解决方案
SYS@cams>select GROUP#,STATUS from v$log; GROUP# STATUS ---------- ---------------- 1 CLEARING 3 CLEARING 2 CLEARING_CURRENT SYS@cams>alter database clear logfile group 1; Database altered. SYS@cams>alter database clear logfile group 2; Database altered. SYS@cams>alter database clear logfile group 3; Database altered. SYS@cams>select GROUP#,STATUS from v$log; GROUP# STATUS ---------- ---------------- 1 UNUSED 3 UNUSED 2 CURRENT
RMAN> alter database open resetlogs; database opened
如果使用clear logfile的方案不好使,可采用如下方案:
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;
