Mark Gellings commented on AMQ-2498:
------------------------------------
I have handled this problem using a connection pooler. Master goes down, slave
attempts to connect to database and retries however many times configured...
New slave then needs to be started up manually (or automatically through some
automation).

> Reporter: Partha
> Priority: Critical
> Attachments: server.log

>
> When I database is idle for too long or I manually restart database, broker

> I am setting validationQuery and testOnBorrow to true in broker-config.xml
> datasource bean.
> Do I need to do anything else to tell broker for keep trying for database
> connection?
