Applies to:Oracle GlassFish Server - Version 3.1.2 and later
Information in this document applies to any platform.
It is noticed than when a GlassFish Server instance is started, which is using an embedded Message Queue (MQ) broker, that there is a port opened whose value is 100 greater than the broker's principle portmapper port. For example, if the MQ broker is using the default port of 7676, then the GlassFish instance's process also has port 7776 open. In the following example the broker portmapper port is 31206:
The broker's portmapper port can be seen as the last port in the URL, with the RMI port listed before it, as highlighted in the output above.
Please note that there is also an ephemeral port being used, as there is no port listed following the first appearence of the hostname in the url, "myserver".
Therefore there are three ports that this article discusses:
- JMX RMI Port
- RMI Port
- Broker Port Mapper Port
