今天打算启用一下Oracle Database 11g的Database Control，发现初始并未安装:

[oracle@test126 ~]$ emctl start
EM Configuration issue. /opt/oracle/product/11.1.0/test126.hurray.com.cn_dodd not found.

 

遇到这类问题，可以通过重新配置，来创建EM的配置文件：

[oracle@test126 11.1.0]$ emca -config dbcontrol db -repos recreate

Oracle 10g中，配置方法与此相同。
配置完成之后就可以启动EM了：

[oracle@test126 11.1.0]$ emctl start dbconsole

如果是Linux环境，你可能还需要在iptables中开放1158端口，增加如下一行:
-A RH-Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 1158 -j ACCEPT

重新启动防火墙之后就可以通过IE在远端连接EM的Database Control了：

[root@test126 sysconfig]# service iptables restart
Flushing firewall rules: [ OK ]
Setting chains to policy ACCEPT: filter [ OK ]
Unloading iptables modules: [ OK ]
Applying iptables firewall rules: [ OK ]
