描述分佈式管理環境的計算機英語
計算機英語其實有點難學習，但是大家不要灰心，小編今天就給大家整理了有關於計算機的英語，歡迎大家閱讀
Distributed Management Environment
With the emergence of distributed multi- vendor computing environments, the creation of a standards framework to facilitate their effective management became a top priority. As a result, leading vendors, working through the Open Software Foundation(OSF) have developed a set of open, vendor-neutral standards known as Distributed management Environment (DME).
DME was conceived to get the most out of to-day's advanced distributed computing standards，interoperability- and object-oriented standardized framework represents an industry consensus on application pro-gram interfaces (APIs) and protocols for open man-agreement. DME is a 'living' standard, evolving as technologies evolve enhancing the latest industry developments.
DME Works
DME builds on existing is not an alternative to other standards. Rather, it represents acomplementarv approach that encompasses existing SNMP and CMIP standards and endorses interfaces devised by the Network Management Forum X/Open and others.
DME is the product of a multi-vendor, consent-sus-based a result, DME maps to your computing environment and manages growth inmulit-vendor systems and because DME is the product of industry consensus it accelerateates the process of reaching consensus within your organization.
DME is based on a comprehensive set of requirements developed through an open industry process to meet specific objectives and address real needs.
DME is vendor neutral. It enhances competition in the management will result in lower costs and better solutions for users.
Benefits
Dame's wide-ranging benefits include：
(1)A scaleable, distributed architecture that can accommodate growth in multi-vendor networks and distributed systems.
(2)Better management, interoperability and integration through the implementation of common management services and standardized protocol adobe definitions.
(3)Reductions in time and costs for system administration and training.
(4)Tightly integrated solutions utilizing objectoriented design, for easier and more flexible integration of scaleable，distributed，multi-vendor architectures
(5)Greater longevity of systems resulting from standards-based, backwards compatibility.
you can do today
No matter where you are in the development of your network, we suggest evaluating DME as you build your enterprise management strategy. Portions of the DME will be available during 1993 from number of lete implementations ode win begin appearing in 1994.
Distributed systems demand the same level of management and availability that IS has historically provided in a mainframe environment. Yet the technicely approach to distributed systems management is fundamentally different from that applied to central-sized system.
Hardware and software resources to be managed tend to be more numerous, widely-dispersed and provided by a wide variety of sumply, old approaches to systems management cannot be incrementally extended to manage these new distributed systems.A new approach is required.
When compared to centralized mainframe environment, tracking and intervention tools for distributed systems management still appear somewhat primitive even as the number and variety of systems IS professionals are expected to provided backup and recovery services，fault isolation and repair capability-ties, and updating procedures that provide levels of service similar to those users have come to expect from centralized e demands all threaten to increase administrative and support expenses.
If these systems are poorly managed. there's real chance such expenses may actually erase the cost reductions achieved through downsizing .
Effective distributed systems management ad-dresses these provides the considerable business benefits of distributed computing with context that allow for effective management of IT resources and cost.
A strong distributed systems management policy will result in the same level of production-quality service provided by traditional mainframe ributed systems management allows for growth in the number of managed systems while reducing support requirements and lowering increases system availability, security and integrity. It provides remote systems management, which intern provides an enterprise-wide perspective, the more effective use of limited support resources，and the basis for higher levels of automated management.
分佈式管理環境
隨着分佈式多廠商計算環境的出現創造一種有利於分佈式多廠商計算環境有效管理的標準框架便成爲一件座予以最優先考慮的事。因此，一些主要廠商通過 開放軟件基金會(OSF)制定了一套稱爲分佈式管理環境(DME)的、獨立於廠商的開放標準。
DME被認爲能最有效地利用當今先進的分佈式計算技術、開放標準、互操作性和麪向對象的技術DME的標準化框架代表了工業界對於開放管理的應用程序接口(APL)和協議的一致意見DME是一種隨技術發展而演進的“活”標準，能把最新的工業發展增加進去。
何以能發揮作用
DME以現有標準爲基礎。它並不替代其他標準，而是一種既包含現有的SNMP(簡單網絡管理協議)和CMIP(公共管理信息協議) 標準有支持由網絡管理論壇、 X/Open及其他組織開發的補充手段。
DME是在衆多廠商達成一致意見的基礎上產生的。因此，DME也反映了你的計算環境，並能駕馭多廠商系統和網絡方面的發展。又因爲DME是工業異一致意見的產物，所以它會加速你組織內達成一致意見。
DME是以各方面的要求爲基礎的這些要求是爲達到特定目標並滿足實際需求，在工業界以開放的方式逐漸形成的。
DME是獨立於廠商的，因此能強化管理市場的競爭。這將降低成本，併爲用戶提供較好的解決方案。
2.種種優點
DME具有如下多方面的優佔.
(1)可伸縮的分佈式體系結構、能容納多廠商網絡和分佈式系統的發展。
(2)可通過實現公共管理服務及標準化的協議和對象定義來改善管理、互操作性和集成能力。
(3)可減少系統管理和訓練的時間與費用。
(4)可提供利用面向對象設計的、緊密集成的解決方案，以使可伸縮的分佈式多廠商體系結構的集成更方便、更靈活。
(5)基幹標準的反向兼容性能延長系統的壽命。
3.你當今能幹的工作
無論你在哪裏開發網絡，我們建議你在制定企業管理戰略時對DME作出評價。DME的某些部分在1993年期間將可從若干廠商那裏得到。DME的全面實現要到1994年纔開始。
分佈系統所要求的管理水平和可用性與信息、系統歷來在主機環境中所提供的相同。不過，從技術上來說，分佈系統管理方法與集中式系統管理方法是大相徑庭的。
要管理的硬件和軟件資源增多，非常分散。而且是由各樣各樣的製造商所提供。總之，老式的系統管理方法無法用來管理這些新的分佈系統。人們需要一種新的方法。
與集中的主機環境相比，分佈系統的跟蹤與干預工具仍然略顯原始些，但信息系統專業人員所必須管理的系統的數量和種類卻在不斷增加。同時，人們希望 信息系統專業人員提供備份與故障恢復服務、具有故障隔離與修理能力，並提供各種升一級工作， 用戶希望提供的這些服務的水準 能達到與由集中系統提供的服務類似。這些要求全都預示着要增圳管理和支持費用.
如果這些系統的管理很差，由此造成的費用會把通過小型化實現的成本降低抵消，這種可能性是實際存在的。
有效的分佈式管理，是針對解決這些問題的，就從能夠對信息、技術資源和成本進行有效管理來看，分佈系統管理能使分佈計算給業務上帶來許多好處。
分佈系統管理措施如果得力，在保證生產與質量方面的服務水準可以達到與傳統主機作業提供的服務水準相同。分佈系統管理，既能增加被管理系統的數 量也能降低支持要求和成本。它能提供遠程系統的可用性、安全性和完整性。它還能提供遠程系統管理，因而能全面瞭解整個企業情況，更有效地使用有限的支 持資源，併爲更高級的自動化管理奠的基礎。
