rman备份恢复时归档位置说明

Posted 2020-11-28

一、说明

1、参数 log_archive_format 和 log_archive_dest_n 决定了rman恢复时获取归档的路径和名字。
2、使用方法
从归档备份中恢复归档到新的位置
run{
set archivelog destination to ‘/oracle/test/archivelog/‘;
restore archivelog from sequence 1;
}
调用新位置的归档进行数据库恢复
run
{
set archivelog destination to ‘/oracle/test/archivelog/‘;
restore database;
recover database;
}

二、例子

1、从备份恢复归档到指定位置
RMAN> run{
2> set archivelog destination to ‘/oracle/test/archivelog/‘;
3> restore archivelog from sequence 1;
4> }

executing command: SET ARCHIVELOG DESTINATION

2、调用指定位置的归档进行recover操作
RMAN> run

3> set archivelog destination to ‘/oracle/test/archivelog/‘;
4> restore database;
5> recover database;
6> }

executing command: SET ARCHIVELOG DESTINATION
using target database control file instead of recovery catalog
