1、7 系統(tǒng)出錯處理設計 System error handling design（撰寫人：楊林森 3112101126 Yanglinsen 2102-011-0300）7.1 出錯信息Error message在軟件的開發(fā)過程中， 需要對軟件中存在的漏洞立即進行處理， 即使一個很小的漏洞，也會造成整個軟件開發(fā)系統(tǒng)的垃圾資源無限增多， 最終可能會導致系統(tǒng)的癱瘓。因此在系統(tǒng)設計中， 對擬開發(fā)系統(tǒng)要注意數(shù)據(jù)的約束性。 為了進行數(shù)據(jù)統(tǒng)一收集和規(guī)范數(shù)據(jù)統(tǒng)一格式方面管理者的處理， 針對存在的安全隱患， 本項目組進行了統(tǒng)一約束規(guī)范。 同時，項目組也應該解決 Web服務器端的信息安全問題，這樣才能更好的運用管

2、理系統(tǒng)， 從而減少系統(tǒng)的維修次數(shù)， 確保系統(tǒng)的安全使用。In the software development process, the need for software vulnerabilities that exist in immediate treatment, even a small flaw will cause garbage resources of the entire software development system and the infinite increase, may eventually lead to paralysis of the system

3、. Therefore, system design, system development should pay attention to the proposed binding data. In order to deal with a unified data collection and standardized data formats unified manager for security risks, the project team conducted a unified constraint specification. Meanwhile, the project te

14、來提高安全水平，這是用戶和信息服務管理部門可做得到的。All systems, regardless of which way the use of development are inevitable weaknesses. Therefore, not only in the information management system at this level and be designed to review and propose security issues in computing center at this level (if applicable, including r

15、emote device). By identifying weaknesses in the system to reduce the risk of security violations, and to take the necessary precautionary measures to improve the safety level, which is the user and theinformation services department can do it.1）后備技術Back-up technology由于現(xiàn)代計算機科學技術的快速發(fā)展， 以往的數(shù)據(jù)備份已經(jīng)不能滿足用戶

16、和管理者對現(xiàn)有系統(tǒng)的要求， 現(xiàn)在的技術一般是進行系統(tǒng)數(shù)據(jù)庫的實時備份和備份服務器。當數(shù)據(jù)庫癱瘓時， 通過快速進行系統(tǒng)庫的切換， 這樣可以有效的減少數(shù)據(jù)的丟失。當用戶量大時， 也可以使用備用服務器， 兩個服務器進行同步數(shù)據(jù)存儲，如果一臺服務器出錯時， 可以轉換到另一臺進行相同的操作， 讓用戶不需要因癱瘓而面臨網(wǎng)頁打不開、數(shù)據(jù)丟失等相關問題。Due to the rapid development of modern computer science and technology, previous data backup and managers have been unable to meet

17、 the user requirements of the existing system, and now the technology is generally carried out in real-time backup system database and backup servers. When the database is paralyzed by rapidly switching system libraries, which can effectively reduce the loss of data. When the user capacity, you can

18、use the backup server, two servers synchronize data storage, if a server error, can be converted to another the same operation, so that the user does not open the page because of paralysis of face , data loss and other related issues.2）降效技術Drop-efficient technology通常情況下系統(tǒng)的管理員都不是專業(yè)的計算機人員，對計算機專業(yè)的知識了解相

19、對較少。在面對系統(tǒng)癱瘓等錯誤時，都不知道如何去解決問題。如今，隨著計算機科學技術的飛速發(fā)展， 為了讓系統(tǒng)用戶能夠自行解決運行過程中遇到的問題，大多采取小型服務器作為后備技術。這項技術在現(xiàn)有的開發(fā)系統(tǒng)中使用很廣泛，當然備用的服務器從價格上考慮，可能不如主服務器， 也可能會降低工作效率，但是從數(shù)據(jù)的完整性和安全出發(fā)，可以讓維修人員有更多時間進行系統(tǒng)的維護。Normally the system administrator is not a professional computer staff, relatively little computer expertise to understand.

20、 In the face of system failures and other errors, do not know how to solve the problem. Nowadays, with the rapid development of computer science and technology, in order to allow system users to solve problems encountered during the operation on their own, mostly taken small server as a backuptechno

21、logy. The technology used in the existing development systems is extensive, of course, the backup server from the price considerations, may not be as the primary server, it may decrease work efficiency, but starting from the integrity and security of data, allowing maintenance personnel more time fo

22、r system maintenance.3）恢復及再啟動技術Recovery and re-start technology由于采取的是低端服務器， 同時進行數(shù)據(jù)庫的實時備份。 這樣在系統(tǒng)維護好完成后，可以很快的進行數(shù)據(jù)同步，同時也可以很快的進行系統(tǒng)的運行。To adopt a low-end server, while the real-time backup of the database. So that system maintenance is completed, you can quickly synchronize data, but also can be quickly carried out the operation of the system.7.3系統(tǒng)維護設計System maintenance design信息管理系統(tǒng)不同于其他系統(tǒng)，它并不是一勞永逸的最終系統(tǒng)。在它的運行過程中，還有大量運行管理、系統(tǒng)維護、系統(tǒng)設置等工作要做。交付使用的信息管理系統(tǒng)跟工業(yè)產(chǎn)品不同， 工業(yè)產(chǎn)品可以先生產(chǎn)一個樣品，經(jīng)過試驗、改進再正式投入批量生產(chǎn)， 而信息管理系統(tǒng)它需要在用戶使用過程中不斷完善。系統(tǒng)維護包括程序的維護、數(shù)據(jù)文件的維護、代碼的維護等，而且系統(tǒng)的修改，往往會造成系統(tǒng)程序、文件、代碼的修改。因此
