各位好，我有个SUSE 11g SP1+ORACLE 11gR2+RAC的项目，现在RAC是搭建起来了，就是在配EM的时候老是报instance不可用，初步检查是监听配置的问题，但现在监听是正常工作的，PL/SQL连接也没有问题，因对11g R2 Grid 和Oracle用户的监听配置不是很了解，也多方请教了很多人远程协助过，都不能解决，如果您有时间，不知道方便帮我看看不，万分感谢了！
#emca -config dbcontrol db -cluster --报下面的错误：
Enter the following information:
Database unique name: racdb
Service name: racdb
