ORA-600[6749] 发生在 SYSMAN.MGMT_METRICS_RAW表
数据库alert日志长时间出现ORA-00600[6749]错误
日志报错如下

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;
