Thank you for your reply, Torsten. I checked the logs and all three AMQs were, indeed, coming up as masters. The first one made the lock file, and the other two either didn't see it or ignored it. The shared directory was simply a directory on a fourth Windows server, that was shared out and pointed at, by the other three. Apparently that doesn't support the locking correctly.
I've now been asked to set it up in a JDBC Master Slave configuration, pointing at an Oracle database. I see that configuring the activemq-jdbc.xml file is easy and straightforward to do. What I don't see documented, is how to put it into effect. To setup Shared Directory Master Slave, I edited the persistenceAdapter found in activemq.xml. How do I tell AMQ that it should be using the persistenceAdapter defined in activemq-jdbc.xml - simply comment out the persistenceAdapter in activemq.xml? Again, thanks, in advance, for your time. -ste This message is for the designated recipient only and may contain privileged, proprietary, or otherwise private information.
