16、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(dāng)用戶量大時，也可以使用備用服務(wù)器，兩個服務(wù)器進行同步數(shù)據(jù)存 儲，如果一臺服務(wù)器出錯時，可以轉(zhuǎn)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(guān)問題。Due to the rapid development of modern computer science and technology, previous data backup and managers have been unable to meet the user requirements of the existing system,

When the databaseis paralyzed by rapidly switching system libraries, which can effectively reduce the loss of data. When the user capacity, you can use the backup server, two servers synchronize

The technology used in the existing

21、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 for system maintenance.3）恢復(fù)及再啟動技術(shù)Recovery an

22、d re-start technology由于采取的是低端服務(wù)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(shè)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(shè)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，系統(tǒng)
