I'm using VS 2010 on a Windows 7 (64bit) development machine and running my app on a Windows Server 2008 64bit server. I'm using .NET 2.0

Is there step-by-step instructions on how to set up for connecting to an Oracle 10g database?

In my web.config:

  <connectionStrings>
    <remove name="CentOracleServer"/>
    <add name="CentOracleServer" connectionString="Data Source=CENTRALIZED;User ID=user;Password=pass;pooling=true;min pool size=5;Max Pool Size=60" providerName="Oracle.DataAccess.Client"/>
  </connectionStrings>

Open in new window


On my page:

Imports Oracle.DataAccess.Client        
Dim oOracleConn As OracleConnection = New OracleConnection()
        oOracleConn.ConnectionString = GetConnString()
        oOracleConn.Open()
        oOracleConn.Close()

Open in new window


When I try to run it through the IDE on my dev box, I get:

Could not load file or assembly 'Oracle.DataAccess, Version=2.121.1.0, Culture=neutral, PublicKeyToken=89b483f429c47342' or one of its dependencies. An attempt was made to load a program with an incorrect format.

Make sure you downloaded the 64Bit version of ODP.Net.

Since this is all new, I would suggest you start using the new Managed Driver.  Then you don't need a complete Oracle Client install.

I've started experimenting with in in development and seem happy thus far.

All the 64Bit drivers can be found here:

I suppose I should have said:
Make sure the bit version of the app you are developing matches the bit version of the ODP driver you installed.

If it is a 32Bit app, you need the 32Bit drivers.

Going from memory here but there may be issues with the AnyCPU compiler directive.  Try forcing it to match the driver you installed.
