High availability and scalability
Continuous availability is a key quality of the z/OS operating environment. In this chapter, we start by providing an introduction to high availability and the technologies applicable to the z/OS operating environment. Then for each of the CICS access technologies, we discuss the best approach for optimizing the availability of the solution, and the resulting implications on the scalability of the system.
These are the key questions that we consider for each solution:
•What are the benefits of a high-availability ...
