2，解決方案：將主庫的密碼檔案 copy到備份庫，然後重啟備份庫，解決。


參考文章地址：http://blog.itpub.net/26230597/viewspace-1224676/


3，恢複過程：
再啟動從庫
STARTUP MOUNT;
再應用redo應用
alter database recover managed standby database disconnect from session;
查看是否有yes
select name,sequence#,applied from v$archived_log;  


再去主庫上切換下日誌，看下新的24178歸檔日誌是否傳輸過來，是否應用成YES：
alter system switch logfile;
SQL> alter system switch logfile;                                                                                                                                                              
System altered.
SQL> 


去從庫上面執行檢查
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.
再繼續檢查check下，applied就變成YES了
 SEQUENCE# APPLIED
---------- ---------
     24170 YES
     24169 YES
     24173 YES
     24176 YES
     24177 YES
     24178 YES
2800 rows selected.


停止redo應用
alter database recover managed standby database cancel;
再開啟open模式，將從庫開啟供大家查詢資料
alter database open read only;
再起動redo應用
alter database recover managed standby database disconnect from session;
