> Improve JDBC connection management
> ----------------------------------
>
> Key: ARTEMIS-2823
> URL: https://issues.apache.org/jira/browse/ARTEMIS-2823
> Project: ActiveMQ Artemis
> Issue Type: Improvement
> Components: Broker
> Reporter: Mikko
> Assignee: Francesco Nigro
> Priority: Major
> Time Spent: 16h 20m
> Remaining Estimate: 0h

> I have a case where the whole clustering reliability and HA must rely on HA
> capabilities of clustered database, and running on top of application server
> is not an option.
> The current JDBC store implementation is rather bare bones on the connection
> management side. JDBC driver is used directly with no management layer. At
> startup, the broker just opens couple of direct connections to database and
> expects them to be available forever. This is something that cannot be
> expected in HA production environment. So, similarly to the discussion linked
> below, in our case we lose the db connection after one hour, and all the
> brokers need to be restared to get new connections:

>
> This is something that could be resolved by simply using JDBC4 isValid
> checks, but proper connection handling and pooling through datasource would
> be preferrable.
> I have implemented a solution for this by using DBCP2 datasource. Our test
> cluster has been successfully running this forked version since the release
> of Artemis 2.13.0. I will prepare of pull request if this is seen to be
> something that can be useful.
