RMAN異機還原遭遇ORA-19698錯誤案例

實驗環境：

              操作系統    ：Oracle Linux Server release 5.7 64 bit

              數據庫版本：Oracle Database 10g Release 10.2.0.4.0 - 64bit Production

案例說明：

為了測試、驗證備份的有效性，需要將服務器A上的數據庫的備份集還原到服務器B上，服務器B上已經創建了相同名稱的ORACLE_SID和DB Name，對應數據文件目錄環境完全一致

Step 1： startup nomount

Step 2：  restore spfile

Step 3： restore controlfile

Step 4：  startup mount;

Step 5：  restore database

Step 6： recover database

由於在沒有在RMAN還原時忘記設置 DBID，結果在執行recover database時報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

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

此時需要刪除redo日志文件，結果在sqlplus里面刪除redo日志文件，遇到下面一系列問題。其實可以直接使用rm命令直接刪除redo日志文件這樣簡單方便得多。

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:

刪除redo03.log后，recover database成功
