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(dòng)數(shù)據(jù)庫報(bào)錯(cuò)

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(duì)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(dòng)到mount

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

方法一:利用自動(dòng)備份

RMAN> restore  spfile from autobackup;

自動(dòng)備份這里會(huì)報(bào)錯(cuò),因?yàn)槲覀儧]有設(shè)置自動(dòng)備份

方法二:利用手動(dòng)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';
