The SHOW SYSTEM command in this example displays all processes
on the system.
The information in this example includes the following:
o Process identification (PID) code-A 32-bit binary value that
uniquely identifies a process.
o Process name-A 1- to 15-character string used to identify a
process.
o Process state-The activity level of the process, such as COM
(computing), HIB (hibernation), LEF (local event flag) wait,
or CUR (if the process is current). If a multiprocessing
environment exists, the display shows the CPU ID of the
processor on which any current process is executing.
Note that the SHOW SYSTEM command examines the processes on
the system without stopping activity on the system. In this
example, process information changed during the time that
the SHOW SYSTEM command collected the data to be displayed.
As a result, this display includes two processes, named
GAWAIN and S. Whiplash, with the state CUR on the same CPU,
CPU ID 6 in the example.
o Current priority -The priority level assigned to the process
(the higher the number, the higher the priority).
o Total process I/O count-The number of I/O operations
involved in executing the process. This consists of both
the direct I/O count and the buffered I/O count.
o Charged CPU time-The amount of CPU time that a process has
used thus far.
o Number of page faults-The number of exceptions generated by
references to pages that are not in the process's working
set.
o Pages-The number of CPU-specific pages in physical memory
that the process is currently occupying.
o Process indicator-Letter B indicates a batch job; letter
S indicates a subprocess; letter N indicates a network
process.
o User identification code (UIC)-An 8-digit octal number
assigned to a process. This number is displayed only if
the /FULL qualifier is specified.

The SHOW SYSTEM command in this example was issued from an
Alpha system and shows all processes on all nodes of the
cluster.

The SHOW SYSTEM command in this example was issued from a VAX
system and shows all processes on the node EON.

This example displays only the nodes available on the cluster
with their respective uptimes and operating system versions
because the /NOPROCESS qualifier suppresses the display of
processes. The /FULL qualifier also displays the type of
hardware on which the system is running.
5.$ SHOW SYSTEM/PROCESS=S*

This example displays only the processes on the system that
begin with the letter S.

This example places the display of system processes into the
SYSPROC.DAT file without the heading information using the
/OUTPUT qualifier. In this way, you can create a data file
for processing because the heading is suppressed using the
/NOHEADING qualifier.

BESTON.

that begin with the letter L.

and the combination results of the /MULTITHREAD and /FULL
qualifiers.
