MPE Commands
SNACONTROL STOP
SNACONTROL STOP
Stops an SNA node and all activity on the node.
Syntax
SNACONTROL STOP;NODE= NodeName [;TYPE= StopType ]
Use
SNACONTROL STOP can be issued from a session, a job, a program, or in
break. Pressing
[BREAK] has no effect on this command.
Parameters
NodeName Conditionally required. The name of the active SNA
node you want to stop. The name can be up to eight
alphanumeric characters long; the first character must
be alphabetic.
If only one SNA node is active, this parameter is
optional: If you do not include it, the active node is
stopped. If
more than one node is active, this parameter
is required: If you do not include it, a list of all
configured SNA nodes is displayed, but no node is
stopped; you can then reissue this command with the
appropriate node name.
StopType How SNA Transport is to stop the node:
• K = (Kill) The node is stopped immediately. To the
users of the node, this is like a link failure. The
remote system is not notified that SNA Transport is
stopping.
CAUTION Data can be lost in a kill shutdown.
• P = (Protocol) SNA Transport notifies the SNA
services that it is stopping. Each service interrupts
sending and receiving all active data sets, and tries
to stop the LU-LU sessions. SNA Transport then
stops the LU-SSCP sessions and the PU-SSCP
session, but it does
not stop the node until all SNA
Transport users have terminated their sessions.
