实验准备
OGG (DBID=3068169019)
spfile：/u01/app/oracle/fast_recovery_area/OGG/backupset/2018_03_26/o1_mf_ncsnf_TAG20180326T162759_fckd47yp_.bkp
我们分两种情况
1.不知道DBID，知道备份路径
2.知道DBID
（1）.模拟删除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）.启动数据库报错
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'
针对第一种情况
1.不知道DBID，知道备份路径
[oracle@ogg-80 ~]$ rman target /
RMAN> startup nomount; ------启动到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'

针对第二种情况
2.知道DBID

RMAN> startup nomount;

方法一：利用自动备份
RMAN> restore spfile from autobackup;
自动备份这里会报错，因为我们没有设置自动备份
方法二：利用手动备份
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';
