You shut down the APPC subsystem by issuing the APPCCONTROL STOP command. Whenever the APPC subsystem shuts down, performance statistics
are logged for all sessions that were active at the time of the shutdown
(if logging is configured and statistics gathering is enabled).
The APPCCONTROL STOP command shuts down the APPC subsystem by deactivating
all APPC sessions. There are three shutdown types you can use: KILL,
PROTOCOL, and QUIESCE. See the description of APPCCONTROL STOP in Chapter 2 “Interactive Control Operator Commands” for a description
of shutdown types.
The following is an example of logging messages you should
see for normal APPC subsystem shutdown:
APPC: Session Stopped, Session ID=4101, Reason=APPC_Quiesce (APPCLOG 7)
APPC: Session Stopped, Session ID=4102, Reason=APPC_Quiesce (APPCLOG 7)
APPC: Subsystem Stopped. (APPCLOG 1) |
A session termination message will be logged for each session
that is deactivated. The Reason field in the termination message indicates the type
of shutdown that occurred. (The description of the APPCCONTROL STOP command in Chapter 2 “Interactive Control Operator Commands”explains all the
shutdown types.) QUIESCE, the type that is seen in the example above,
is the default shutdown type.
Shutting down the APPC subsystem does not affect the operation
of SNA/SDLC Link/XL, so any other SNA Services that may be using
the SNA link are not affected.
The SNACONTROL STOP command shuts down SNA/SDLC Link/XL, which causes all LU-LU
sessions on the SNA node to shut down, including those used for
the APPC subsystem. The shutdown type (QUIESCE, PROTOCOL, or KILL)
that you specify in the SNACONTROL STOP command is the shutdown type for every LU-LU session
on the node you are shutting down. For example, an SNACONTROL STOP command issued with a shutdown type of KILL (immediate
shutdown of the node) causes a similar termination of all LU-LU
sessions on the node specified. For information on the SNACONTROL STOP command, see the SNA Link/XL Node
Manager's Guide.
