Oracle Error ORA-03114: not connected to ORACLE

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.
