Using oracle wallet as connection for "OraclePersonalizationProvider"
I am using the OraclePersonalizationProvider to store/get the personalization/session state related details of my web application with Oracle 11g. This worked flawless without any issue. We recently started using Oracle wallet with Oracle 12c. With this change, i am unable to connect to Oracle DB to fetch the Personalization/session data. I get the below error:
Exception type: ConfigurationErrorsException
Exception message: Could not load file or assembly 'Oracle.DataAccess, Version=4.112.4.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies.

This error is only for session state. Am i missing something here. Please advice.

Hi Vinod
Can you please check in GAC 11.2.0.4 is exists or not
MS command prompt > Gacutil -l Oracle.DataAccess
Thanks

Your application cannot find ODP.NET 11.2.0.4. It's likely loading another ODP.NET version, finds that your app requires ODP.NET 11.2.0.4, then errors out when there is no match.
