Variables include information that varies in system output (Internal error number), in command lines (/PRODUCER= name), and in command parameters in text (where dd represents the predefined code for the device type).

UPPERCASE TEXT Uppercase text indicates a command, the name of a routine, the name of a file, or the abbreviation for a system privilege.

Monospace text

Monospace type indicates code examples and interactive screen displays.

Chapter 1
Overview

The POLYCENTER Software Installation utility is a complete software installation and management tool for OpenVMS Alpha or VAX systems. It can package, install, remove, and manage software products on Alpha or VAX systems. It can also save information about software products such as system requirements and installation options.

The POLYCENTER Software Installation utility is intended for use both by those who create (package) kits for software products and by system managers who install and maintain these products. This guide describes how to package software products using the POLYCENTER Software Installation utility. It describes the product description language, product description files, product text files, and other relevant concepts.

System managers should refer to the OpenVMS System Manager's Manual for general use information.

1.1 Features for Software Providers

For software providers, the POLYCENTER Software Installation utility simplifies the task of packaging software because:

Installations require less packaging effort than most conventional installation methods. This results in performance gains and reduced development time over conventional installations.
You can include both brief and detailed installation text to guide users through an installation, resulting in a higher installation success rate.
Related products can easily be packaged as a product suite and installed in one operation.
The utility keeps track of which products (and versions) have been installed and removed in the execution environment. Using this information, you can design your installation procedure to check for and manage version dependencies.

1.2 Coexistence with VMSINSTAL

The POLYCENTER Software Installation utility is integrated into OpenVMS and coexists with the VMSINSTAL utility. Today, you use the POLYCENTER Software Installation utility to install the OpenVMS Operating System and some layered products on Alpha systems, and to install some layered products on VAX systems. The POLYCENTER Software Installation utility is the preferred installation mechanism for future layered product and OpenVMS releases.

The POLYCENTER Software Installation utility offers the following features:

Typically faster installation and upgrade operations
Removal (deinstallation) of previously installed software products
A database of information on installed products that has query capabilities on the database
Dependency checking of software products based on product version number

If you currently use VMSINSTAL to package your software product, see Appendix A for information about migrating from VMSINSTAL to the POLYCENTER Software Installation utility.

1.3 Creating an Installable Kit

As a software provider, you probably want to use the POLYCENTER Software Installation utility to create an installable kit for your software product. This kit might be a new software product or an update to an existing product; the POLYCENTER Software Installation utility has features for each case.

Your OpenVMS user will then be able to use the POLYCENTER Software Installation utility to install your product with a minimum of documentation and effort.

Generally, the installable kit you create will be packaged in one "container" file. This container file has the file extension .PCSI and is in the binary format recognized by the POLYCENTER Software Installation utility. The person installing your product will use the PRODUCT INSTALL command to install your kit on their OpenVMS system.

The sections that follow describe the main steps to create this installable .PCSI file.

1.3.1 Gather All of the Product Files

Locate all of the files to be included in the software product kit. These files are called the product material. These files can remain in the directories generated by the software engineering team, you can copy them to one or more staging directories, or you can copy them to a directory tree as they would appear after installation.

1.3.2 Plan Ahead

Determine the required characteristics of the execution environment for your product or platform. For example, you must determine where files will be placed, if DCL tables or help libraries need to be updated, if system or process parameters need to be checked, and if you need to provide any command procedures to perform product specific tasks.

1.3.3 Create a Product Description File

Create a product description file (PDF) with a text editor. This step is described in Chapter 3. PDF files:

Identify all of the files that the product provides
Can specify configuration choices the product offers, including default answers
Can specify product requirements (such as dependencies on other software products, minimum hardware configurations, and system parameter values)

PDF files use Product Description Language (PDL) statements (described in Chapter 7) to convey all of the information the POLYCENTER Software Installation utility needs for installing either a software product or a set of software products.

What does a PDF file look like? Example 1-1 shows a sample product description file. Subsequent chapters describe the PDF statements in line-by-line detail.

Example 1-1 PDF For an Application Software Kit

product DEC VAXVMS TNT V3.0 full ; if (not <software DEC VAXVMS VMS version minimum V6.2>) ; error NOVMS ; end if ; execute install "@PCSI$SOURCE:[SYSUPD]TNT$BACKUP.COM" remove "" -- nothing special to do on remove uses [SYSUPD]TNT$BACKUP.COM ; -- will not leave file on system execute start "@PCSI$DESTINATION:[SYS$STARTUP]TNT$STARTUP.COM" stop "@PCSI$DESTINATION:[SYS$STARTUP]TNT$SHUTDOWN.COM" ; execute test "@PCSI$DESTINATION:[SYSTEST]TNT$IVP.COM" ; directory [SYSTEST.TNT] ; directory [TNT] ; file [SYSHLP]TNT030.RELEASE_NOTES generation 50084697 release notes ; remove ; file [SYSHLP]TNT010.RELEASE_NOTES ; file [SYSHLP]TNT015.RELEASE_NOTES ; file [SYSHLP]TNT020.RELEASE_NOTES ; file [SYSHLP]TNT021.RELEASE_NOTES ; file [SYSEXE]TNT$POPULATE.EXE ; file [SYSEXE]TNT$INITJOURNAL.EXE ; file [SYSEXE]TNT$DUMPACS.EXE ; file [SYSEXE]TNT$DUMPJOURNAL.EXE ; end remove ; information RELEASE_NOTES phase after ; information POST_INSTALL phase after ; file [SYS$STARTUP]TNT$STARTUP.COM generation 50084697 ; file [SYS$STARTUP]TNT$SHUTDOWN.COM generation 50084697 ; file [SYSMGR]TNT$UTILITY.COM generation 50084697 ; file [SYSTEST]TNT$IVP.COM generation 50084697 ; file [SYSEXE]TNT$SERVER.EXE generation 50084697 ; file [SYSEXE]TNT$HELPER.EXE generation 50084697 ; file [SYSEXE]TNT$UTILITY.EXE generation 50084697 ; file [SYSEXE]TNT$EXCLUDED_SYMBIONTS.DAT generation 50084697 ; file [SYSTEST.TNT]TNT$SERVER_IVP.EXE generation 50084697 ; execute postinstall "@PCSI$DESTINATION:[SYSMGR]TNT$UTILITY.COM UPDATE ALL" ; end product ;

1.3.4 Optionally, Create a Product Text File

Create a product text file (PTF). This optional step is described in Chapter 4. The PTF provides information about the product in brief and detailed formats. The information includes product identification, copyright notice, configuration choice descriptions, and message text used primarily during product installation and configuration operations.

What does a PTF file look like? The PTF file format is similar to that of modules used with the Librarian utility (LIBRARY) to create, modify, or describe a help library.

Example 1-2 shows a product text file.

1.3.5 Package the Software Components

You package the software components to actually create the .PCSI file. This step is described in Chapter 5. You use the PRODUCT PACKAGE command and its various qualifiers to do this. This command determines if the PDF and PTF are syntactically correct and verifies that all listed product material files can be found.

1.3.6 Test and Debug the Installable Kit

Once a kit has been successfully produced, use the PRODUCT INSTALL, PRODUCT SHOW, and PRODUCT REMOVE commands to verify the installation and removal of the product. Check for correct file placement and protection, test user input, review message text, modify configuration options, verify that execution environment requirements are satisfied, and so forth.

You should test your installable kit to make sure that it properly handles any software version dependencies.
