如何处理 Ora-600 4193 错误

发布时间:2019-09-13 20:05:55 编辑:笔名

在解决2662错误之后,经常会出现Ora-00600 4193错误,经常可以在alert文件中看到的错误号类似:

Fri Dec 16 22:37:27 2005

Errors in file /opt/oracle/admin/conner/bdump/conner_smon_22817.trc:

ORA-00604: error occurred at recursive SQL level 1

ORA-00607: Internal error occurred while making a change to a data block

ORA-00600: internal error code, arguments: [4193], [1171], [1187], [], [], [], [], []

Fri Dec 16 23:28:40 2005

Errors in file /opt/oracle/admin/conner/bdump/conner_smon_22817.trc:

ORA-00600: internal error code, arguments: [4193], [1171], [1187], [], [], [], [], []

4193错误通常是因为恢复时redo与undo不一致所导致。

Oracle的解释如下:

While backing out an undo record (i.e. at the time of rollback) we found a transaction id mis-match indicating either a corruption in the rollback segment or corruption in an object which the rollback segment is trying to apply undo records on.

This would indicate a corrupted rollback segment.

检查具体的Trace文件,可以发现类似如下错误:

*** 2005-12-16 20:54:53.496

ksedmp: internal or fatal error

ORA-00600: internal error code, arguments: [4193], [1171], [1187], [], [], [], [], []

Current SQL statement for this session:

UPDATE SMON_SCN_TIME SET SCN_WRP=:1, SCN_BAS=:2, TIME_MP=:3, TIME_DP=:4

WHERE TIME_MP = :5 AND THREAD = :6 AND ROWNUM <= 1

由于是UNDO存在不一致,可以通过重建UNDO表空间来解决:

SQL> create undo tablespace undotbs2

2 datafile '/opt/oracle/oradata/conner/undotbs2.dbf' size 10m;

Tablespace created.

SQL> alter system set undo_tablespace=undotbs2 scope=both;

System altered.

SQL> shutdown immediate;

Database closed.

Database dismounted.

ORACLE instance shut down.

SQL> startup

ORACLE instance started.

undo_retention integer 10800

undo_suppress_errors boolean FALSE

undo_tablespace string UNDOTBS2

Tablespace dropped.

至此,Ora-600 4193错误不再出现。

从alert文件中,可以看到自动控制文件备份生效:

Sun Dec 18 22:37:59 2005

Sun Dec 18 22:37:59 2005
