Cluster members are configured on a Geronimo server, which may but is not required to be a member of the cluster. This is achieved by adding a org.apache.geronimo.farm.config.BasicNodeInfo GBean for each cluster member to the farming configuration of config.xml. This GBean looks like this:
| Code Block |

<gbean name="org.apache.geronimo.configs/farming/2.1/car?ServiceModule=org.apache.geronimo.configs/farming/2.1/car,j2eeType=NodeInfo,name=NodeInfo2" class gbeanInfo="org.apache.geronimo.farm.config.BasicNodeInfo"> <attribute name="name">${PlanClusterNodeName}<>NODE2</attribute> <xml-attribute <attribute propertyEditor="org.apache.geronimo.farm.config.BasicExtendedJMXConnectorInfoEditor" name="extendedJMXConnectorInfo"> <ns:javabean class="org.apache.geronimo.farm.config.BasicExtendedJMXConnectorInfo" xmlns:ns4="http://geronimo.apache.org/xml/ns/attributes-1.2" xmlns:ns="http://geronimo.apache.org/xml/ns/deployment/javabean-1.0" class="org.apache.geronimo.farm.config.BasicExtendedJMXConnectorInfo xmlns=""> <ns:property name="username">system</ns:property> <ns:property name="password">manager</ns:property> <ns:property name="protocol">rmi</ns:property> <ns:property name="host">localhost</ns:property> <ns:property name="port">1099<>1100</ns:property> <ns:property name="urlPath">JMXConnector</ns:property> <ns:property name="local">true<>false</ns:property> </ns:javabean> </xml-attribute> </gbean> |
It defines network address (host, port, urlPath) and credentials (username and password) to be used to connect to the cluster member via JMX. Such declarations are to be included within the config.xml file, farming module of your Geronimo server.
By default, the farming configuration defines the local server as a cluster member. To exclude it, you can prevent the GBean NodeInfo to start.
