Quiescing a node with immediate drain
On a high availability system, you can remove a node from a pool of active nodes by quiescing the node from a landing page. The default quiesce method is immediate drain, which does not require removing the nodes from the load balancer before starting the quiesce process.
To quiesce a node by using the landing page, do the following steps:
Identify the Pega Platform node or nodes that you want to quiesce.
Do either of the following:
- In Admin Studio, click .
- In Dev Studio, click .
Select the check box next to the node or nodes that you want to quiesce.
Click Quiesce. When the quiesce process is complete, the status of the node changes to Quiesce Complete in the Runstate or State column on the landing page.
- To cancel the quiesce process for the selected node or nodes, click Cancel Quiesce.
- The node state might not change to Quiesce Complete until after the node has been removed from the load balancer in the following step.
To prevent traffic from being directed to the quiesced node or nodes, configure the load balancer to remove the quiecsed node or nodes from the pool.
