Add a zone

You can add zones to a cluster that you manage.

Prerequisites

• The logged-on user in the OceanBase Cloud Platform (OCP) console has the permission to update the target OceanBase cluster.

• The target OceanBase cluster is managed in the current OCP cluster.

  Otherwise, you need to use the current OCP cluster to take over the OceanBase cluster. For more information, see Take over a cluster.

• The target is not a standalone centralized database.

Procedure

1. Log on to the OCP console.

2. In the left-side navigation pane, click Clusters to go to the Clusters page.

3. In the Clusters list on the page, find the target cluster and click its name.

4. In the upper-right corner of the Overview page, click Creat Zone.

5. In the dialog box that appears, set the zone information.

   By default, only one zone is added. You can click Creat Zone to add more zones.

   The following table describes the parameters required for setting the zone information.

   Parameter	Description
   Zone Name	The name of the zone.
   IDC	The IDC where the zone is located.
   Host Type	Optional. If you select a host type, the host list is filtered based on the host type.
   CPU Architecture	The CPU architecture of the host in the zone must be the same as that of the cluster. After you select an architecture, the system checks whether an installation package for the CPU architecture of the current cluster exists. If the installation package for the specified architecture does not exist, the zone cannot be added.
   Host	The IP address of the host. You can select multiple IP addresses. In a production environment, we recommend that the size of the log disk be at least three times that of the memory size of the host. To avoid performance issues, we recommend that you do not create the data directory and the log directory on the same disk.
   Custom Settings	Configure the OS User, Path Settings and Port Settings of the OBServer node. For more information, see Create a distributed cluster.
   Parameter Configurations	The startup parameters of all OBServer nodes in the zone. For more information, see OceanBase Database parameters. If you do not specify the OBServer node startup parameters, the startup parameters specified when you created the cluster are used.

   

6. Click OK.

   In the dialog box that appears, you can click View Task to view the creation progress.

   You can also choose System Management > Tasks to view the progress.

   When the task enters the Completed state, and the status of the zone is displayed as Running in the Zones list on the Overview page, the zone is created.
