What exactly does test-connection-in-pool do?

Solution Verified - Updated -

Issue

  • Can you tell me the exact mechanism of the "Test Connection" (test-connection-in-pool) function for a JBoss EAP 6.2.0 data source?

  • The users are trying to troubleshoot connection problems, and they need to know if it just executes a ping method in the JDBC driver and back to JBoss, or makes an actual connection to the database schema, etc.

Environment

  • Red Hat JBoss Enterprise Application Platform (EAP)
    • 6.x
