ORA-01194: file 1 needs more recovery to be consistent

1 min read
SQL> alter database open resetlogs;
alter database open resetlogs
ERROR at line 1:
ORA-01194: file 1 needs more recovery to be consistent
ORA-01110: data file 1: ‘/u01/app/oracle/oradata/prod/system01.dbf'

Suppose we are facing this issue while opening the database with resetlogs option.

We have to check how many files have been recovered. We can check with the following command:-

select min(change#),max(change#) from v$recover_file;

————              ————
7533853         7533853

If the files are recovered fully then. We have to go to pfile and add a new line,


After editing the pfile and saving it we have to restart the DB with the pfile.

Shutdown Database
