Allocating Port Numbers to default.pingports and default.rmiports

These two settings are handled in a similar way. In both cases, the default port numbers have been carefully chosen to minimize the risk that the default port numbers are already allocated to another service.

• The default.pingports setting controls the server port numbers reserved for the machine identification service. These are UDP ports. The default value for this setting is:

  default.pingports=56098 57098
  

  If the default.pingports setting is removed from the startup.properties file, CA DataMinder uses port number 56098. On some machines, this port number may already be used by another service so a CA DataMinder installation will fail unless you specify a new number.

  CA DataMinder will use the first available UDP port listed in the setting.

• The default.rmiports setting controls the server port numbers assigned to the RMI registry. These are TCP ports. The default value for this setting is:

  default.rmiports=56099 57099
  

  If the default.rmiports setting is removed from the startup.properties file, CA DataMinder will use port number 56099. On some machines, this port number may already be used by another service so a CA DataMinder installation will fail unless you specify a fallback number.

  CA DataMinder will use the first available TCP port listed in the setting.

For example, to reallocate port numbers 5000 to the machine identification service and 5001 to the RMI registry, copy these lines to the startup.properties file on each CA DataMinder machine:

default.pingports=5000

default.rmiports=5001
