The JANUS command is used to specify the configuration of Janus ports and, in a few cases, system-wide Janus configuration settings. While the JANUS command can be issued by customers that are not authorized for any Janus products, only web ports can be defined at these sites, and only at sites with a minimal number of ports (3).
The JANUS command can be issued as either of these:
- An operator command, that is, as a reply to the HALT message under OS/390
- A command typed on the Online virtual console under CMS
See Janus commands for the complete JANUS command syntax.
