通過impdp命令將Oracle11g數據庫的dmp文件導入至Oracle10g中時，報出如下錯誤：
[oracle@dbsrv3 ~]$ impdp dhccms/dhccms DIRECTORY=DATA_PUMP_DIR DUMPFILE=DHCCMS.DMP FULL=y; Import: Release 10.2.0.1.0 - 64bit Production on Monday, 26 November, 2018 15:14:12 Copyright (c) 2003, 2005, Oracle.

Connected to: Oracle Database 10g Enterprise Edition Release 10.2.0.1.0 - 64bit Production With the Partitioning, OLAP and Data Mining options ORA-39006: internal error ORA-39213: Metadata processing is not available
錯誤信息：
ORA-39213: Metadata processing is not available
解決辦法：
將需要導入數據的用戶暫時給予dba權限，然后執行impdp導入命令。
執行結束之后再去除dba權限。
