HP OpenVMS System Management Utilities Reference
Manual
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.
You must have PFNMAP privilege to install the image with /RESIDENT
qualifier.
/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
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 |
INSTALL> HELP LIST
LIST
For display of a one-line description of the specified known image,
or if no file is specified, then for all known images. Use with
/FULL to obtain a multiline description.
Format: LIST [file-spec] /qualifier
QUALIFIER COMBINATION BEHAVIOR
LIST [file-spec] List the known image for file-spec
LIST List all entries
Additional information available:
Qualifiers
/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
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.

- Number of times known file entry has been
accessed by this node since it swas installed.
- 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.
- Number of global sections created for the
known file; appears only if the image is installed with the /SHARED
qualifier.
- Translation of the privilege mask; appears
only if the image is installed with privileges.
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.

- Display of global sections in memory.
- Name of the image for which the following
global sections were created by INSTALL.
- 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.
- 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.
- 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.
|
- Number of pages (VAX) or pagelets (Alpha and
Integrity servers) 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.
- 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.

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