Manuel Smeria 27.2 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.

Manuel Smeria 27.2 9 To improve the performance of your XWiki instance when running with many documents you should run the following script to create indexes for your database (this has been tested for MySQL 5.0):

Manuel Smeria 27.2 33 * Most indexes are created automatically starting with XWiki Enterprise 3.2 and only the indexes listed above need to be created.
34 * 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.

Ludovic Dubost 1.1 126
jeanvivienmaurice 1.6 127 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.
jeanvivienmaurice 1.7 128
Manuel Smeria 27.2 129 * If you use **MySQL** as your database:
130 ** The following [[sanity check script>>attach:sanitycheck.sql]] has been tested for **MySQL 5.0** (also been reported to work with MS-SQL)
131 ** 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)
132 * If you use **postgresql** as your database:
Silvia Macovei 19.1 133 ** 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.
Vincent Massol 22.2 134 ** 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").
