    Network brokers and versions.

    Peter Chandler Master

      When networking/clustering brokers, what are the rules on versions? Do both/all ActiveMQ brokers have to be the same version in a cluster?

          Not necessarily as the openwire protocol used between brokers is subject to versioning. The caveats are for resolved issues or improvements that require some additional features only found in a later release. With a version mismatch, these sort of features will not be available to you. You need to validate using a test to be sure. From a usability point of view, it is simpler to confine networks to a single version.

           

          I address  openwire versioning in a blog post  just last week, hopefully that will explain the issues in detail, the remarks about client to broker communications are equally applicable to peer networks.
