Migrating to IBM WebSphere MQ for AIX Version 7.0 - Middleware News


If you want to migrate to WebSphere MQ Version 7.0, complete this task.
If you migrate from a previous level of this product without first backing up your system, you cannotrevert to your previous level, so back up your system before you install WebSphere MQ Version 7.0. You can then back out the upgrade if necessary. If you back out the upgrade, however, you cannot recover any work, such as changes to messages and objects, performed by WebSphere MQ Version 7.0.

Procedure

  1. Stop all MQ applications on the machine and the applications accessing remote machines.
  2. End all WebSphere MQ activity.
    1. Log in as a user in group mqm.
    2. Use the dspmq command to display the state of all the queue managers on the system.
    3. Use the endmqm command to stop all running queue managers.
    4. Stop any listeners associated with the queue managers, using the command:
      endmqlsr -m QMgrName
    5. To check that you have stopped all of them, enter the following:
      ps -ef | grep mq
      Check that there are no processes listed that are running command lines beginning amq orrunmq. Ignore any that start with amqi.
  3. Log in as root.
  4. Function supplied by the SupportPacs in Table 1 has been superseded by function in WebSphere MQ Version 7.0. Remove these SupportPacs before installing WebSphere MQ Version 7.0.
    Table 1. SupportPacs superseded by WebSphere MQ Version 7.0
    SupportPac NumberDescription
    MA0YWebSphere MQ Bridge for HTTP
    Note: If you installed SupportPac MACS, remove the directory /usr/mqm/inc64 and its contents.
    Review any other installed SupportPacs for their applicability to WebSphere MQ Version 7.0.
  5.  If you are migrating from WebSphere MQ Version 5.3 to WebSphere MQ Version 7.0, you must uninstall WebSphere MQ Version 5.3. If you are migrating from WebSphere MQ Version 6.0 to WebSphere MQ Version 7.0, you do not have to uninstall WebSphere MQ because the installation process does it for you. However, when migrating from WebSphere MQ Version 6.0 to WebSphere MQ Version 7.0, before installing you must ensure that you manually remove the file sets which have been retired from WebSphere MQ Version 7.0.
    • Remove the following file sets before migrating from WebSphere MQ Version 6.0 to WebSphere MQ Version 7.0:
      • mqm.msg.De_DE
      • mqm.msg.Es_ES
      • mqm.msg.Fr_FR
      • mqm.msg.It_IT
  6. Install WebSphere MQ Version 7.0 by following the tasks set out in Installing a WebSphere MQ server.
  7. Restart WebSphere MQ.
