4、这个问题在MOS文章:12.2 DataPump Export (EXPDP) Using a Lower Export Client Fails Due To ORA-39373 (Doc ID 2369249.1)中也有说明(In 12.2 Oracle database, the maximum length of identifiers is increased to 128 bytes for most identifiers, up from 30 bytes in previous releases.)。MOS中的解决方案是对超过30个字符的数据对象进行重命名,然后重新导出。
