OpenVMS DCL Dictionary

The /PAGE qualifier is not compatible with the /OUTPUT qualifier.

/PRODUCER=producer-name

Displays software product licenses active on the current node and supplied by the specified producer. The asterisk (*) and the percent sign (%) wildcard characters are allowed for the producer-name parameter. You cannot use the /PRODUCER qualifier with the /UNIT_REQUIREMENTS qualifier.

/RELEASE_DATE=[date_time]

Allows listing licenses using release dates as selection criteria.

/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.

/SINCE(default)

Use with the /TERMINATION_DATE and /RELEASE_DATE qualifiers. Selects only those licenses whose times are after the time specified with the other qualifiers.

The /SINCE qualifier cannot be used with the /BEFORE qualifier.

/TERMINATION_DATE=date_time

Allows listing licenses using termination dates as selection criteria.

/UNIT_REQUIREMENTS

Displays information in the License Unit Requirement Table (LURT). The /UNIT_REQUIREMENTS qualifier is incompatible with the product-name parameter and with the /BRIEF and /PRODUCER qualifiers.

/USAGE

Tells you how many license units are loaded, how many are currently allocated, and how many are currently available, as well as the license type for each product on the system. Use with the /FULL qualifier to display complete information---including the PID, process name, node, or user name---for each instance of use of the product. You need group privilege to see the list of users in your group who have allocated license units; you need world privilege to see the list of users in all groups.

In an OpenVMS Cluster, if you own multiple license types for a single product, you are limited to viewing the usage information for the license type loaded on the node from which you are executing the SHOW LICENSE/USAGE command. To find out the usage of the other license type loaded on another node, issue the command on that node. You can also use the System Management (SYSMAN) utility to do this.

In anOpenVMS Cluster, usage information is limited to the local license type. For example, VAX and Alpha availability licenses are considered by LMF to be different license types. If you are running both VAX and Alpha systems in a cluster, usage information for availability licenses is limited to the local system type. For example, if you have DEC C installed on all nodes in your OpenVMS Cluster, you can display DEC C license allocation on all the VAX nodes in the cluster from any VAX node with DEC C installed, but you cannot display the DEC C license allocation on the Alpha nodes.

Usage information is not available for unlimited licenses (a license with 0 units). Clusterwide usage information is not available for personal use or NO_SHARE licenses. See the OpenVMS License Management Utility Manual for more information on license types.

/WARNING_INTERVAL=n

NOWARNING_INTERVAL

Displays a warning stating the number of licenses that will terminate in n days. The default is 30 days.

/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 LICENSE command in this example lists the current users of the activity license for the product DECwrite. For each instance of use of the product, the process identification (PID), process name, node, and user name are identified. The units column shows the number of units allocated for each particular invocation of the product. The last line displays the units loaded when the LICENSE LOAD command was given, the total number of units currently allocated, and the total of unused (available for others to use) units.

This example shows a personal use license. The DEC TEST_PER product has enough units for six reservations with 100 units for each reservation. The license database (LDB) only has a total of four names in the reserve list attached to this product. If the license administrator (usually the system manager) wants to take full advantage of this license and adds 2 more names to the reserve list, he should use the following commands to update the product information:
$ LICENSE MODIFY TEST_PER/RESERVE=(NAME, ANOTHER_NAME)/ADD
$ LICENSE UNLOAD TEST_PER
$ LICENSE LOAD TEST_PER
If this product is used in a cluster environment, you may use the SYSMAN Utility to unload and load the license.

Units loaded: 620    Units allocated: 1220    Units available: ***

In this example, the number of units allocated appears to be greater than the total units loaded and the units available value is three asterisks (***).
When you see three asterisks (***) as the number of units available, it is generally not a cause for alarm. This situation might arise when the license database (LDB) has been updated on disk, but the new information has not been propagated to the license database in memory on all nodes in the cluster. This node, SLTG24, happens to be one of the nodes that has not received the latest LDB information.
To update the information in the license database in memory for the TEST_CAP product, enter the following commands:
$ LICENSE UNLOAD TEST_CAP
$ LICENSE LOAD TEST_CAP
The next time you issue the SHOW LICENSE/USAGE command the three asterisks (***) in display should disappear. If, however, you are using multiple LDB files in a cluster, you should read the section on the license database in the OpenVMS License Management Utility Manual.

In this example, the display shows how many license units are required for each license type (A, B, etc.) on each node in the cluster. If a row of three asterisks (***) is displayed for a node, it means that the node is in the process of booting.

SHOW LOGICAL

Displays translations, the level of translation, and the logical name table for a specified logical name. The SHOW LOGICAL command performs iterative translations.
Requires read (R) access to the table in which a logical name is cataloged to display information about the logical name.

Format

SHOW LOGICAL [logical-name[:][,...]]

PARAMETER

logical-name[:][,...]
Specifies one or more logical names whose translations you want to display. The asterisk (*) and the percent sign (%) wildcard characters are allowed. However, if a wildcard character is used, iterative translation is not done.
The logical name is translated iteratively up to a number of times determined by the system (from 9 to 11). That is, translations are examined to see if they are also logical names.

DESCRIPTION

The SHOW LOGICAL command displays logical names.
The logical name LNM$DCL_LOGICAL contains the list of logical name tables and the order in which they are searched. Unless LNM$DCL_LOGICAL has been redefined, the process, job, group, and system tables are searched, in that order. (To see how LNM$DCL_LOGICAL is defined for your process, enter the command SHOW LOGICAL/TABLE=LNM$DIRECTORIES LNM$DCL_LOGICAL.)
If you specify a logical name, its translations are displayed. If you do not specify a logical name, all the logical names in the tables defined by the logical name LNM$DCL_LOGICAL are displayed.
You can specify the tables you want to search. If you do not specify a table, SHOW LOGICAL searches the tables specified by the logical name LNM$DCL_LOGICAL.
The SHOW LOGICAL command performs iterative translations. If a logical name has more than one translation, then all translations at a level are displayed before going to the next level. Use the SHOW TRANSLATION command to display only the first translation found for a specified logical name.
The SHOW LOGICAL command executes an image and causes the current image (if any) to exit. Use the SHOW TRANSLATION command (which is built into the command interpreter) when you do not want to exit the current image.
If a logical name contains control characters, the SHOW LOGICAL command replaces them with periods (.) for display.

QUALIFIERS

/ACCESS_MODE=mode
Displays names defined in the specified access mode and any inner access modes. You can specify one of the following keywords to indicate the access mode: USER_MODE, SUPERVISOR_MODE, EXECUTIVE_MODE, or KERNEL_MODE.
The default value for this qualifier is USER_MODE; by default any definitions in all four access modes are displayed.
/ALL (default)
Indicates that all logical names in the specified logical name tables are to be displayed. If you do not enter the /PROCESS, the /JOB, the /GROUP, the /SYSTEM, or the /TABLE qualifier, all logical names in the tables specified by the logical name LNM$DCL_LOGICAL are displayed.
/DESCENDANTS

/NODESCENDANTS (default)
Controls whether the system displays names from the specified logical name table and any descendant tables. A descendant table is created by the CREATE/NAME_TABLE command, with the /PARENT_TABLE qualifier specifying its parent table. If you use the /DESCENDANTS qualifier, you must also use the /TABLE qualifier.
/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 more detailed information for the specified logical name. The information includes the access mode, attributes, the translation, and the logical name table.
/GROUP
Indicates that only the group logical name table is to be searched. The /GROUP qualifier is synonymous with the /TABLE=LNM$GROUP qualifier. If you specify the /GROUP qualifier and you do not also specify a logical name, all names in the group table are displayed.
/HIGHLIGHT[=keyword]

/NOHIGHLIGHT (default)
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.
/JOB
Indicates that only the job logical name table is to be searched. The /JOB qualifier is synonymous with the /TABLE=LNM$JOB qualifier. If you specify the /JOB qualifier and you do not also specify a logical name, all names in the job logical name table are displayed.
/OUTPUT[=filespec]

/NOOUTPUT
Controls where the output of the SHOW LOGICAL command is sent. By default, the output of the SHOW LOGICAL 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.
/PAGE[=keyword]

/NOPAGE (default)
Controls the display of 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 (<uparrow symbol>), Ctrl/B Scroll up one line.

Down arrow (<downarrow symbol>) Scroll down one line.

Left arrow ( <-) Scroll left one column.

Right arrow (->) 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), Return, Enter, Space Get the next page of information.

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.
/PROCESS
Indicates that only the process logical name table is to be searched. The /PROCESS qualifier is synonymous with the /TABLE=LNM$PROCESS qualifier. If you specify the /PROCESS qualifier and you do not also specify a logical name, all names in the process table are displayed.
/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.
/STRUCTURE

/NOSTRUCTURE (default)
Controls whether the system displays the "family tree" of all accessible logical name tables. The display includes the two logical name directory tables (process and system) and all logical name tables cataloged in these directory tables. Any descendant logical name tables are shown under their parent tables.
If you specify the /STRUCTURE qualifier, you cannot use any other qualifiers except /ACCESS_MODE, /FULL, and /OUTPUT.
/SYSTEM
Indicates that only the system logical name table is to be searched. The /SYSTEM qualifier is synonymous with the /TABLE=LNM$SYSTEM qualifier. If you specify the /SYSTEM qualifier and you do not also specify a logical name, all names in the system table are displayed.
/TABLE=(name[,...])
Specifies the tables you want to search. If you specify only one table, you can omit the parentheses. The asterisk (*) and the percent sign (%) wildcard characters are allowed. Names with wildcards are used to match table names. Names without wildcard characters are treated both as table names and table search lists (whichever is appropriate).
You can use the /TABLE qualifier to specify the following:

A user-defined logical name table (created with the CREATE/NAME_TABLE command)
The process, group, or system logical name tables
The process or system directory tables

If you specify the table name by using a logical name that translates to more than one table, then each table is searched in the order specified. For example, if you specify SHOW LOGICAL/TABLE=LNM$FILE_DEV, and LNM$FILE_DEV is equated to LNM$PROCESS, LNM$JOB, LNM$GROUP, and LNM$SYSTEM, then the process, job, group, and system tables are searched, in that order.
If you do not specify the /TABLE qualifier, the default is /TABLE=LNM$DCL_LOGICAL.
/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.

  "SYS$LOGIN_DEVICE" = "WORK6:" 
  "SYS$OUTPUT" = "_TTB4:" 
  "SYS$OUTPUT" = "DBA2:" 
  "SYS$SCRATCH" = "WORK6:[ODONNELL]"

The SHOW LOGICAL command in this example displays all process logical names and their translations. (Note that /TABLE=LNM$PROCESS would produce the same display as /PROCESS.)

$ SHOW LOGICAL INFILE
  "INFILE" = "WORK6:[LOGAN]PAYROLL.EXE" (LNM$PROCESS_TABLE)

The SHOW LOGICAL command in this example displays the translation for the logical name INFILE. The response indicates that the logical name was found in the process logical name table.

$ SHOW LOGICAL/GROUP
   .
   .
   .

The SHOW LOGICAL command in this example displays all group logical names and their translations. (Note that /TABLE=LNM$GROUP would produce the same display as /GROUP.)

$ SHOW LOGICAL/TABLE=SYSTEM  SYS$LIBRARY
  "SYS$LIBRARY" = "SYS$SYSROOT:[SYSLIB]" (LNM$SYSTEM_TABLE) 
                = "DOCD$:[SYSC.SYSLIB]"

The SHOW LOGICAL command in this example displays the translation of the logical name SYS$LIBRARY in the system table. The response indicates that SYS$LIBRARY is defined in the system table, and that the logical name has two translations.

$ SHOW LOGICAL/TABLE=LNM$GROUP/TABLE=LNM$SYSTEM SYS$DISK
  "SYS$DISK" = "ZZZ3:" (LNM$SYSTEM_TABLE)

The SHOW LOGICAL command in this example is qualified by both the /TABLE=LNM$GROUP and /TABLE=LNM$SYSTEM qualifiers. The response indicates that the logical name SYS$DISK was found in the system logical name table. When you enter two conflicting qualifiers, as in this example, only the last qualifier you specify is used.

$ SHOW LOGICAL/TABLE=LNM$PROCESS_DIRECTORY

The SHOW LOGICAL command in this example displays the logical names in the process directory table. Each name is either a table name, or a name that translates iteratively to a table.

SHOW MEMORY

Displays the availability and usage of those system resources that are related to memory.

Format

SHOW MEMORY

PARAMETERS

None.

DESCRIPTION

The information provided by the SHOW MEMORY command can help you determine whether to change certain system memory resources to improve system performance. The system memory resources are as follows:

Physical memory
Process entry slots and balance slots
Nonpaged and paged dynamic memory
Space in paging and swapping files

When the SHOW MEMORY command is executed, a display is written to SYS$OUTPUT. Depending on which qualifiers you specify, the display shows the following memory resource statistics:

Physical memory usage
Bad page list
Number of pages allocated to an OpenVMS system
Slot usage
Dynamic memory usage (in bytes)
Paging file usage (in blocks)
Dynamic memory
Granularity hint regions for code and data (Alpha only)
Virtual I/O Cache facility (VAX only)

For a detailed description of each item displayed, see the examples.

QUALIFIERS

/ALL (default)
Displays all available information, that is, information displayed by the /FILES, /PHYSICAL_PAGES, /POOL, and /SLOTS qualifiers.
/CACHE
Displays information about the Virtual I/O Cache facility. The Cache facility information is displayed as part of the SHOW MEMORY and SHOW MEMORY/CACHE/FULL commands.
/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.
/FILES
Displays information about the use of each paging and swapping file currently installed.
/FULL
Displays additional information about each pool area or paging and swapping file currently installed, when used with the /POOL or the /FILES qualifier. This qualifier is ignored unless the /FILES or the /POOL qualifier is specified explicitly. When used with the /CACHE qualifier, /FULL displays additional information about the use of the Virtual I/O Cache facility.
/GH_REGIONS
On Alpha, displays information about the granularity hint regions (GHR) that have been established. For each of these regions, information is displayed about the size of the region, the amount of free memory, the amount of memory in use, and the amount of memory released from the region. The granularity hint regions information is also displayed as part of SHOW MEMORY, SHOW MEMORY/ALL, and SHOW MEMORY/FULL commands.
/HIGHLIGHT[=keyword]

/NOHIGHLIGHT (default)
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[=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.
