ORA-00392: log 5 of thread 1 is being cleared, operation not allowed ORA-00312

Hi,

When you open database with resetlogs option, you can get ” ORA-00392: log 5 of thread 1 is being cleared, operation not allowed” error.

 

When I open Oracle database with resetlogs like following, I got ” ORA-00392: log 5 of thread 1 is being cleared, operation not allowed ” error.

SQL> 
SQL> alter database open resetlogs; 
alter database open resetlogs
*
ERROR at line 1:
ORA-00392: log 5 of thread 1 is being cleared, operation not allowed
ORA-00312: online log 5 thread 1: '/data/DEVECI/redologs/o1_mf_5_g11qrjms_.log'
ORA-00312: online log 5 thread 1: '/data/DEVECI/redologs/o1_mf_5_g11qrjoz_.log'

 

To solve this problem, you can clear related online log group like following.

You should change group number according to your environment.

SQL> alter database clear logfile group 5;

Database altered.

 

Or Sometimes you may need unarchive it, you can execute following script to solve.  You should change group number according to your environment.

SQL> alter database clear unarchived logfile group 1;

Database altered.
