VR机制在金融业主机系统中的研究与实现
|
摘要
如今,金融行业中的各类业务交易和海量数据都依赖于电子信息化处理。因此为了能及时响应和处理这些交易,各大金融机构都使用主机系统来处理核心数据。但是如何保障数据安全便成为了问题,一旦信息系统崩溃或是遭到其他原因引起的灾难,则所有的交易信息都将荡然无存,因此金融机构应当设置相应的容灾机制,以便发生灾难时能够恢复业务交易和对外服务的功能。
本文通过对大型金融机构中各种容灾方案的分析,比较了各种灾难恢复机制的优缺点和适用场合,提出了从中间件的角度进行灾难恢复的方法。同时,本文通过对CICSVR的原理及方法、主机系统联机交易流程、文件数据集存储结构的分析,针对金融行业主机系统中联机数据的安全保障问题,提出了一种将CICSVR机制应用在金融行业主机系统灾难恢复中的方法,并将这一机制成功地运用在某银行江苏分行会计应用子系统中。本文详细论述了CICSVR机制在金融业主机系统中的研究与实现过程,并对联机文件设置CICSVR所需要消耗的磁盘空间以及如何在所有联机文件中选择重要的关键文件设置CICSVR机制才能达到最高的性能作了深入的探讨。
本文研究的目的是利用CICSVR的方法建立主机系统联机文件在金融机构对外服务过程中的安全保障机制。本文研究工作的意义在于,从恢复底层数据文件的角度来进行金融机构信息系统的灾难恢复,采用CICSVR机制对联机文件进行容灾备份以及数据恢复。CICSVR机制在某银行会计系统中的成功投入使用验证了该方法的可行性与实用性。
Nowadays, various types of transactions and hundreds of thousands of data in financial industries are handled by computers. In order to deal with these transactions, many major financial industries have used Mainframe systems to deal with important or core data. Then the security of these data becomes a problem. If the information system met crashes or was out of control because of different kinds of reasons, all of data stored in the system would not be useful any more. Thus, it is necessary for financial industries to build a mechanism which is called disaster recovery. Even if the information system takes some crashes, this mechanism can be used to recover important data so that financial services can be supported as usual.
This thesis introduces some disaster-tolerant techniques used by major financial industries. We analyze their differences and conclude a disaster recovery method in the view of the middleware. Based on the principle of the CICSVR method, data storing in Mainframe systems and the structure of online files, we propose to apply CICSVR to Mainframe systems in financial industries. In addition, some formulas are used to compute disk space which would be additionally consumed by the CICSVR method. We also show that one should choose key files to set this method and to achieve the best performance. Finally, we apply this method to a certain banking system successfully.
The purpose of this thesis is to apply CICSVR method to build efficient security systems for Mainframe Systems which are used by financial industries. We implement the disaster recovery of information systems in view of data. Because these data files are just stored on DASD, we can recover businesses by recovering the data files. The method is proved by the successful implementation of CICSVR method in the accounting application of a certain bank.
