APPC Subsystem on MPE/XL Node Manager's Guide (30294-90007)

Chapter 2 51
Interactive Control Operator Commands
APPCCONTROL STOP
Description
Try to use APPCCONTROL STOP with the TYPE=Q parameter; this will
ensure orderly shutdown of the APPC subsystem. If it is not possible to
wait for current conversations to complete, escalate the shutdown type
to TYPE=P (protocol shutdown). A TYPE=P shutdown ensures that
resources used by the APPC subsystem for conversations are
successfully returned to the system before shutdown. If TYPE=P does not
work, use TYPE=K.
This command shuts down APPC sessions only; any LU-LU sessions
being used with other SNA Services remain active.
NOTE This command will not terminate any transaction programs. Users
must terminate any transaction programs that are still active after
their sessions have been terminated.
You can shut down the APPC subsystem programmatically by calling
the APPCStop intrinsic, described in Chapter 3 , “Control Operator
Intrinsics.”
