NBU6.5 oracle 恢复归档日志是报错，麻烦帮忙分析一下

Question

list backup可以看到有做归档日志的备份，但在 resotre时却报找不到文件。现在如恢复nbu备份过的所有archivelog日志？

RMAN> run {
2> allocate channel t1 type SBT_TAPE;
3> RESTORE ARCHIVELOG ALL;

Answer 1

run {
allocate channel t1 type SBT_TAPE;        
restore archivelog sequence 21 thread 1;
release channel t1;
}

这样就可以恢复。

Answer 5

从list backup结果看你的备份集备份的归档只有18,19,20。所以恢复sequence 8-12当然报错了。
如果在sql提示符下恢复，先确保'/u01/app/oracle/flash_recovery_area/ORCL/archivelog/2011_04_19/下面有18-21的归档。
如果归档在别的位置，如/archivelog，应该执行recover from ‘/archivelog' tablespace RMAN_TS.
如果在rman下恢复，直接recover tablespace RMAN_TS就可以。所需归档自动会从备份集恢复到/u01/app/oracle/flash_recovery_area/ORCL/archivelog/2011_04_19/下。
