3.5 Kit Types and Usage

The POLYCENTER Software Installation utility supports seven kit types that can be grouped into three broad categories:

Primary kit --- Used to install or upgrade a product. Primary kits can require prerequisite products to be installed before or concurrently. Kit types in this category include:
- Full (layered product or application software)
- Operating system
- Platform (product suite)
Secondary kit --- Used to modify installed products. Kits types in this category include:
- Partial (changes the product's version)
- Patch (maintenance update)
- Mandatory update
Transition kit --- Used to register a product that has been installed using VMSINSTAL or some method other than the DCL command PRODUCT INSTALL. The kit type in this category is as follows:
- Transition

Use the PRODUCT PACKAGE command to package (or build) a product kit. The output of the packaging process is an installable kit (in either sequential copy format or reference format) that contains:

Product material (usually present) --- The files that make up the product. Usually, the installation of a product kit copies files to the target disk. However, there are exceptions:
- A transition kit never provides files.
- A platform kit references other products; it may or may not provide common files for the product suite.
- Since product material is not a requirement for any type of kit, you may create "skeleton" kits for testing purposes that do not modify the target disk.
A product description file (required) that drives the installation process --- It defines the managed objects that are provided or created and contains directives for the installation utility. In addition, it can include options for the installer to select, declare software references to other prerequisite products, and invoke command procedures you write to augment the installation process.
A product text file (optional) that provides text modules for use during the installation process.
Temporary files such as command procedures (optional) that are used during the installation process but are not left on the user's system.

The full product name (that is, the string producer-base-product) must be unique among all products installed on a system. This implies, for example, that there could be two FORTRAN compilers installed from different companies (such as DEC-AXPVMS-FORTRAN and XYZCORP-AXPVMS-FORTRAN), but there cannot be two patch kits with the same full name that are intended to apply to different products (such as ABC-AXPVMS-ECO1 for ABC-AXPVMS-COBOL and ABC-AXPVMS-ECO1 for ABC-AXPVMS-C).

The following sections describe each type of kit and provide examples of their product description files.

3.5.1 The Full Kit Type

A full kit provides layered product application software and is the most common type of kit. The PDF for a full kit must contain a PRODUCT statement with the keyword full and an END PRODUCT statement, as shown in the following example:

product CPQ AXPVMS TEST_A V2.0 full ;
   .
   .
   .
end product ;

The full kit has the following characteristics:

It contains all of the material for the product. Therefore, it can be used to install the product for the first time or it can upgrade a previously installed version of the product.
The product can be removed, configured, or reconfigured.
Its PDF can contain OPTION and SOFTWARE statements.

Example 3-1 shows a full kit that references another product.

Example 3-1 PDF for a Full Kit That References Another Full Kit

product HP AXPVMS FORTRAN V7.1-1 full ; (1)
    if (not <software HP AXPVMS VMS version minimum V7.1>) ;(2)
        software HP AXPVMS FORRTL version minimum V7.1 ;
    end if ;
    information STARTUP_TASK phase after ;
    information RELEASE_NOTES phase after ;(3)
    file [SYSHLP]FORTRAN.RELEASE_NOTES release notes ;(4)
    file [SYSHLP]FORTRAN_RELEASE_NOTES.PS ;
    file [SYSHLP]FORTRAN_RELEASE_NOTES.DECW$BOOK ;
    if (<software DEC AXPVMS FORTRAN90>) ;(5)
        error REMFORT90 ;
    end if ;
    option FORTRAN_90 ;(6)
        file [SYSEXE]F90$MAIN.EXE generation 2 ;
        file [SYSMSG]F90$MSG.EXE generation 2 ;
        module [000000]F90CLD.CLD type command generation 2 module F90 ;
        module [000000]F90HELP.HLP type help generation 2 module F90 ;(7)
    end option ;
    option FORTRAN_77 ;

        file [SYSEXE]FORT$FSPLIT.EXE generation 1 ;
        file [SYSMSG]FORT$MSG.EXE generation 1 ;
        file [SYSMSG]FORT$MSG2.EXE generation 1 ;
        module [000000]DEC_FORTCLD.CLD type command
            generation 1 module FORTRAN ;
        module [000000]DEC_FORHELP.HLP type help
            generation 1 module FORTRAN ;
    end option ;
    file [SYSLIB]FORSYSDEF.TLB generation 5 ;
    file [SYS$STARTUP]FORT$STARTUP.COM generation 1 protection private ;(8)
    file [SYSTEST]FORT$IVP.COM generation 1 protection private ;
    execute test "@PCSI$DESTINATION:[SYSTEST]FORT$IVP.COM" ;(9)
end product ;

The PRODUCT statement identifies this as a complete layered product kit for installation of (or upgrade to) FORTRAN V7.1-1 on an OpenVMS Alpha system.
The IF...END IF group conditionally executes statements within the group based on the evaluation of the IF function. In this example, the SOFTWARE statement is executed only if the system is running a version of OpenVMS earlier than V7.1. This SOFTWARE statement creates a software reference to the product FORRTL. If FORRTL V7.1 or later is already installed, the software dependency is satisfied; otherwise, FORRTL is automatically installed concurrently with FORTRAN.
This INFORMATION statement causes a message to be displayed after the product has been installed. Text is obtained from the module RELEASE_NOTES in the PTF:
1 RELEASE_NOTES =prompt Type HELP FORTRAN Release_notes for release notes location
This FILE statement copies file FORTRAN.RELEASE_NOTES to SYS$SYSDEVICE:[VMS$COMMON.][SYSHLP] (the same as SYS$COMMON:[SYSHLP]) unless the user specifies a different destination. The RELEASE NOTES keyword phrase tags this file in the kit so that the PRODUCT EXTRACT RELEASE_NOTES command can be used to extract this file from the kit.

This IF statement determines whether or not the product FORTRAN90 is installed. If it is installed, text from the module REMFORT90 in the PTF is displayed and the user is asked if he wants to terminate the operation:

    1 REMFORT90
    =prompt PRODUCT REMOVE FORTRAN90 before installing HP Fortran
    The obsolete DEC Fortran 90 product must be removed before HP Fortran
    is installed.  To do this, use the command:

       PRODUCT REMOVE FORTRAN90

Note that if the ABORT keyword had been used on the ERROR statement, the operation would terminate unconditionally. ABORT was not used because the ABORT keyword was introduced in OpenVMS V7.1 and this kit can be installed on earlier versions of OpenVMS.

This OPTION...END OPTION group conditionally provides files and library modules associated with the FORTRAN 90 compiler. The user is asked a question from text module FORTRAN_90 in the PTF:
1 FORTRAN_90 =prompt Compaq Fortran 90 compiler This option selects the Compaq Fortran 90 compiler.
By default, the OPTION statement displays only text from the prompt line. However, if the user specifies the /HELP qualifier on the PRODUCT INSTALL command, then both prompt and extended help text is displayed (two lines in this case).
The MODULE statement installs the help text module F90 from the file F90HELP.HLP in the default help library [SYSHLP]HELPLIB.HLB. The file F90HELP.HLP is not left on the system because a FILE statement is not used.
The PROTECTION PRIVATE keyword phrase on this FILE statement sets the file protection to (S:RWED, O:RWED, G, W), giving general users no access.
The EXECUTE TEST statement executes the functional test for the product (the installation verification procedure) after the product has been installed. If the test fails, the user is informed but the product is not removed. The user can use the PRODUCT REMOVE command to delete the product.
