6 Parallel Sysplex Quiz

T or F. Only the z/OS operating system contains Parallel Sysplex function. The middleware (such as data managers, networking, transaction managers, etc) do not have Parallel Sysplex functions and features.

False

T or F. Accessible to all servers in the Parallel Sysplex so that any unit of work can be run anywhere in the Parallel Sysplex

True

T or F: The Coupling Facility Control Code (CFCC) always runs in a logical partition (LPAR)

True

Most Parallel Sysplex configurations have at least two links between a server and a CF. Why two links and not just one?

better availability

The computer science term that best describes a Parallel Sysplex is

cluster

The reason most enterprises implement a Parallel Sysplex is

improved availability

Which Parallel Sysplex CF link technology would you use if your new Parallel Sysplex was spread out over a campus instead of being in a single machine room?

isc links

What operating system (besides z/OS) can actively participate in a Parallel Sysplex as a peer (e.g. use the CF to send messages) with one or more other z/OS operating system images?

no other operating systems

A data area in a CF is referred to as a

structure

The Parallel Sysplex hardware element that is responsible for synchronizing the time of day clocks on the servers in a Parallel Sysplex is:

sysplex Timer

The z/OS components responsible for directly managing z/OS to CF interactions is

xcf and xes

What is the difference between an external coupling facility (CF) and and internal CF?

CF is less expensive
