A Practical Guide to ICF Catalogs

Book Description

This IBM® Redbooks® publication gives a broad understanding of integrated catalog facility (ICF) catalog environments. It includes suggestions for design, planning, and deployment tasks to help you create and maintain a balanced and efficient catalog environment.

Four scenarios are provided to illustrate sample implementations of typical activities that are associated with an organization’s requirements.

Chapter 5, “Record-level sharing support for ICF catalogs” describes Record Level Sharing (RLS) for Catalogs and shows the results of our tests in a controlled laboratory environment.

This version of the book is set at the IBM z/OS V2R2 level.

This publication is for readers who want to gain an understanding of ICF catalogs and the considerations and practices that surround an ICF catalog environment deployment.
