前几天培训班中有学生问到,对于cluster table如果去实现手工提交事务,来屏蔽一些错误.他在自己的
环境中遇到了ora-00600 4000错误,涉及的对象即为cluster table,下面我这里简单模拟了一下。供参考!

大家可以看到，这跟普通的data block的dump内容是有所差别的，因为这里涉及到cluster table。
下面来模拟下手工提交cluster table的事务。

这里我们可以看到对于这个未提交的事务XID为：3.17.1212? 前面我们已经知道
测试表中的数据分布在3个block中，这里我模拟的情况是删除第3条数据，且不提交，通过bbed来实现手工
提交这个未提交事务，注意：第3条数据是在第3个block中，即174 block。
+++++首先修改表的itl等信息

我们可以看到，无论怎么修改，这个block通过bbed进行检测都报错，这里不是因为修改的不对,而是因为
还需要修改cluster 上的Index信息。通过treedump 我们可以确认index block为file 6 block 187.

到这里，我们完成了Index Block的修改，最后我们再来校验一下前面的data block，你会发现已经ok了，如下：
BBED> set file 2 block 174
FILE#?????????? 2
BLOCK#????????? 174
BBED> verify
DBVERIFY – Verification starting
FILE = /oracle/oradata/roger/sysaux01.dbf
BLOCK = 174
DBVERIFY – Verification complete
Total Blocks Examined???????? : 1
Total Blocks Processed (Data) : 0
Total Blocks Failing?? (Data) : 0
Total Blocks Processed (Index): 0
Total Blocks Failing?? (Index): 0
Total Blocks Empty??????????? : 1
Total Blocks Marked Corrupt?? : 0
Total Blocks Influx?????????? : 0
