Alerts when failover (JDBC Master Slave) occurs

[janne postilista <ja...@gmail.com>]

I can configure ActiveMQ master/slave failover so that when my active
master instance fails, it releases a database lock, then a slave
instance grabs the lock and starts processing messages:
http://activemq.apache.org/jdbc-master-slave.html

Does this feature support alerts when failover happens, for example I
could plug in a class which sends email to an admin when failover
occurs?

afraid not, there is currently no support for a handler when  a lock
is acquired.
However, the default database locker is plugable so you could extend
and provide your own implementation that can alerts when it acquires
the lock.

All contributions are most welcome in this regard.
To peek at the current impl see:
