ORA-08102之表与索引键值不一致导致带约束关系表不能创建的模拟与解决
**********参考老白、note77587.1 edit by sky on 20111023 qq654268465**********
##############################################################################################
********************************************************************************************
模拟的方法是通过修改CON$表中与其索引相关的键值字段CON#，
具体修改的是NAME=_NEXT_CONSTRAINTT对应的CON#，根据CON$表记录生成过程可知修改是正好是最大键值
首先得到con$表中NAME=_NEXT_CONSTRAINTT这条记录所在块的dump

分析10046 trace
根据错误号8102找trace中sqlid关键字，再根据此查询得到如下结果
可以看到NAME=_NEXT_CONSTRAINT对应的CON#之前值为14218，在更新为14219时发现表中的键值与
索引中的键值不一致从而出错，既然不一致，
那么下一步就根据错误发生时的对象(索引信息)dump出错时的索引块看索引的键值是否有明显错误

******************************************************************************************
从上面10046的trace可以知道表中NAME=_NEXT_CONSTRAINT对应的当前键值为14218
对比索引叶节点块的dump的trace可以知道，对应当前索引键值是14219
此时可以修改表中对应键值为14219，也可以修改索引键值为14218
(对应索引键值的上一个值为142117，中间隔一个，故可以这样做，否则只能修改表对应的键值)
下面的过程采用修改索引键值的方法

###############################################################################
ORA-08102通常是由于表与索引出现不一致导致，通过有三种情况
1.如果损坏为索引，则删除索引并重建索引
------但对于index的obj#小于56的情况，由于是核心的bootstrap$对象，
index是在DB启动时由DB自动创建，此种情况下通过设置event 38003或migrate
都不能解决，但obj#>56的则可以
2.如果损坏为块级别，则采用坏块的处理方法
3.如果损坏的为表的记录级别的则采用bbed或其它工具
---------两边不一致改表和索引都能达到目的，只要一致即可，
但有一个原则就是索引键值始终要保证按顺序递增
