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
ORA-00904: "IFREEPOOL": invalid identifier
EXP-00008: ORACLE error 1003 encountered
ORA-01003: no statement parsed

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'.
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 identifier 

Cause

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.
