Ora-00600 4193一般来说是undo表空间的问题。

我们来看看一个实例
在trc文件里出现

Fri Dec 16 22:37:27 2005 Errors in file /opt/oracle/admin/orcl/bdump/orcl_smon_22817.trc:ORA-00604: error occurred at recursive SQL level 1ORA-00607: Internal error occurred while making a change to a data blockORA-00600: internal error code, arguments: [4193], [1171], [1187], [], [], [], [], []Fri Dec 16 23:28:40 2005Errors in file /opt/oracle/admin/orcl/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:

引用:

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/orcl/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.

SQL> show parameter undo
NAME TYPE value
------------------------------------
undo_management string AUTO
undo_retention integer 10800
undo_suppress_errors boolean FALSE
undo_tablespace

SQL> drop tablespace undotbs1 including contents and datafiles;

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
drop tablespace undotbs1 including contents and datafiles
