本文主要向大家介绍了Oracle数据库之ORA-600 kdsgrp1错误解决案例，通过具体的内容向大家展现，希望对大家学习Oracle数据库有所帮助。

当日早上某数据库发现ORA-600错误
Thu Feb 14 09:00:32 2019
Errors in file /u01/app/oracle/diag/rdbms/xxxxdb/xxxxdb/trace/xxxxdb_ora_90063.trc  (incident=880729):
ORA-00600: internal error code, arguments: [kdsgrp1], [], [], [], [], [], [], [], [], [], [], []
Incident details in: /u01/app/oracle/diag/rdbms/xxxxdb/xxxxdb/incident/incdir_880729/xxxxdb_ora_90063_i880729.trc
Use ADRCI or Support Workbench to package the incident.
See Note 411.1 at My Oracle Support for error and packaging details.

我们可以根据抛出600的trc文件中的file#来定位是否存在有物理的坏块。

• kdsgrp1-1: *****
  row 0x031f8070.6 continuation at
  0x031f8070.6 file# 12 block# 2064496 slot 6 not found

验证是否真的坏块

SQL> select owner,segment_name,segment_type from dba_extents where file_id=12 and block_id<=2064496 and (block_id+blocks)>=2064496;

OWNER                          SEGMENT_NAME                                                                      SEGMENT_TYPE

xxx                        T_TE_xxxx_POS_1_0000                                                         TABLE

SQL> select count(*) from xxxx.T_TE_xxxx_POS_1_0000;

COUNT(*)

7171851

SQL>  select name from v$datafile where file#=12;

我们看见Marked Corrupt为0没有坏块，判定是内存中出现坏块导致，如果内存中出现了坏块，没有被老化，可以刷新data buffer来解决。
