We use OCIServerAttach and pass the service name as defined in Oracle Net8.
It handles all the socket interfacing. We then followup with repeated
OCIAttrSet calls to set the userid, password and server attribute and then
logon through an OCISessionBegin call, a OCIAttrSet call to set up the
session attribute and then do the actual OCILogon call.
