Technical Information Checklists

To complete the checklists in this chapter, you use options from the z/OS Technical Information Menu. You access this menu by selecting option 3 from the Primary Menu.

The audit tests described in these checklists analyze the internal control blocks and tables of z/OS. The checklists are used as follows:

z/OS Subsystems

Review the z/OS subsystems in place on the system and their integrity.

User I/O Appendages

Review user‑written routines that control I/O operations.

z/OS System Exits

Review programs that systems programmers have added to z/OS.

Link Pack Area Analysis

Review the integrity of LPA libraries.

Fixed and Modified LPA

Review the controls in effect for the FLPA and MLPA libraries.

Program Properties Table (PPT)

Determine which programs are endowed with special powers by their presence in the PPT.

Supervisor Call Analysis

Document and review the use of the supervisor call (SVC) machine instruction, which programs use to communicate their needs for z/OS services to the operating system.

Use the W/P Ref column on these checklists to record a cross‑reference to the work paper that documents your findings about the aspect of z/OS that the checklist analyzes.
