Database Configuration
This document provides information on connecting Confluence to an external database.
Choosing an external database
Note: Take time to choose your database wisely. The XML backup built into Confluence is not suited for migration or backup of large data sets. If you need to migrate later, you may need to use a third party database migration tool.
Below is more information on selecting and migrating to an external database:

Database setup
To find out how to set up your database, see:
- Database Setup for Oracle
- Database Setup For MySQL
- Database Setup for PostgreSQL
- Database Setup for SQL Server

H2 database for development only
We no longer support use of H2 database for production environments. If you wish to continue using the H2 embedded database for testing and app development on non-clustered (single node) installations only, make sure you're using AMPS 8.6.0.
To find out if you are still using the embedded database, go to 
> General Configuration > Troubleshooting and support tools.
Database drivers
You must use a supported database driver. See Database JDBC Drivers for the drivers we support.
If you attempt to use an unsupported or custom JDBC driver (or a driverClassName from an unsupported or custom driver in your JNDI datasource connection) collaborative editing will fail.
Database connection method
You should connect Confluence to your database using a JDBC URL. The Confluence setup wizard only provides this option as JDBC connection is the recommended method.
