将备份集重新注册到控制文件
因为之前备份集的位置发生改变，导致corsscheck之后，将之前备份的记录标记为expired，我们后来手工删除了这些expired的备份集信息。
现在我们要进行恢复，必须将之前的备份信息重新注册到控制文件中来。
方法一：注册单个备份片
RMAN> CATALOG BACKUPPIECE '/u01/bak/arch_0no76njh_1_1_20130416','/u01/bak/ctl_file_0oo76njm_1_1_20130416';
cataloged backup piece
backup piecehandle=/u01/bak/arch_0no76njh_1_1_20130416 RECID=25 STAMP=812872014
cataloged backup piece
backup piece handle=/u01/bak/ctl_file_0oo76njm_1_1_20130416RECID=26 STAMP=812872014
--可以正常查看：
RMAN> list backupset summary;
List of Backups
===============
Key TY LV S Device Type Completion Time #Pieces #Copies Compressed Tag

25 B A A DISK 16-APR-13 1 1 NO ARC_BAK
26 B F A DISK 16-APR-13 1 1 NO BAK_CTLFILE
RMAN> catalog start with'/data01/';
方法二：注册整个目录
---ASM:
CATALOG START WITH '+disk'; # catalog allfiles from an ASM disk group
--本地目录：最后一定要加/
CATALOG START WITH '/fs1/datafiles/'; #catalog all files in directory
--有多个目录，注册多次：
RMAN> catalog start with'/data01/';
RMAN>catalog start with '/data02/';
RMAN>catalog start with '/data03/';
