OCI-03114
not connected to ORACLE
Cause
The connection between the Client and Server process did not exist. This is likely the result of an earlier ORA-03113 error. The cause may be that the database instance experienced a maintenance or unplanned outage, or that the Server process had a fatal error, or that the network connection was interrupted.
Action
Check the alert log of the database instance to see if a planned or unplanned outage occurred. Check the alert log to see if a process termination (ORA-07445, kill, or ORA-00600) occurred. Check for network problems and review the SQL*Net setup. After the problem is identified and resolved, retry the operation.
