将数据写入文件时Web服务出现问题 [英] Problem with web service while writing data into files

问题描述

嗨..

长时间后，我在Code Project中发布了一个问题.我非常分散了这个问题.目前，即使我也无法确定问题出在哪里.

请阅读我的整个主题，以清楚地了解我的问题.

项目:我为印度一家著名的银行开发了一个项目，用于收集偏远地区的贷款金额.每个收款代理都有设备(已启用Linux和GPRS)以收集贷款金额.如果GPRS连接可用(数据量很少(200字节))，则每个设备都会立即将付款收据详细信息发送到服务器.如果gprs不存在，它将存储在内部存储器中，当设备进入GPRS区域时，它将发送总数据(非常高).

Web服务:Web服务将从设备接收数据并将其保存到文件(文件名:mechineid [unique] + datetime)中，然后转储到数据库中，并在同一会话中将确认发送回设备
/>
**它适用于少量数据(当GPRS可用时).但是，当设备向大量数据发送数据时，它也可以正常运行.

问题:现场有1200多个设备，这些设备会定期发送大量数据. 某些设备正在以与数据合并到一个文件相同的几分之一秒发送数据.我正在将此文件写入两个不同的文件夹中，即使这些文件正在混合.我无法追踪到底发生了什么.

这是写入文件的代码

Hi..,

After a long time i am posting a Question in Code Project. I very much distributed with this problem. Presently even i am not in a position to where is the problem is occurring.

Please read my entire thread to understand my problem clearly.

Project : I developed a Project for one of the reputed Bank in India for Collecting the loan amounts in remote locations. Every Collection Agent have Device(Linux, GPRS enabled) to collect the loan amounts. Every device will send the payment receipt details to the server immediately if GPRS connection is available(which is very less data(200 bytes)). If gprs is not there it will store in the internal memory, when the device came into GPRS area it will send total data(which is very high).

Web service : Web service will receive the data from Device and saving into the file(filename: mechineid[unique]+datetime) then dumping into the database, sending back Acknowledgment to the device in same session

** it is working fine for the small amount of data(when GPRS is available). But when device is sending to the huge data it''s also receiving fine.

Problem : There are 1200+ devices in the field, which are send the huge data regularly. some device are sending data at same fraction of second that data is merging into one file. i am writing this files in two different folders even those files are mixing. i am not able to trace what is exactly happening.

Here is the code for writing file

public string Execute_DCR(ref Globals.Globals.CliRequest ObjClient, ref  Globals.Globals.RequesInfo HttpReq, string MechineID, string FileBytes)
       {
           string return_str = "^NACK@";

           string BranchCode = Pick_Brach_Code(MechineID);
           string TempFIlename=ConfigurationManager.AppSettings["isbnPath"] + "\\" + BranchCode + "\\upload\\" + MechineID + "_" + DateTime.Now.ToString("ddMMyyyyHHmmss") + ".dat";

           FileStream Fs = new FileStream(TempFIlename, FileMode.CreateNew, FileAccess.Write);
           BinaryWriter Bw = new BinaryWriter(Fs);
           Bw.Write(Encoding.UTF8.GetBytes(FileBytes));
           Bw.Close();
           Fs.Close();
           DumpToSQL(TempFIlename);

           return_str = "^ACK@";
           HttpReq.Respocestring = return_str;
           ObjClient.Command = return_str;
           return return_str;
       }
