Janus commands

Overview

The Janus command set (simply referred to as "Janus commands") consists of commands and subcommands that begin with the string JAN. The two Janus commands currently supported as of Sirius Mods version 6.3 are JANUS and JANUSDEBUG. For a full description of the Janus commands, see the Janus TCP/IP Base Reference Manual. The manual you are reading describes the commands and $functions that are specific to &TTHISP..

You use Janus commands to:

• Define Model 204 as a server on the TCP/IP network. Janus commands set port numbers for your Janus server applications and start, stop, and monitor Janus activity in the Model 204 address space.
• Define remote servers to the Model 204 client for access by Janus Open Client applications and Janus Sockets client applications, and define which remote hosts can establish connections with Janus Specialty Data Store, Janus Open Server, and Janus Sockets.
• Add security to Janus ports using Secure Sockets Layer (SSL) or Transport Layer Security (TLS) to provide encrypted communications.
• Define server rules (like redirection or security filtering for specific data types, users, or TCP/IP addresses) for Janus Web Server and Janus Sockets applications.
• Perform interactive, terminal-based debugging of Janus Web Server applications (using the JANUSDEBUG command).

Janus commands require the executing user to have System Manager privileges. The JANUSDEBUG command, which can be issued by any logged-in user, is an exception. Janus commands can also be issued as operator commands (on the Online virtual console under VM) or as replies to the HALT message under OS/390.

Janus commands make use of the following wildcard characters:

*	An asterisk represents any string of characters.
?	A question mark represents any character.
"	A double quote escapes wildcard translation of the special character that follows it.

For example, the following command starts all Janus ports whose names begin with the string BA (like BART, BARNEY, BALES, BAY):

JANUS START BA*

The following command drains all Janus ports whose names are three characters long, beginning with BA (BAY, BAD, BAX, etc.):

JANUS DRAIN BA?

The following command starts all Janus ports whose names end in ? (WHODONEIT?, WHERES_THE_BEEF?, WHAT?_ME_WORRY?, WHO_YA_GONNA_CALL?, etc.):

JANUS START *"?
