Oracle em 無法啟動,報not found錯誤

Oracle 11g r2安裝完，建完庫之後，啟動em 報OC4J_DBConsole_source_ora11g not found的錯誤，em起不來。

[oracle@source ~]$ emctl start dbconsole

 OC4J Configuration issue. /oracle/product/10.2.0/db_1/oc4j/j2ee/OC4J_DBConsole_source_ora11g not found.

由於是新環境，重新建立資料檔案庫，並重新設定資料庫control

[oracle@source admin]$ emca -repos drop --刪除當前的資料庫

emca -repos create: 建立新的 Database Control 資料檔案庫

emca -repos drop: 刪除當前的 Database Control 資料檔案庫

emca -repos recreate: 刪除當前的 Database Control 資料檔案庫並重新建立一個

emca -config dbcontrol db：設定資料庫的 Database Control

emca -deconfig dbcontrol db：取消資料庫的 Database Control

注:

（1）如果伺服器上存在多個資料庫，必須在啟動Database control之前設定ORACLE_SID環境變數.

（2）最好使用靜態IP地址來設定管理員.
