Figure 7 shows the same thing as the previous one but here you might have noticed that we have less number of blocks, especially there is no Dispatcher process and no Request and Response Queue. This is because; here we are showing Oracle working in Dedicated Server mode.



In dedicated server mode, each connected user is entertained by a separate server process. Although this configuration would be having high idle server time as most of the time Server process would be doing nothing and waiting for next SQL statement to arrive. This configuration has high performance factor but it should only be utilized when you have plenty of system resources available.
