The CICSPlex® System Manager element of CICS® Transaction Server for z/OS®, Version 3 Release 1 (CICSPlex SM) is a system management tool that enables you to manage multiple CICS systems from a single control point. Enterprises in which CICSPlex SM may be needed range from those running 10 or 15 CICS systems, to those running two or three hundred (or more) CICS systems: in the latest MVS™ sysplex environment, having such large numbers of CICS systems to support a transaction-processing workload is becoming increasingly common.

Security checks that are usually performed by CICS (that is, CICS command checking and CICS resource checking) are performed instead by CICSPlex SM.

The CICSPlex SM environment provides an overview of the basic CICSPlex SM features and functions.
