【摘要】：當前,信息系統(tǒng)已廣泛應用于各行各業(yè),其為業(yè)務提供便捷性的同時,也為業(yè)務的連續(xù)性帶來了隱患。因此,信息系統(tǒng)的可靠性直接影響著所承載業(yè)務的穩(wěn)定性,而要保障信息系統(tǒng)的持久有效運行,就需要了解信息系統(tǒng)的實際運行情況,通過數(shù)據(jù)反映信息系統(tǒng)的運行水平,及時發(fā)現(xiàn)信息系統(tǒng)運行過程中的薄弱環(huán)節(jié)等問題并予以解決。本文以西京學院目前運行的信息系統(tǒng)為背景,首先對網(wǎng)絡設備進行了 N-1故障分析,并基于分析結(jié)果設計了西京學院信息系統(tǒng)的冗余方案;針對信息系統(tǒng)運行可靠性,從功能和過程兩個角度進行了分析,運用Petri網(wǎng)理論對信息系統(tǒng)運行過程建立了可靠性模型,定量衡量信息系統(tǒng)的運行過程情況,通過對信息系統(tǒng)運行可靠性的控制來保障信息系統(tǒng)在運行過程中的可靠性;并對冗余測試的相關技術(shù)進行了研究,構(gòu)建了信息系統(tǒng)冗余功效測試方案。本文具體研究內(nèi)容如下:1.信息系統(tǒng)N-1自動故障模擬方法及分析。選擇西京學院外網(wǎng)門戶網(wǎng)站系統(tǒng)、OA辦公系統(tǒng),通過LoadRunner工具對網(wǎng)絡拓撲中關鍵鏈路和關鍵節(jié)點(服務器和核心交換機)進行故障設定、故障計算、故障校驗、動作模擬、負載校驗、事故對策形成、事故對策形成、分析報告輸出。針對信息門戶系統(tǒng)和OA辦公系統(tǒng),提出了信息系統(tǒng)N-1故障模擬方法方案,并進行仿真實驗。2.信息系統(tǒng)冗余方案研究。分析了西京學院信息系統(tǒng)的現(xiàn)狀,分析目前學校的信息系統(tǒng)以及網(wǎng)絡設備的單點隱患;然后,針對學校的OA辦公系統(tǒng)、教務管理系統(tǒng)和學校門戶網(wǎng)站,提出了具體的冗余設計方案。3.基于Petri網(wǎng)的信息系統(tǒng)可靠性評估模型。以西京學院信息系統(tǒng)運行為背景進行了故障分析,基于Petri網(wǎng)的基本理論,以西京學院財務管理系統(tǒng)為背景,提出了基于Petri網(wǎng)的信息系統(tǒng)運行可靠性評估模型,并針對數(shù)據(jù)中心平臺的財務管理系統(tǒng)進行了仿真實驗。
[Abstract]:At present, information system has been widely used in various industries, which provides convenience for business, but also brings hidden trouble to business continuity. The reliability of information system has a direct impact on the stability of the carrying business. To ensure the effective and lasting operation of the information system, we need to know the actual operation of the information system. Through the data reflect the level of the information system, timely find out the weak links in the process of information system and solve the problem. This paper takes the information system of Xijing University as the background. First, the N-1 fault analysis of network equipment is carried out, and the redundancy scheme of Xijing University information system is designed based on the analysis results. Aiming at the operational reliability of information system, this paper analyzes the function and process of the information system, and establishes the reliability model of the information system by using the theory of Petri net. The operation process of the information system is quantitatively measured, and the reliability of the information system is guaranteed by controlling the reliability of the information system. The related technology of redundancy testing is also studied. This paper constructs the information system redundancy test scheme. The specific research content of this paper is as follows: 1. Information system N-1 automatic fault simulation method and analysis. Choose Xijing University Web portal system OA office system. Through LoadRunner tools, the key links and key nodes (server and core switch) in the network topology are set up, fault calculation, fault check, action simulation, load check. Accident countermeasure formation, accident countermeasure formation, analysis report output. Aiming at information portal system and OA office system, an information system N-1 fault simulation scheme is put forward. And carry on the simulation experiment .2.The information system redundancy scheme research. Analyzed the Xijing University information system present situation, analyzed the school information system and the network equipment single point hidden danger; Then, for the school OA office system, educational administration system and school portal. This paper puts forward the specific redundant design scheme .3. the reliability evaluation model of information system based on Petri net. The fault analysis is carried out on the background of the information system operation of Xijing University. Based on the basic theory of Petri net and taking the financial management system of Xijing University as the background, this paper puts forward the reliability evaluation model of information system based on Petri net. The simulation experiment is carried out for the financial management system of the data center platform.
