This parameter controls the maximum number of applications that can be connected to the instance. Typically, each application is assigned a coordinator agent. An agent facilitates the operations between the application and the database. When the default value for this parameter is used, the concentrator feature is not activated. As a result, each agent operates with its own private memory and shares database manager and database global resources such as the buffer pool with other agents. When the parameter is set to a value greater than the default, the concentrator feature is activated. The intent of the concentrator is to reduce the server resources per client application to a point where a DB2 Connect gateway can handle greater than 10 000 client connections.
A value or -1 indicates that the limit is max_coordagents.
