This topic describes how to replace a low-performance OBServer with one that provides higher performance.
Prerequisites
The logged-on user in the OceanBase Cloud Platform (OCP) console has the permission to update the cluster.
Your OceanBase cluster is managed in the current OCP cluster.
Otherwise, you need to use the current OCP cluster to take over your cluster. For more information, see Take over a cluster.
We recommend that you replace an OBServer only when your OceanBase cluster has at least three replicas.
Procedure
Log on to the OCP console.
The Clusters page automatically appears.
The Cluster Overview page automatically appears.
In the Clusters list on this page, find the target cluster and click its name to go to the Overview page of the cluster.
In the OBServers list, find the row that contains the target OBServer, and click Replace in the Actions column.
In the dialog box that appears, select a new host and click Replace .
Note
You can only select a host that matches the hardware architecture of the current cluster, and is in the same IDC as the OBServer to be replaced.
In the dialog box that appears, you can click View Task to view the progress of replacement.
You can also choose System Management > Tasks to view the progress of the task.
When the task status is Completed , and the status of the new OBServer is Running in the OBServers list on the Overview page, the original OBServer is replaced.
