  • 1.  DR RDQM Floating IP?

    Posted Wed February 09, 2022 05:04 PM
    I have been reading about DR RDQM in the IBM MQ 9.2 Documentation and i cannot find a reference to how clients connect to the DR instance should it be made primary.   Is there a Floating IP option or do client use a conname with a host:port list as in the case of a Multi Instance installation.

    What's best practice?

    Hi Thomas,

    The floating IP address feature that can be used with HA RDQM is not available for DR RDQM.

    According to IBM Docs: Switching over to a recovery node, they suggest a conname list.

    Provided that you have defined your channels with a list of alternative connection names, specifying your primary and secondary queue managers, then your applications will automatically connect to the new primary queue manager.

    Of course, you might have a different process for your DR experience, such as changing the hostname's IP address to point to the new primary - i.e. something outside of MQ.

    Cheers,
    Morag

    Thank you Morag.   I am a little embarrassed that I missed that in the docs.

    Have a great day - Cheers
