The port number that is the highest in a specified range.

Use Maximum Dynamic Server (-maxport) to specify the highest port number in a specified range of port numbers accessible to a client. You specify the lowest port number with the -minport parameter. The range of port numbers defined by the -maxport and -minport parameters provides client access to an OpenEdge server that is behind a firewall. Some operating systems choose transient client ports in the 32,768-to-65,535 range. Choosing a port in this range might produce unwanted results.

The Maximum Dynamic Server (-maxport) parameter may be modified while your database is online using PROMON or through the _DbParams VST. This change will only take effect on the primary broker and any newly spawned servers. Online changes to existing secondary brokers will require a restart.

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