Chapter 28: Information Storage Format in Database and Configuration Files

This chapter introduces the files UPS uses for product management. It also describes the format of the information storage in these files, which is in the format of KEYWORD=VALUE pairs. The supported keywords are listed and described.

Chapter 29: Version Files

Version files are UPS database files that contain information specific to the local installation and declaration of the declared product instances. The contents of version files are described in this chapter.

Chapter 30: Chain Files

UPS/UPD supports chains to product versions, and chain information is maintained in chain files. In this chapter we describe chain files and how they interact with version files.

Chapter 31: The UPS Configuration File

A UPS database can be configured and customized using the file dbconfig, described in this chapter. It is used to define keywords which control quantities such as:

• which nodes can access products maintained in the database
• the directory under which products are installed
• which products will have usage statistics collected
• the directories for product man pages and Info files
• the directory containing the UPS initialization files
• the directory containing the UPD configuration file
• the UPS database version

Chapter 32: The UPD Configuration File

UPD can be configured and customized on your system using the file updconfig, described in this chapter. By providing default values for several variables (mostly product file and directory locations), the updconfig file controls where UPD installs products and miscellaneous product-related files. It can also be used to define supplementary actions for UPD to perform when installing or updating products.

Chapter 33: The UPP Subscription File

UPP is a layer on top of UPD that can be used to facilitate the update of products on a local UPS node as new versions become available on a product distribution node. UPP is configured on the local node by subscription files, which we describe in this chapter. The functions UPP can be configured to perform on a local node include:

• notify the client of new and updated products on a specified distribution node
• perform product installations and updates
• install/update product dependencies and resolve chains to maintain integrity of main product
• delete old product versions
