| The rapid development of the banking industry information has become an important driving force for promoting institutional innovation and corporate reengineering in the financial industry.In the earlier banking financial institutions,the main business operations were mainly characterized by a large number of data operations,but the data range was relatively small,and the processed data objects were mainly for current data or recent data.Some historical data is involved,which means that the range of data processed is fixed and within a controllable range.In recent years,with the development of the economy,various commercial banks have embarked on a data-centric approach.The centralized management of data has caused the rapid expansion of data volume.As the competition between various financial banking industries continues to increase,the banking system upholds the business philosophy of focusing on improving the quality of service customers and strengthening the business level.For modern banks,the safe,stable,and efficient operation of the banking system has gradually received more and more attention,and supervision and user needs have become increasingly demanding.How to improve the data security and efficiency of the bank's data center,and effectively control the risk of handling errors to adapt it to business needs,has become a major issue for data centers to ensure data security and improve data processing capabilities.Bank information system starts from the classification of computer clusters,and from the three levels of operating system,database and network,the high availability of each level is closely related to the redundancy and reliability of the overall software and hardware architecture design of the system.The operating system's cluster architecture utilizes the high-availability features of the operating system to share the external storage.The shared resources are dynamically migrated between different servers.The maximum amount of redundancy ensures the efficient and stable system resources.Operation,and the implementation of high availability requires comprehensive analysis on all aspects of the system hardware,network,application software,and database software to ensure timely recovery in the event of failure at each level,requiring system recovery time Short,and guarantee the consistency of data resources after restoration.This article discusses the related characteristics of the IBM DB2 database products that are widely used in the banking system,and analyzes the differences and linkages of its internal integrated cluster architecture.A total of DB2 HADR clusters and DB2 pureScale cluster architectures are involved in the database.Through comparative methods,the high availability features of the two architectures are analyzed and compared to find out their respective advantages and disadvantages.The details are as follows:(1)Introduce the IBM DB2 database product,including the function of the product and the introduction of the high-availability cluster architecture,judging its advantages from the features of each architecture;(2)Introduction to the banking system,and the current system Existence of the status quo,analysis;(3)Through the function analysis and discussion of the banking system,and business characteristics to identify the high availability features suitable for the long-term development of the system;(4)Use a comparative method to find the appropriate bank for IBM DB2 products The industry system features a high availability cluster architecture and proposes relevant countermeasures and recommendations. |
