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 using OceanBase Database. This topic describes how to create a business tenant of OceanBase Database from OceanBase Cloud Platform (OCP).
Background
The graphic user interface (GUI) varies with the OCP version. This topic takes OCP V2.5.0 as an example. For other OCP versions, see User Guide of the corresponding version.
Procedure
After the OceanBase cluster is deployed, the CPU and memory resources of the entire service are allocated to the operating system and the sys tenant of the OceanBase database. The available CPU and memory resources can be allocated to the business tenant.
Log on to the OCP console as the admin user.
The Cluster Overview page appears by default.
On the Clusters tab, click the cluster name.
The Overview page appears.
On the OBServers tab, you can view the available resources of the servers.
OceanBase reserves 2 CPU cores and 4 GB memory for the operating system. Therefore, the available resources for business tenants are calculated with 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
