Abstract for SNA Resource Definition Samples

Purpose of this information

This information contains sample definitions to help system programmers define resources in a VTAM® network.

Requirement

Be aware that these samples are for illustrative purposes only; they are not intended to run in your network as presented here. You must make the proper modifications to the samples for your specific installation. For example, operands that define such items as line speed and control unit addresses must be changed to match the needs of your installation.

Who should read this information:

This information is intended for anyone that is planning to define resources in a VTAM network.

Conventions and terminology that are used in this information

Commands in this information that can be used in both TSO and z/OS® UNIX environments use the following conventions:
  • 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.

Note: In this information, you might see the following Shared Memory Communications over Remote Direct Memory Access (SMC-R) terminology:
  • RoCE Express®, which is a generic term representing IBM® 10 GbE RoCE Express, IBM 10 GbE RoCE Express2, and IBM 25 GbE RoCE Express2 feature capabilities. When this term is used in this information, the processing being described applies to both features. If processing is applicable to only one feature, the full terminology, for instance, IBM 10 GbE RoCE Express will be used.
  • RoCE Express2, which is a generic term representing an IBM RoCE Express2® feature that might operate in either 10 GbE or 25 GbE link speed. When this term is used in this information, the processing being described applies to either link speed. If processing is applicable to only one link speed, the full terminology, for instance, IBM 25 GbE RoCE Express2 will be used.
  • RDMA network interface card (RNIC), which is used to refer to the IBM® 10 GbE RoCE Express, IBM® 10 GbE RoCE Express2, or IBM 25 GbE RoCE Express2 feature.
  • Shared RoCE environment, which means that the "RoCE Express" feature can be used concurrently, or shared, by multiple operating system instances. The feature is considered to operate in a shared RoCE environment even if you use it with a single operating system instance.
