Creating the AliasDB and NETUsers Files
After ALLBASE/SQL has been installed on both the clien t and the server, the AliasDB and NETUsers les m ust be created using NETUtil. Adding the rst prole to the AliasDB or NETUsers le automatically creates the respectiv e le. These proles allow specied users on the client to access particular DBEn vironments on the server.
As system administrator on the clien t, you invoke NETUtil and use the ADD ALIAS command to add an alias prole to the AliasDB le. ADD ALIAS prompts y ou for details about the specic DBEn vironment to be accessed. Use ADD ALIAS to add more alias proles to the AliasDB le as needed.
As system administrator on the serv er, you invoke NETUtil and use the ADD USER command to add a user prole to the NETUsers le. ADD USER prompts y ou for details about the specic user who will be accessing the remote DBEn vironment. Use ADD USER to add more user proles to the NETUsers le as needed.
For
The Listener
The listener on the serv er provides three functions: It listens for connection requests.
It validates the serv er login name.
It sets up a direct comm unication line between the client and server.
The listener monitors a specied datacomm port for an y incoming connection requests. When it receives a request, it validates the serv er login name for the user on the clien t and then creates a database process for that user. The listener redirects comm unications so that the user and the database process comm unicate directly with one another o ver the network. It then resumes listening for more connection requests.
You manually start the listener on the serv er after ALLBASE/SQL has been installed. When you stop running the listener, no further connection requests are accepted. Ho wever, any remote database activit y that is already in progress will not be aected and will terminate normally.
Listener and network status and errors are recorded in a listener log le (HPDANSLG.PUB.SYS) that y ou can check in the event of problems with remote access. The listener m ust not be running for this to w ork.
For instructions on starting and using the listener and an example of a listener log le, refer
to \Setting Up ALLBASE/NET on an MPE/iX Serv er" in the \Setting Up ALLBASE/NET" chapter.
