SHOW, CPU, Qualifiers
*Conan The Librarian
1 - /ACTIVE_SET
Selects as the subject of the display only those processors that are members of the system's active set.
2 - /ALL
Selects all configured processors, active and inactive, as the subject of the display.
3 - /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.
4 - /CONFIGURE_SET
/CONFIGURE_SET (Alpha 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.
5 - /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.
6 - /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, refer to the OpenVMS I/O User's Reference Manual.
7 - /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.
8 - /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.
9 - /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.
10 - /POTENTIAL_SET
/POTENTIAL_SET (Alpha 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.
11 - /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.
12 - /STANDBY_SET
/STANDBY_SET (Alpha 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.
13 - /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.
14 - /SYSTEM
/SYSTEM (Alpha only) Displays platform-specific hardware information relating to the current instance.
15 - /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.
