oracle报错ORA-39083，ORA-31625，ORA-01031

在使用impdp还原oracle数据库时报错如下：

Processing object type SCHEMA_EXPORT/SYSTEM_GRANT

ORA-39083: Object type SYSTEM_GRANT failed to create with error:

ORA-31625: Schema SYSTEM is needed to import this object, but is unaccessible

ORA-01031: insufficient privileges

创建完成用户后通过如下语句赋权：

grant resource,connect,create view to 你的用户名称;

grant read,write on directory ecology to 你的用户名称;

grant connect,resource,dba to 你的用户名称;
