Geronimo supports the clustering of web applications by using WADI, Application Distribution Infrastructure. When a clustered web application is deployed in Geronimo, the deployer adds dependencies on two configurations:
org.apache.geronimo.configs/clustering//car
: This configuration contains runtime dependencies that the clustered application must have. This configuration also has aNode GBean
that defines a unique node name with which the Geronimo server instance will be identified in the cluster. Use theclusterNodeName
property invar/config/config-substitutions.properties
to reconfigure the node name of your Geronimo server instance.org.apache.geronimo.configs/wadi-clustering//car
: This configuration contains WADI-related GBeans used to configure the behaviour of clustered applications and the WADI group communication service shared by all of the clustered applications to communicate with each other.The number of replicas to be maintained across the cluster for a session is...
