IBM OS/390 User Manual

As with VSE, remote systems and workstations can communicate through NJE or
RJE via commands and messages. Some remote workstations and systems have
console operators, while others may not. The remainder of this chapter
describes how to communicate via JES2 commands.

There are many kinds of remote workstations: BSC and SNA, ones with just a
reader and printer, and others with consoles, disks and spooling capability.
Some have human operators, others do not. Some must be managed by the
central host operators, others by a remote operator.

Usually, the remote operator controls the RJE session once the lines and
interfaces are enabled. However, the host OS/390 operator can also initiate
some sessions and may become involved with recovery operations if problems
arise. Here are some JES2 commands to support RJE:

Start the JES2/VTAM ACB (for SNA remotes)

Start the line

Start the RJE session (SNA only)

Re-start the line

Drain the line

′

′

Send a message to the remote operator.

You should set up an RJE workstation (of each type) to orient your remote
operators to the JES2 environment, show them how to submit jobs, retrieve
output, and enter commands.

Here are some JES2 RJE statements to sign on and off:

•

For BSC Remotes, use /*SIGNON  to sign on, and /*SIGNOFF  to sign off.

•

For SNA Remotes, use LOGON - sign on to JES2, and LOGOFF - sign off
(these are actually VTAM commands).

See Chapter 6 in the 

JES2 Initialization and Tuning Guide for more details.

The most common commands for RJE are for printers:

Start the printer initially or after a setup message

Display forms queued to this remote

Display jobs that can be affected by Remote 3

Display output that is destined for Remote 3

Set up printer n for other forms, classes and so on
