查詢日誌檔案 ：

[[email protected] log]# find /oracle/ -name oraagent_grid.log
/oracle/app/11.2.0/grid/log/itpux1/agent/crsd/oraagent_grid/oraagent_grid.log
/oracle/app/11.2.0/grid/log/itpux1/agent/ohasd/oraagent_grid/oraagent_grid.log

#more oraagent_grid.log

此問題是因：/etc/hosts檔案配置錯誤，新增

127.0.0.1 localhost  

即可！
