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，对应数据文件目录环境完全一致
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;

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

此时需要删除redo日志文件，结果在sqlplus里面删除redo日志文件，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日志文件这样简单方便得多。

Database altered.

删除redo03.log后，recover
