An LU-LU session exists to allow two users to communicate
in an SNA network. Once that communication is completed, the LU-LU
session should be terminated to allow the LUs to participate in
other LU-LU sessions. Terminating an LU-LU session stops an NRJE
workstation (after all NRJE LUs are down).
An NRJE workstation is stopped by either the NRJECONTROL HALT or NRJECONTROL STOP MPE command, or by either of the NRJE commands HALT and STOPWS (see Chapter 6 “Commands” of this manual). The issued
command causes the HP 3000 to send a TERM-SELF request to the host.
The SSCP sends a positive response to the HP 3000 LU then sends
a Control TERMinate (CTERM) request to the host LU. The host LU
sends a positive response to the SSCP then sends an UNBIND request
to the HP 3000 LU. SNA NRJE sends a positive response to the host
LU. The host LU sends a SESSion END (SESSEND) request to notify
the SSCP that the session has ended. Figure 4-2 “SNA NRJE LU-LU Session Termination” shows
a typical NRJE LU-LU session termination.
