1          问题描述

客户数据库项目从oracle 9i数据库升级到oracle10g后，oracle em在节点1启动不成功，节点2可以正常启动。

节点1启动时报错如下:

  [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.

https://zhgsdb1:5502/em/console/aboutApplication

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

[oracle@zhgsdb1 ~]$

2          处理过程

1.  查看em的状态

 [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.

https://zhgsdb1:5502/em/console/aboutApplication

Oracle Enterprise Manager 10g is not running.

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

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

   显示没有运行。

2.  尝试关闭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.

提示关闭失败。
    

3.  重建EM

重建后还是错误提示一样。

4.  安装8350262补丁

安装8350262补丁后,问题还是一样，节点1em依旧启动不成功。

5.  寻求oracle技术支持,开tar

Oracle的建议是:

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

通过掉oc4j进程，

em在节点1可以正常启动。

em使用正常。

3          结论和建议

遇到些自己解决不了的问题，可以寻求oracle技术支持，包括开tar,发贴等。
