5 XWiki uses by default a database to store its data. You will find on this page tips and tricks to administer and tune your database setup. For Installation please check the [[Installation guide>>InstallationWAR#HInstallandconfigureaRelationalDatabase]] which contains information on how to setup XWiki for multiple databases.

61 * Most indexes are created automatically starting with XWiki Enterprise 3.2 and only the indexes listed above need to be created.
62 * For older versions every index must be created manually. You can see the full list of indexes that should be created for older versions below. There is now [[an application>>extensions:Extension.Check Config And Indexes Application]] that runs this script automatically on XE and XEM directly from your wiki.

153 = Sanity Checks =
154
155 To verify the consistency of your XWiki database you can run the sanity check script. The script will select rows that are inconsistent with the logics of XWiki. If no rows are selected, it means the script itself can not detect any error.
156
157 * If you use **MySQL** as your database:
158 ** The following [[sanity check script>>attach:sanitycheck.sql]] has been tested for **MySQL 5.0** (also been reported to work with MS-SQL)
159 ** Another [[script>>attach:sanitycheckMySQL4.sql]] is a variant of the previous script for **MySQL 4.x** replacing some syntax with more ancient one (still reports errors in one command)
160 * If you use **postgresql** as your database:
161 ** Here is a [[modified version of the sanity check script>>attach:sanitycheck_postgresql.sql]], to be run in the "query" tool of pgAdmin. It is the same as the script for MySQL, except that the syntax for SQL comments is different.
162 ** pgAdmin is the GUI tool provided with postgresql to access the database. Run pgAdmin, select the ##xwiki## database, and choose the "Query" option in the "Tools" menu. Then just open the script and click on the play icon ("Execute query").
