Oracle Error Message
ORA-03114: not connected to ORACLE
Reason for the Error
This might occur as a result of calling Oracle even if there was no connection.
It is as a result of a user-written software not being logged in.
The explanation might potentially be because the client’s connection to the database was terminated without waiting for the client to deliver a request when an ALTER SESSION KILL SESSION or ALTER SYSTEM DISCONNECT SESSION was issued with the IMMEDIATE qualifier.
Solution
Make an effort to connect once more.
Check the software if the same error message keeps appearing and it was user-written.
