dedicated server vs shared server

[9iguy]

hi all...

which is the diference of using dedicated server or shared server?

And how can I change this from one to another.

is it faster the performance of database, if someone could help me would be great.

think about going to a restaurant. do you want your own waiter, or do you want to share one with other customers? If you can afford it, dedicated is better. However, at some point there are too many customers and you cannot each have your own waiter.

In a Dedicated Server environment, each user process is assigned to its own server process. In a Shared Server process, all users send requests to a small number of dispatchers (a database only needs 1 dispatcher, but you can configure more using the init.ora parameter dispatchers.) The dispatcher puts all requests into a single request queue called COMMON. All server processes read from this queue, process the requests, and put the response in the dispatcher's response queue (each dispatcher has its own response queue.)

thanks your explaining was very clear.

but you say that the dispatcher puts all requests into a single request queue called common but which critery it uses and how it decides which response is outputed first.

thanks again

the shared server process picks up the request from the common request queue and puts it in to the response queue. This is a first come first serve...

shared servers are by far more scalable if hardware resourses are limited.
