Analysis Of Mainframe Applications, Core Banking Systems

There has been more than half a century since human being had step into information age, computer has been not only for military and commerce use but also for family, further impact every corner of human society. With the widely used of PC, mainframe, as the important part of computer, has fade out from the sight of people, but he never disappeared and died out. In the field of commercial service, mainframe could be flourishing for a long time with the ability to supply a stable, reliable, secure platform for the application program of enterprise information system. For this, the critical system in many commercial banks at home and abroad has been run on mainframe application platform at the present time, in order to support concurrently access for system resources from up to ten million clients and application programs and deal with large amounts of data, ensure the security and reliability of system. For bank, deploying information system, especially critical system, on the application platform base on mainframe can efficiently integrate all kinds of subsystem in bank, and not only make daily operation management convenient, but promote stability and reliability of system, also can meet the trenchant hardware platform requirement for information system with increasingly huge and complex. Given the leading position of IBM in mainframe commercial field and most mainframe platforms set up on series of mainframe by his design and development, the environment I mentioned in this article basically preferred to the IBM Z series mainframe.This article focus on supplying a whole stable system which can run most business integrated information system for commercial bank. In order to reflect technology advancement of mainframe in commercial server field, this article elaborate principal, hardware structure, logical process procedure, key technology of critical system based on mainframe application platform, emphasize brilliant performance and design characteristic in structure of mainframe hardware. Also, critical system, in this article, has organically combined some new technology, so that it can reach higher system usability and stability. Compare with distributed computing mode, this article take critical system as an example, analyze mainframe technology advancement in detail while introducing the design and realization of system, clarify developing direction of mainframe in future.
