实施DG利用RMAN恢复STANDBY数据库

RMAN> duplicate target database for standby nofilenamecheck dorecover;

Starting Duplicate Db at 28-MAR-12
using target database control file instead of recovery catalog
allocated channel: ORA_AUX_DISK_1
channel ORA_AUX_DISK_1: sid=155 devtype=DISK

contents of Memory Script.:
{
   set until scn  485861;
   restore clone standby controlfile;
   sql clone 'alter database mount standby database';
}
executing Memory Script

executing command: SET until clause

Starting restore at 28-MAR-12

出现了这个错误,很多人说是RMAN主库与备库目录不同导致的,但是我的目录是相同的。最后检查了一下备份的文件,发现了问题。

RMAN> restore controlfile validate;

Starting restore at 28-MAR-12
using channel ORA_DISK_1

RMAN-00571: ===========================================================
RMAN-00569: =============== ERROR MESSAGE STACK FOLLOWS ===============

RMAN-06024: no backup or copy of the control file found to restore

咱们备份的控制文件,有问题不能恢复了。所以重新换了全库备份脚本。检查了备份文件。都是可用的。然后把standby恢复了。
