After the successful deployment, OceanBase Database creates a tenant named sys by default. This tenant is used to manage OceanBase Database. We recommend that you do not store business data in the sys tenant. Therefore, you must create a business tenant before you use OceanBase Database. This topic describes how to create a business tenant of OceanBase Database in OceanBase Cloud Platform (OCP).
Background
The GUI varies with the OCP version. This topic takes OCP V3.3.2 as an example. For OCP of other versions, see User Guide of the corresponding version.
Procedure
After you deploy an OceanBase cluster, the sys tenant will consume some CPU and memory resources. You can allocate the remaining CPU and memory resources to business tenants.
Log on to the OCP console as the admin user.
The Clusters page automatically appears.
On the Clusters tab, click the name of the target cluster.
The Overview page automatically appears.

On the OBServers tab, you can view the available resources of the servers.

OceanBase Database reserves two CPU cores and 4 GB memory for the OS. Therefore, the available resources for business tenants are calculated by using the following formulas:
Available CPU = Number of CPU cores of the server - Number of used cores - 2 (rounded down)
Available memory = Available memory size of the server - Used memory size - 4 GB
