猜测ORA-600[6749]部分参数

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;
