Node classification

Node classification is the process of separating nodes, segregating them by purpose, and predefining their behavior.

By configuring a node with a node type during startup, you dedicate this node to perform particular actions by running only those agents, listeners, job schedulers, and queue processors that are mapped to this node type. For example, you can have a set of nodes dedicated to user requests, while other background processing can be disabled on these nodes to avoid performance issues for users.

To effectively use node classification, map agents, listeners, job schedulers, and queue processors to node types.

You map job schedulers and queue processors to node types when you create them. For more information, see Creating a Job Scheduler rule, Creating a Queue Processor rule.

Node type associations with agents, job schedulers, and queue processors have no effect on the system if node classification is not used at startup.

You can view the list of agents, listeners, job schedulers, and queue processors across the cluster with associated node types on the Node classification landing page.

You need the following privileges to view and manage agents, listeners, job schedulers, and queue processors:
  • pzAgentObserver to view the list of agents.
  • pzAgentAdministrator, pzClusterAdministrator to manage agents.
  • pzListenerObserver, pzClusterObserver to view the list of listeners.
  • pzListenerAdministrator, pzClusterAdministrator to manage listeners.
  • pzJobSchedulerObserver to view the list of job schedulers.
  • pzJobSchedulerAdministrator to manage job schedulers.
  • pzQueueProcessorObserver to view the list of queue processors.
  • pzQueueProcessorAdministrator, pzClusterAdministrator to manage queue processors.
