猜测ORA-600[6749]部分参数

SQL> select  DBMS_UTILITY.data_block_address_file (12596882) "file#",
  2  DBMS_UTILITY.data_block_address_block (12596882) "block#"
  3  from dual;
     file#     block#
---------- ----------
         3      13970

ORA-600[6749][a][b]{c}
这里证明c表示rdba

根据dba查询对象

SQL> select * from dba_extents where 13970 between block_id and block_id + blocks and file_id=3;
OWNER      SEGMENT_NAME                     SEGMENT_TYPE
---------- ------------------------------- -------------------
SYSMAN        SYS_IOT_OVER_10448                 TABLE
SQL> select owner,iot_name from dba_tables where table_name = 'SYS_IOT_OVER_10448';
OWNER                          IOT_NAME
------------------------------ ------------------------------
SYSMAN                         MGMT_METRICS_RAW
SQL>  ANALYZE TABLE SYSMAN.MGMT_METRICS_RAW  VALIDATE STRUCTURE CASCADE;
Table analyzed.

按照常理ORA-00600[6749]错误是因为坏块或者表和索引数据不一致导致,通过ANALYZE可以检查出来.这里显示正常,那可能是其他原因导致,查询MOS果然发现是ORA-600 [6749] Occurring on SYSMAN.MGMT_METRICS_RAW [ID 467439.1]

解决方法

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;

3. Truncate the table:
SQL> truncate table 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;
    回复

  2. select * from dba_extents where 3056 between block_id and block_id + blocks and file_id=3;
    这里的3056是什么，应该是dba吧，是不是写错了，你这案例的dba应该是13970 吧！
