Purpose of this information
This document is intended to help network operators use VTAM® commands and messages to control and maintain a telecommunication network. It contains descriptions of VTAM commands. The information in this document includes descriptions of support for both IPv6 and IPv4 networking protocols. Unless explicitly noted, descriptions of IP protocol support concern IPv4. IPv6 support is qualified within the text.
You can use this document as a reference for specific operator commands and as background reading to help understand how to operate VTAM.
Who should read this information
This document is primarily a reference for network operators. It also contains introductory material intended for a new operator. The system programmer can use this document as a reference about command syntax and function to write a local operating procedure.
To make the best use of this document, both the operator and the system programmer should be familiar with the local operating system.
As a VTAM operator, you should have background knowledge of VTAM as well as a background knowledge of network programs offered by IBM. Information in System Network Architecture Technical Overview might also be of use to a new operator.
A more experienced operator might want to consult z/OS Communications Server: SNA Network Implementation Guide.
A system programmer preparing a local operating procedure should know how to plan a VTAM installation, include VTAM in an MVS™ operating system, and define a VTAM domain. A prerequisite publication for system programmers who use this document is z/OS Communications Server: SNA Network Implementation Guide.
How this information is organized
This document is organized into the following information:
- Introducing an operator to VTAM provides an overview of how an operator controls VTAM.
- The following topics contain VTAM operator
command descriptions and the syntax required to enter these commands.
The description of each command includes the command format, a summary
of the purpose of the command, and a description of each operand.
The commands are arranged within each topic alphabetically by operation
and operand. (For example, VARY is considered an operation, and ACT
in VARY ACT is considered the operand.) The topics are:
- VTAM operator commands contains descriptions and the syntax of VTAM operator commands.
- Logon manager operator commands contains descriptions and the syntax of logon manager operator commands.
- Cross-reference for VTAM DISPLAY commands contains a cross-reference of the output from VTAM operator commands.
- "Architectural specifications" lists documents that provide architectural specifications for the SNA protocol.
- "Information APARS and technotes" lists information APARs for IP and SNA documents.
- "Accessibility" describes accessibility features to help users with physical disabilities.
- "Notices" contains notices and trademarks used in this document.
- "Bibliography" contains descriptions of the documents in the z/OS® Communications Server library.
