You can use ARIS PPM Cloud Controller to change the ports for the RMI registry.
Change RMI registry
Enter the following command in ARIS PPM Cloud Controller.
reconfigure ppm_core +ppmrmi.zookeeper.application.instance.port=<New port> (default=17500)
Change host name
To link the RMI to a host name other than your own, you must change the RMI registry using the following command.
Reconfigure ppm_core +ppmrmi.zookeeper.application.instance.host=<FQDN of RMI registry>
This may be necessary if PPM is being operated as a master/sub-server system in the cloud and the internal host name of a sub-server does not match the name accessible externally.
Example
Cloud VM has the internal host name SAGBASE. The computer is accessible externally under the host name IP_xxx.xxx.xxx.xxx.doma.in. The RMI registry for the sub-server VM must then be changed to the name accessible externally.
