questions about job scheduling

621436Feb 5 2008 — edited Apr 22 2008

i am a newbie in oracle, and i have several quesions about the scheduler.
1 If I just have one job class, and there are many concurrent jobs inside. Then, how does oracle exactly schedule those jobs with the same priority?(Will they run for several time slices each time or be executed until completed one by one?)

2 How does oracle exactly schedule those jobs with different priorities?

3 If I have two job classes, how will oracle schedule those jobs in these two classes?(each of them is assigned some time slices based on the cpu allocation?)

I have checked many turorials from oracle, but I have not got any detailed explanations or examples to show how oracle will exactly do it. I am currently doing some QoS management in an application based on oracle, so I am in great need of those information and details inside the scheduler.

Thanks a lot.
