An application sends a request to an OBServer node through an OceanBase Database Proxy (ODP). The ODP accurately routes the request to the OBServer node where the data replica is located. The number of connections that you can establish to an ODP is limited. Therefore, you must check both the ODP status and the number of corresponding connections and prepare for scale-out.
Check the ODP connection status in OCP
Log on to the OceanBase Cloud Platform (OCP) console. The Cluster Overview page appears.
In the Clusters list on the Cluster Overview page, find the target cluster and click its name.
In the left-side navigation pane of the page that appears, click Health Inspection.
In the Inspection Results list, view the ODP connection status.
