Is 64-bit ODP.NET supported?
64-bit ODP.NET for 64-bit Windows x64 (AMD64 and EM64T) and for 64-bit Windows Itanium can be downloaded here. Q: How do I use distributed transactions with ODP.NET? A: The Oracle Services for MTS (OraMTS) is required for distributed transaction support with COM+/Enterprise Services/Microsoft Transaction Server. OraMTS is available to download for free on OTN. Q: I have two .NET applications on the same machine running two different versions of ODP.NET. How do I ensure both these applications use the correct ODP.NET version? A: Beginning with ODP.NET 10.1.0.3, the Oracle installer will register the following publisher policy DLLs in the Global Assembly Cache (GAC) that redirect 9.2, 10.1 and 10.2 ODP.NET applications to use the last installed version of ODP.NET: Policy.9.2.Oracle.DataAccess.dll and Policy.10.1.Oracle.DataAccess.dll. ODP.NET 9.2 includes just the first policy DLL above. These policy files ensure that all your ODP.NET applications use the most recently installed version
