Research And Implementation Of Commercial Bank's Console System For Foreign Card Front-end

With the popularity of credit cards, bank card transactions have increased year afteryear, especially with the upgrading of China's international status and the success of Beijingas the host of the 08's Olympic Games, the influx of foreign domestic cardholders has madethe volume of business of foreign card in China leaps into the trend. To enhance theacceptance environment of the foreign cardholder in the country and improve the success rateof transactions, most banks develop their foreign card acquiring systems rapidly to meet theneeds from market and customer; at the same time, to improve their foreign card businessprocessing system has become the most necessary and urgent work.With the rapid development of the global computerized financial services, thetransaction model of the banks is integrating continuously. In the integration process, thechange of original computerized trading system has an impact on the model and process ofthe bank business; and with the development of data processing to the large centralizeddirection, the front-end system of bank has become the center and access window in the entireautomation system in the bank. The centralized data center of each commercial bank onlyfaces the front-end outside the system and all transactions are received from the front-endsystem. Front-end system is responsible for handling all of the channels access, operationspretreatment, intermediate business processes, routing processing and the access processing ofservices channel, so it is the essential part of the whole bank system.With the increasing of foreign card transactions and platform applications, and theadvancing of data concentration step by step, the number of servers used for applicationsystem and open platform is increasing fiercely and the routine maintenance work of an openplatform system has become increasingly complex. With the Olympic Games and World Expoheld in China, foreign card transactions will also significantly increase, leading to that thedaily maintaining workload of the maintenance personnel in bank data center is increasing,including the day cut, volume maintenance, parameter setting, etc., and the workload of background operators is increasing because of the data exchanging and processing with theforeign card organizations every day. Consequently, a kind of simple and secure integratedconsole system needs to be developed, to make the operator call the online in the front-endserver through the console system in PC every day and to facilitate the batch programming,the completion of a liquidation files of all card, the loading and generating of a liquidationfiles of host, the handling and checking of exception transactions. Operations personnel don'thave to control the daemon directly, so to simplify the steps, add the operational safety,further improve the operational automation, reduce the strength of the operator to runoperations and reduce the risk of running operations.Now, with the continuously increasing of bank card, bank card transaction types andrange, the number of servers used for application system and open platform is increasingfiercely, and the routine maintenance work of front-end system has become increasinglycomplex.This paper gives the detailed description and in-depth discussion on the structureoptimization goals and the stepped program strategy of commercial banks foreign cardfront-end system, aims to the requirements for increasingly stringent data processing,proposes a kind of design programs and volume access principle of automated batch controlsystem, which for the conditions qualified for the functions of batch implementationCategory of the Development platform, the fundamental idea is that to achieve businessrequirements by online transactions as much as possible and maximally streamline the bulkof the load in defining the principles of batch operation. Some aspects are included asfollows.1. The principle of mass access:The achievement of function does not satisfy the real-time requirements and thereturn of results has no response time limit.The management of a large number of data or logic is complex, and because of thetime constraints of online transaction response, the possibility to achieve onlinetransactions is precluded.if the required functions are implemented through on-line transactions, onlineprogram lock waiting or deadlock may be caused. The necessary system operations to run the business volume are batch operations.2. The principle of non-manual:Automatically obtain and calculate the required input parameters of batch programby reading the parameter list.To determine batch processing work by the work calendar, whose managementfunctions are advised to implement in their own specific applications and providemaintenance interface to the business operations, if the setting of work calendarrequires the periodic adjusting of the operational staff.3. The principle of breakpoint adjourned and breakpoints redoThe functions of batch program redo and breakpoints adjourned are considered onthe structure and processes when batch system is designed.If the conditions of breakpoints adjourned are satisfied (generally insert and updateoperations have breakpoint adjourned conditions and statistics and queryoperations do not) and the running time of batch procedures is more than 30minutes, breakpoints adjourned is needed, it is ok for others to support breakpointsredo.For the table without unique identifier and cannot be sorted, can be treatedsimilarly to increase the state flag to achieve breakpoints adjourned.4. The principle of fault-tolerant:The fault-tolerant mechanisms of batch program are needed for the illegal orquestionable logic situations, and in the process for non-disruptive mistakes, errormessage will be registered to the volume error message in the table, the errorrecord is skipped, batch processing is continued, and the follow-up process isbased on an error registration book by the relevant departments.5. The principle of monitoring the progress of operation:Progress display is divided into two levels: call monitoring of batch program leveland control within the code of batch program.If the expected running time of running program in single batch is more than 30minutes, the call monitoring of batch program level is increased.Monitoring is running within the code of batch program, regularly output the number of records both processed and the total to the console, recommendssubmitting the number once every 5 minutes, and the submitting interval can beadjusted by parameter configuration method.The design concept is proposed with the consideration of many aspects one of which isthe insecurity of batch work and program running. In addition, the automatic batchprocessing platform of foreign card front-end bank is developed on the basis of the existingsystem of bank. For the functional design, the platform is divided into four parts: fileoperations modules, the system parameter configuration module, user management moduleand routing management module. File operations module consists mainly of five dailyliquidation processes of foreign card organizations and host, and this paper mainly describesthree steps of the receiving, loading and sending of the foreign card organization files.System parameter configuration module consists mainly of online organizationconfiguration, database connection configuration, foreign card server configuration, textmessage etc. User management module contains operator access control, production-lineinquiry etc. Routing management module contains the starting routing.
