Connection ports and base port

IBM® Spectrum Symphony requires exclusive use of certain ports for communication. IBM Spectrum Symphony uses the same seven consecutive ports on every host in the cluster. The first of these hosts is called the base port.

The default base connection port is 7869. IBM Spectrum Symphony always uses seven consecutive ports that start from the base port. By default, IBM Spectrum Symphony uses ports 7869 to 7875.

The ports can be customized by customizing the base port. For example, if the base port is 6880, IBM Spectrum Symphony uses ports 6880-6886. Symphony needs the same ports on every host, so you must specify the same base port on every host.

To change the base port after installation, shut down the cluster and use the egoconfig setbaseport command on each host in the cluster. Start the cluster to use the new connection ports.
