Managing your high availability cluster

Updated on May 11, 2022

You can manage your high availability cluster using the HA Cluster Management page or in a Network Operations Center (NOC) integrated with the Pega API.

  • The HA Cluster Management page details the current status of any nodes running in high availability mode and is used to perform quiesce actions for a node.
  • The Pega API provides RESTAPIs for managing quiesce and other operations. For more information about using the Pega API to manage high availability clusters, see Integrating with Pega APIs and services.

Operators with the following roles can access the HA Cluster Management page:

  • PegaRULES:HighAvailabilityAdministrator
  • PegaRULES:HighAvailabilityQuiesceInvestigator
