You'd end up with journaled entries not in the store. On Oct 27, 2010, at 8:00 PM, kseelam wrote: > > Thanks for reply. > > Is it possible if we use different (its own) Journal on each Server > (master/slave servers) and use the common DB? > > Thanks > > -- > View this message in context:

Thanks for reply. Is it possible if we use different (its own) Journal on each Server (master/slave servers) and use the common DB? Thanks -- View this message in context: http://activemq.2283324.n4.nabble.com/JDBC-Master-Slave-approach-with-Journal-for-HA-tp3014521p3016538.html Sent from

Thanks lot for your reply Rob. So the Journal can't be used in Cluster environment for HA. Is it correct? Also as per the Journal config defined in http://activemq.apache.org/persistence.html ; Can't we use this configuration on each server (by h

what it needs is a test case, there was one attached to https://issues.apache.org/activemq/browse/AMQ-2596, maybe that can help validate. thanks for the heads up. On 27 October 2010 14:14, chris wrote: > Hi, > > I noticed that in 5.3.2 the removal of a consumer in a network of > brokers sometimes

contradictory patch of ConduitBridge for removing of subscriptions

2010-10-27 Thread chris
Hi, I noticed that in 5.3.2 the removal of a consumer in a network of brokers sometimes triggers the removal of the network bridged subscription even though there are still some other running consumers. The problem was resolved in 5.4 with revision 949742 to handle AMQ-2754. But looking at the cod

Thanks for the reply. TibcoEMS does feel a bit "heavy" for our need wrt licensing and "freedom of deployment". With that I mean that there will probably be lots of different deployments that are built and then torn down often so it won't be very stable environment. Here I like the broker-peering a

I am a fan of AMQ. However, I am not sure that the performance of AMQ is good enough yet for some production systems. So I tend to use AMQ during development and a proprietary offering for production. This also helps deal with the fear that some mgmt have over using open source software (deep s

You shouldn't use the high performance journal with JDBC Master/Slave - http://activemq.apache.org/jdbc-master-slave.html with the journal and JDBC database - messages are stored in the journal - and only the references to those messages are stored in the journal - which would be local to the ma
