Abstract for New Function Summary
Purpose of this information: The purpose of this document is to describe the exploitation considerations of the new functions for the TCP/IP and SNA components of z/OS® Version 2 Release 2 Communications Server (z/OS Communications Server). It also includes the exploitation considerations of z/OS V2R1 Communications Server.
Who should read this information: This document is designed for planners, system 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/OSUNIX services even for traditional MVS™ environments and applications. Therefore, before using TCP/IP services, your installation must establish a full-function mode z/OSUNIX environment—including a Data Facility Storage Management Subsystem (DFSMSdfp), a hierarchical file system, and a security product (such as Resource Access Control Facility, or RACF®)—before z/OS Communications Server can be started successfully. Refer to z/OS UNIX System Services Planning for more information.
Conventions and terminology that are used in this information
- When describing how to use the command in a TSO environment, the command is presented in uppercase (for example, NETSTAT).
- When describing how to use the command in a z/OS UNIX environment, the command is presented in bold lowercase (for example, netstat).
- When referring to the command in a general way in text, the command is presented with an initial capital letter (for example, Netstat).
All the exit routines described in this information are installation-wide exit routines. The installation-wide exit routines also called installation-wide exits, exit routines, and exits throughout this information.
The TPF logon manager, although included with VTAM®, is an application program; therefore, the logon manager is documented separately from VTAM.
Samples used in this information might not be updated for each release. Evaluate a sample carefully before applying it to your system.
- RDMA network interface card (RNIC), which is used to refer to the IBM® 10 GbE RoCE Express® feature.
- Shared RoCE environment, which means that the 10 GbE RoCE Express feature operates on an IBM z13™ (z13) or later system, and that the feature can be used concurrently, or shared, by multiple operating system instances. The RoCE Express feature is considered to operate in a shared RoCE environment even if you use it with a single operating system instance.
For definitions of the terms and abbreviations that are used in this information, you can view the latest IBM terminology at the IBM Terminology website.
