内容简介：ORACLE 使用rman备份通过restore、recover恢复standby库ORA-10877实战

1、备库standby异常报错

昨天凌晨磁盘空间突然暴涨导致oracle备库异常，报警，后了过来清理掉磁盘的备份文件，去了之后，归档日志能同步过来了，但是启动备库standby发现mrp没有启动，后台报错如下，google了，说这种情况要重新再做备库（不知道是否还有其它修复办法呢？）：错误日志报错信息如下：

2、使用duplicate target 进行恢复备库

duplicate target database for standby nofilenamecheck dorecover;

Starting Duplicate Db at 05-JUN-17
release channel c1;
release channel c2;
using target database control file instead of recovery catalog
allocated channel: ORA_AUX_DISK_1
channel ORA_AUX_DISK_1: SID=4708 device type=DISK

contents of Memory Script:
{
   set until scn  14430447592;
   restore clone standby controlfile;
}
executing Memory Script

executing command: SET until clause

Starting restore at 05-JUN-17
using channel ORA_AUX_DISK_1

channel ORA_AUX_DISK_1: starting datafile backup set restore
channel ORA_AUX_DISK_1: restoring control file
channel ORA_AUX_DISK_1: reading from backup piece /oracle/backup/data/controlfiles/c-3391761643-20170605-00
channel ORA_AUX_DISK_1: ORA-19870: error while restoring backup piece /oracle/backup/data/controlfiles/c-3391761643-20170605-00
ORA-19505: failed to identify file "/oracle/backup/data/controlfiles/c-3391761643-20170605-00"
ORA-27037: unable to obtain file status
Linux-x86_64 Error: 2: No such file or directory
Additional information: 3

这里恢复失败，google了下，没有找到合适的办法，咋办呢？需要换种思路去恢复了，duplicate此路不通了。

3、尝试使用最原始的rman备份直接restore、recover的方式

copy控制文件、备份文件，备份文件已经有了，所以不需要再次生成，但是控制文件需要再次生成一下，于是在主库上生成最新的备份的控制文件：

RMAN> backup current controlfile for standby format '/home/oracle/ctlfile4.bak';

Starting backup at 05-JUN-17
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=948 device type=DISK
channel ORA_DISK_1: starting full datafile backup set
channel ORA_DISK_1: specifying datafile(s) in backup set
including standby control file in backup set
channel ORA_DISK_1: starting piece 1 at 05-JUN-17
channel ORA_DISK_1: finished piece 1 at 05-JUN-17
piece handle=/home/oracle/ctlfile4.bak tag=TAG20170605T223329 comment=NONE
channel ORA_DISK_1: backup set complete, elapsed time: 00:00:01
Finished backup at 05-JUN-17

Starting Control File and SPFILE Autobackup at 05-JUN-17
piece handle=/oracle/backup/data/controlfiles/c-3391761643-20170605-02 comment=NONE
Finished Control File and SPFILE Autobackup at 05-JUN-17

RMAN>

scp将控制文件和备份文件copy到备库上去

scp -r 2017-06-05 101.251.31.131:/oracle/
scp /home/oracle/ctlfile4.bak 101.251.31.131:/home/oracle/

接下来基本全在备库上进行操作，进行restore standby controlfile恢复控制文件

RMAN> restore standby controlfile from '/home/oracle/ctlfile4.bak';

Starting restore at 05-JUN-17
using target database control file instead of recovery catalog
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=4708 device type=DISK

channel ORA_DISK_1: restoring control file
channel ORA_DISK_1: restore complete, elapsed time: 00:00:01
output file name=/oracle/app/oracle/oradata/powerdes/control01.ctl
output file name=/oracle/app/oracle/fast_recovery_area/powerdes/control02.ctl
Finished restore at 05-JUN-17

RMAN>

启动到mount状态

RMAN> alter database mount;

database mounted
released channel: ORA_DISK_1

RMAN

注册备份集合

RMAN> catalog start with '/oracle/2017-06-05';

Starting implicit crosscheck backup at 05-JUN-17
allocated channel: ORA_DISK_1
channel ORA_DISK_1: SID=4709 device type=DISK

Finished implicit crosscheck backup at 05-JUN-17

4、开始检查主库备库数据一致性

查看归档日志应用情况：

SQL> select sequence#,applied from v$archived_log order by sequence# asc;

     20400 NO

查看后台alert日志，正在进行应用

至此，利用rman备份直接restore、recover的方式恢复了dataguard的standby库。

仔细思考下，这个问题以前一直没有遇到过，磁盘满了后，按照道理来说，清理磁盘后，可以直接恢复得，但是却不能恢复，原因猜测在于启用了实时应用归档日志导致。这样就导致了重新再次传输加载的时候，混乱了。去查看以前的dataguard搭建记录 http://blog.csdn.net/mchdba/article/details/71036947 ，发现有类似的操作记录：

（2）添加current logfile参数，使得应用当前正在读写，还没有完成归档的日志

SQL> alter database recover managedstandby database using current logfile disconnect from session;
