OceanBase Admin Toolkit (OAT) allows you to modify the configurations of node resources for services and components that are in use. For example, you can add, remove, or replace nodes based on resource environment changes.
Overview
| Resource change type | Description |
|---|---|
| Add a node | You can add nodes to improve service performance or availability. |
| Remove a node | You can remove existing nodes to reduce resource usage of services. |
| Replace a node | You can replace damaged nodes or those no longer in use to improve service stability. |
You can make changes to the following products, components, and tools:
| Type | Name |
|---|---|
| Product | OCP, ODC, OMS, OAS, and OB Sharding |
| Component | MetaDB, OBDNS, NLB, SQLAuditStore, and Arbitration Service |
| Tool | OBLB, OBClient, OpsToolkit, SQL Diagnoser, Obdiag, OB-Loader-Dumper, Sysbench, and OBLENS |
Procedure
To change the resources of a service or component, perform the following steps:
In the left-side navigation pane, choose Product Service > Products or Product Service > Components.
On the Products or Components page, find the service or component whose resources you want to change and click its name to go to the details page.
On the details page, click Resource Change.
After you change the resources, click OK.
You can also click Cancel to cancel the changes.
