How do you determine which dbclient connection property to use for an Oracle SQLWorkspace connection?

I have an Oracle11g database that I connect to via a SQL Workspace; however the actual dbclient string value that works differs depending on machine (and I’m guessing oracle client configuration). On some machines, its Oracle11g(like the example on resources.arcgis.com):

// Create the connection properties.
IPropertySet connectionProps = new PropertySetClass();
connectionProps.SetProperty("dbclient", "Oracle11g");
connectionProps.SetProperty("serverinstance", "Riverside");
connectionProps.SetProperty("authentication_mode", "DBMS");
connectionProps.SetProperty("user", "BlackDog");
connectionProps.SetProperty("password", "123456");

Sometimes it’s Oracle.

// Create the connection properties.
IPropertySet connectionProps = new PropertySetClass();
connectionProps.SetProperty("dbclient", "Oracle");
connectionProps.SetProperty("serverinstance", "Riverside");
connectionProps.SetProperty("authentication_mode", "DBMS");
connectionProps.SetProperty("user", "BlackDog");
connectionProps.SetProperty("password", "123456");

How is that dbclient value used by ArcGIS? Is there a way to detect which is needed at runtime?
