Hello everybody,
I am looking for a solution that is caused by Information Design Tool (IDT). it seems that the universe can't connect to the database after the migartion from BI4.0 to BI4.0.
I get the following error:
Database error: [Data Federator Driver] [Server] [Connector 'XXXXX'] The database has reported an Exception: ORA-03135: connection lost contact
Process ID: 0
Session ID: 215 Serial number: 3238
(SQLState: N/A, Vendor code: 3,135). (IES 10901) (WIS 10901)
What is the reason for the problem?
Thanks,
Hicham
