3. 日志报secure agent时错：
WARNING: Error executing /oracle/app/oracle/product/11.2.0.3/dbhome_1/bin/emctl secure dbconsole -host rac1 -sid racdb
Nov 23, 2011 2:56:48 PM oracle.sysman.emcp.util.DBControlUtil secureDBConsole
WARNING: Error securing Database Control for node rac1.
4.重新运行emca -config dbcontrol db -repos recreate -cluster，结果还是相同的错误
5.检查secure.log中的日志，报Failed to stop agent...

6.手工执行/oracle/app/oracle/product/11.2.0.3/dbhome_1/bin/emctl secure dbconsole -host rac1 -sid racdb
也是报Failed to stop agent...

7.杀掉节点2 agent 进程，重新运行第6步，还是一样的错误
8.根据第2步中的日志提示先执行以下脚本
/oracle/app/oracle/product/11.2.0.3/dbhome_1/bin/emctl config emkey -repos -sysman_pwd oracle -host rac1 -sid racdb
/oracle/app/oracle/product/11.2.0.3/dbhome_1/bin/emctl secure dbconsole -sysman_pwd oracle -host rac1 -sid racdb

10.查看emdctl.trc，报以下错误

11.根据"Returning status code 2"关键字查找MOS，找到1292074.1，里面提到可能的原因是"etc/hosts file was not in the correct format."
12.查看/etc/hosts文件

16.加密也成功了，可以通过https://rac1:1158/em/正常访问
总结：
1.碰到任何问题都要先看仔细的日志，不要漏过任何信息，然后根据日志一步一步的分析，不要盲目的处理。
2./etc/hosts文件中不要不留无用的条目 ，碰到一些问题棘手问题的时候检查一下hosts配置是否正确
