使用emca命令列配置EM並通過瀏覽器訪問EM示例
EM是Oracle Enterprise Manager簡稱，本文涉及操作及命令：
配置EM-建立刪除重建: emca -config dbcontrol db -repos recreate|drop|create
啟動、關閉、檢視EM狀態 emctl start|stop|status dbconsole
環境：OEL5.7,ORACLE 11.2.0.4,VBOX虛擬機器
配置EM前檢查事項：1.確定監聽已經啟動並正常執行，2.檢查主機名 3.檢查主機名與IP對應已經寫入/etc/hosts，4.密碼檔案進行確認無誤，5.檢查EM需要用到的三個使用者：SYS DBSNMP,SYSMAN的密碼以及是否能登陸，6.可以提前將 $ORACLE_HOSTNAME變數（與主機名一致即可）寫入.bash_profile.這個引數不寫有時也可以，保險起見還是寫上吧。7.可使用SYS使用者通過服務名登陸資料庫測試一下。
