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. 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.
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.
