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.
First Question: What has changed in the RDBMS or the client in the last week?
What version of ArcGIS Client are you using?
Are you using direct connection, if so what is the syntax? EZConnect or TNS?
Can you put a screenshot of the error?
Since it is Oracle, can you connect to the DB via SQLPlus or TOAD as the SDE user?
Thanks for that information, I am not sure how to make a connection via C++.
Can you make a connection directly in the ArcGIS Client (Catalog/ArcMap)? What are the results?
Ok, If you can connect to the Oracle GDB via Catalog that tells me that it is something in the C++ code that may need to be tweaked.
Ok, then a comparison between a "working" machine and this "non-working" machine needs to be made.
