I have an existing database on server 12.1 enterprise. I have an application that was connected to this db on a client. However the client had to be replaced. I could not find a download for a client matching the server version so i downloaded and installed 19. The application needs to use the ole db provider for oracle. What is the proper technique to use this driver. My variables are the Oracle_Home is pointed to the Oracle_Home\bin. The path is pointed to the same directory. I thought i needed to setup a DSN but unsure because i need the ole db not odbc. Is that accurate? I'm sure it needs some sort of "pre-connect" like a DSN but i dont know what that is. Please help! :)
