Catalog Data – Keys to the Kingdom

The z/OS catalog is the backbone of dataset management, serving as the central source of truth for where data resides and how it’s defined. Each catalog entry holds vital details—such as dataset location, encryption keylabels, data formats, and expiration dates—that help ensure security, efficiency, and compliance.

In this webinar, we’ll break down how the catalog works, what information it maintains, and what catalog entries look like in practice. You’ll learn about the tools available to search and display catalog data, along with techniques for extracting key information. We’ll also demonstrate how to quickly retrieve dataset names, volumes, and attributes using REXX execs with the Catalog Search Interface and other programs—giving you practical skills to streamline your catalog operations.
