摘要

“十二五”期間，基于國家重大科技專項“核高基”前一階段的基礎軟硬件產(chǎn) 品技術成果，以應用示范為牽引，全面驗證、推廣“十一五”“核高基”成果成為 工作重點和主題。由于國產(chǎn)關鍵基礎軟硬件產(chǎn)品不成熟以及缺乏系統(tǒng)性的兼容適 配，導致“核高基”面向黨政軍的 OA 應用示范課題在向國產(chǎn)平臺遷移測試驗證的 過程中暴露出大量系統(tǒng)整體性能不足的問題，主要體現(xiàn)在系統(tǒng)響應時間過長，基本 不能用。為了解決應用推進問題，由工信部牽頭組織了安全可靠軟硬件聯(lián)合攻關基 地并展開了相關聯(lián)合技術攻關工作。

本論文介紹分析了國產(chǎn)關鍵基礎軟硬件產(chǎn)品及集成應用現(xiàn)狀，研究分析了 OA 應用的需求，對基于安全可靠軟硬件的運行環(huán)境和 OA 應用系統(tǒng)開展全面的測試 驗證工作，介紹了基于國產(chǎn)關鍵軟硬件的 OA 系統(tǒng)性能瓶頸分析方法，將一個完整 請求按執(zhí)行流程劃分成若干時間片，并分段測試其消耗時長，從而定位瓶頸所在層 和具體性能瓶頸所在。找到系統(tǒng)性能瓶頸后，針對系統(tǒng)瓶頸對 OA 系統(tǒng)展開相應的 服務器端和客戶端雙重調(diào)優(yōu)，包括數(shù)據(jù)庫優(yōu)化、中間件優(yōu)化和 Web 客戶端優(yōu)化等， 最后對優(yōu)化后 OA 系統(tǒng)展開測試驗證，并與優(yōu)化前系統(tǒng)各功能響應時間進行對比， 確認優(yōu)化效果，總結(jié)出針對基于安全可靠軟硬件特性的 OA 系統(tǒng)整系統(tǒng)優(yōu)化方法。

Abstract

Because of the foundational software and hardware products and technologic al achievements of the previous stage of the national major science and technolo gy projects " electronic components,chip and software", to demonstrate and popul arize the achievements of "11th Five-Year Plan" and "electronic components,chip and software" comprehensively becomes the focus and theme during the "12th Fi ve-Year Plan" period. Due to the immaturity of domestic key hardware and soft ware products and the lack of systematic compatible adapter, resulting in the "el ectronic components,chip and software" OA application demonstration revealed a lot less overall system performance issues in the domestic platform migration, tes ting and validation process when oriented to party, government and military, whi ch mainly reflected in that the system response time is too long so that they ca n not be used basically. In order to solve the problem of application promotion, MIIT organizes the joint research base of safe and reliable software and hardwar e and strives to make breakthrough of relevant joint techniques.

This paper introduces the analysis of domestic key software and hardware p roducts and the status of application integrated, this paper researches and analyze s the needs of OA applications. this paper will carry out
