 ## Installation and deployment tools
 
+### For Enterprise Users

 ### 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 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.

 # 3.6 Use JMeter to test OceanBase Database in simulated business scenarios
 
-JMeter is an open-source performance test tool developed by the Apache Software Foundation. It is built based on the Java platform and intended for load and stress tests on software applications. JMeter was designed for testing Web applications at the beginning and supports other test features later. You can use JMeter to simulate business SQL scenarios and analyze the performance of a database server under different loads. 
+This topic introduces the procedure for executing JMeter tests on the OceanBase Database.
+
+## JMeter Overview
+
+JMeter is an open-source load testing tool designed to measure and validate the performance of software applications, APIs, and databases. It supports simulating high user loads, generating realistic traffic, and providing detailed metrics on response times, throughput, and error rates—making it ideal for assessing the scalability and stability of target systems under test.
