python使用Cx_Oracle 连接数据库报错

做了个工具打包的EXE， Oracle客户端的DLL都打包进去了， 所有测试正常，交付客户后客户连接数据库时报一下错误。
Connection Failed: ORA-00604: error occurred at recursive SQL level 1
ORA-20000: …˯܊＊＊＊＊许可された接続方法以外では利用できません…˯܊＊＊＊！EORA-06512: at line 25

另之前成功连接过，但是导出数据时有时也会报这个错：
ORA-03113: end-of-file on communication channel
。

求问大神这是什么原因？
