使用RMAN验证备份的有效性

--验证控制文件和参数文件：
RMAN> restore validate controlfile;

Starting restore at 22-JUL-14
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=36 device type=DISK

channel ORA_DISK_1: starting validation of datafile backup set
channel ORA_DISK_1: reading from backup piece /u01/backup/fullbak_ORACLE_20140722_5_1
channel ORA_DISK_1: piece handle=/u01/backup/fullbak_ORACLE_20140722_5_1 tag=TAG20140722T095956
channel ORA_DISK_1: restored backup piece 1
channel ORA_DISK_1: validation complete, elapsed time: 00:00:02
Finished restore at 22-JUL-14

RMAN> restore validate spfile;

Starting restore at 22-JUL-14
using channel ORA_DISK_1

channel ORA_DISK_1: starting validation of datafile backup set
channel ORA_DISK_1: reading from backup piece /u01/backup/fullbak_ORACLE_20140722_6_1
channel ORA_DISK_1: piece handle=/u01/backup/fullbak_ORACLE_20140722_6_1 tag=TAG20140722T095956
channel ORA_DISK_1: restored backup piece 1
channel ORA_DISK_1: validation complete, elapsed time: 00:00:02
Finished restore at 22-JUL-14

--验证全备份 一般会很慢
RMAN>  restore validate database;
