Take over NLB

This topic describes how to take over NLB 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 NLB, make sure that the following conditions are met:

• You have added the image used by NLB.
• You have installed OAT and logged on as either a super administrator or an O&M engineer. For more information, see Install OAT.
• You have added a server where NLB is to be installed. For more information, see Add a server.
• The server meets the requirements for installing NLB.

Procedure

To install NLB, perform the following steps:

1. In the left-side navigation pane, choose Product Service > Component Management.

2. On the Component Management page, click Take Over Component in the upper-right corner, and choose Take Over NLB.

3. On the Take Over NLB page, configure the parameters.

   The following table describes the basic parameters of NLB.

   Parameter	Description
   NLB Image	The Docker image of NLB.
   Component Name	The name of the component, which must be unique. Default value: NLB.
   Server	The IP address of the server where NLB is to be installed.
   CPU	The number of CPU cores on the server available for NLB. Default value: 32C.
   Memory	The memory on the server available for NLB. Default value: 90G.

4. After you set the parameters, click Submit.

   You can also click Reset to restore to the default configurations.

What to do next

After you take over NLB, you can take over other products. For more information, see Take over products.
