Openfire stores all data in a back-end database. If you choose to not use the embedded database, you must setup and manage an external database for the application. This document provides setup instructions for all of the currently supported databases.

JDBC 2.0 drivers are required for Openfire to communicate with your database. Suggested drivers for particular databases are noted below where applicable. Openfire bundles JDBC drivers for MySQL, Postgres, Microsoft SQL Server, and HSQLDB.
