INTERVAL类型分区表不支持EXP导出

11G引入了INTERVAL分区，但是INTERVAL分区却不支持EXP导出，只支持DATA PUMP的导出。

EXP-00113: Feature New Composite Partitioning Method is unsupported. Table SCOTT.T could not be exported
Export terminated successfully with warnings.

可以看到一旦表设置为INTERVAL分区，采用EXP就不能导出了。

SQL> ! oerr exp 113
00113, 00000, "Feature %s is unsupported. %s %s.%s could not be exported"
// *Cause:  Export does not contain the required support for this feature.
// *Action: Use Oracle Data Pump Utility

看来ORACLE也在逐步废弃EXP导出工具了。
