DBS 10,000 – – 20
n
The maximum number of concurrent connections made to the database. A concurrent connection can be a single user, or it can be an application server, which could service multiple users. The state of the application server is also important when determining the concurrent connections. After n concurrent connections have been made to the OpenEdge database, additional connection startup attempts are rejected.

-n must be high enough to include local and remote connections as well as background writers (APWs, BIWs, and AIWs), PROWDOG processes, and PROMON sessions.

To modify this parameter while the database is online, use PROUTIL INCREASETO.

See Maximum Clients per Server (-Ma) and Maximum Servers (-Mn) for more information.

You can use this parameter to support continuous operation of the database. For more information, see Change database parameters while the database is running.
