Hi! In a XE/XEM 2.4.1 farm, our Lucene building index process stopped as ... *Lucene is currently building its index, 41 documents in queue. *And we can't access Search in XWiki Preferences of any of the subwikis or even the controller.* * I see this in xwiki.log: com.xpn.xwiki.XWikiException: Error number 3301 in 3: Exception while switching to database redpatrimonio Wrapped Exception: Unknown database 'redpatrimonio' at com.xpn.xwiki.store.XWikiHibernateBaseStore.setDatabase(XWikiHibernateBaseStore.java:643) at com.xpn.xwiki.store.XWikiHibernateBaseStore.beginTransaction(XWikiHibernateBaseStore.java:742) at com.xpn.xwiki.store.XWikiHibernateStore.loadXWikiDoc(XWikiHibernateStore.java:683) at com.xpn.xwiki.store.XWikiCacheStore.loadXWikiDoc(XWikiCacheStore.java:289) at com.xpn.xwiki.XWiki.getDocument(XWiki.java:1463) at com.xpn.xwiki.XWiki.getDocument(XWiki.java:1506) at com.xpn.xwiki.api.XWiki.getDocument(XWiki.java:166) at com.xpn.xwiki.api.XWiki.getDocument(XWiki.java:153) at com.xpn.xwiki.plugin.lucene.SearchResult.<init>(SearchResult.java:98) at com.xpn.xwiki.plugin.lucene.SearchResults.getRelevantResults(SearchResults.java:72) at com.xpn.xwiki.plugin.lucene.SearchResults.getHitcount(SearchResults.java:22 In fact, that database is called redepatrimonio, not redpatrimonio. The wiki descriptor page name in the main wiki is XWiki.XWikiServerRedepatrimonio. Please, where the name of the database as listed in the exception is stored? How could I correct it? I don't know how I've messed things and if this error is related with problem, but it seems that need to be corrected before trying anything else! Thanks! Ricardo -- Ricardo RodrÃguez CTO eBioTIC.
