Server Process

Server Process

A server process is a program that directly interacts with the Oracle server. Once a user has established a connection, a server process is started to handle the user processes requests. A server process can be either a dedicated server process or a shared server process. In a dedicated server environment, the server process handles the request of a single user process. Once a user process disconnects, the server process is terminated. In a shared server environment, the server process handles the request of several user processes. The server process communicates with the Oracle server using the Oracle Program Interface Server processes (or the server portion of combined user/server processes) created on behalf of each user's application can perform one or more of the following:

-Parse and run SQL statements issued through the application
-Read necessary data blocks from datafiles on disk into the shared database buffers of the SGA, if the blocks are not already present in the SGA
-Return results in such a way that the application can process the information
