Limitations of 64bit Data Access on Windows

Some database do not yet have 64bit windows APIs drivers, preventing native 64bit access from windows.  The following is a list of datasources with such limitations.

NOTE - this grid only applies if the data being accessed resides on windows.  If the data is on another server, VMS for example, the 64bit Client component will use TCP/IP to communicate to the server component on another platform, and results in no limitations.
 

In other words, if the data being access is on a non-windows system, or the enterprise server service is being used on windows, there is no 64bit limitation.
