2，解决方案：将主库的密码文件 copy到备份库，然后重启备份库，解决。

3，恢复过程：
再启动从库
STARTUP MOUNT;
再应用redo应用
alter database recover managed standby database disconnect from session;
查看是否有yes
select name,sequence#,applied from v$archived_log;  


再去主库上切换下日志，看下新的24178归档日志是否传输过来，是否应用成YES：
alter system switch logfile;
SQL> alter system switch logfile;                                                                                                                                                              
System altered.
SQL> 


去从库上面执行检查
SQL> select sequence#,applied from v$archived_log;
 SEQUENCE# APPLIED
---------- ---------
     24170 YES
     24169 YES
     24173 YES
     24176 YES
     24177 YES
     24178 IN-MEMORY


2800 rows selected.
再继续检查check下，applied就变成YES了
 SEQUENCE# APPLIED
---------- ---------
     24170 YES
     24169 YES
     24173 YES
     24176 YES
     24177 YES
     24178 YES
2800 rows selected.


停止redo应用
alter database recover managed standby database cancel;
再打开open模式，将从库打开供大家查询数据
alter database open read only;
再起动redo应用
alter database recover managed standby database disconnect from session;
