SHOW SYSTEM

Displays status information about current processes.

Format

SHOW SYSTEM

Parameters

None.

Description

The SHOW SYSTEM command displays the following information about processes on the system:
Time
Process name and identification
Processing state
Priority
Total process I/O count
Cumulative processor time used
Cumulative page faults
Amount of physical memory being used
Type of process

It also checks to see whether the machine is a multiprocessor. A machine is considered a multiprocessor if the following conditions are true:

The system parameter MULTIPROCESSING is not equal to zero.
The machine accommodates more than one CPU.

If the machine is a multiprocessor, the SHOW SYSTEM command includes information about the multiprocessing environment. Each process in the currently executing state (indicated by the CUR symbol) reveals which processor it is running on. It does this by including a number beside the CUR symbol.
The SHOW SYSTEM command examines the processes on the system without stopping activity on the system. This means that process information may change during the time that SHOW SYSTEM collects the data to be displayed. As a result, there may be minor inconsistencies in the SHOW SYSTEM display. For example, SHOW SYSTEM may display two processes that schedule state CUR on the same CPU.

Qualifiers

/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.
/CLUSTER
Displays the specified processes on all nodes in an OpenVMS Cluster.
/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.
/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.
/GRAND_TOTAL

/NOGRAND_TOTAL (default)
Displays a trailing line with the total of all processes matching the selection criteria and the total number of all processes on all systems displayed by the command. (See also /TOTAL.)
/HEADING

/NOHEADING
Displays a heading line above the system output. When you use the /NOHEADING qualifier, the heading line is excluded from the display.
/IMAGE
Lists all processes with their current image. (Requires WORLD privilege.)
/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.
/IDENT=pid
Displays all processes on the system that have the specified process identification (PID) code number.
/INTERACTIVE

/NOINTERACTIVE
Displays all interactive processes on the system. When you use the /NOINTERACTIVE qualifier, all interactive processes are excluded from the display.
/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, see the HP OpenVMS Programming Concepts Manual.
/NETWORK

/NONETWORK
Displays all network processes on the system. When you use the /NONETWORK qualifier, all network processes are excluded from the display.
/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.
/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.
/OWNER_UIC=uic
Displays all processes on the system that have the specified user identification code (UIC) number.
/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.

The SHOW SYSTEM command in this example displays all processes on the system.
The information in this example includes the following:

Process identification (PID) code---A 32-bit binary value that uniquely identifies a process.
Process name---A 1- to 15-character string used to identify a process.
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.
Current priority ¹ ---The priority level assigned to the process (the higher the number, the higher the priority).
Total process I/O count¹---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.
Charged CPU time¹---The amount of CPU time that a process has used thus far.
Number of page faults¹---The number of exceptions generated by references to pages that are not in the process's working set.
Pages¹---The number of CPU-specific pages in physical memory that the process is currently occupying.
Process indicator---Letter B indicates a batch job; letter S If the letter M precedes B, S, or N, it indicates that it is a multithreaded process.
User identification code (UIC)---An 8-digit octal number assigned to a process. This number is displayed only if the /FULL qualifier is specified.
