*Conan The Librarian
Displays information about a process and its subprocesses. Requires GROUP privilege to show other processes in the same group. Requires WORLD privilege to show processes outside your group. You must use the /IDENTIFICATION qualifier to look at processes outside of your group. Format SHOW PROCESS [[node-name::]process-name]
|1 - Parameters|
node-name:: The name of the node on which the specified process is running. You must specify a node name on the same OpenVMS Cluster on which the current process is running. process-name The name of the process about which information is to be displayed. The process name can have up to 15 alphanumeric characters. The specified process name must be in the same group as the current process. You must use the /IDENTIFICATION qualifier to look at processes outside of your group.
|2 - Qualifiers|
2.1 - /ACCOUNTING
Shows the resources used by the process.
2.2 - /ALL
Displays the basic subset of information as well as information about: Accounting Dynamic memory use Privileges Quotas Shelving Subprocesses
2.3 - /CONTINUOUS
Displays continuously updated information about the local process in an OpenVMS environment. You cannot use the /CONTINUOUS qualifier to display information about a process on another node in a cluster environment. While the continuous display is running, you can press the T key to display information for threads that make up the process. If there are multiple threads, pressing the T key repeatedly cycles through all the threads. While the continuous display is running, you can press the V key to display a map of the pages in the virtual address space of the process. Each character displayed in the map represents the type of page. If the current program counter is in the page, the page type is indicated by an at sign (@). Pages locked in the working set are indicated by the letter L. Global pages are indicated by the letter G. Other valid pages in the working set are indicated by an asterisk (*). To terminate the continuous display, press the E key. To return to the original display, press the space bar. The /CONTINUOUS qualifier may not be used with the /OUTPUT qualifier.
2.4 - /DUMP
Displays the image dump setting which is set or cleared by the SET PROCESS/DUMP command.
2.5 - /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.
2.6 - /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.
2.7 - /IDENTIFICATION
/IDENTIFICATION=pid Requires GROUP or WORLD privilege to access processes other than your own. Displays information about the process with the specified process identification (PID). The PID is assigned by the system when the process is created. When you specify a PID, you can omit the leading zeros. If you specify the /IDENTIFICATION qualifier, it overrides the process-name parameter. If, in addition, you specify the /MEMORY qualifier, the PID value must be that of the current process.
2.8 - /INTERVAL
/INTERVAL=n Use with the /CONTINUOUS qualifier to update the information at the specified number of seconds.
2.9 - /MEMORY
Displays the process's use of dynamic memory areas. The /MEMORY qualifier is allowed only for the current process.
2.10 - /OUTPUT
/OUTPUT[=filespec] /NOOUTPUT Controls where the output of the command is sent. By default, the output of the SHOW PROCESS 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 asterisk (*) and the percent sign (%) wildcard characters are not allowed in the file specification. 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. The /OUTPUT qualifier is incompatible with the /CONTINUOUS qualifier.
2.11 - /PAGE
/PAGE[=keyword] /NOPAGE (default) Controls the display of process 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.
2.12 - /PRIVILEGES
Displays current privileges and rights for the process. To display only privileges, also specify the /NORIGHTS qualifier. Use the SET PROCESS/PRIVILEGES command to enable process privileges on a system. Use the SHOW PROCESS/PRIVILEGES command to determine what authorized privileges are enabled on an OpenVMS system: ACNT ALLSPOOL ALTPRI AUDIT BUGCHK BYPASS CMEXEC CMKRNL DETACH DIAGNOSE DOWNGRADE EXQUOTA GROUP GRPNAM GRPPRV IMPORT LOG_IO MOUNT NETMBX OPER PFNMAP PHY_IO PRMCEB PRMGBL PRMMBX PSWAPM READALL SECURITY SETPRV SHARE SHMEM SYSGBL SYSLCK SYSNAM SYSPRV TMPMBX UPGRADE VOLPRO WORLD
2.13 - /QUOTAS
Displays, for each resource, either a quota or a limit. The values displayed for quotas reflect any quota reductions resulting from subprocess creation. The values displayed for limits reflect the resources available to a process at creation.
2.14 - /RAD
/RAD (Alpha only) Displays home resource affinity domain (RAD). Supported only on AlphaServer GS series systems.
2.15 - /RIGHTS
/RIGHTS (default) /NORIGHTS Displays the current rights for the specified process. Use the /NORIGHTS qualifier with the /PRIVILEGES qualifier to suppress the rights display.
2.16 - /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.
2.17 - /SHELVING
Displays whether the process automatically unshelves files.
2.18 - /SUBPROCESSES
Displays the current subprocesses in hierarchical order.
2.19 - /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 current process is indicated by the asterisk (*). Processes both below and above the current process are shown. 6.$ SHOW PROCESS/CONTINUOUS BOB Process BOB 12:26:53 State CUR Working set 269 Cur/base priority 8/4 Virtual memory 1713 Current PC 7FFEE07E CPU time 00:00:13.82 Current PSL 03C00000 Direct I/O 246 Current user SP 7FF785A4 Buffered I/O 646 PID 226006C0 Page faults 3417 UIC [VMS,BOB] Event flags C8000007 C0000000 SYS$SYSROOT:[SYSEXE]SHOW.EXE In this example, the /CONTINUOUS qualifier causes the display of information about process BOB to be updated continuously. Note that the Virtual memory heading appears on VAX and the Virtual pages heading appears on Alpha; both indicate the virtual memory used as a number of CPU-specific pages. The value displayed for Working set is also a number of CPU- specific pages. 7.$ SHOW PROCESS/MEMORY 14-DEC-2001 14:59:04.48 User: MALIK Process ID: 28200364 Node: OCALA Process Name: "MALIK" Process Dynamic Memory Area Current Size (bytes) 25600 Current Total Size (pages) 50 Free Space (bytes) 22698 Space in Use (bytes) 2902 Size of Largest Block 22496 Size of Smallest Block 15 Number of Free Blocks 7 Free Blocks LEQU 32 Bytes 3 The SHOW PROCESS command in this example displays the use of dynamic memory areas for the current process, MALIK. These areas are described as follows: Current size Displays the current size in bytes and pages on VAX (512-byte pagelets on Alpha) of each dynamic memory area. Free space Displays the amount of free space in each dynamic memory area. Space in use Displays the amount of space currently allocated from each area. Largest block Displays the size of the largest contiguous area in each pool area. Smallest block Displays the size of the smallest free block in each pool area. Free blocks Displays the total number of free blocks in each pool area. The size of this number is a measure of pool fragmentation. Blocks LEQU 32 Displays the number of free blocks that are (VAX) Blocks LEQU 32 bytes or shorter on VAX or 64 bytes or 64 (Alpha) shorter on Alpha. This number is another measure of pool fragmentation, because while allocation of these small blocks is unlikely, they contribute to the allocation time whenever an allocation request is made. 8.$ SHOW PROCESS OCALA::MALIK 14-DEC-2001 15:35:19.39 User: MALIK Process ID: 28200364 Node: OCALA Process name: MALIK Terminal: RTA5: User identifier: [VMS,MALIK] Base priority: 4 Default file spec: WORK5:[MALIK] Devices allocated: RTA5: The SHOW PROCESS command in this example displays the basic subset of information for the process MALIK on node OCALA. 9.$ SHOW PROCESS/SHELVING LYONS 15-JUNE-2001 10:07:25.11 User: LYONS Process ID: 20206A50 Node: BANANA Process name: "LYONS" Auto-unshelve: on The SHOW PROCESS command in this example shows that the LYONS process automatically unshelves files. 10$ SHOW PROCESS/DUMP RALSTON 31-DEC-2001 10:38:32.48 User: RALSTON Process ID: 20C0011B Node: AAAAAA Process name: "_RTA1:" Image Dump: on The SHOW PROCESS command in this example shows that the image dump capability for the RALSTON process is enabled. This causes the contents of the address space to be written to the file named SYS$LOGIN:(image-name).DMP (where the image name is the same as the file name) when an image terminates due to an unhandled error. See the SET PROCESS/DUMP command for additional information.
