Changes

No Specific changes.

Cause

Rebalance operation can be initiated because of disk being added or manual rebalance.

Cause of the crash is observed to be the UNPROTECTED files created in the diskgroup.

Issue is verified in UNPUBLISHED Bug 12319359 - SOL-X64-SC:HIT ASM ORA-00600:[KFDARELOCSET10], [3], [256], [3], [1], [1], [65535]

Solution

The use of UNPROTECTED files is not recommended in production environments.

Creating a file with UNPROTECTED is equivalent to having a diskgroup with external redundancy. Disk failure can cause the copy data to be unavailable and this can lead to the issue.

UNPUBLISHED Bug 12319359 is under investigation by Development with lower priority, considering that usage of UNPROTECTED files is not recommended in production environments.

If the file that is causing the issue is a tempfile, we can drop it first and then start the rebalance to avoid the error.

SQL> select group_number,file_number,blocks,bytes,space,redundancy,striped,REDUNDANCY_LOWERED,MODIFICATION_DATE
from v$asm_file where group_number=1 and file_number=290;

SQL> select * from v$asm_alias where group_number=1 and file_number=290;
-- change the group_number and file_number based on the arguments of the ORA-600 error.

SQL> alter tablespace TEMP drop tempfile <file_name>
