【正文】 cket correspondence synchronous realize according to Socket correspondence of the data is synchronous, the server carried to make use of the tool that there has been well with perl phoic and vivid。使用 COM 組件可以避免在多個(gè) ASP 文件中使用 Winsock ActiveX 控件進(jìn)行編程，實(shí)現(xiàn)代碼復(fù)用。該 Intra 工具要求與 CR 相關(guān)的人員主動使用 DDTS 工具查詢相關(guān) CR 的信息，并將信息在 Web 錄入頁面上輸入到 Web 服務(wù)器上的本地?cái)?shù)據(jù)庫，供 CR 跟蹤使用。譯文基本準(zhǔn)確，該同學(xué)認(rèn)真地完成了外文資料翻譯任務(wù)。 2. 幾種跨平臺數(shù)據(jù)同步方案 在介紹常用跨平臺數(shù)據(jù)同步方法之前有必要簡要介紹一下所開發(fā)的Intra 自動化工具的設(shè)計(jì)目的和狀況。編程過程中 ，對建立連接時(shí)產(chǎn)生的 EINTR 錯(cuò)誤的處理和對 SIGCHLD 信號的處理是關(guān)鍵，如果處理不好，將會出現(xiàn)無法多次連接和連接關(guān)閉后導(dǎo)致僵死進(jìn)程的情況。Two what certain sections uses are the third square the development of according to the tool( such as the tool of DDTS) of the database, its section oneself management without database legal power, as a result also can39。On the other hand, at make selection own Intra announce the terrace at the same time, share with other section the section of the data originally too the ground of cowgirl chose own data announces the terrace. At the same time, modern business enterprise internal and each section a data for being in conjunction with work too more and more closely, different section usually needing visitting can renew synchronously, or at least can in certain time partition the proceeding data is big and part of databases product has own according to TCP/ IP interview method, the strategy in enterprise security is next, each section will usually change to install to the port of IP interview method, bining to develop an own internal data interview tool。 在開發(fā)過程中，采用基于 Socket 通信的跨平臺數(shù)據(jù)同步方法。 同時(shí)，現(xiàn)代企業(yè)內(nèi)部各部門之間的協(xié)同工作也越來越密切，不同部門之間通常需要訪問的數(shù)據(jù)能同步更新，或者至少能在一定的時(shí)間間隔內(nèi)進(jìn)行數(shù)據(jù)同步。 隨著現(xiàn)代企業(yè)朝著國際化、集團(tuán)化的方向發(fā)展，現(xiàn)代企業(yè)內(nèi)部各部門之間出現(xiàn)了分工細(xì)密化和分布全球化的趨勢。 考慮到大部分的數(shù)據(jù)庫產(chǎn)品都有自己的基于 TCP/IP 的訪問方式，要求相關(guān)部門開放數(shù)據(jù)庫的 IP端口訪問及受限的用戶名和密碼給 Intra 開發(fā)人員也許是一個(gè)簡單的實(shí)現(xiàn)跨平臺數(shù)據(jù)同步的方法。在設(shè)計(jì)的自動化工具中，利用 Windows NT 的Schedule Service 實(shí)現(xiàn) CR 的定時(shí)自動同步、更新及發(fā)送通知 Email 等任務(wù)，使用 ASP 設(shè)計(jì)對本地?cái)?shù)據(jù)庫訪問的交互頁面進(jìn)行 CR 跟蹤。t link with link to cause the progress after closing many develop process, the usage popen function circulates a perl the data that script need when obtaining bines its pass the piping return the procedure, that script usage DDTS tool to obtain the kind of method made use of to there has been the tool well with the perl phoic and vivid, lowering the difficulty of insuring the hears the procedure to circulate always, adopting to increase in system in the host of UNIX crontab an instruction make the each in system penny clock check 偵 hear the procedure scksvr whether in the movement, and start afresh under the situation of causing break among them the movement unusually because of the system. The customer carries to circulate on the terrace of Windows NT, adoption Microsoft Visual C++ of the ATL( Active Template Library) template COM development makes into a COM module with the MFC Socket plait usage COM module can avoid using in several ASPs document the Winsock ActiveX controls the piece proceeds to weave the
