Install OMA

Last Updated:2026-09-04 08:16:35

This topic describes the basic configuration requirements for installing OceanBase Migration Assessment (OMA) and how to deploy and use it.

Basic configuration requirements

The server where OMA is to be installed must have at least eight logical CPU cores and 16 GB of memory.

If many objects are to be assessed, we recommend that you increase the resource configuration and disk space on the server.
At least 2 GB of disk space is required.

Note

If a large number of objects are to be assessed, ensure the disk space is sufficient for the assessment reports.
Java 1.8 must be installed in the system.
We recommend that you run this program on Linux or macOS.
To connect OMA to a database, make sure that the server where OMA is installed can access the source database.

You can directly decompress the downloaded package without installing a CLI tool.
Download the OMA package, decompress it, and go to the directory where OMA is located.
```
tar zxvf oma-x.x.x.tar.gz
cd oma-x.x.x
```
Run the corresponding script and specify the parameters required for assessment. Then, you can use OMA to perform an assessment. For more information about the parameters, see Product form.
- In Microsoft Windows, run start.bat.
- In Linux, run bin/start.sh.
