我們的ORA-07445，根據DUMP檔案分析，多半是因為亂碼問題照成的，然後修改了伺服器的字元集。（即添加export NLS_LANG=AMERICAN_AMERICA.ZHS16GBK）。然後跟進我們這個包MONITOR.PACKAGE_GARBAGEDISTRIBUTING。一切OK了。

總結：亂碼問題也可以導致ora-07445問題。遇到問題沉著冷靜，細心才可以把問題解決好。

  天哪，真是DEBUG狀態！
   一個因為在DEBUG狀態，且是基於DELETE的TRIGGER觸發了這個Oracle的BUG！
    ......
   現在要麼改這個TRIGGER的狀態，要麼打補丁（9.2.0.6）。第一種選擇是明智而快捷且安裝的。重新編譯，檢查不是DEBUG狀態。應用啟動，正常運行
