rman怎么恢復spfile

rman怎么恢復spfile，相信很多沒有經驗的人對此束手無策，為此本文總結了問題出現的原因和解決方法，通過這篇文章希望你能解決這個問題。

實驗準備

OGG (DBID=3068169019)

spfile：/u01/app/oracle/fast_recovery_area/OGG/backupset/2018_03_26/o1_mf_ncsnf_TAG20180326T162759_fckd47yp_.bkp

我們分兩種情況

1.不知道DBID，知道備份路徑

2.知道DBID

（1）.模擬刪除spfile

[oracle@ogg-80 dbs]$ cd /u01/app/oracle/product/11.2.0/dbhome_1/dbs

[oracle@ogg-80 dbs]$ mv spfileogg.ora spfileogg.ora.bak

（2）.啟動數據庫報錯

SYS@ogg> startup force;

ORA-01078: failure in processing system parameters

LRM-00109: could not open parameter file '/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initogg.ora'

針對第一種情況

1.不知道DBID，知道備份路徑

[oracle@ogg-80 ~]$ rman target /

RMAN> startup nomount;  ------啟動到mount

startup failed: ORA-01078: failure in processing system parameters

LRM-00109: could not open parameter file '/u01/app/oracle/product/11.2.0/dbhome_1/dbs/initogg.ora'

starting Oracle instance without parameter file for retrieval of spfile

針對第二種情況

2.知道DBID

[oracle@ogg-80 ~]$ rman target /

RMAN> set dbid=3068169019

executing command: SET DBID

RMAN> startup nomount;

方法一：利用自動備份

RMAN> restore  spfile from autobackup;

自動備份這里會報錯，因為我們沒有設置自動備份

方法二：利用手動備份

RMAN> restore spfile to '/u01/app/oracle/product/11.2.0/dbhome_1/dbs/spfileogg.ora' from '/u01/app/oracle/fast_recovery_area/OGG/backupset/2018_03_26/o1_mf_ncsnf_TAG20180326T162759_fckd47yp_.bkp';
