Pure master slave recovery questions

If I have a pure master-slave configuration and the master fails, the recovery is to: - shut down the master (if it's not already dead) - shut down the slave - copy "the contents of the data directory" from the slave to the master - start up the master Question 1: In the data directory, there ar

Re: Pure master/slave duplicates delayed messages

Actually, now I'm wondering if I've got the network of brokers toplogy configured wrong too. On mq01.b, I have 25 consumers subscribed to a single queue; looking in the web console on mq01.b, I see the 25 consumers counted against that queue. But looking in the web console on mq01.a, I see 50 cons

Re: Broker Networks and duplicate message delivery

RE: Web Console Availability and master-slave brokers with shared file system

Thanks for your reply, however it seems that this does not do the trick. It seems that the second broker blocks its jetty server from starting up while waiting for acquiring the lock on the shared file system. -- View this message in context: http://activemq.2283324.n4.nabble.com/Web-Console-

Re: Obtaining URLs of ActiveMQ instances

To answer my own question, just checked in code, found org.apache.activemq.util.URISupport utility class (being used by org.apache.activemq.ActiveMQConnectionFactory) which suits my needs. Regards, Stevo. On Mon, Dec 19, 2011 at 2:00 PM, Stevo Slavić wrote: > Hello ActiveMQ community, > > Is th

Obtaining URLs of ActiveMQ instances

Hello ActiveMQ community, Is there an API in ActiveMQ that can be reused to parse broker URL string and determine URL of each broker? I have clients (producers and consumers) configured to access two master/slave brokers using failover protocol via a property, but would like to get urls of each o

Compatibility of jdbc store between amq 5.2 and amq 5.5

Hi, The broker v5.2 of which store is based on oracle has worked for several months. For some reasons I want to upgrade it to the new version 5.5.1. Are there any compatibility issues or some migration instructions I should follow if upgrading?
