Devart Forums

We are one of registered user of dotconnect for Oracle 10g.

When we access WCF data service from IIS 7.5 + Windows 2008 Server R2 then we are getting error message as

--------------------------------------
Message: Unhandled Error in Silverlight Application An error occurred while processing this request. at System.Data.Services.Client.QueryResult.EndExecute[TElement](Object source, IAsyncResult asyncResult)

same data service is working on Windows 2003 Server + IIS 6.0

Looking forward for your response.

Why have you decided that the problem is caused by dotConnect for Oracle? There are no Devart classes in your call stack. Check the inner exception to get a more detailed information about the problem.

Thanks for the response.

As I have mentioned same service is working on Windows 2003 Server.

Can you please suggest whether same oracle client for 32 bit will also work for 64 bit OS(Windows Server 2008 R2) with dotConnect for Oracle or we need 64 bit Oracle client.

The capacity of Oracle client has to coincide with the capacity of your application (or of the web server in which your service is deployed).
