VMS Help INSTALL, REPLACE  *Conan The Librarian (sorry for the slow response - running on an old VAX)

    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

1 - Parameter

 file-spec

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

2 - Qualifiers

 2.1 - /ACCOUNTING

       /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.

 2.2 - /ARB_SUPPORT

       /ARB_SUPPORT=keyword

    On Alpha systems, overrides the system parameter ARB_SUPPORT for
    this installed image.

    The following table shows the keywords you can use with the /ARB_
    SUPPORT qualifier:

    Keyword     Behavior

    None        The obsolete kernel data cells are not maintained by
                the system. Fields are initialized to zero (or set to
                invalid pointers) at process creation.

    Clear       The obsolete kernel data cells are cleared (or set
                to invalid pointers) when the code would have set up
                values for backward compatibility.

    Read-only   The obsolete cells are updated with corresponding
                security information stored in the current Persona
                Security Block (PSB) when a $PERSONA_ASSUME is
                issued.

    Full        Data is moved from the obsolete cells to the
    (default)   currently active PSB on any security-based operation.

 2.3 - /AUTHPRIVILEGES

       /AUTHPRIVILEGES[=(priv-name[,...])]
       /NOAUTHPRIVILEGES

    Installs the file as a known image installed with the authorized
    privileges specified.

    Usage Notes

    o  If a privileged image is not located on the system volume, the
       image is implicitly installed /OPEN.

    o  The set of privileges for a privileged image can be empty. You
       must, however, list each privilege every time you define or
       redefine privileges.

    o  The /AUTHPRIVILEGES qualifier applies only to executable
       images.

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

    Interaction of /PRIVILEGED and /AUTHPRIVILEGES Qualifiers

    When you REPLACE an image, any privileges assigned with the
    /PRIVILEGED qualifier are not repeated as authorized privileges.
    Also, if you use the REPLACE command with the /NOAUTHPRIVILEGES
    qualifier, the authorized privileges listed are the same as
    the Default Privileges (set using the /PRIVILEGED qualifier).
    If you do not want this default behavior, you can specify
    /AUTHPRIVILEGES=NOALL, which will assign no authorized privileges
    to the image.

    Valid qualifiers are described in detail in an appendix of the
    OpenVMS Guide to System Security.

 2.4 - /EXECUTE_ONLY

       /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.

 2.5 - /HEADER_RESIDENT

       /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.

 2.6 - /LOG

       /LOG
       /NOLOG (default)

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

 2.7 - /OPEN

       /OPEN
       /NOOPEN

    Installs the file as a permanently open known image.

 2.8 - /PRIVILEGED

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

    Installs the file as a known image installed with the working
    privileges specified.

    Usage Notes

    o  If a privileged image is not located on the system volume, the
       image is implicitly installed /OPEN.

    o  The set of privileges for a privileged image can be empty. You
       must, however, list each privilege every time you define or
       redefine privileges.

    o  The /PRIVILEGED qualifier applies only to executable images.

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

    Valid qualifiers are described in detail in an appendix of the
    OpenVMS Guide to System Security.

 2.9 - /PROTECTED

       /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.

 2.10 - /PURGE

       /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.

 2.11 - /RESIDENT

       /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.

 2.12 - /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.

 2.13 - /WRITABLE

       /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.

3 - 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.
