夏日肇始，樱桃上市，是采摘的好时节。
周日，前同事朋友们一起到京西的白家疃进行樱桃采摘，这是盖小咪非常开心的一天。感谢大家伙！
开车到白家疃，有很多可以采摘的园子，找老乡谈好价钱（30元/斤，吃不限，每人至少采摘两斤）大家就开始进院采摘。
其实最快乐的是整个过程，JJ同学说采摘会上瘾，最后我们一共摘了22斤，超额完成了任务。
看看这红彤彤的樱桃，谁也收不住伸出去的手吧：
墨墨非常开心，四处跑来跑去，不时伸出小手去摘樱桃，事实上他从头天晚上就开始念叨摘樱桃了。
爬在梯子上，墨墨也不害怕：
这是墨墨非常快乐的一天，也是我们大家非常快乐的一天！

Export ORA-00904: "Ifreepool": Invalid Identifier

在使用Oracle 10.2.0.4的客户端来全库Exp Oracle 10.2.0.3的数据库时，会出现如下错误：EXP-00008: ORACLE error 904 encountered这是因为版本不一致导致的，在遇到包含LOB对象的表时触发，这是因为10.2.0.4中，管理LOB对象发生了变化，在字典中引入了一些新的字段，如'IFREEPOOL'.
ORA-00904: "IFREEPOOL": invalid identifier
EXP-00008: ORACLE error 1003 encountered
ORA-01003: no statement parsed
10.2.0.3中不包含相应字段，在EXP时就出现了错误。
在Metalink上的Note：726182.1中，Oracle指出：Client 10.2.0.4.0 is not supported to export from 10.2.0.3.0 database。
也就是说使用10.2.0.4的客户端导出10.2.0.3不被支持，也没有Workaround，我们应当使用匹配的版本来执行导出工作。
相关文档说明摘录如下：
Applies to:
Oracle Server - Enterprise Edition - Version: 10.2.0.3 to 10.2.0.4
This problem can occur on any platform.Symptoms
Export reports ORA-00904 "IFREEPOOL": invalid identifier while using a version 10.2.0.4.0 export client to export from a 10.2.0.3.0 database.
Export Log File
---------------
. . Export der Tabelle CALCULATEDFIELDS
EXP-00008: ORACLE-Fehler 904 aufgetreten
ORA-00904: "IFREEPOOL": invalid identifierCause
This is an expected behaviour.
The version of the Export utility must be equal to the earliest version of the source or target database. Here, the source database is based on release 10.2.0.3.0 and hence the export client has to be a version 10.2.0.3.0.
An export client of a later release cannot be used for the following reasons:
- The export utility is continuously accessing dictionary objects such as SYS.EXU9LOB.
- Starting with release 10.2.0.4.0 we introduced additional columns such as 'IFREEPOOL'. This column is not available in 10.2.0.3.0 and hence the client cannot handle this and ORA-00904/EXP-00008 appears.
Client 10.2.0.4.0 is not supported to export from 10.2.0.3.0 database.
Solution
FIX
The version of the Export utility must be equal to the earliest version of the source or target database.
WORKAROUND
None. - This is an expected behaviour.
