version below version |
version maximum version |
version minimum version |
version required version |
version above version version below version |
version above version version maximum version |
version minimum version version below version |
version minimum version version maximum version } ;

Function Syntax

< upgrade
{ version above version |

version maximum version |
version minimum version |
version required version |
version above version version below version |
version above version version maximum version |
version minimum version version below version |
version minimum version version maximum version } >

Options

version above version

Indicates an invalid product version. Use this option to specify that the product version must be more than (but not equal to) the specified version. You cannot use this option with either the version minimum or version required options. By default, there is no largest invalid version.

version below version

Indicates the smallest invalid product version. Use this option to specify that the product version must be less than (but not equal to) the specified version. You cannot use this option with either the version maximum or version required options. By default, there is no smallest invalid version.

version maximum version

Indicates a maximum product version that must be available. Use this option to specify that the product version must be less than or equal to the specified version. You cannot use this option with either the version below or version required options. By default, there is no maximum version.

version minimum version

Indicates a minimum product version that must be available. Use this option to specify that the product version must be greater than or equal to the specified version. You cannot use this option with the version required or version above options. By default, there is no minimum version.

version required version

Indicates a required product version that must be available. Use this option to specify that a specific product version must be present. You cannot use this option with either the version above, version below, version maximum, or version minimum options. By default, there is no required version.

Description

Statement

In a full, operating system, or platform PDF, the upgrade statement specifies which product versions must be available for a successful product upgrade. If there is no available version of the product installed, the utility ignores the upgrade statement and performs a new installation. If the upgrade statement is not present, there is no constraint on the available version of the product.

In a partial PDF, the upgrade statement is required to specify which product versions must be available for the partial kit to be applied successfully.

Function

The upgrade function tests whether a version of the product is available. If a version of the product is available, the function returns true. If a version of the product is not available, the function returns false.

Example

product DEC VAXVMS ABC V5.5-2 partial ; 
    upgrade version minimum V5.5 version maximum V5.5-2 ; 
   .
   .
   .
end product; 
      

The upgrade statement in this example specifies that to install ABC Version 5.5--2, your system must be running at least ABC Version 5.5 and no higher than ABC Version 5.5--2.

VMSINSTAL is an installation mechanism supplied by Compaq. This appendix contains information about VMSINSTAL options and callbacks and their POLYCENTER Software Installation utility equivalents.

A.1 VMSINSTAL Options and Equivalents

Table A-1 lists some tasks that you may need to perform, the corresponding VMSINSTAL option, and the POLYCENTER Software Installation utility equivalent. Note that some VMSINSTAL options do not have an equivalent. In many cases, this is because the design of the POLYCENTER Software Installation utility eliminates the need for an equivalent.

Table A-1 VMSINSTAL Options and Equivalents

Task	VMSINSTAL Option	POLYCENTER Software Installation Utility Equivalent
Creating a file that specifies answers to installation questions	OPTIONS A	Create a product configuration file (PCF). This is similar to an auto-answer file in VMSINSTAL.
Specifying a temporary work directory	OPTIONS AWD	Specify the /WORK qualifier to the PRODUCT command.
Startup	OPTIONS B 1	No equivalent.
Tracing callbacks during installation	OPTIONS C 2	Use the /LOG and /TRACE qualifiers to the PRODUCT command. You can also use the /NOCOPY qualifier when debugging a product description file (PDF) to prevent the product material from being copied into the reference copy.
Manipulating product kits	OPTIONS G	Use the COPY/FORMAT=REFERENCE and COPY/FORMAT=SEQUENTIAL commands to manipulate product kits (see Chapter 5).
Suppressing VMSINSTAL prompts	OPTIONS I 2	No equivalent.
Debugging a kit	OPTIONS K 2	Use the /LOG and /TRACE qualifiers to assist in debugging a PDF.
Providing a log of installation operations	OPTIONS L	Use the /LOG and /TRACE qualifiers. This provides more information than OPTIONS L with VMSINSTAL.
Displaying or printing release notes	OPTIONS N	Use the release notes option to the file statement and the PRODUCT EXTRACT RELEASE_NOTES command. The release notes are created in the file DEFAULT.PCSI$RELEASE_NOTES in the current directory.
Performing an installation in test mode	OPTIONS Q 2	No equivalent.
Installing a product in an alternate root	OPTIONS R	Use the /DESTINATION qualifier.
Pausing the installation at various points	OPTIONS RSP 2	No equivalent.
Compiling information about the installation	OPTIONS S 2	Use the /LOG and /TRACE qualifiers to the PRODUCT command.

To install a product using VMSINSTAL, you create a command procedure named KITINSTAL.COM that makes callbacks to VMSINSTAL. If you are migrating from VMSINSTAL to the POLYCENTER Software Installation utility, refer to Table A-2, which lists the VMSINSTAL callbacks and their equivalents.

Table A-2 VMSINSTAL Callbacks and Equivalents

Task	VMSINSTAL Callback	Option	POLYCENTER Software Installation Utility Equivalent

Returning input in uppercase		U	No equivalent.
Indicating the response can be Ctrl/Z		A	No equivalent.
Determining whether a license for the product is installed on the system	CHECK_LICENSE		No equivalent. License management is outside the domain of the utility.
Determining whether the network is running	CHECK_NETWORK		No equivalent. If you use a statement that references the DECnet network, the utility ensures that the network is available.
Determining whether there is sufficient disk space on the target device	CHECK_NET_UTILIZATION		No equivalent. The utility ensures that sufficient disk space is available.
Determining whether a minimum version of software is present in the execution environment	CHECK_PRODUCT_VERSION		Use the version minimum option to the software function.
Limiting an installation to specified versions of the OpenVMS operating system	CHECK_VMS_VERSION		Use the version minimum and version maximum options to the software function, specifying DEC as the producer name, VAXVMS or AXPVMS as the base, and VMS as the product name.
Determining which is the most recent version of an image	COMPARE_IMAGE		You can manage file versions using the generation option to the file statement.
Determining whether the user has loaded the license for the product being installed on the system	CONFIRM_LICENSE		No equivalent. License management is outside the domain of the utility.
