Subject Re: Running ActiveMQ and having a database failover
Date Wed, 14 Apr 2010 15:31:13 GMT

That's a neat idea, but unfortunately for us it does not appear that
Postgresql supports a failover parameter in the connection URL. 
Additionally, even if it did, it would depend on how it handled the failover
so as to not cause ActiveMQ to puke.

We use a floating IP address to point to the "primary" database server and
use HA to failover to the "secondary" (by simply changing to where the
floating IP address points) if the primary becomes unresponsive.

I'm willing to bet that the problem here is that ActiveMQ uses an open
transaction to "lock" the table or tables necessary to prevent a failover
ActiveMQ server from taking over.

If anyone else as any ideas/thoughts/solutions I would appreciate it. 
Thanks.
