NA NRJE Workstation Startup and Shutdown
Stopping a Workstation
Stopping a Workstation
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 shows a typical
NRJE LU-LU session termination.
