IBM Tivoli Composite Application Manager for Application Diagnostics, Version 18.104.22.168
More than one data collector installed on a server with a firewall enabled: setting a range of port numbers - J2EE Agent
The configuration program requires you to set unique port numbers for probe.rmi.port and probe.controller.rmi.port. There will be problems with communication with the Managing Server if ports for separate data collectors installed on a server with a firewall are not unique. If you have many data collectors, it might be difficult to set unique ports for all the data collectors.
Instead of having to make sure that individual port numbers assigned for each of the data collectors is unique, you can set a range of port numbers in the data collectors' properties files. The following procedure will reset the individual port numbers entered during the configuration to a range of port numbers:
For each data collector, in the custom_directory/datacollector_custom.properties file, set the following properties:probe.rmi.port=range_of_port_numbers probe.controller.rmi.port=range_of_port_numbersFor example,probe.rmi.port=8200-8299 probe.controller.rmi.port=8300-8399
If you use the same range for both properties, make sure that range is larger than or equal to 2 times the number of data collectors installed on the server.
