提示说明找不到rac1 节点的密码文件,查看节点rac1上的存在orapwrac1 和orapwrac2文件，而节点rac2上不存在

解决办法

将节点rac1上的密码文件orapwrac1拷贝到节点rac2上

#scp orapwrac1 10.250.7.241:/opt/oracle/11.2.0/alifpre/

这里遇见 ORA-00845，因为目标库上运行了两个数据库，内存空间不足，导致 ORA-00845！

解决办法：关闭另外一个数据库实例。

ORA-16032: parameter  destination string cannot be translated

PING[ARC2]: Heartbeat failed to connect to standby 'yangdb'. Error is 16032.

原因：目的参数无法解析。查看了mos文档，次错误与备库的standby_archive_dest的设置方式有关

解决方法：

SQL> show parameter standby 

NAME                             TYPE         VALUE

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

standby_archive_dest             string   location=/opt/rac/oracle/arch

standby_file_management          string   MANUAL

SQL> alter system set standby_archive_dest='/opt/rac/oracle/arch' scope=both sid='*';

System altered.

SQL> show parameter standby 

NAME                      TYPE        VALUE

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

standby_archive_dest     string      /opt/rac/oracle/arch

standby_file_management  string      MANUAL

再次执行，问题解决。。
