When I am trying to connect to the Geodatabase with sde user but the connecting not establishing and getting a -51 error code with message "Underlying DBMS error". Previously I had no issue connecting Geodatabase but from a week I am getting this error.  I am using Oracle11g and ArcSDE 10.1.


Is this something related to ArcSDE or DBMS? If it is related to DBMS what could be the cause of the issue and how can I resolve it?.


Any help in identifying and resolving the issue is greatly appreciated.


Thanks in Advance.
