 ### OCP
 
 OceanBase Cloud Platform (OCP) is an enterprise-level management platform tailored for OceanBase clusters. It is compatible with all major OceanBase Database versions. It provides GUI-based management capabilities, including lifecycle management of database components and resources (such as hosts, networks, and software packages), fault recovery, performance diagnostics, as well as monitoring and alerting. OCP aims to help enterprises manage OceanBase clusters more efficiently at lower IT O&M costs and shorten the user learning curve. 
 
 For more information about the system architecture and features of OCP, see [OceanBase Cloud Platform](https://en.oceanbase.com/docs/common-ocp-10000000001553919). 
 
-### OCP Express
-
-OCP Express is a web-based management tool for OceanBase Database V4.x. Integrated with OceanBase clusters, OCP Express allows you to view key performance metrics and perform basic database management operations on OceanBase clusters. 
-
-OCP Express is derived from OCP. It retains the core capabilities of OCP and adjusts the overall layout of features to provide a brand-new user experience. Feature configurations are also rearranged in OCP Express so that OCP Express can be deployed on any database node with the minimum resource consumption. OCP Express allows you to gain extensive control over OceanBase Database V4.x at minimum costs. 
-
-OCP Express is intended for lightweight O&M management and is integrated with the managed OceanBase cluster for dedicated management. It minimizes resource consumption while meeting basic O&M requirements. OCP is intended for the O&M of large-scale complex clusters, and you can manage multiple OceanBase clusters in OCP. It provides more management capabilities than OCP Express. An additional OceanBase cluster is needed to store the data of OCP, and higher resource configurations are needed to implement the capabilities of OCP. 
-
-> **Note**
->
-> OCP Express applies to the O&M of an OceanBase cluster in a development and testing environment with no more than 20 servers and 3 to 5 tenants. We recommend that you use OCP in a production environment.

-### DOOBA
-
-DOOBA is an internal O&M script of OceanBase Database that is developed in Python for performance monitoring. After you connect to the sys tenant of OceanBase Database by running a MySQL command, you can run DOOBA to display the queries per second (QPS) and the average response time (RT) of the SQL statements executed in the tenant in real time. The supported SQL types include `SELECT`, `UPDATE`, `INSERT`, `DELETE`, and `COMMIT`. You can also view the QPS and RT of SQL statements executed on each OBServer node.

OBShell supports cluster O&M and provides O&M and management APIs based on OceanBase Database. This allows products from different ecosystems to manage the same OceanBase cluster in a unified manner, reducing the difficulty in and costs of OceanBase cluster management.

-Unlike OCP, OCP Express does not support advanced O&M capabilities, such as backup and restore, version upgrade, and cluster scaling, aiming to reduce resource usage. OCP Express is more lightweight than OCP and is designed to meet the basic O&M and monitoring requirements of a single cluster. We recommend that you use OCP in a production environment.
