Release 10.1A: OpenEdge Deployment:
Managing 4GL Applications

> ## Connection denials when the user count is exceeded

> When a user attempts to connect to a database using either a `CONNECT` statement or a command and exceeds the maximum number of users allowed to connect to the database, as specified with the Number of Users (`-n`) startup parameter, OpenEdge denies the connection request and displays an error message. OpenEdge also records the connection denial in the database log file.

> Figure 2–1 shows a connection denial when a connection request exceeds the maximum number of users. In this example, the Number of Users (`-n`) startup parameter allows a maximum of three user connections. When the fourth user attempts to connect, OpenEdge denies the connection.

> Figure 2–1: Connection denial when the user count is exceeded

> When OpenEdge denies a user connection because the maximum number of users is exceeded, you must terminate an existing connection before the user can establish a new connection.

> You can use database usage reporting features to track user connections to databases. For information about database usage reporting features, see OpenEdge Data Management: Database Administration and OpenEdge Getting Started: Installation and Configuration .

> For more information about the Number of Users (-n) startup parameter, see OpenEdge Deployment: Startup Command and Parameter Reference .

> For information about coding applications to handle connection denials, see OpenEdge Development: Programming Interfaces .
