- In nearly all Unixes I've seen so far process numbers are assigned
- consecutively. Thereby process numbers give an indication of the
- process creation rate, which is an interesting factor of system
- utilization. However, in AIX (at least in 3.2, but I think it holds
- for other versions/releases, too) process numbers are assigned
- somewhat ramdomly.
-
- Example (consecutive commands):
-
-
- ~> ps
- PID TTY TIME CMD
- 11416 pts/0 0:04 -tcsh
- 12555 pts/0 0:02 ps
- ~> ps
- PID TTY TIME CMD
- 11416 pts/0 0:04 -tcsh
- 12556 pts/0 0:02 ps
- ~> ps
- PID TTY TIME CMD
- 11416 pts/0 0:04 -tcsh
- 12557 pts/0 0:02 ps
- ~> date | ps
- PID TTY TIME CMD
- 10767 pts/0 0:02 ps
- 11416 pts/0 0:04 -tcsh
- ~> ps
- PID TTY TIME CMD
- 10768 pts/0 0:02 ps
- 11416 pts/0 0:04 -tcsh
- ~> ps
- PID TTY TIME CMD
- 10769 pts/0 0:02 ps
- 11416 pts/0 0:04 -tcsh
-
- Is there any meaning behind process numbers in AIX?
