Purpose of this information: The purpose of this information is to describe the exploitation considerations of the new functions for the TCP/IP and SNA components of z/OS® Version 1 Release 13 Communications Server (z/OS Communications Server). It also includes the exploitation considerations of z/OS V1R12 Communications Server.
Who should read this information: This information is designed for planners, systems programmers, and network administrators who are planning to install z/OS Communications Server and who want to learn more about its new and enhanced features.
Prerequisite and related information: z/OS Communications Server exploits z/OS UNIX services even for traditional MVS™ environments and applications. Therefore, before using TCP/IP services, your installation must establish a full-function mode z/OS UNIX environment—including a Data Facility Storage Management Subsystem (DFSMSdfp), a Hierarchical File System (HFS), and a security product (such as Resource Access Control Facility, or RACF®)—before z/OS Communications Server can be started successfully. See z/OS UNIX System Services Planning for more information.
