| Stop a cluster | You can perform this operation to stop a cluster managed by OCP. |
| Restart a cluster | You can perform this operation to restart a cluster managed by OCP. |
| Create a zone | You can perform this operation to create a replica for a cluster managed by OCP. |
| Restart a zone | You can perform this operation to restart all servers in a zone. |
| Stop a zone | You can perform this operation to stop all servers in a zone. |
| Delete a zone | You can perform this operation to delete a replica of a cluster managed by OCP. |
| Add an OBServer | You can perform this operation to add a server to a cluster managed by OCP. |
| Restart an OBServer | You can perform this operation to restart an OBServer of a cluster. |
| Stop an OBServer service | You can perform this operation to stop an OBServer service of a cluster. |
| Stop an OBServer process | You can perform this operation to stop an OBServer process of a cluster. |
| Replace an OBServer | You can perform this operation to replace an OBServer of a cluster. |
| Delete an OBServer | You can perform this operation to delete an OBServer of a cluster. |
| Create a tenant | You can perform this operation to create a tenant in the OceanBase cluster. |
| Upgrade the version of an OceanBase cluster | You can perform this operation to upgrade the version of an OceanBase cluster. |
| Change the password | You can perform this operation to change the password of the root user of the SYS tenant in a cluster managed by OCP. |
| Download logs | You can perform this operation to download logs related to the OceanBase cluster, OBProxy, and host. |
| Disable SQL collection | You can perform this operation to disable SQL collection. |
| View the SQL collection history | You can perform this operation to view the history of all SQL collection activities. |
| View the topology of a cluster | You can perform this operation to view the logical relationships between zones and OBServer nodes in a cluster or tenant. |
| Cluster tenant management overview | You can perform this operation to view the resource distribution information of all tenants, and monitoring data of the top 5 tenants in the cluster that you manage on the overview page. |
| Performance monitoring | You can perform this operation to view the cluster performance data in different dimensions. |
| View unit distribution | You can view the unit distribution to check the physical distribution and resource usage of each tenant in OceanBase clusters. |
| View resource usage | You can view the resource usage tendency of the current cluster. |
| Modify the compaction configuration | You can perform this operation to modify the strategies that apply to daily major and minor compactions. |
| Details of major compaction | You can perform this operation to view the details of the last major compaction. |
| Major compaction statistics | You can perform this operation to view the statistics of the last three major compactions. |
| Perform major compaction | You can perform this operation to compact incremental data with the baseline data. |
| Cluster backup and recovery | You can perform this operation to back up or recover a cluster and view information of backup and recovery tasks. |
| View parameters | You can perform this operation to view all the parameters of a cluster. |
| Modify parameters | You can perform this operation to modify the values of cluster parameters. |
| Cluster parameter type description | You can perform this operation to learn about the types of cluster parameters based on the description. |
| View the parameter modification history | You can perform this operation to view the history of parameter modifications. |
| Manage cluster parameter templates | You can use a parameter template to create a series of clusters that have similar configurations without repeatedly configuring cluster parameters. |
