What is Process Instance

[Luca Gabrielli]

Hi
I'm very confused about Process Instance.
1) the right definition of Process Instance
2) whith ps can I see all the instance of a process?
3) every instance have a single PID?

thank you

the "ps -ef" command shows all the processes running on a particular server. if you want to see all the instances of a particular process, you could grep for it, or use awk or sed.

2) yes, ps -ef will give you every process instance running on the system.
3) Every process (by definition) has it's own PID.

2) whith ps can I see all the instance of a process?
== Yes. "ps" command show what all processes are running on the system. Using different swicthes with ps you can have more details associated with the processes.

3) every instance have a single PID?
== Yes. PID is unique and proccesses are identified with their PID's by the systems.
