I'm troubleshooting an Oracle instance that won't startup due to ORA-15041. The trc file shows this error:

Failed to create file '+FRA_DATA' (file not accessible?)
ORA-19816: WARNING: Files may exist in db_recovery_file_dest that are not known to database.
ORA-17502: ksfdcre:4 Failed to create file +FRA_DATA
ORA-15041: diskgroup "FRA_DATA" space exhausted
WARNING: A file of type ARCHIVED LOG may exist in
db_recovery_file_dest that is not known to the database.
Use the RMAN command CATALOG RECOVERY AREA to re-catalog
any such files. If files cannot be cataloged, then manually
delete them using OS command. This is most likely the
result of a crash during file creation.

Is there a way to manage this with no connection to the database? So far all the solutions I have encountered from research requires a database connection, however I cannot even get the instance up.

Very new to database troubleshooting (actually a web developer), just tasked to troubleshoot this as our DBA left. Any help would be very much appreciated.


  • Do you know your way around ASM?

  • Sadly,no. Heavily relying on google for this.

  • Do you have enough space on the disk? ORA-15041: diskgroup "FRA_DATA" space exhausted

  • I just freed up 20GB of physical space. Initially physical space was all used up when I first had a look at this. I imagine 20GB should be enough?

  • Did you get any other messages after freeing up disk space and starting the instance?

ORA-15041: diskgroup space exhausted

Cause: At least one disk in the diskgroup is out of space.

Action: If all disks are evenly balanced, add more disks to the diskgroup.

According to the log provided in the question, i found that it was unable to complete the archiving operation as the asm diskgroup '+FRA_DATA' is full. The DML operation on large table might have caused this error. You can check if there are extra files - including orphaned archivelogs - that may be in the FRA_DATA.

RMAN>crosscheck archivelog all;

If there is no more space available in FRA_DATA then add disks to diskgroup using ASMCA or ASMCMD utilities.
After adding disks to the diskgroup also check the value of db_recovery_file_dest_size initialization parameter.
The error 15041 possibly relates to the disks in that particular diskgroup. This can happen if the Diskgroup contains disks of unequal sizes.

    since the DG in question appears to be where the FRA is located, you need to consider whether or not regular rman backups are being taken of the database AND the archivelogs -- with rman deleting the archivelogs after they've been backed up. If this isn't being done, you'll quickly consume any space that you add to the DG.
