Startup Parameter Descriptions : Maximum Servers (-Mn)

Maximum Servers (-Mn)

Use Maximum Servers (-Mn) to limit the number of remote user servers that can be started by the broker process.
Note: The maximum value for the number of servers that may be started for a database is limited by available resources of the operating system.

1 Limited by available resources.

The maximum number of remote client servers that can be started on the system. The value specified is always incremented by 1 to provide a server for the primary login broker.
The performance trade-off to consider is swapping overhead for many servers versus overloading (slowing down) a server with too many clients. For more information on controlling memory use, see OpenEdge Data Management: Database Administration.
Also, use Minimum Clients per Server (-Mi) to adjust the actual number of servers in use. See the Maximum Clients Per Server (-Ma) and Minimum Clients per Server (-Mi) startup parameters for more information.
