Activating the APPC Subsystem
Activating the APPC Subsystem
The subsystem is activated by issuing the APPCCONTROL START
command. The APPCCONTROL START command can be issued from any
user terminal by anyone with NM capability. Once the command is
issued, the APPC subsystem and all APPC sessions configured for
automatic activation will come up. (Automatic activation is discussed in
Chapter 4 , “APPC Subsystem Configuration,” “APPC Subsystem
Configuration.”)
NOTE The APPCCONTROL START command will not cause the activation of the
SNA link product if it is not already activated. The SNA link product
must be explicitly activated using the SNACONTROL START command.
When the APPC subsystem starts up, it generates startup and logging
messages. These messages tell you how activation is progressing.
Logging messages can be directed to the system console, a disk file, or a
user terminal (depending upon configuration). The startup messages
returned by the APPC subsystem are directed back to the terminal
from which the APPCCONTROL START command was issued. The startup
messages you should see after issuing the APPCCONTROL START
command are shown below:
:APPCCONTROL START
APPC: Subsystem start up begun.
APPC: Opening internal trace file - NMTC nnnn .PUB.SYS or user trace file .
APPC: Control Operator start-up completed.
At this point, the APPC subsystem is active, but no sessions have been
started yet.
APPC subsystem logging messages record the establishment of APPC
sessions. Typical messages are shown below. They could be directed to a
user terminal, the console, a disk file, or all three.
APPC: Subsystem Started (APPCLOG 0).
APPC: Session Started, Session ID=41 (APPCLOG 6).
APPC: Session Started, Session ID=42 (APPCLOG 6).
