Error in Check DB after RESTORE and RECOVER

Hi Team,

System was partially restored and recovered due hardware failure.

We had 3 file systems that had to be restored and in one of them we has "/oracle/BWP/sapdata8/temp_2/temp.data2" data file.

After the restore and recovery , the system was up.When ran check DB , the get the below error message and when i checked in DB02 , everytime when trying to see the datafile inside PSAPTEMP , there is a short dump with the same error message listed below.

Database error text........: "ORA-01157: cannot identify/lock data file 256 -

see DBWR trace file#ORA-01110: data file 256:


When checked the restore , looks like "oracle/BWP/sapdata8/temp_2/temp.data2'" was not restored.

Kindly help to check how to correct this error. Even my online backup's are failing.

    Hello Priyanka,

    how did you restore your database?

    The temporary files are not included in a backup, because they are not needed for a recovery - that works as designed.

    After the recovery you have to add these files again.

    If you would have used brrecover for restoring/recovering your database the temporary files would be added automatically.

    Check the documentation here:

    Now you have to do this manually like this:

    shell> sqlplus / as sysdba
    SQL> ALTER TABLESPACE PSAPTEMP ADD TEMPFILE '/oracle/BWP/sapdata8/temp_2/temp.data2' REUSE;
