Failover</H2>
+
+<P>If you have a SAN or shared file system it can be used to provide <EM>high
availability</EM> such that if a broker is killed, another broker can take over
immediately.</P>
+
+<P>Basically you can run as many brokers as you wish from the same shared file
system directory. The first broker to grab the exclusive lock on the file is
the master broker. If that broker dies and releases the lock then another
broker takes over. The slave brokers sit in a loop trying to grab the lock from
the master broker.</P>
+
+<P>Note that the requirements of this failover system are a distributed file
system like a SAN for which exclusive file locks work reliably. If you do not
have such a thing available then consider using <A href="masterslave.html"
title="MasterSlave">MasterSlave</A> instead which implements something similar
but working on commodity hardware using local file systems which ActiveMQ does
the replication.</P></DIV>
