Hi i was trying to set up a HA broker config via Master/Slave according to the following:
http://www.activemq.org/site/clustering.html The fact that there is no automatic fail-back makes using this option *very* difficult to support in a production environment. Specifically, once the cluster has failed over to the secondary broker (which as documented seems to work fine), the cluster cannot be recovered without the downtime required to stop the SECONDARY, copy the datafiles, start the PRIMARY. This makes routine maintenance of the PRIMARY impossible, because as soon as this happens you are not HA without the required downtime & interruption of service required to fail back to the primary. I am not intimataly familiar with the internals of ActiveMQ, but it seems to me that the easiest way to fix this would be some way of allowing the primary to turn into the secondary (and visa-versa) when it comes back online. This alone should be enough to allow the cluster to continue servicing requests. If a the new primary (old secondary) then needs to be taken down (maintenance, failure) it then swaps back to the secondary role. Thoughts? Are there any current JIRA issues i should be tracking WRT this functionality, or should i create a new request? TIA for any help. -- View this message in context: http://www.nabble.com/HA-features-tf2069049.html#a5696101 Sent from the ActiveMQ - User forum at Nabble.com.
