OMVS, a 3270 terminal interface to the z/OS shell

The explanations and examples in this topic assume that the z/OS® shell has been set up in your profile. The information presented here is primarily directed towards users of the z/OS shell.

The TSO/E OMVS command is one method of accessing the z/OS shell. It provides a 3270 terminal interface to the shell. To use the OMVS interface to the shell, you must be working at a 3270 terminal or a computer with 3270 emulation.

You issue the OMVS command from TSO/E:

In an SNA network, remote users access TSO/E through VTAM®.
In a TCP/IP network, remote users that have the Telnet 3270 client function access TSO/E by entering the TN3270 command. See the TCP/IP documentation for your system or the documentation for your computer's 3270 emulation.

For information about using an asynchronous terminal interface to the shell, see The asynchronous terminal interface to the shells.
