Web Application made using Asp.Net 1.1 C#
Host IIS: Windows 2003 Server x86, IIS 6,
Host DB: SQL Server 2005 SP2, Oracle Database 10g Release 1
In Development Environment, Certification and Testing (3 different environments), the application works correctly.
But production is not working.
The application error occurs into a specifiable screen (which accesses an Oracle DB), displays the following error:
"The connection Must Be open for this operation" (screen attached)
I believe it is due to some problem with the Oracle DLLs.
What is better way to find a solution to this error?
