Oracle HowTo: How to deal with Ora-600 4193 error

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], [], [], [], [], []

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], [], [], [], [], []
