在cloudfoundry上部署xwiki

Question

嘗試將最新的xwiki（xwiki-enterprise-web-4.1-milestone-2）war文件部署到cloudfoundry（無需耦合到MySql數據庫）並獲得奇怪的錯誤（在控制檯中，嘗試啓動xwiki STS）：

java.io.FileNotFoundException: /var/vcap/data/dea/apps/politic-xwiki-0-4aa67856cdca2e052aea5e0761b23636/tomcat/../tomcat.state (Too many open files)

Answer 1

在打開的文件太多的問題之前已經在Cloud Foundry上forums提高。

我已使用方法概述here之前（在我的微型雲代工廠實例）解決此問題。

您需要編輯/var/vcap/packages/dea/dea/lib/dea/agent.rb以增加打開的文件限制。您可以按照Martin Englund在其論壇post中所述的方式執行此操作。很明顯，您無法在CloudFoundry.com上執行此操作。

希望這會有所幫助。
