把Oracle归档日志从带库提取到数据库服务器
----------------------------
数据库的所在系统为AIX5.3，数据库的备份通过Tivoli Storage Manage(简称TSM)软件把数据库数据、归档日志备份到带库中。 昆鹏数据恢复

在备份完归档日志到带库后，即删除数据库数据库中的归档日志。现在需要查询数据库中某表的数据具体是哪些用户进行操作的，需要用
到数据库的归档日志。
从带库中把归档日志提取到数据库中的某个位置上。
1、远程登陆或本地登陆数据库服务器系统：
进入rman的命令界面：
LHXXDBS01:oraoms> rman target/
RMAN>list backup;
54ne.com
(这命令把所有的备份都列出来)
如果只提取恢复归档日志，用下面命令即可，然后记住那天归档日志的sequence 号：
RMAN>list backupset of archivelog all; (这命令把所有的归档日志列出来)

RMAN> exit
2、选择存放归档日志的位置，然后执行命令：
RUN
{
SET ARCHIVELOG DESTINATION TO '新位置';
RESTORE ARCHIVELOG SEQUENCE XXXX;
}
注意：如果不用"SET ARCHIVELOG DESTINATION TO '新位置';"该语句，归档日志会在数据库的默认的归档日志目录。
命令如下：
Recovery Manager complete.
LHXXDBS01:oraoms> pwd
/oracle/oms/oradata/temp
LHXXDBS01:oraoms> rman target/

3> restore archivelog sequence 3442;
4> }
executing command: SET ARCHIVELOG DESTINATION

Finished restore at 21-OCT-08
现在已经把sequence号为3442的归档日志转存到/oracle/oms/oradata/temp目录下。
如果需要提取几天的归档日志出来，归档日志比较大、比较多的话，则需要花费很多时间。
