Io Error: Connection Timed Out
am trying to research this issue on the following two errors connecting to Oracle DBs: Closed Connection java.sql.SQException: Io exception: Socket read timed out My understanding: Closed Connection : Is occurring either because there was some sort of network disruption or the DB closed the session due to some sort "inactivity" java.sql.SQException: Io exception: Socket read timed out : This is a case where the connection was made successfully but for some io error socket read timed out vendor code 17002 reason the socket/data was empty and eventually it timed-out because no data was available.
