-
The user starts a tool (SQL*Plus, Oracle Forms, ...) as a user process
--> a server process is created on the Oracle Server
--> the server process communicates with the instance on behalf of the user process
-
Connection = communication pathway between a user process and the Oracle server through :
a local connection (local access tool --> local Oracle server)
or
a client-server connection (local access tool --> network --> remote Oracle server)
or
a three-tiered connection (local access tool ie browser --> network
--> remote Application server --> network --> remote Oracle
server)
- Session = specific connection from a client to the server (login/logout)
