3.4. Configure Server Hinting in Library Mode

In JBoss Data Grid's Library mode, Server Hinting is configured at the transport level. The following is a Server Hinting sample configuration: 
<transport clusterName = "MyCluster"
           machineId = "LinuxServer01"
           rackId = "Rack01"
           siteId = "US-WestCoast" />
As illustrated in the sample configuration, the following configuration attributes are used to configure Server Hinting in JBoss Data Grid:
  • The clusterName attribute specifies the name assigned to the cluster.
  • The machineId attribute specifies the JVM instance that houses the original data. This is particularly useful for nodes with multiple JVMs and physical hosts with multiple virtual hosts.
  • The rackId parameter specifies the rack that contains the original data, so that other racks are used for backups.
  • The siteId parameter differentiates between nodes in different data centers replicating to each other.
The listed parameters are optional in a JBoss Data Grid configuration. However, if Server Hinting is not configured, JBoss Data Grid's distribution algorithms are allowed to store replications in the same node/data center/rack as the original data.
