Scheduled Failover
------------------
Key: AMQ-1660
URL: https://issues.apache.org/activemq/browse/AMQ-1660
Project: ActiveMQ
Issue Type: Improvement
Components: Broker
Affects Versions: 5.0.0, 4.1.1
Environment: all platforms that support a running standalone broker
Reporter: Rob Bugh
I am using a JDBC Master/Slave topology. I'm using Postgres as the db and
noticed that due to the long running transaction of the master holding the lock
on the activemq_lock table my vacuums are not cleaning as many dead tuples as
they could. If you are familiar with postgres then you know that vacuum can
only recover dead tuples up to the point of the oldest transaction. My activemq
database is on the same db server as my production db.
So I would like to regularly failover the master to the slave to keep the lock
transaction timestamp moving forward in time.
Is there any facility built into activemq that would allow me to schedule a
restart of a broker? For example, it would be nice to have the ability to
specify in the broker.xml a TTL value that would mean run for this much time
then restart yourself (or shutdown).
