standby库，在sqlplus下用recover standby database进行手工恢复

一个standby库出问题，丢了1个归档
检查主库的日志，发现丢失的归档的SEQ的redo还未被覆盖，马上将其拷贝出来传递到备库上

尝试catalog，虽然没有报错，但是实际没有注册成功
RMAN> catalog archivelog '/u01/app/oracle/oradata/ORCL/redo03_281.arc';                    

cataloged archived log
archived log file name=/u01/app/oracle/oradata/ORCL/redo03_281.arc RECID=297 STAMP=840464160

尝试使用sqlplus的recover命令来恢复，提示是standby controlfile，无法进行
SQL> recover database ;
ORA-00283: recovery session canceled due to errors
ORA-01610: recovery using the BACKUP CONTROLFILE option must be done

SQL> recover database using backup controlfile;
ORA-00283: recovery session canceled due to errors
ORA-01666: control file is for a standby database

没找到sqlplus下recover命令的reference，最后瞎尝试，总算试了出来
SQL> recover standby database;                                                     <==
ORA-00279: change 1728518 generated at 06/08/2013 20:13:37 needed for thread 1

cancel

恢复该归档后，DG恢复正常。

其实，还有个解决办法，从主库生成一个控制文件备份过来，用该控制文件mount库，就可以用recover database using backup controlfile进行恢复
这个案例中可以看到，redo log拷贝出来后，是无法作为archivelog给catalog进控制文件的
