The Confluence installation includes a pre-configured HSQLDB database for evaluation purposes only. For safe production use, you need to configure Confluence to use an external database listed below.
Supported Databases

Confluence supports the following database systems, provided they are running on a Windows, Unix (NetBSD, FreeBSD, OpenBSD, Solaris, Linux), Mac OS X on X86 or X86-64 processors.

  Supported in Confluence 2.9 (AUG/2008)
Works with Confluence 2.9
PostgreSQL 8.1, 8.2 8.0, 8.3
Oracle 10.1, 10.2 11
MySQL 5.0.28 and above
4.1, 5.0 - 5.0.27
DB2 8.2  
SQL Server 2005  

Column labelled 'Works with' as opposed to 'Supported in': We assume that Confluence works fine with these database versions. But please be aware that we don't test these versions regularly and that we may ask you to upgrade to a supported platform before we can provide more detailed support.

If your database does not appear on this list, please read the questions and answers about supported platforms.

For Confluence 2.8 and later, zOS, AIX and HPUX are not supported; neither are processors other than X86. If you can get these databases running on another operating system or other processors, we will try to help you but may ask you to move to a supported operating system before we can provided more detailed support. Please note that DB2 on AS/400 or iSeries is not supported, and DB2 on OS/390 or z/OS is not supported either. Some customers have reported getting this working — you can find the details of their unsupported work around in CONF-11125.

If you have no preference, we recommend using MySQL — it is scalable, free, and easy to set up. For database setup information, see Database Configuration.

The following databases work with some workarounds and are supported for versions up to Confluence 2.7, and probably still work with Confluence 2.8. However they are no longer officially supported from Confluence 2.8 on.

  • PostgreSQL 7.1
  • Oracle 8i, 9i
  • Microsoft SQL Server 2000
  • Sybase ASE 12.5.1

Refer to the list of known issues for these databases.

Advance Notice

The next major release of Confluence after 2.9 will not officially support the following versions of database systems any more. We may still test those versions infrequently, and Confluence will probably still work fine with them for a while, but they will be not officially supported:

  • MySQL 4.1.x — please upgrade to MySQL 5
