Design And Implementation Of Simulation Debit Card System Based On CICS Middleware

As of November 2012,the cumulative amount of debit cards exceeded 30 million and an issue of growth is accelerating in China according to the statistics published by the People’s Bank of China.Compared with last year, its growth is accelerating.It shows such a situation that as a basic tool for replacing cash and checks to make purchases and transactions, the number of debit cards issued surge.In addition, in recent years the banks in order to unify and standardize business operations, enhance the ability to control risk, reduce operating costs of the entire system, started construction of a data center.The project centralized the important business owned by the bank to a plurality of data processing centers for processing.Debit card business as one of the basic core business of banks, also was in the focus of the column.However, with the further focusing on the banking business, the size of the debit cards have gradually increased.Data associated with debit card transactions continued to increase.Debit card system as a system processing debit card business bore a greater pressure.As a support system for banking IBM mainframe banking system has been put forward higher requirements in the business of data processing security, stability and efficiency.While facing these challenges,because of the banking system is inherently closed,almost demanding security,which makes the optimization and upgrading of the system tend to pay a lot of manpower, material cost.Which not only increases the capital investment, but also hinders the progress of system optimization.Based on the above scenario, we have developed this system in order to reduce the cost of upgrading existing systems.It also provides simulation environment for bank debit card system.When a bank debit card system needs upgrading, the system can be carried out on a simple simulation to obtain first-hand data, provide a reference for selecting the appropriate optimization.The system development process is as follows: After a study of the debit card business,we have established a system of processing debit card business model;We design and implement this system model on the IBM Z / OS system using CICS middleware and DB2 databases.The system can handle massive transaction data in batch processing mode,support multi-terminal concurrent transactions in the type of OLTP.In the system testing phase,configuring a reasonable proportion of the transaction, automatically generating massive test data according to the rules,building concurrent trading platform by simulate multiple terminals with TPNS to test the performance of the system. Finally, I have studied the test results.
