    Hi,

    I am looking for the experienced person who has recently upgraded MQ to version 9.3.4.0 on Window server.

    I have some questions to ask.  

     

     

    Thank you very much.

    You should post your IBM MQ question in the MQ forum.

    The first thing you should read is the difference between CD and LTS releases of IBM MQ:
    https://www.ibm.com/docs/en/ibm-mq/latest?topic=planning-mq-release-types

    The current IBM MQ CD release is 9.3.4.1 and the current LTS release is 9.3.0.15.  You should always install the latest release of the software.

    In the future, just post your questions. If your question is about what to install, select custom install and pick those components that are required. i.e. Java, GSkit, etc... If you are not using MQ/MFT then don't install it.

    later

    My first question is how to back up the whole existing MQ 8.0.0.5. Including Queue managers, channels definitions and so on so forth.

     

    Current version installation is as the below.

    InstPath:    C:\Program Files\IBM\WebSphere MQ

    DataPath:    C:\ProgramData\IBM\MQ

    FilePath    REG_SZ    C:\Program Files\IBM\WebSphere MQ

     

    Thank you very much.

    For a default install, MQ stores all of the queue manager(s) information in the following directory:

    • For Windows, the directory is:  C:\ProgramData\IBM\MQ\qmgrs\{QMgrName}\ 
    • For Unix/Linux, the directory is:  /var/mqm/qmgrs/{QMgrName}/  

    If you only have 1 queue manager then it's pretty straight-forward. For more than 1 queue manager, you just repeat the following steps for each queue manager.

    Here's what I do before I do a major upgrade for Linux, Unix or Windows.  i.e. 9.2 -> 9.3

    • Log onto the server as an authorized MQ user
    • Run the dmpmqcfg command against each queue manager (it must be running) and dump everything to a file
    • Stop all queue managers on the server (before taking a backup)
    • Go to the "qmgrs" directory. i.e. C:\ProgramData\IBM\MQ\qmgrs\ 
    • For Windows, zip/compress each queue manager directory.  i.e. Queue Manager name of MQA1

    zip -r -o MQA1_backup_20240105.zip MQA1\*.*

    • For Unix/Linux, tar then compress each queue manager directory. i.e. i.e.  Queue Manager name of MQA1

    tar -cvf MQA1_backup_20240105.tar MQA1/*

    zip -r -o MQA1_backup_20240105.tar.zip MQA1_backup_20240105.tar

    Since, you are on a very old release of IBM MQ, you should read the Migration Paths in the MQ Knowledge Center.

    https://www.ibm.com/docs/en/ibm-mq/latest?topic=mq-migration-paths

    From the Knowledge Center, since you are using MQ v8.0.0.5, you can go directly to MQ v9.3.  Make sure you install the latest release of MQ which is 9.3.0.15 for LTS and 9.3.4.1 for CD. Your company is not proactive in keeping up with the latest release of MQ, therefore, I would not install MQ CD release.

    Hope that helps.
