Description
The RPM package of OCP-Agent that matches the current OceanBase Cloud Platform (OCP) version is built in the Docker container of OCP. When you deploy OCP, the version of OCP-Agent installed on the managed host must be consistent with the built-in version. If they are inconsistent, this alert is generated. The version number of OCP consists of three digits, such as 4.2.1. The version number will be followed by an 8-digit build number. By default, only the 3-digit version number is checked. To check the 8-digit build number, set ocp.build.version.check to true.

- Sample: Test. Host: xxx.xxx.xxx.xxx. Alert: host_agent_version_not_same Expected OCP-Agent version: 4.2.1-20230928. Host OCP-Agent version: 4.2.0-20230921
Impact on the system
OCP-Agent is a process deployed on a host that is taken over by OCP. It comprises a management (O&M) process and a monitoring process. If the version of OCP-Agent is inconsistent with that of OCP-Server, the following issues will be caused:
- O&M operations, such as routine O&M operations on OceanBase Database, OceanBase Proxy (OBProxy), and hosts, cannot be performed.
- Monitoring data of the later version cannot be collected.
Possible causes
- OCP-Agent fails to be upgraded due to some causes, but OCP-Server is successfully upgraded.
- OCP-Agent of an earlier version is installed on the host.
Solutions
Install OCP-Agent of the same version as OCP-Server. We recommend that you install OCP-Agent and OCP-Server to the same BP version. Select the built-in version on OCP-Server to install OCP-Agent again.
