RMAN异机还原遭遇ORA-19698错误案例

2024-07-04 17:16:57   230人阅读

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;

Starting recover at 14-MAY-14

using channel ORA_DISK_1

RMAN-00571: ===========================================================

RMAN-00571: ===========================================================

RMAN-03002: failure of recover command at 05/14/2014 10:15:30

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，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。

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

SQL> alter database drop logfile group 3;
 
alter database drop logfile group 3

ERROR at line 1:

删除redo03.log后，recover database成功
