I have an application that was developed at a time when we had a client-server system, with this there was always an Oracle client on each machine, now we have a 3 layer system and we no longer have this Client.
I would like to know how to make a Delphi-Oracle connection without Oracle Client
Versions
Delphi: Embarcadero RAD Studio 2010
Oracle: Version 11g
Thank you in advance
