今天使用impdp实施数据导入时遭遇ORA-31631、ORA-39122报错，如下所示：

ORA-31631: privileges are required
ORA-39122: Unprivileged users may not perform REMAP_SCHEMA remappings.
C:\Documents and Settings\hoegh>

从报错提示信息来看，是权限不足造成的。通过查阅文档得知，当执行impdp操作指定remap_schema参数时，需要具备imp_full_database权限。接下来，我们给hoegh用户赋予imp_full_database权限。

SQL>

SQL> grant imp_full_database to hoegh;

Grant succeeded.

授权成功后，再次执行impdp语句，成功。
