RMANORA-19693错误解决

10.2.0.5 on windows 64 bit 现象：从一个 server A拷贝backupset 至另一个server B。在server B上恢复。首先使用lsquo;catalog

10.2.0.5 on windows 64 bit

现象：从一个 server A拷贝backupset 至另一个server B。在server B上恢复。首先使用‘catalog start with ’编录backupset .

在恢复数据库的时候出现：

RMAN> restore database force;

Starting restore at 31-MAY-14
using channel ORA_DISK_1

channel ORA_DISK_1: starting datafile backupset restore
channel ORA_DISK_1: specifying datafile(s) to restore from backup set

ORA-19693: backup piece E:\BAK_04P9JK4Q_1_11 already included

在mos上找到如下文章：ID 288129.1提到恢复的时候backupset只能有一个copy

使用list backup summary:

RMAN> list backup summary;

List of Backups
===============
Key TY LV S Device Type Completion Time #Pieces #Copies Compressed Tag
------- -- -- - ----------- --------------- ------- ------- ---------- ---
4 B F A DISK 30-MAY-14 1 3 NO TAG201405
30T170010
5 B F A DISK 30-MAY-14 1 3 NO TAG201405
30T170010

使用RMAN> list backup of database tag=TAG20140530T170010;列出copies大于1的。

将磁盘的backupset重命名并删除多余的backup 再重新catalog即可。

两种情况：

1 实际backupset只有一份，由于多次catalog造成entries重复。

可以将backupset重命名，，重新catalog再crosscheck

备注：这里应该可以用其他方式删除entry??

2 实际backupset就有多分，删除多余backupset再crosscheck
