Installation Choices Review

Once you obtain an overall view of the system you are about to review, you must become more familiar with the components of the z/OS operating system. The next area for review is the software choices that determine how the system runs and how secure the system actually is.

This chapter provides you with the concerns to consider while reviewing the System Installation Choices menu options:

• Structure and use of the system logical Parmlib parameter library (also known as just parmlib)
• Importance of the authorized program facility (APF), the powers it grants, and how APF authorization can be obtained
• Importance of using the system modification program (SMP/E), the importance of the consolidated software inventory (CSI), and how its integrity can be compromised
• Importance of analyzing the key system libraries, such as the APF and link pack area (LPA) libraries
• Information on TSO and the system catalogs
