The command in this example displays help information about the LIST command.

Displays a description of each specified known image or, if no file is specified, all known images.

Format

LIST [file-spec]

Parameter

file-spec

Names the file specification of an image installed as a known image. If you omit the file specification, INSTALL displays all known images.

Description

You can use the LIST command with the /FULL qualifier to display information that is useful in tuning the known image database. For example, a high entry-access count for an image may indicate that system performance could benefit if the image were installed /OPEN. Similarly, high entry-access counts for an image may indicate that installing the image /SHARED---that is, with global sections---could improve performance. For a description of global sections and global pages, including information about how to estimate the size of installed images, refer to the OpenVMS System Services Reference Manual.

Qualifiers

/FULL

Displays a multiline description of the specified known image, including the number of accesses, the number of concurrent accesses, and the number of global sections created. The /FULL qualifier with the /GLOBAL qualifier shows information about global sections, plus the current owner and protection codes and access control entries.

/GLOBAL

Lists global sections for any specified shared image, or if you omit the file specification, lists all global sections. If a global section is created by INSTALL to support a particular image, that image is also identified.

/RESIDENT

Displays a description of each resident image.

/STRUCTURE

Lists addresses of known image data structures.

/SUMMARY

Used with the /GLOBAL qualifier, displays the global section and global page usage on the system for local and shared memory global sections.

Examples

INSTALL> LIST
      

The command in this example displays a single-line description of all known images. The description includes the file specification of the known image and its attributes.

INSTALL> LIST/FULL LOGINOUT
      

The command in this example displays a multiline description of the known image LOGINOUT.

SYS$DISK:<SYS0.SYSCOMMON.SYSEXE>.EXE LOGINOUT;3 Open Hdr Shar Priv Entry access count = 44 (1) Current / Maximum shared = 3 / 5 (2) Global section count = 2 (3) Privileges = CMKRNL SYSNAM TMPMBX EXQUOTA SYSPRV (4)

1. Number of times known file entry has been accessed by this node since it swas installed.
2. First number indicates the current count of concurrent accesses of the known file. The second number indicates the highest count of concurrent accesses of the file since it was installed. This number appears only if the image is installed with the /OPEN qualifier.
3. Number of global sections created for the known file; appears only if the image is installed with the /SHARED qualifier.
4. Translation of the privilege mask; appears only if the image is installed with privileges.

INSTALL> LIST/GLOBAL
      

The command in this example displays all global sections for shared images. Global sections created by INSTALL (prefix INS$) for a specific image are listed following the name of that image.

System Global Sections (1) DSA1000:<SYS2.SYSCOMMON.SYSLIB>SLS$USSSHR.EXE (2) INS$86D9BFB0_003 (3) (14000001) (4) PRM SYS (5) Pagcnt/Refcnt=1/1 (6) INS$86D9BFB0_002 (14000001) PRM SYS Pagcnt/Refcnt=3/3 INS$86D9BFB0_001 (14000001) PRM SYS Pagcnt/Refcnt=1/1 . . .

1. Display of global sections in memory.
2. Name of the image for which the following global sections were created by INSTALL.
3. Name of global section. The prefix identifies the creator of the section; for example, INS means the global section was created by INSTALL. The number includes the address of the section.
4. Version number (in hexadecimal) of global section; for shareable images only, the high-order byte (01 in CRFSHR_003) contains major identification, and low-order bytes (0003E8 in CRFSHR_003) contain minor identification determined by the programmer at link time. For executable images, the number is a known unique value determined by the system.
5. Attributes of the global section:

   DZRO	Global section is demand-zero.
   GRP	Along with a group number indicates a groupwide section, which would be created by a program other than INSTALL.
   PRM	Global section is permanent.
   SYS	Global section is systemwide.
   TMP	Indicates a temporary global section, which would be created by a program other than INSTALL.
   WRT	Global section is writable.

6. Number of pages (VAX) or pagelets (Alpha) in the section and number of page table entries currently mapped to this global section. For a more detailed discussion of mapping global sections, refer to the OpenVMS Programming Concepts Manual.
7. Number of global sections created, number of global pages used, and number of global pages unused in local memory. Note that, because of arithmetic rounding, the number of global sections created will sometimes be greater than the SYSGEN parameter GBLSECTIONS. When the size of the system header is being computed, the values of the GBLSECTIONS and SYSMWCNT parameters are combined with the size of the fixed part of the process header. The result is rounded up to the next page boundary. This rounding process sometimes adds space to the global section table, depending on the values of the two SYSGEN parameters and the amount of system paging that preceded the running of INSTALL to create all of the global sections.

INSTALL> LIST/GLOBAL/FULL
      

The command in this example displays a complete listing of global sections for shared images. The /FULL qualifier adds owner and protection codes to the display.

System Global Sections NM_MAILSHR_003 (741A6919) PRM SYS Pagcnt/Refcnt=10/0 NM_MAILSHR_002 (741A6919) PRM SYS Pagcnt/Refcnt=1/0 NM_MAILSHR_001 (741A6919) PRM SYS Pagcnt/Refcnt=11/0 Owner: [1,4] (1) Protection: S:RWED,O:RWED,G:RWED,W:RE (2) . . .

1. UIC of the owner of the global section
2. Type of access allowed for the image

Deletes all known file entries for images installed without the /NOPURGE qualifier.

Requires the CMKRNL privilege. Also requires the SYSGBL privilege to create system global sections and the PRMGBL privilege to create permanent global sections.

Format

PURGE

Parameters

None.

Description

The PURGE command deletes all known file entries for images installed without the /NOPURGE qualifier.

If a process is accessing global sections when the PURGE command is entered, the global sections are deleted only after the operation initiated by the process completes. However, once the command is entered, no additional processes can access the global sections because they are marked for deletion.

Example

INSTALL> PURGE
      

The command in this example deletes all images except those installed with the /NOPURGE qualifier. The image files remain unaffected. Writable global sections are written back to disk upon their removal as known images.

Deletes a known image. The REMOVE command is identical to the DELETE command.

Requires the CMKRNL privilege. Also requires the SYSGBL privilege to create system global sections and the PRMGBL privilege to create permanent global sections.

Format

REMOVE file-spec

Parameter

file-spec

Names the file specification of a known image.

Description

The REMOVE command deletes an entry from the known file list. The image's entry on the known file list and any global sections created for the image are deleted. The image file remains unaffected. Writable global sections are written back to disk upon their removal as known images.

If a process is accessing global sections when the REMOVE command is entered, the global sections are deleted only after the operation initiated by the process completes. However, once the command is entered, no additional processes can access the global sections because they are marked for deletion.

Example

INSTALL> REMOVE GRPCOMM
      

The command in this example deletes the entry for the known image GRPCOMM from the known image file list.

Replaces a known image entry with another version of the image, or with modified attributes. The REPLACE command is a synonym for the DELETE command.

Requires the CMKRNL privilege. Also requires the SYSGBL privilege to create system global sections and the PRMGBL privilege to create permanent global sections.

Format

REPLACE file-spec

Parameter

file-spec

Names the file specification of an image installed as a known image.

Description

The REPLACE command updates a known file to the latest, or to a specified version found in the specified directory, or in another directory if the file-spec parameter uses a search list.

You can use the REPLACE command to modify the attributes of currently installed images. Either specify new qualifiers, or change the value of qualifiers used when installing the image with the CREATE (or ADD) command. If you specify no qualifiers, the new image retains the same attributes as the old one. If the REPLACE command modifies neither the installed image file nor its attributes, the REPLACE command allows continued sharing of global sections.

If a process is accessing global sections when the REPLACE command is entered, the global sections are deleted only after the operation initiated by the process completes. However, once the command is entered, no additional processes can access the global sections because they are marked for deletion.

Qualifiers

/ACCOUNTING

/NOACCOUNTING (default)

Enables image-level accounting for selected images even if image accounting is disabled on the local node (by using the DCL command SET ACCOUNTING/DISABLE=IMAGE). When image accounting is enabled on the local node, it logs all images, and the /NOACCOUNTING qualifier has no effect.

/EXECUTE_ONLY

/NOEXECUTE_ONLY (default)

The /EXECUTE_ONLY qualifier is meaningful only to main programs. It allows the image to activate shareable images to which the user has execute access but no read access. All shareable images referenced by the program must be installed, and OpenVMS RMS uses trusted logical names, those created for use in executive or kernel mode.

You cannot specify this qualifier for an executable image linked with the /TRACEBACK qualifier.

/HEADER_RESIDENT

/NOHEADER_RESIDENT

Installs the file as a known image with a permanently resident header (native mode images only). An image installed header resident is implicitly installed open.

/LOG

/NOLOG (default)

Lists the newly created known file entry along with any associated global sections created by the installation.

/OPEN

/NOOPEN

Installs the file as a permanently open known image.

/PRIVILEGED[=(priv-name[,...])]

/NOPRIVILEGED[=(priv-name[,...])]

Installs the file as a known image with the privileges specified. Then, if the image is not located on the system volume, the image is implicitly installed open.

The /PRIVILEGED qualifier applies only to executable images.

You cannot specify this qualifier for an executable image linked with the /TRACEBACK qualifier.

For a complete listing of privileges, see the table in the CREATE command section.

/PROTECTED

/NOPROTECTED (default)

Installs the file as a known image that is protected from user-mode and supervisor-mode write access. You can write into the image only from executive or kernel mode. The /PROTECTED qualifier together with the /SHARE qualifier are used to implement user-written services, which become privileged shareable images.

/PURGE (default)

/NOPURGE

Specifies that the image can be removed by a purge operation; if you specify /NOPURGE, you can remove the image only by a delete or remove operation.

/RESIDENT[=([NO]CODE,[NO]DATA)]

On Alpha systems, causes image code sections or read-only data sections to be placed in the granularity hint regions and compresses other image sections, which remain located in process space. If you do not specify the /RESIDENT qualifier, neither code nor data is installed resident. If you specify the /RESIDENT qualifier without keyword arguments, code is installed resident, and data is not installed resident.

The image must be linked using the /SECTION_BINDING=(CODE,DATA) qualifier. An image installed with resident code or data is implicitly installed /HEADER_RESIDENT and /SHARED.

/SHARED[=[NO]ADDRESS_DATA]

/NOSHARED

Installs the file as a shared known image and creates global sections for the image sections that can be shared. An image installed shared is implicitly installed open.

When you use the ADDRESS_DATA keyword with the /SHARED qualifier, P1 space addresses are assigned for shareable images. With the assigned addresses, the Install utility can determine the content of an address data section when the image is installed rather than when it is activated, reducing CPU and I/O time. A global section is created to allow shared access to address data image sections.

/WRITABLE

/NOWRITABLE

Installs the file as a writable known image as long as you also specify the /SHARED qualifier. The /WRITABLE qualifier only applies to images with image sections that are shareable and writable. The /WRITABLE qualifier is automatically negated if the /NOSHARED qualifier is specified.

Example

INSTALL> REPLACE GRPCOMM /ACCOUNTING/NOOPEN
      

The command in this example replaces the known image GRPCOMM with the latest version of the image, while enabling image accounting and removing the OPEN attribute from this version.

The full name of the file specification is assumed to be SYS$SYSTEM:GRPCOMM.EXE.
