The following examples show several ways to define a CSI structure describing a sample z/OS® system with Job Entry Subsystem 3 (JES3) and an Information Management System (IMS™) subsystem. In some of the examples, a single CSI contains multiple zones. Others show zones that are separated into multiple CSI data sets. Zones in separate CSIs can be connected by a single global zone. The CSI that contains the global zone is called the master CSI.
