楼主

实验环境：

操作系统：Oracle Linux Server release 5.7 64 bit

数据库版本：Oracle Database 10g Release 10.2.0.4.0 - 64bit Production

案例说明：

为了测试、验证备份的有效性，需要将服务器A上的数据库的备份集还原到服务器B上，服务器B上已经创建了相同名称的ORACLE_SID和DB

Name
Step 1： startup nomount
Step 2: restore spfile
Step 3： restore controlfile
Step 4: startup mount;
Step 5: restore database
Step 6: recover database

由于在没有在RMAN还原时忘记设置 DBID，结果在执行recover database时报ORA-19698:

/u01/oradata/SCM2/redo01.log is from different database: id=4146921064,
db_name=SCM2

RMAN> recover database;

using channel ORA_DISK_1
RMAN-00571:

ORA-19698: /u01/oradata/SCM2/redo01.log is from different
database: id=4146921064, db_name=SCM2

此时需要删除redo日志文件，结果在sqlplus里面删除redo日志文件，结果遇到下面一系列问题。其实可以直接使用rm命令直接删除redo日��文件要简单方便得多。

SQL> alter database drop logfile group 1;
Database altered.
RMAN> recover database;

using channel ORA_DISK_1

different database: id=4146921064, db_name=SCM2

删除redo03.log后，recover database成功
