Overview

This topic describes the precautions and methods for deploying OceanBase Migration Service (OMS) Community Edition of the current version.

Deploy OMS Community Edition on a single node

OMS deployed on a single node can provide all OMS Community Edition features. If you do not need to use a high-availability environment, you can deploy OMS Community Edition on a single node. For more information, see Deploy OMS Community Edition on a single node.

Deploy OMS Community Edition on multiple nodes in a single region

You can deploy OMS Community Edition on multiple nodes to achieve high availability (HA). In the HA deployment architecture, each OMS Community Edition node provides all OMS features, and the backend task framework implements distributed scheduling based on the database. When an OMS Community Edition node becomes unavailable, the framework automatically schedules tasks to other available OMS Community Edition nodes. OMS Community Edition Community Edition also supports the deployment on multiple nodes in a single region. For more information, see Deploy OMS Community Edition on multiple nodes in a single region.

Note:

HA does not enable the automatic restoration of the checker.

We recommend that you apply multi-node deployment in the production environment.

Deploy OMS Community Edition on multiple nodes in multiple regions

OMS Community Edition supports multi-region deployment. You can deploy OMS Community Edition across multiple regions. For more information, see Deploy OMS Community Edition on multiple nodes in multiple regions.

Precautions

• If you use OMS Community Edition to collect and display historical monitoring data, you need to deploy an InfluxDB database.

• By default, HA is disabled in OMS Community Edition. To enable HA, go to the OMS Community Edition console, find the ha.config parameter, and set the enable parameter to true. For more information, see Modify HA configurations.
