6、RMAN> restore spfile from '/u01/app/oracle/flash_recovery_area/ORCL/autobackup/2010_10_17/o1_mf_s_732633337_6cpcsv2b_.bkp';
恢复old spfile时RMAN-06564: must use the TO clause when the instance is started with SPFILE
解决办法：指定to cluase即可

1、
RMAN> duplicate target database to orcl;--用于复制数据库/duplicate target database for standby;--用于生成standby库

Starting Duplicate Db at 17-OCT-10
using target database control file instead of recovery catalog
allocated channel: ORA_AUX_DISK_1
channel ORA_AUX_DISK_1: sid=155 devtype=DISK
RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============
RMAN-00571: ===========================================================
RMAN-03002: failure of Duplicate Db command at 10/17/2010 11:56:34
RMAN-05501: aborting duplication of target database
RMAN-05001: auxiliary filename /u01/app/oracle/oradata/orcl/users01.dbf conflicts with a file used by the target database
RMAN-05001: auxiliary filename /u01/app/oracle/oradata/orcl/sysaux01.dbf conflicts with a file used by the target database
RMAN-05001: auxiliary filename /u01/app/oracle/oradata/orcl/undotbs01.dbf conflicts with a file used by the target database
RMAN-05001: auxiliary filename /u01/app/oracle/oradata/orcl/system01.dbf conflicts with a file used by the target database
RMAN-05001: auxiliary filename /u01/app/oracle/oradata/orcl/redo03.log conflicts with a file used by the target database
RMAN-05001: auxiliary filename /u01/app/oracle/oradata/orcl/redo02.log conflicts with a file used by the target database

如果在RMAN恢复时不指定 nofilenamecheck 参数
则在db_file_name_convert or log_file_name_convert中源、目的数据文件（参数值）相同是做恢复会出现RMAN-05501错误
2、
RMAN> duplicate target database to orcl;

RMAN-03002: failure of Duplicate Db command at 10/17/2010 11:02:08
ORA-01405: fetched column value is NULL

解决办法： alter　system switch logfile

3、

contents of Memory Script.:
{
   Alter clone database open resetlogs;
}
executing Memory Script
。。不动了
解决。。给每个日志文件至少一次归档

 
4、
DGMGRL> add database orcl as 
> connect identifier is orcl
> maintained as physical;
Error: ORA-16642: db_unique_name mismatch
 
主库 和备库的db_unique_name不能一样
5、dg switch to norcl后
SQL> alter database open;
alter database open
*
ERROR at line 1:
ORA-16649: database will open after Data Guard broker has evaluated Fast-Start
Failover status

解决：首先检查listener是否正常
cli 查看configuration中fast_start failover是否enable 都具备则不需做什么
Cause: The database is being opened while Fast-Start failover is enabled. The message indicates that the Data Guard broker will first determine if conditions are suitable for opening; that is, a Fast-Start failover did not occur while the database was unavailable.
Action: No action is normally required. The Data Guard broker will continue opening the database after determining a Fast-Start failover did not occur. If there is a chance that a Fast-Start Failover did occur, the database will remain in the mounted state and will not open. In this case, check the target standby to see if a role transition took place.
