We have a IIS web application built and referencing Oracle.DataAccess 2.102.2.20 running on a Windows 2003 Enterprise Server with no problems connecting to Oracle 11gR2. We are trying to move it to a Windows 2008 R2 server with the Oracle Client 12 installed which has Oracle.DataAccess 2.121.1.0 version and Policy.2.102.Oracle.DataAccess with a 32bit enabled application pool. The problem is the web application is reporting the following error:
Could not load file or assembly 'Oracle.DataAccess, Version=2.102.2.20, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. The system cannot find the file specified.
why? isn't the policy suppose to make the request use the installed 2.121.1.0 version of Oracle.DataAccess? how do I go about correcting the issue without rebuilding/compiling the web application (developer no longer available)?
Thanks for help
