退出sqlplus，并再次进入sqlplus（为的是能生成在一个新的trc中）

在udump下获得trc文件：该文件有1600多行，因此不全部列出。以“Leaf block dump”为关键字搜索该文件：

下面来分析16进制的rowid：
01 00 14 26 01 66 --->这是16进制
00000001 00000000 00010100 00100110 00000001 01100110 --->这是换算成2进制后的（对01用calc.exe换算，对00用calc.exe换算，对14用calc.exe换算，等等）
00000001 00 ---->文件号 ：4 ------------------------------------->4是换算成10进制后的值（使用calc.exe换算）
000000 00010100 00100110 ----->块号 ：5158 ------------------------->5158是换算成10进制后的值（使用calc.exe换算）
00000001 01100110 ---->行号：358 ------------->358是是换算成10进制后的值（使用calc.exe换算）
前十位表示文件号
中间22位表示块号
最后16位表示行号
下面来分析2个索引值：
col 0; len 5; (5): 31 30 36 31 31 -------------->这是索引列的值
col 1; len 7; (7): 78 73 04 08 0f 3c 19--------->这是索引列的值
使用函数f_get_from_dump将上述值转换 （该函数来自travel大师：http://www.traveldba.com/wp-content/uploads/scripts/f_get_from_dump.sql）
