ORA-39097: Data Pump job encountered unexpected error -56935

参考mos文档：

DataPump Import Fails With Errors ORA-39097 ORA-39065 ORA-56935 / ORA-56938 (Doc ID 1307959.1)

处理如下
ALTER SESSION SET EVENTS '30090 TRACE NAME CONTEXT FOREVER, LEVEL 32';
exec DBMS_DST.UNLOAD_SECONDARY;
查询 DST_UPGRADE_STATE 值
SELECT PROPERTY_NAME, SUBSTR(PROPERTY_VALUE, 1, 30) VALUE
  FROM DATABASE_PROPERTIES
 WHERE PROPERTY_NAME LIKE 'DST_%'
 ORDER BY PROPERTY_NAME;

处理后重新导入，导入正常
