This topic describes how to take over MetaDB in the OceanBase Admin Toolkit (OAT) console. Earlier versions of OAT cannot be smoothly upgraded to the current version because the new version has been restructured. Therefore, the current version of OAT must take over the products and components deployed by using earlier versions of OAT to monitor their status and manage their upgrades.
Prerequisites
Before you take over MetaDB, make sure that:
- You have added the image used by MetaDB.
- You have installed and logged on to OAT as a super administrator or an O&M engineer. For more information, see Install OAT.
- You have added the server where MetaDB is to be taked over. For more information, see Add a server.
- The server meets the requirements for taking over MetaDB.
Procedure
To take over MetaDB, perform the following steps:
In the left-side navigation pane, choose Product Service > Component Management.
On the Component Management page, click Take Over Component in the upper-right corner, and choose Take Over MetaDB.
On the Take Over MetaDB page, specify the related parameters.
The following table describes the basic parameters of MetaDB.
Parameter Description MetaDB Image The Docker image of MetaDB. Component Name The name of the component, which must be unique. Default value: metadb.Server The IP address of the server where the MetaDB is to be taked over. CPU The number of CPU cores allocated to the MetaDB. Default value: 32C.Memory The memory allocated to the MetaDB. Default value: 90G.root@sys Password The password of the root user of the sys tenant. After you set the parameters, click Submit.
You can also click Reset to restore the default configurations.
