如果使用clear logfile的方案不好使,可采用如下方案:
1 2 3 4 5 6 7 8 9 10 11 12 13 | Recreate the controflile with the RESETLOGS option.
1) Get the controlfile trace from below command :
SQL> ALTER DATABASE BACKUP CONTROLFILE TO TRACE AS '/tmp/control.sql' resetlogs ;
2) Modify the CREATE CONTROLFILE script /tmp/control.sql and ensure that all directories for the online redo logs exist and Oracle has permission to write to it
3) Create the controlfile in NOMOUNT state :
SQL> STARTUP FORCE NOMOUNT
SQL> @/tmp/control.sql
controlfile created
4) Run a fake recovery :
SQL> RECOVER DATABASE USING BACKUP CONTROLFILE UNTIL CANCEL ;
Type <CANCEL> when prompted
5) Open with RESETLOGS option:
SQL> ALTER DATABASE OPEN RESETLOGS;
