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.
Note:
- 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.
