嘗試用系統管理員身份登錄數據庫，但是失敗
-bash-4.1$ sqlplus / as sysdba
-bash: sqlplus: command not found
-bash-4.1$ more ~/.bash_profile
/home/oracle/.bash_profile: 權限不夠
檢查/home/oracle權限，發現所有者是root
-bash-4.1$ ll /home

問題的原因基本確定，/home/oracle的所有者變成root，這問題也許是某個用戶的誤操作造成的。
將oracle的用戶根目錄和oracle的安裝目錄的所有者設置成oracle，用戶組爲oinstall之後問題解決。
