The System Overview Display (1.1) provides basic, high‑level information about the computer system that you are reviewing. This display shows the type of central processing unit (CPU) and its serial number, the date and time of the last initial program load (IPL), and the release of z/OS in use.
The System Overview Display contains the central processing unit (CPU) type and serial numbers. Some plug‑compatible manufacturer (PCM) vendors (Amdahl, for example) present their own model numbers. Others appear as an equivalent IBM processor. If a CPU model (such as 2064) is available, CA Auditor displays that too, letting you further verify your billing information. CA Auditor also recognizes whether your z/OS system is running as a guest under VM.
CA Auditor also displays the six‑digit serial numbers of each processor in your system. These can be useful in verifying billing information.
The release of z/OS shown should be reasonably current. This usually means staying from four to six months behind the most recent release of the operating system. This avoids installing the latest operating system release before knowing if it has major problems. On the other hand, it is not wise to be too far behind the current release. Staying reasonably current reduces exposure to system problems and positions the data center to benefit from hardware improvements.
