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 technologies.open standards，interoperability- and object-oriented technologies.Its 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.
1.Why DME Works
DME builds on existing standards.It 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 process.As a result, DME maps to your computing environment and manages growth inmulit-vendor systems and networks.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 market.This will result in lower costs and better solutions for users.
2.The 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.
3.What 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 vendors.Complete 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 vendors.Put 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 systems.These 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 issues.It 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 opera-dons.Distributed systems management allows for growth in the number of managed systems while reducing support requirements and lowering costs.It 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.
分布式管理环境
随着分布式多厂商计算环境的出现创造一种有利于分布式多厂商计算环境有效管理的标准框架便成为一件座予以最优先考虑的事。因此，一些主要厂商通过 开放软件基金会(OSF)制定了一套称为分布式管理环境(DME)的、独立于厂商的开放标准。
DME被认为能最有效地利用当今先进的分布式计算技术、开放标准、互操作性和面向对象的技术DME的标准化框架代表了工业界对于开放管理的应用程序接口(APL)和协议的一致意见DME是一种随技术发展而演进的“活”标准，能把最新的工业发展增加进去。
1.DME何以能发挥作用
DME以现有标准为基础。它并不替代其他标准，而是一种既包含现有的SNMP(简单网络管理协议)和CMIP(公共管理信息协议) 标准有支持由网络管理论坛、 X/Open及其他组织开发的补充手段。
DME是在众多厂商达成一致意见的基础上产生的。因此，DME也反映了你的计算环境，并能驾驭多厂商系统和网络方面的发展。又因为DME是工业异一致意见的产物，所以它会加速你组织内达成一致意见。
DME是以各方面的要求为基础的这些要求是为达到特定目标并满足实际需求，在工业界以开放的方式逐渐形成的。
DME是独立于厂商的，因此能强化管理市场的竞争。这将降低成本，并为用户提供较好的解决方案。
2.种种优点
DME具有如下多方面的优占.
(1)可伸缩的分布式体系结构、能容纳多厂商网络和分布式系统的发展。
(2)可通过实现公共管理服务及标准化的协议和对象定义来改善管理、互操作性和集成能力。
(3)可减少系统管理和训练的时间与费用。
(4)可提供利用面向对象设计的、紧密集成的解决方案，以使可伸缩的分布式多厂商体系结构的集成更方便、更灵活。
(5)基干标准的反向兼容性能延长系统的寿命。
3.你当今能干的工作
无论你在哪里开发网络，我们建议你在制定企业管理战略时对DME作出评价。DME的某些部分在1993年期间将可从若干厂商那里得到。DME的全面实现要到1994年才开始。
分布系统所要求的管理水平和可用性与信息、系统历来在主机环境中所提供的相同。不过，从技术上来说，分布系统管理方法与集中式系统管理方法是大相径庭的。
要管理的硬件和软件资源增多，非常分散。而且是由各样各样的制造商所提供。总之，老式的系统管理方法无法用来管理这些新的分布系统。人们需要一种新的方法。
与集中的主机环境相比，分布系统的跟踪与干预工具仍然略显原始些，但信息系统专业人员所必须管理的系统的数量和种类却在不断增加。同时，人们希望 信息系统专业人员提供备份与故障恢复服务、具有故障隔离与修理能力，并提供各种升一级工作， 用户希望提供的这些服务的水准 能达到与由集中系统提供的服务类似。这些要求全都预示着要增圳管理和支持费用.
如果这些系统的管理很差，由此造成的费用会把通过小型化实现的成本降低抵消，这种可能性是实际存在的。
有效的分布式管理，是针对解决这些问题的，就从能够对信息、技术资源和成本进行有效管理来看，分布系统管理能使分布计算给业务上带来许多好处。
分布系统管理措施如果得力，在保证生产与质量方面的服务水准可以达到与传统主机作业提供的服务水准相同。分布系统管理，既能增加被管理系统的数 量也能降低支持要求和成本。它能提供远程系统的可用性、安全性和完整性。它还能提供远程系统管理，因而能全面了解整个企业情况，更有效地使用有限的支 持资源，并为更高级的自动化管理奠的基础。
