OceanBase Cloud Platform

OceanBase Cloud Platform (OCP) is an enterprise-level management platform designed specifically for managing OceanBase clusters. It is compatible with all major versions of the OceanBase Database. OCP provides a range of GUI-based management features for OceanBase Database and related resources, including full-lifecycle management, monitoring and alerting, performance diagnostics, fault recovery, and backup and restore. With OCP, you can manage OceanBase Database more efficiently, which can help reduce IT operation and maintenance costs and minimize the time and effort needed to learn and master the system.

1
Upload software packages
OCP allows you to upload the installation packages of OceanBase products and services such as OceanBase Database, OCP-Agent, OceanBase Database Proxy (ODP), and the backup and restore services.
For more information, see "Upload a software package".
2
Add hosts
Before you create a cluster, you must add hosts to OCP.
For more information, see "Add a host".
3
Create a cluster
You can create a cluster based on your business needs.
For more information, see "Create a cluster".
4
Create a tenant
A tenant can be seen as a container for database objects and resources such as CPU, memory, and I/O resources. You can create tenants in a cluster as needed.
For more information, see "Create a tenant".
