I get the above mentioned error when I open an item in SDL Tridion 2011 SP1. (Upgraded from 2009.).
I can open the CM GUI. The list with items shows normal. I can browse everything, but when I open an item (page, component, etc) I get this error. I checked tnsnames.ora, and it seems correct. I verified this by running tnsping.exe {servicename} and it gives me an Ok (both 32bits and 64bits).
The stacktrace of the error indicates that it has something to do with the CoreService:
Component: Tridion.ContentManager.CoreService
Errorcode: 0
User: NT AUTHORITY\NETWORK SERVICE
StackTrace Information Details:
at Oracle.DataAccess.Client.OracleException.HandleErrorHelper(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, OpoSqlValCtx* pOpoSqlValCtx, Object src, String procedure, Boolean bCheck)
at Oracle.DataAccess.Client.OracleException.HandleError(Int32 errCode, OracleConnection conn, IntPtr opsErrCtx, Object src)
at Oracle.DataAccess.Client.OracleConnection.Open()
And specifically with this call: /WebUI/Models/TCM54/Services/General.svc/GetItem So it seems that the General.svc service cannot find/resolve the connection name.
Any idea's what's possibly wrong / where to look further?
I already tried/verified this: 1) Made sure that the correct tnsnames is used (how else would the list with publications show anyway?) 2) Verified the servicename in tnsnames.ora 3) Checked permissions on the oracle home folders (32bits and 64bits) 4) Repaired the installation 5) Disable loopbackcheck
Any help appreciated :)
