The 6.8
Message Broker that ships has several fixes, making it the only
Message Broker that you will want to use with any release mentioned in this section. Install the 6.8
Message Broker over any older version of the 6.8
Message Broker and upgrade any installation of 6.7
Message Brokers. All
Message Broker versions are interoperable; consequently, you can upgrade them one at a time.
-
Install
Message Broker 6.8 on the same machine as
Message Broker 6.7, letting the installer set it up as an auto-start service.
-
If you have customized the file
STMessageBroker67.ini, copy it to the
Message Broker 6.8 installation folder with the new name (STMessageBroker68.ini) so that you can reuse that file with
Message Broker 6.8.
-
Stop
Message Broker 6.7, and set the corresponding service (MPX Message Broker 6.7) to
Manual so it does not automatically start again.
-
Start
Message Broker 6.8.
-
Determine that everything is working as expected, and then uninstall
Message Broker 6.7. Multiple releases of
Message Broker can run on the same machine if each uses its own port. You cannot start both the 6.7 and 6.8
Message Brokers at the same time if they are on the same machine and listening on the same port. Doing so causes a race condition, and the
second one to start will fail.
