客戶資料庫專案從oracle 9i資料庫升級到oracle10g後，oracle em在節點1啟動不成功，節點2可以正常啟動。

節點1啟動時報錯如下:

  [oracle@zhgsdb1 ~]$ emctl start dbconsole

TZ set to PRC

Oracle Enterprise Manager 10g Database Control Release 10.2.0.5.0 

Copyright (c) 1996, 2010 Oracle Corporation.  All rights reserved.

 - An instance of Oracle Enterprise Manager 10g Database Control is already running.

[oracle@zhgsdb1 ~]$

1.  檢視em的狀態

 [oracle@zhgsdb1 ~]$ emctl status dbconsole

TZ set to PRC

Oracle Enterprise Manager 10g Database Control Release 10.2.0.5.0 

Copyright (c) 1996, 2010 Oracle Corporation.  All rights reserved.

Oracle Enterprise Manager 10g is not running.

------------------------------------------------------------------

Logs are generated in directory /oracle/app/oracle/product/10.2/zhgsdb1_CTAIS1/sysman/log

   顯示沒有執行。

2.  嘗試關閉em

[oracle@zhgsdb1 ~]$ emctl stop dbconsole

TZ set to PRC

Oracle Enterprise Manager 10g Database Control Release 10.2.0.5.0 

Copyright (c) 1996, 2010 Oracle Corporation.  All rights reserved.

Stopping Oracle Enterprise Manager 10g Database Control ...

--- Failed to shutdown DBConsole Gracefully ---

 failed.

提示關閉失敗。
    

3.  重建EM

重建後還是錯誤提示一樣。

4.  安裝8350262補丁

安裝8350262補丁後,問題還是一樣，節點1em依舊啟動不成功。

5.  尋求oracle技術支援,開tar

Oracle的建議是:

On both nodes
1) emctl stop dbconsole
2) ps -ef | grep OC4J ==> kill any processes found related to this dbcontrol
3) ps -ef | grep agent ==> kill any process found related to dbcontrol's agent

透過掉oc4j程式，

em在節點1可以正常啟動。

em使用正常。

3          結論和建議

遇到些自己解決不了的問題，可以尋求oracle技術支援，包括開tar,發貼等。
