134 CICS Transaction Gateway V5
The following sections detail the software levels we used in our sample
configuration and instructions on how we installed the CICS TG for z/OS.
The communication protocol from the CICS TG for z/OS to the z/OS CICS region
is External CICS Interface (EXCI). Because EXCI is complex enough to warrant
its own chapter, we suggest you become familiar with Chapter 4, “EXCI
connections to CICS” on page 65.

The CICS TG for z/OS runs in the z/OS UNIX System Services environment. As
such, you will need a mix of traditional MVS skills and UNIX skills in order to
install and to configure it. In this chapter, we introduce the CICS TG and the
UNIX System Services environment from the point of view of a CICS systems
programmer with MVS skills who wishes to administer the CICS TG for z/OS.
