I have a server running WIndows 2008 64bit and SQL Server 2012 64bit. I have both the 32bit and 64bit Oracle ODBC drivers installed. 32bit is for SSIS and SSRS uses 64bit. I have an ODBC connection setup for both the 32bit and 64bit. I have the datasources setup for the 64bit and when I test it it works. When I go to run a query I get TNS timeout errors. Any ideas?
