When you get this while trying to connect to the database from a DatabaseAdapter, solution as follows

Solution :
Assuming you had already created the datasource & Outbound Connection Pool for the DatabaseAdapter,
Goto deployments --> dbAdapter --> check it & click on 'Update' --> Redeploy.
This should fix the issue. If not, restart and it should fix now.
