Server Installation Guide Initialization and Termination
Chapter 4 Initialization and Termination
Initialization
The Command Controller and Facility Messenger components must be initialized 
by the user through the APM.  Command Controller needs to be started prior to or 
in conjunction with a Facility Messenger.  To begin initialization,  select the Non-
CRT Application Control option of the APM’s System Operations Menu.  (Make 
sure that OAI system has been initialized before you begin this process.)  Then, 
choose the Initialize command, and select the Command Controller and Facility 
Messenger application names.  For more information, refer to the APM Operations 
Manual.
The Logical Monitor component is initialized by Facility Messenger when needed.  
The user should never start the Logical Monitor manually.  Only two commands 
require an active Logical Monitor:  Initialize Logical Station Monitoring command 
(60) and Terminate Logical Station Monitoring command (61).
Command Controller does not open the command and response FIFOs (or 
command file) until a Facility Messenger is ready to receive commands.  If the 
FIFOs do not exist, Command Controller creates them.
Termination
The Command Controller can be terminated in two ways:
The user chooses the Terminate command form the APM’s Non-CRT 
Application Control Menu.
The user’s application issues a Terminate Controller command (09) to Server. 
In both cases, Command Controller tells all Facility Messengers to terminate and 
closes the FIFOs (or command file) before terminating itself.  Any responses to 
completed commands remain in the response FIFO until the non-APM application 
reads them or closes the FIFO.  Any unprocessed or incomplete commands are lost.
The user may terminate a Facility Messenger from the APM at any time.  The 
Facility Messenger will notify the Command Controller that is terminating,  halt 
any Logical Monitor, and release its OAI association with the NEAX.  Any 
incomplete commands for that Facility Messenger are lost.
A Logical Monitor is usually terminated by its corresponding Facility Messenger 
(via the APM).  However, the user may also terminate a Logical Monitor by using 
the APM.  Prior to termination, the Logical Monitor disconnects any listening 
parties, stops monitoring all lines, and releases its OAI association with the NEAX.
