Connection validation is now default ------------------------------------ Key: WFLY-5570 URL: https://issues.jboss.org/browse/WFLY-5570 Project: WildFly Issue Type: Bug Components: JCA Affects Versions: 10.0.0.CR3 Reporter: Ståle Pedersen Assignee: Stefano Maestri Priority: Blocker In previous version the validation of connections was either off or set to be run in the background. In WF10RC2 connections are validated when they are fetched from the pool, the connection is validated before it is leased. This cause a huge contention on moderate to heavy db load and should not be the default behaviour.
