PHP 4 is no longer supported. MySQL is the recommended DBMS. PostgreSQL or SQLite can also be used, but support for them is somewhat less mature. There is experimental support for IBM DB2 and Microsoft SQL Server. The supported versions are: * MySQL 4.0 or later * PostgreSQL 8.3 or later * SQLite 3 * Oracle 9.0.1 or later == Upgrading == 1.19 has several database changes since 1.17, and will not work without schema updates. If upgrading from before 1.11, and you are using a wiki as a commons repository, make sure that it is updated as well. Otherwise, errors may arise due to database schema changes. If upgrading from before 1.7, you may want to run refreshLinks.php to ensure new database fields are filled with data. If you are upgrading from MediaWiki 1.4.x or earlier, some major database changes are made, and there is a slightly higher chance that things could break. Don't forget to always back up your database before upgrading! See the file UPGRADE for more detailed upgrade instructions.
