Introduction To Processes

All connected Oracle users must execute two modules of code to access an Oracle database instance:

-Application or Oracle tool
-Oracle server code

These code modules are executed by processes. A process is a "thread of control" or a mechanism in an operating system that can execute a series of steps. (Some operating systems use the terms job or task. A process normally has its own private memory area in which it runs.
The process structure varies for different Oracle configurations, depending on the operating system and the choice of Oracle options. There are some processes

-User Process
-Server Process
-Background Process
