KUP-11024: This external table can only be accessed from within a Data Pump job.

Sat Jun 13 14:08:06 2015

Thread 1 cannot allocate new log, sequence 11157

错误原因：

外部表对应的操作系统上的外部表文件不存在了。但是，数据依然相信操作系统上的外部表文件还存在。

当DBMS_STATS运行，收集这个外部表的统计信息，由于外部表的文件不存在了，所以出现了上述错误。

外部表不存在的情况如下：

1、没有正确的清理datapump的临时外部表(使用datapump将查询结果填充到外部表的情况，http://czmmiao.iteye.com/blog/1268712)。

datapump job结束后，临时外部表应该会被删除掉。

2、外部表文件已经被删除，但是没有清理外部表的定义。

解决办法：

1、DBMS_STATS job 运行时，没有DataPump job运行

2、检查并清理孤儿DataPump jobs。

3、确定外部表属于datapump job

外部表ET$0071FF750001的定义,看着像是datapump创建外部表。datapump导出的dmp文件作为外部表的数据文件。
