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 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。由于國產關鍵基礎軟硬件產品不成熟以及缺乏系統性的兼容適 配，導致“核高基”面向黨政軍的 OA 應用示范課題在向國產平臺遷移測試驗證的 過程中暴露出大量系統整體性能不足的問題，主要體現在系統響應時間過長，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合攻關基 地并展開了相關聯合技術攻關工作。

本論文介紹分析了國產關鍵基礎軟硬件產品及集成應用現狀，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境和 OA 應用系統開展全面的測試 驗證工作，介紹了基于國產關鍵軟硬件的 OA 系統性能瓶頸分析方法，將一個完整 請求按執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。找到系統性能瓶頸后，針對系統瓶頸對 OA 系統展開相應的 服務器端和客戶端雙重調優，包括數據庫優化、中間件優化和 Web 客戶端優化等， 最后對優化后 OA 系統展開測試驗證，并與優化前系統各功能響應時間進行對比， 確認優化效果，總結出針對基于安全可靠軟硬件特性的 OA 系統整系統優化方法。

關鍵詞：安全可靠軟硬件黨政軍 OA性能瓶頸系統調優

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
