FACT(s) (Environment):
All Supported Operating Systems
DataServers
FIX:
As of Progress 9.1E, 10.1x and 10.2A , there is no capability to limit the port range for the server processes of the DataServer Broker either using probroker or unified broker. Currently, the DataServer Broker(s) dynamically assign the server port(s), thus minimum and maximum port range can not be manually controlled. The default minport for UNIX is 1025 and maxport is 2000.
Starting 10.2B, data server broker has been enhanced to have the capability of limiting port range for servers. _probrkr can be started with -dsminport and -dsmaxport to limit server port range. For unified broker, use standard configuration entries in ubroker.properties file to configure min and max ports.
For users that need to control ports through Firewall, following information is helpful: on windows, the DataServer broker, either probroker or unified broker, uses ports starting 3001, 3002, 3003, etc when allocating ports for servers;on UNIX, the broker uses ports starting 1025 and the ceiling is 2000. The ports are reusable, ie. ports are released when clients disconnect and reused when new clients connect. In a firewall environment, two way TCP should be enabled for these ports, the number of ports should corresponds to the number of maximum clients.
