Definitely I have sourced mqsiprofile for WMB v8, still mqsilist fails and this happens after installing MQv8.
| Code: |
tghosh@xxxxxxxx [/u/tghosh]> . /opt/esb/mqmice/usr/mqm/bin/setmqenv -n Installation1
tghosh@xxxxxxxx [/u/tghosh]> . /opt/esb/mqsi/8.0/bin/mqsiprofile
MQSI_JSON_NUMBER_PRECISION_TYPE=DECIMAL
MQSI 8.0.0.6
/opt/esb/mqsi/8.0
tghosh@xxxxxxxx [/u/tghosh]> mqsilist
BIP8075E: A Java exception was caught from class 'com/ibm/broker/config/util/MQSIList.main'. The text is 'java.lang.UnsupportedClassVersionError: JVMCFRE003 bad major version; class=com/ibm/mq/MQException, offset=6'.

Then I did the following, but I believe the result is incorrect because its not showing the ibm integration nodes.. or if mqsilist should not show iib nodes ?
| Code: |
tghosh@xxxxxxxx [/u/tghosh]> . /opt/esb/mqm8/usr/mqm/bin/setmqenv -n Installation3
tghosh@xxxxxxxx [/u/tghosh]> . /opt/esb/mqsi/10.0/iib-10.0.0.5/server/bin/mqsiprofile
MQSI 10.0.0.5
/opt/esb/mqsi/10.0/iib-10.0.0.5/server
tghosh@xxxxxxxx [/u/tghosh]> mqsilist
BIP1281I: No integration nodes have been defined on this machine.
BIP8071I: Successful command completion.

Hello fjb,
All we wanted to run our two version systems parallel.
MQ 7.5.0.5 with WMB 8.0.0.6 and MQ 8.0.0.4 with IIB 10.0.0.5
We don't want / need MQv8 with WMBv8, though I checked that WB v8 is compatible with Java 1.7 well and that might require 8.0.0.7. I / we would e more interested to get working as it is used to be. |

You need to look at mqsiprofile and source the mqenvironment from withing mqsiprofile.
Look at how to create the broker runtime environment. See /var/mqsi/common/profiles and such...
You should have a program there that queries the version of the broker and decide which version of mq to source as a consequence.
Have fun
