The Listener
The listener on the server provides three functions:
* It listens for connection requests.
* It validates the server login name.
* It sets up a direct communication line between the client and
server.
The listener monitors a specified datacomm port for any incoming
connection requests. When it receives a request, it validates the server
login name for the user on the client and then creates a database process
for that user. The listener redirects communications so that the user
and the database process communicate directly with one another over the
network. It then resumes listening for more connection requests.
You manually start the listener on the server after ALLBASE/SQL has been
installed.[REV BEG] When you stop running the listener, no further
connection requests are accepted. However, any remote database activity
that is already in progress will not be affected and will terminate
normally.
Listener and network status and errors are recorded in a listener log
file (HPDANSLG.PUB.SYS) that you can check in the event of problems with
remote access. The listener must not be running for this to work.[REV

For instructions on starting and using the listener and an example of a
listener log file, refer to "Setting Up ALLBASE/NET on an MPE/iX Server"
in the "Setting Up ALLBASE/NET" chapter.
