升級xwiki（2.5至4.4）

Question

即時通訊使用XWIKI ENTERPRISE 2.5並且想升級到4.4或4.3（穩定） 我發現this upgrade documentation for XWiki。遵循指南，我備份了WEB-INF中的重要文件。 之後，我將新的.war的所有文件複製到我的wiki目錄（/var/lib/tomcat6/webapps/xwiki）。然後，我移回重要文件並覆蓋新文件。

我收到此錯誤信息，當我訪問我的wiki頁面：

HTTP Status 404 - type Status report 
message description 
    The requested resource() is not available. 
Apache Tomcat/6.0.28 

這裏是日誌文件：

Answer 1

當你說

我複製了所有的從新的.war文件到我的wiki目錄

您是否將的新文件複製到的現有目錄中？您應該刪除舊版本中的所有內容，並僅使用新版本中的文件，並僅從備份中複製基本配置文件。此外，請注意，您不應只複製舊配置，但會將您的自定義設置合併爲到默認的新配置中。

在堆棧跟蹤根錯誤：

Caused by: org.infinispan.jmx.JmxDomainConflictException: Domain already registered org.xwiki.infinispan 

建議重複罐子。另一種情況是，如果在同一個容器中有多個XWiki實例，則應該編輯WEB-INF/cache/infinispan/config.xml，並用一個唯一值替換行jmxDomain="org.xwiki.infinispan"，如jmxDomain="org.xwiki.infinispan.wiki1"和jmxDomain="org.xwiki.infinispan.wiki2"這兩個實例。

Answer 2

從4.0-rc-1升級到4.4或4.5時，我一直有同樣的問題。我沒有重複的罐子，也沒有運行XWiki的幾個實例。無論是在infinispan還是在XWiki的緩存實現中都可能存在問題。

暫時的解決辦法是明確允許重複域config.xml中：

<globalJmxStatistics 
    [...] 
    allowDuplicateDomains="true" />
