My application have performance issues, so i started to investigate this from the root: "The connection with the database". The best practices says: "Open a connection, use it and close is as soon as possible", but i dont know the overhead that this causes, so the question is: 1 -"Open, Use, Close connections as soon as possible is the best aproach using ODP.NET?" 2 - Is there a way and how to use connection pooling with ODP.NET? I thinking about to create a List to store some connections strings and create a logic to choose the "best" connection every time i need. Is this the best way to do

We use ODP.NET to perform queries on Oracle databases, and normally it works fine. There is a particular database, and a particular view in that database, though, that we just can't complete a query on from .NET. For example: SELECT some_varchar_field FROM the_view WHERE ROWNUM < 5; If I execute this query from within Oracle SQL developer, it finishes in less than a second. If I do an identical query from our .NET application using ODP.NET, it hangs and eventually produces an "ORA-03135: connection lost contact" error. I think that limiting it to just a few rows eliminates the possibility that

I have Windows 8.1 64-bit with Visual Studio 2013. I've installed the latest Oracle ODAC 12c Release 3 32-bit beta which claims to supports EF 6.

It says 'An Entity Framework database provider compatible with the latest version of the Entity Framework could not be found for your data connection'. Why is that? I did the following to make it work :- First Installing ODAC 12c

I have a XCOPY deployable .NET application using Oracle.DataAccess (ODP.NET). We also deploy the Oracle Instant client in the application directory. Everything works OK, but I worry.. From the Oracle ODP.NET FAQ: 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 This means that on machines where the Oracle ODP.NET is installed, the
