Managing your high availability cluster
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.
Operators with the following roles can access this page:
- PegaRULES:HighAvailabilityAdministrator
- PegaRULES:HighAvailabilityQuiesceInvestigator
You can access this page from Dev Studio by clicking .
The following data is displayed on this page for each node.
| Column | Description |
| Node | The name of the node |
| NodeID | The node ID |
| Runstate | The status of the node:
|
| Active Users | The number of active users |
| Last Pulse | The date and time of the last system pulse |
| Last Started | The date and time that the node was last started |
To perform an action on any of the nodes listed on this page, select the check box next to the node(s) and then click one of the following buttons:
- Quiesce – Begin the quiesce process for the selected node(s).
Note: When using the slow drain method for quiesce, you must take the node(s) out of the load balancer rotation before performing this action. - Cancel Quiesce – Cancel the quiesce process for the selected node(s).
- Refresh Data – Refresh the node data listed on the page.
- Managing the cluster using the Pega API
You can use the Pega API to integrate Pega Platform high availability into a Network Operations Center (NOC). The Pega API provides RESTAPIs for managing quiesce and other operations.
- Quiescing high availability nodes
Quiesce is a process for cleanly taking a Pega Platform node out of service for maintenance or other activities.
