oracle em 性能点不进,oracle em节点启动不成功问题处理总结
客戶數據庫項目從oracle 9i數據庫升級到oracle10g后，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.查看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
顯示沒有運行。
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
重建后還是錯誤提示一樣。
4.安裝8350262補丁
安裝8350262補丁后,問題還是一樣，節點1em依舊啟動不成功。
5.尋求oracle技術支持,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
通過掉oc4j進程，
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技術支持，包括開tar,發貼等。
