Qualifiers
/ACTIVE_SET
Selects as the subject of the display only those processors that
are members of the system's active set.
/ALL
Selects all configured processors, active and inactive, as the
subject of the display.
/BRIEF
Produces information from the summary display and also lists the
current CPU state and current process (if any) for each processor
in the configuration.
/CONFIGURE_SET
/CONFIGURE_SET (Alpha/Integrity servers only)
Selects as the subject of the display only those processors
that are members of the system's configure set - those that are
actively owned and controlled by the current instance.
/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
Produces information from the summary display. The /FULL
qualifier also lists the current CPU state, the current process
(if any), the revision levels, and the capabilities for each
configured processor. It indicates which processes can execute
only on certain processors in the configuration. In addition, if
one or more uniprocessing drivers are present in the system, the
/FULL qualifier lists them by name.
The SHOW CPU/FULL command lists the current process on each
configured processor without stopping other activity on the
system. The current process may change while the data is
displayed. As a result, there may be apparent inconsistencies in
the display. For example, a process may be listed as the current
process on more than one CPU.
This qualifier also displays whether the CPU is enabled or
disabled for use as a Fast Path preferred CPU, then lists the
Fast Path ports assigned to it, and shows whether or not the
ports are user-assigned.
For more information about using Fast Path features to improve
I/O performance, see the VSI OpenVMS I/O User's Reference Manual.
/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.
/OUTPUT
/OUTPUT[=filespec]
/NOOUTPUT
Controls where the output of the command is sent. If you do
not enter the qualifier, or if you enter the /OUTPUT qualifier
without a file specification, the output is sent to the current
process default output stream or device, identified by the
logical name SYS$OUTPUT.
If you enter the /OUTPUT qualifier with a partial file
specification (for example, specifying only a directory), SHOW
is the default file name and .LIS the default file type. If you
enter a file specification, it may not include the asterisk (*)
and the percent sign (%) wildcard characters.
If you enter the /NOOUTPUT qualifier, output is suppressed.
/PAGE
/PAGE[=keyword]
/NOPAGE (default)
Controls the display of device 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.
/POTENTIAL_SET
/POTENTIAL_SET (Alpha/Integrity servers only)
Selects as the subject of the display only those processors that
are members of the system's potential set - those CPUs in the
hard partition that meet the current instance's requirements to
join its active set.
Inclusion in this set does not imply that the CPU is (or ever
will be) owned by the current instance. The potential set
only describes those physically existing CPUs that currently
meet the instance-specific hardware and software compatibility
constraints, should they ever become available.
/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.
/STANDBY_SET
/STANDBY_SET (Alpha/Integrity servers only)
Selects as the subject of the display only those processors that
are members of the system's standby set - those CPUs in the hard
partition that are not currently owned by soft partitions.
Supported only on AlphaServer systems that support partitioning.
/SUMMARY
Produces a display listing the processors in the OpenVMS
multiprocessing or single-CPU system, indicating which is the
primary processor, which processors are configured, and which
processors are active.
The /SUMMARY qualifier also indicates the minimum revision
levels required for processors in the system, which OpenVMS
synchronization image has been loaded into the operating system,
and whether multiprocessing is enabled. If the presence of one or
more uniprocessing drivers in the system prohibits the enabling
of multiprocessing, the SHOW CPU command displays a warning
message.
/SYSTEM
/SYSTEM (Alpha/Integrity servers only)
Displays platform-specific hardware information relating to the
current instance.
/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.
