Hello Vincent, yes we tried Oracle10gDialect. In this case the get the
Error number 3202 in 3: Exception while reading document [xwiki:AnnotationCode.AnnotationConfig] Caused by: com.xpn.xwiki.XWikiException: Error number 3301 in 3: Exception while switching to database xwiki Caused by: org.hibernate.QueryTimeoutException: error executing work Caused by: java.sql.SQLException: ORA-01435: *Benutzer ist nicht vorhanden.* The bold error message says *User does not exists * But we are sure we used a correct connection string. Because were able to connect from the server to our Database using the same connection string via sqlplus. Our concluse is that there is a problem using the Oracle10gDialect with a 12c Oracle Database. thank you for your help. best regards Bastian -- View this message in context: http://xwiki.475771.n2.nabble.com/Does-XWIKI-Support-Oracle12c-tp7595891p7595919.html Sent from the XWiki- Users mailing list archive at Nabble.com. _______________________________________________ users mailing list users@xwiki.org http://lists.xwiki.org/mailman/listinfo/users
