在使用RMAN创建STANDBY数据库的过程中，连接AUXILIARY的时候报错。

详细错误信息如下：

[oracle@yangtk ~]$ rman target / auxiliary sys/test@172.25.4.70/ora11g

Recovery Manager: Release 11.1.0.6.0 - Production on Wed Nov 7 01:45:35 2007

查询了一下METALINK，发现这个问题从9i到11g，任何一个版本都可能会出现。造成这个问题的原因是，实例虽然启动，但是没有注册到监听。实例是通过PMON进程注册到监听上的，而PMON进程需要在MOUNT状态下才会启动。因此造成了上面的错误。

Oracle给出了两种解决方案，一种方法是对AUXILIARY数据库直接使用/，对TARGET数据库通过网络访问。

[oracle@yangtk2 ~]$ rman target sys/test@172.25.4.127/ORA11G_P.ytk-thinkpad auxiliary /

RMAN>

第二种方法为AUXILIARY数据库设置静态监听，在$ORACLE_HOME/network/admin目录下的listener.ora中添加下面的内容：

SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = ora11g)
(ORACLE_HOME = /data/oracle/product/11.1)
)
)

重启监听：

[oracle@yangtk2 admin]$ lsnrctl stop

在TARGET服务器上再次尝试登陆：
