A node is a machine running a BIRT iHub instance. The system administrator adds a node to a BIRT iHub cluster to improve availability and throughput and scale the installation to meet processing requirements.
Every cluster node must have network access to the following directory and resources to join the cluster:
The shared configuration directory
Cluster resources, such as printers, database systems, and disk storage systems
Each node gets its configuration from a template in acserverconfig.xml, which is located in the shared configuration directory along with the license file, acserverlicense.xml. The acserverconfig.xml file also contains other configuration parameters specifying the host names, volume names, port numbers, printers, and services used by nodes in the cluster.
When the Process Management Daemon (PMD) starts up, it reads these configurations and exposes the settings to the process environment variable list. When a node joins a cluster, the node configures itself using the designated template.
