We have a client and server that has been upgraded to Oracle 10.2.0.4.
When we run an application after a while it crashes. (The crashes are as frequent as 5 times a day.)
The error in the logs is ORA-03114: not connected to ORACLE - This may have corrupted data
We have checked our firewall as in the past this is what we thought was causing the issue but the firewall is not disrupting the connection.
We have tried to change the timeout settings on Oracle but this does not make a difference.
Please can you help in determining what could be causing this error.
