ORA-02068, ORA-03135 error Solution

Today, I checked the alter _ <SID>. log of the ERP DB server and found an error.

Sat Sep 14 14:49:42 CST 2013
Error 2068 trapped in 2 PC on transaction 47.12.104933. Cleaning up.
Error stack returned to user:
ORA-02068
ORA-03135

ERPSALES indicates that this is related to another system. After checking the entire log, it is found that this error occurs almost every month in the past.

On the Network looked at the ORA-02068, ORA-03135 related errors, more similar:

This is because the SQL timeout time on the server side is too short. The temporary solution is to modify the sqlnet. ora parameter SQLNET. EXPIRE_TIME = 0 (unlimited) on the server side)
