Organization

This guide contains the following information:

Operating System Review

Contains checklists to plan your review. Use these checklists with the more specific function‑oriented checklists in later chapters.

Management Information

Provides checklists that analyze z/OS overview information. They analyze the system, hardware devices and errors, operator consoles, and the options that control system management facility (SMF) records.

System Installation Choices

Contains checklists to analyze the integrity of libraries. They review the system parameter library, APF‑authorized libraries, System Modification Program Extended (SMP/E), key system libraries, Time Sharing Option (TSO), and access controls that protect catalogs.

Technical Information

Contains checklists to analyze z/OS internal control blocks and tables. They analyze the z/OS subsystems, user I/O appendages, z/OS system exits, link pack area (LPA) libraries, fixed and modified LPA, program properties table (PPT), and supervisor calls (SVCs).

Job Processing Information

Provides checklists to analyze JES processing. Specifically, these checklists analyze JES2 and JES3 parameters, procedure libraries, job control language (JCL) libraries, and job‑related history records stored in SMF files or log streams.

Program Information

Includes checklists to analyze programs that z/OS process. They can help you analyze information about a program’s origin, execution history, or contents of program libraries. You can use these checklists to review exit load modules and production source modules, to detect and review changes to load and source modules, and to correlate source modules with load modules.

File Information

Provides checklists to analyze the way z/OS processes files. They analyze the integrity of the z/OS password system, load libraries, and VTOCs. They review the names and locations of z/OS libraries, analyze disk packs, and review the efficiency of change‑control practices. Other checklists let you review differences in applications or system data files or SMF records that journal access, and other operations.
