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=[GALAXY[=IDENT]]

/NOWRITABLE

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

You can use the GALAXY keyword with the /WRITABLE qualifier to place write shared image sections in Galaxy global sections. You can also use the IDENT keyword with GALAXY to include the image ident in the name of the Galaxy global section, so that multiple versions of an image can be used simultaneously in a Galaxy system.

Examples

#1 

INSTALL> CREATE/OPEN/SHARED WRKD$:[MAIN]STATSHR

The command in this example installs the image file STATSHR as a permanently open shared known image.

#2 

INSTALL> CREATE/OPEN/PRIVILEGED=(GROUP,GRPNAM) GRPCOMM

The command in this example installs the image file GRPCOMM as a permanently open known image with the privileges GROUP and GRPNAM.

Any process running GRPCOMM receives the GROUP and GRPNAM privileges for the duration of the execution of GRPCOMM. The full name of GRPCOMM is assumed to be SYS$SYSTEM:GRPCOMM.EXE.

#3 

INSTALL> CREATE/LOG GRPCOMM

The command in this example installs the image file GRPCOMM as a known image and then displays the newly created known file entry.

#4 

INSTALL> CREATE/SHARED=ADDRESS_DATA WRKD$:[MAIN]INFOSHR

The command in this example installs the INFOSHR file as a shared known image and creates shared global sections for code sections and read-only data sections. Because the command includes the ADDRESS_DATA keyword, address data is also created as a shared global section.

#5 

INSTALL> CREATE STATSHR/PRIV

The command in this example creates the STATSHR image with all privileges.

#6 

INSTALL> CREATE STATSHR/PRIV=(OPER,SYSPRV)

The command in this example creates the STATSHR image with the OPER and SYSPRV privileges.

#7 

INSTALL> CREATE STATSHR/PRIV=NOALL

The command in this example creates the STATSHR image with an empty set of privileges.

#8 

INSTALL> CREATE STATSHR/NOPRIV

The command in this example creates the STATSHR image explicitly with no privileges.

DELETE

Deletes a known image. The DELETE command is a synonym for the REMOVE command.

EXIT

Terminates INSTALL and returns control to the DCL command level. You can also exit from INSTALL by pressing Ctrl/Z.

Format

EXIT

HELP

Displays information about how to use INSTALL.

Format

HELP [command]

Parameter

command

Specifies the name of a command for which help infomation is to be displayed. If you omit a command name, a list of commands is displayed and you are prompted for a command name.

Examples

#1 

INSTALL> HELP

The command in this example displays a list of INSTALL topics and a Topic? prompt. Any topic from the list can be entered at the prompt.

#2

  /FULL      /GLOBAL    /STRUCTURE    /SUMMARY

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

LIST

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, see the HP 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

#1 

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.

 671 Global Sections Used, 102138/22862  Global Pages Used/Unused (7)

  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 and I64) in the section and number of page table entries currently mapped to this global section. For a more detailed discussion of mapping global sections, see the HP 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.

PURGE

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.

REMOVE

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.
