Research And Application Of High Availability Technology In Bank Transaction System

With the domestic capital market increasingly active in fund sales agency, represented by the securities business of banks trading volume showed the blowout growth. Several large banks in the domestic securities business as a result of system can not meet the high availability of external services of the system can not be serious. The same as the B/S structure of the individual housing loans of high-availability systems directly affect the banks of the individual housing loan business of the normal conduct. Since banks trading system is an important business banking system, the field of high availability technology and application of research has important practical significance.The high availability technology of applications in banking system and there are still many problems: low reliability of the banking transaction system, the banking transaction system in the event of failure of recoverability is not high, banking transactions in high-availability systems Cost-effective is not high.To address the above key issues, this thesis focused on the high availability in the banking system of trading. Failure of the banking system for transactions conducted in-depth analysis, Availability of high-technology was discussed, According to bank trading system of the characteristics of a cost-effective design of a dual-technology clusters bank trading system of high-availability framework. In this thesis, software engineering thinking of the main line, the bank trading system of high availability design were achieved under the framework of the banking and securities trading systems individual housing loans of high-availability systems.

Individual housing loans is a typical system based on J2EE standard B/S application framework, through a Web server clustering, Weblogic Application Cluster, database and application clusters Informix HDR laminar flow control mechanism and overtime to achieve the high availability of the system;3. Through the above two systems can be high-test verification of the banking transactions in high-availability systems for the effective assessment.
