Displays status information about current processes.
Format
SHOW SYSTEM
| 1 - Qualifiers |
1.1 - /BATCH
/BATCH (default)
/NOBATCH
Displays all batch jobs for the local system. When used with the
/CLUSTER qualifier, the /BATCH qualifier displays all batch jobs
in the OpenVMS Cluster environment. When you use the /NOBATCH
qualifier, all batch jobs are excluded from the display.
1.2 - /CLUSTER
Displays the specified processes on all nodes in an OpenVMS
Cluster.
1.3 - /EXACT
Use with the /PAGE=SAVE and /SEARCH qualifiers to specify a
search string that must match the search string exactly and must
be enclosed with quotation marks (" ").
If you specify the /EXACT qualifier without the /SEARCH
qualifier, exact search mode is enabled when you set the search
string with the Find (E1) key.
1.4 - /FULL
Displays the user identification code (UIC), the processor type,
and the process size, in addition to the default information. The
UIC is displayed below the process name.
1.5 - /HEADING
/HEADING
/NOHEADING
Displays a heading line above the system output. When you use
the /NOHEADING qualifier, the heading line is excluded from the
display.
1.6 - /HIGHLIGHT
/HIGHLIGHT[=keyword]
Use with the /PAGE=SAVE and /SEARCH qualifiers to specify the
type of highlighting you want when a search string is found. When
a string is found, the entire line is highlighted. You can use
the following keywords: BOLD, BLINK, REVERSE, and UNDERLINE. BOLD
is the default highlighting.
1.7 - /IDENT
/IDENT=pid
Displays all processes on the system that have the specified
process identification (PID) code number.
1.8 - /INTERACTIVE
/INTERACTIVE
/NOINTERACTIVE
Displays all interactive processes on the system. When you use
the /NOINTERACTIVE qualifier, all interactive processes are
excluded from the display.
1.9 - /MULTITHREAD
Displays all multithreaded processes for the local system.
When used with the /FULL qualifier, the /MULTITHREAD qualifier
displays information about each kernel thread in a multithreaded
process.
For more information on kernel threads, refer to the OpenVMS
Programming Concepts Manual.
1.10 - /NETWORK
/NETWORK
/NONETWORK
Displays all network processes on the system. When you use the
/NONETWORK qualifier, all network processes are excluded from the
display.
1.11 - /NODE
/NODE[=(name,...)]
Displays all the processes on the specified node or nodes. If
you enter the /NODE qualifier without a value, the qualifier
displays all the processes on the local node of an OpenVMS
Cluster environment.
1.12 - /OUTPUT
/OUTPUT[=filespec]
/NOOUTPUT
Controls where the output of the command is sent. By default,
the output of the SHOW SYSTEM command is sent to the current
SYS$OUTPUT device (usually your terminal). To send the output
to a file, use the /OUTPUT qualifier followed by a file
specification.
The file specification may not include the asterisk (*) and the
percent sign (%) wildcard characters. If you enter a partial
file specification (for example, specifying only a directory),
SHOW is the default file name and .LIS is the default file type.
If you enter the /NOOUTPUT qualifier, output is suppressed.
1.13 - /OWNER_UIC
/OWNER_UIC=uic
Displays all processes on the system that have the specified user
identification code (UIC) number.
1.14 - /PAGE
/PAGE[=keyword]
/NOPAGE (default)
Controls the display of system information on the screen.
You can use the following keywords with the /PAGE qualifier:
CLEAR_SCREEN Clears the screen before each page is displayed.
SCROLL Displays information one line at a time.
SAVE[=n] Enables screen navigation of information, where n
is the number of pages to store.
The /PAGE=SAVE qualifier allows you to navigate through screens
of information. The /PAGE=SAVE qualifier stores up to 5 screens
of up to 255 columns of information. When you use the /PAGE=SAVE
qualifier, you can use the following keys to navigate through the
information:
Key Sequence Description
Up arrow key, Ctrl/B Scroll up one line.
Down arrow key Scroll down one line.
Left arrow key Scroll left one column.
Right arrow key Scroll right one column.
Find (E1) Specify a string to find when the
information is displayed.
Insert Here (E2) Scroll right one half screen.
Remove (E3) Scroll left one half screen.
Select (E4) Toggle 80/132 column mode.
Prev Screen (E5) Get the previous page of information.
Next Screen (E6), Get the next page of information.
Return, Enter, Space
F10, Ctrl/Z Exit. (Some utilities define these
differently.)
Help (F15) Display utility help text.
Do (F16) Toggle the display to oldest/newest
page.
Ctrl/W Refresh the display.
The /PAGE qualifier is not compatible with the /OUTPUT qualifier.
1.15 - /PROCESS
/PROCESS[=name] (default)
/NOPROCESS
Displays all specified processes on the system. If you do not
specify a process name with the /PROCESS qualifier, all processes
are displayed.
When you use the /NOPROCESS qualifier with the /CLUSTER
qualifier, only the node or nodes available on the cluster are
displayed with their respective uptimes and operating system
version.
You can include the asterisk (*) and the percent sign (%)
wildcard characters in the process name.
1.16 - /SCHEDULING_CLASS
/SCHEDULING_CLASS[=class_name]
/NOSCHEDULING_CLASS
Displays processes that belong to a specific scheduling class
(class_name). If the class name is not specified, all class
scheduled processes are displayed along with the name of their
scheduling class.
1.17 - /SEARCH
/SEARCH="string"
Use with the /PAGE=SAVE qualifier to specify a string that you
want to find in the information being displayed. Quotation marks
are required for the /SEARCH qualifier, if you include spaces in
the text string.
You can also dynamically change the search string by pressing the
Find key (E1) while the information is being displayed. Quotation
marks are not required for a dynamic search.
1.18 - /STATE
/STATE=process-state
Displays all processes with the specified process state. You
can include the asterisk (*) and the percent sign (%) wildcard
characters in the process-state name. The following process
states are available:
CEF COLPG COM COMO
CUR FPG HIB HIBO
LEF LEFO MUTEX PFW
PSXFR RWAST RWBRK RWCAP
RWCLU RWCSV RWIMG RWLCK
RWMBX RWMPB RWMPE RWNPG
RWPAG RWPFF RWQUO RWSCS
RWSWP SUSP SUSPO
1.19 - /SUBPROCESS
/SUBPROCESS
/NOSUBPROCESS
Displays all subprocesses on the system. When you use the
/NOSUBPROCESS qualifier, all subprocesses are excluded from the
output.
1.20 - /WRAP
/WRAP
/NOWRAP (default)
Use with the /PAGE=SAVE qualifier to limit the number of columns
to the width of the screen and to wrap lines that extend beyond
the width of the screen to the next line.
The /NOWRAP qualifier extends lines beyond the width of the
screen and can be seen when you use the scrolling (left and
right) features provided by the /PAGE=SAVE qualifier.

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.

This example displays only the nodes available on the cluster
