CAUSE
This issue was investigated in Bug 6127434 but not resolved due to lack of information.
Abstract: ORA-600[6749] RAISED BY DELETE COMMAND; NO CORRUPTION IDENTIFIED
SOLUTION
The following workaround may resolve the problem temporarily:
1. Ensure you have a good backup before proceeding.
2. Create a copy of the SYSMAN.MGMT_METRICS_RAW table:
SQL> create table SYSMAN.MGMT_METRICS_RAW_COPY
as select * from SYSMAN.MGMT_METRICS_RAW;
3. Truncate the table:
SQL> truncate table SYSMAN.MGMT_METRICS_RAW;
May need to disable trigger: "sysman.raw_metrics_after_insert" before proceeding. Re-enable after the insert.
4. Re-insert the rows:
SQL> insert into SYSMAN.MGMT_METRICS_RAW
select * from SYSMAN.MGMT_METRICS_RAW_COPY;
SQL> commit;
5. Drop the copy table:
SQL> drop table SYSMAN.MGMT_METRICS_RAW_COPY;

_KDTGSP_RETRIES
Description
A chained row (logical row continued in another row) in a table
can be corrupted where the next row piece (nrid) points to itself.
Data corruption resulting from a lost row piece can occur very
intermittently in blocks experiencing high concurrency in MSSM
tablespaces (dba_tablespaces.segment_space_management=MANUAL).
It is most likely to happen but not limited to tables with a large
number of columns (e.g. more than 255 columns).
Subsequent SQL operations may produce wrong results or different
errors like:
ORA-600 [6749] by DELETE
ORA-8102 by UPDATE (if the table has indexes)
ORA-600 [qertbFetchByRowID]
ORA-1499 by "analyze table validate structure cascade"
(logical corruption between index and table as the table is
returning wrong values for the affected row)
Without the fix of Bug 8720802 tools like DBVERIFY / RMAN / ANALYZE
don't detect this logical corruption.
Corruption Example from a block dump:
Row 3 in Block rdba 0xad858746 :
tab 0, row 3, @0x6e9
tl: 127 fb: --H-F--- lb: 0x0 cc: 33
nrid: 0xad858746.3 --> it points to the same row 3
The fix for this bug does not repair existent corruptions.
Workaround
1. Once the corruption is introduced:
Recreate the table skipping the row:
"Create Table As Select (CTAS) where rowid != "
or similar can be used
eg: export with query clause (where rowid != )
then drop or truncate, import
OR
Install the enhancement in Bug 8720802 and use dbms_repair to
Soft Corrupt the affected block and skip it for DML's
2. To prevent the issue move the table to ASSM tablespace
(dba_tablespaces.segment_space_management=AUTO).
Note: This fix can lead to the problem described in bug 9368502
