MQ migration from 920 to 921 with -Uvh : missing elements

  • 1.  MQ migration from 920 to 921 with -Uvh : missing elements

    Posted 28 days ago
    I have a Centos 8 installation with MQ 920 running correctly, with MQ Console configured.
    I decided to upgrade to 921 via rpm -Uvh MQSeries*.

    The migration went well for the MQServer part.

    If I test "dspmqweb", I get the error "AMQ8599E: The dspmqweb command was unable to locate a JRE."
    Actually in /opt/mqm/java/jre64, there is just mq_jre64.tar.gz.
    After a tar -xvf mq_jre64.tar.gz, dspmqweb shows me: MQWB1111E: Program 'server' cannot be located (AMQ6190).

    In /opt/mqm/web there is only tar -xvf mq_wlp.tar.gz.
    After tar -xvf mq_wlp.tar.gz, dspmqweb displays ""
    MQWB1110E: Permission denied when attempting to run program 'server' (AMQ5020)"

    I have the impression that the post-installation tasks did not go well.

    I have uninstalled and re-installed MQ 921 and everything is OK.

    Did I miss something in the migration?

    After re-installing MQ 921 in the usual way, I tried to upgrade to MQ 922 with yum.
    The KC documentation is incomplete, but I managed to do it :
    - strmqm: OK
    - strmqweb: KO
    AMQ6190E: Program '/opt/mqm/web/bin/server' not found.

    The /opt/mqm/web directory is empty, but contains mq_wlp.tar.gz (same problem as for 920 -> 921 via rpm -Uvh)

    For information :
    dspmqver

    I will uninstall and reinstall in the usual way to continue my tests in MQ 922.

    Hi Luc-Michel, thanks for the detailed background. You're correct that this is an issue with the post-installation scripts when the 9.2.1/9.2.2 rpm packages are applied as an upgrade.

    The issue is being tracked under APAR IT36774, and the fix will be delivered in a future CD release. The APAR is still open at the moment while work is ongoing on the fix. When it closes, the following link will become live with the details:
