OAS的問題解決
某一天發現網站和後臺都無法登陸，重啓服務器後，ias後臺能進入，但是發現ias後臺的幾個服務無法正常啓動導致外網網站無法正常啓動。
異常如下圖：
再次選中以上的幾個服務啓動服務，發現home和CXSERVER無法啓動錯誤提示爲無法正常啓動，已經超過重試限制，查看日誌信息發現提示的error信息是關於servlet的信息。
遠程進入unix服務器進行調試，發現以oracle的用戶身份可以啓動以上的服務，啓動後一切正常。unix下的調試信息如下：
[cxias@cxwebserver app]$ cd OraHome_1/
[cxias@cxwebserver OraHome_1]$ ll
