ORA-20011 ORA-29913 and ORA-29400 with Associated KUP-XXXXX Errors from DBMS_STATS.GATHER_STATS_JOB(

Posted 2020-08-20 guilingyang

首先在alert log裡面頻繁的看見如下錯誤：

DBMS_STATS: GATHER_STATS_JOB encountered errors.  Check the trace file. Errors in file /oracle/diag/rdbms/phalr/phalr/trace/phalr_j001_5306.trc: ORA-20011: Approximate NDV failed: ORA-29913: error in executing ODCIEXTTABLEOPEN callout KUP-11024: This external table can only be accessed from within a Data Pump job.

不太看得明白，去MOS搜索到一篇文章

ORA-20011 ORA-29913 and ORA-29400 with Associated KUP-XXXXX Errors from DBMS_STATS.GATHER_STATS_JOB (Doc ID 1274653.1)

该文详尽的描述了解决这个异常，我们在datadump导入导出的都是，都会产生一个类似SYS_EXPORT_TABLE_02的表，如果是正常导完oracle会自动清除这个表，那么如果导入导出的时候中断，那么这个表就不会被清除，这个ora错误的引起就与这个有关系。

Temporary Datapump external tables have not been cleaned up properly. The dictionary information should have been dropped when the DataPump jobs completed.

解决方案就是清除Datapump遗留的临时外部表，下面是详细过程
