Figure 5-4: Restaurant running under dedicated waiter mode. It is
similar to running Oracle Instance under Dedicated Server Mode.
If you are having unlimited resources available then to achieve
ultimate performance always go with Dedicated Waiter (Server)
mode otherwise stick with the Shared Server Mode. In real world
the word “Resources” means money whereas in computer world
this term stands usually for “RAM/Memory”.
Rest of the processes works the same way like in case of Shared
Server mode. In Dedicated server mode we have more server
“idle time” or in other words server process doing nothing
waiting for user request.
Let me give you an idea how to find out which will work best for
you, Shared Server or Dedicated Server. Each Dedicated Server
takes approximately of 20MB of memory. If your system
running Oracle have 1 GB of RAM available and your Oracle
system needs to support 10 users and on the average of 7
concurrent users. Under this scenario always go with Dedicated
Server Mode otherwise stick with Shared Server Mode.
