It is not related to the installation or setup of MediaWiki. |

The <code>DatabaseDomain</code> class can extract such components from a database domain ID. |
| − | * | + | * If you configure <code>$wgDBservers</code> or <code>$wgLBFactoryConf</code>, you still need to define <tvar|3><code>$wgDBname</code>, <tvar|4><code>$wgDBmwschema</code> (if applicable for the DB type), and <tvar|5><code>$wgDBprefix</code> (if applicable for the DB type). The combination of <code>$wgDBname</code>, <code>$wgDBmwschema</code>, and <tvar|3><code>$wgDBprefix</code> define the current wiki's ''database domain''. This is also called the ''local database domain''. The 'dbname' and 'tablePrefix' settings in <tvar|3><code>$wgDBservers</code> and <tvar|4><code>$wgLBFactoryConf</code> only define the default DB/prefix when a connection is requested with <tvar|5><code>DatabaseDomain::newUnspecified()->getId()</code> (the empty string) as the database domain, e.g. <tvar|6><code>wfGetDB( DB_REPLICA, [], <nowiki>''</nowiki> )</code>. Note that functions calls like <code>wfGetDB( DB_REPLICA )</code>, which simply omit the database domain, are assumed to refer to the local database domain. |
