从oracle数据库中使用expdp导出数据时，报以上错误
解决方法之一：添加以下权限
grant EXECUTE ON SYS.DBMS_EXPORT_EXTENSION to public;
grant EXECUTE ON SYS.DBMS_JOB to public;
grant EXECUTE ON SYS.DBMS_RANDOM to public;
grant EXECUTE ON DBMS_SQL to public;
导出数据库可用语句：
exp ppniedb/ppniedb@wisg file=/home/oracle/upgrade_bak/ppniedb.dmp log=/home/oracle/upgrade_bak/expppniedb.log direct=y compress=n rows=y
