ps
the four byte value determined when a bit is set to one for each
corresponding state that is active. Below is the state-to-state bit mapping for
the currently defined state values:
Byte 0 1 2 3
Bits 11111111 11111111 11111111 11010000
-------- -------- -------- --------
state ABCDEFG JK NO RS UVWX YZ 1
For example, if a thread or process had a state field value of 1W, then the
following bits would be set:
Byte 0 1 2 3
Bits 00000000 00000000 00000010 00010000
-------- -------- -------- --------
state
Which when represented as a hexadecimal value would be 210.[F]
state Displays the process state. [STATE] Various values can be printed in this
field:
1 A single task using assembler callable services.
A Message queue receive wait.
B Message queue send wait.
C Communication system kernel wait.
D Semaphore operation wait.
E Quiesce frozen.
F File system kernel wait.
G MVS Pause wait.
H One or more pthread created tasks (implies M as well).
I Swapped out.
J Pthread created.
K Other kernel wait (for example, pause or sigsuspend).
L Canceled, parent has performed wait, and still session or process
group leader.
M Multi-thread.
N Medium weight thread.
O Asynchronous thread.
P Ptrace kernel wait.
R Running (not kernel wait).
S Sleeping.
T Stopped.
U Initial process thread.
V Thread is detached.
W Waiting for a child (wait or waitpid function is running).
X Creating a new process (fork function is running).
Y MVS wait.
Z Canceled and parent has not performed wait (Z for zombie).
THREAD THREAD [THREAD] is a synonym for specifying the following fields:
-m -o ruser=UID -o pid,ppid,xstid,state=STATE -o atime,syscall,args=CMD
The following is an example of how this output will appear:
UID PID PPID STID STATE TIME SYSC CMD
