1，在执行expdp的时候，报错ORA-31637

在plsq界面，启动sql导入的方式是可行的，但是速度非常慢，同事以及客户着急这部分数据导入，尝试去服务器上面执行expdp导出，但是报错ora-31626了

[oracle@orct~]$ time expdp 'dw/"pw1817"'@PD1 DIRECTORY=DIR_DUMP_01 DUMPFILE=dw_20170622.dmp tables=ads_pd_zjsals_proj_m,ads_pd_sjyswc_proj_m LOGFILE=zhanghaoxiang.log;

2，赋予DBA权限，尽快导出数据

google了下，查到是权限不足的问题，尝试赋予dba权限，试试看
[oracle@orct~]$ rlwrap sqlplus / as sysdba

3，收回DBA权限

[oracle@orct~]$ rlwrap sqlplus / as sysdba

Revoke succeeded.

4，比较完善的办法

查看官方文档http://docs.oracle.com/cd/E11882_01/server.112/e22490/dp_import.htm

里面有关于expdp的权限问题描述，需要DATAPUMP_EXP_FULL_DATABASE、DATAPUMP_IMP_FULL_DATABASE操作权限，一会可以采取赋予以下权限给普通用户，这样普通用户也可以通过expdp/impdp来导出导入数据了，如下所示：

sql> grant DATAPUMP_EXP_FULL_DATABASE  to dw;

Grant succeeded.

sql> 
sql> grant DATAPUMP_IMP_FULL_DATABASE   to dw;

Grant succeeded.
