...like other R/3 applications, is itself written in ABAP. Application Servers R/3 programs run on application servers. They are an important component of the R/3 System. The following sections describe application servers in more detail. Structure of an Application Server The application layer of an R/3 System is made up of the application servers and the message server. Application programs in an R/3 System are run on application servers. The application servers communicate with the presentation components, the database, and also with each other, using the message server. The following diagram shows the structure of an application server: [pic] The individual components are: Work Processes An application server contains work processes, which are components that can run an application. Each work process is linked to a memory area containing the context of the application being run. The context contains the current data for the application program. This needs to be available in each dialog step. Dispatcher Each application server contains a dispatcher. The dispatcher is the link between the work processes and the users logged onto the application server. Its task is to receive requests for dialog steps from the SAPgui and direct them to a free work process. In the same way, it directs screen output resulting from the dialog step back to the appropriate user. Gateway Each application server contains a gateway. This is the interface for the R/3 communication protocols...

Infrastructure and Security The network infrastructure is critical to the success of business. Day in and day out, users rely on the network to do their jobs well. Network uptime is crucial to the company’s operation and is becoming even more important as technology advances. Network infrastructure refers to the grouping of physical hardware and logical components which are needed to provide a number of features for the network, such as connectivity, routing and switching capabilities, network security, and access control. The physical infrastructure of the network refers to the physical design of the network together with the hardware components. The logical infrastructure of the network consists of all the software components required to enable connectivity between devices, and to provide network security. The network's logical infrastructure consists of software products and networking protocols and services. At a minimum, the network infrastructure should be capable of high availability to the three 9s (99.9%) of uptime. This equates to 8.76 hours of downtime per year for planned maintenance.

...| Edexcel Level 7EDSMLASSESSMENT ACTIVITY | | Unit Name: | STRATEGIC CHANGE MANAGEMENT | Unit Number: | 03 | Credits: | 10 | Assessor: | Prof. Krishna Mohan .M | Internal Verifier: | | Aim: Strategic change impacts on the human resources structure of the organization and this often means a restructuring of the workforce or changes in working practices. Almost inevitably, change will generate resistance from some, particularly those who feel that the change will have no positive benefits for them. Other people may resist change simply because they prefer status quo. Organizations need to ensure that they have strategies in place to manage resistance to change and this should be part of the overall model that they adopt for managing the change. Once in place, progress towards change will need to be monitored. Strategic change management is most effective when an organization actively seeks the participation of all relevant stakeholders. A change management strategy will be effective only if it has the support of all stakeholders. If they are to have a sense of ownership, stakeholders need to have the opportunity to contribute to the development of the change strategy. Learners will develop an understanding of the models of strategic change and the role that stakeholders play in this process. They will then examine the need for change in a selected organization and plan the implementation of a model for change. Summary of learning outcomes To achieve...

...PART ONE Introduction to Discrete-Event System Simulation 1 Introduction to Simulation A simulation is the imitation of the operation of a real-world process or system over time. Whether done by hand or on a computer, simulation involves the generation of an artificial history of a system, and the observation of that artificial history to draw inferences concerning the operating characteristics of the real system. The behavior of a system as it evolves over time is studied by developing a simulation model. This model usually takes the form of a set of assumptions concerning the operation of the system. These assumptions are expressed in mathematical, logical, and symbolic relationships between the entities, or objects of interest, of the system. Once developed and validated, a model can be used to investigate a wide variety of “what-if” questions about the realworld system. Potential changes to the system can first be simulated in order to predict their impact on system performance. Simulation can also be used to study systems in the design stage, before such systems are built. Thus, simulation modeling can be used both as an analysis tool for predicting the effect of changes to existing systems, and as a design tool to predict the performance of new systems under varying sets of circumstances. In some instances, a model can be developed which is simple enough to be “solved” by mathematical methods. Such solutions may be found by the use of differential calculus, probability...

...Practical 1 Practical 1.1 : Basic of Cluster Computing 1. INTRODUCTION 1.1 Background study Parallel computing has seen many changes since the days of the highly expensive and proprietary super computers. Changes and improvements in performance have also been seen in the area of mainframe computing for many environments. But these compute environments may not be the most cost effective and flexible solution for a problem. Over the past decade, cluster technologies have been developed that allow multiple low cost computers to work in a coordinated fashion to process applications. The economics, performance and flexibility of compute clusters makes cluster computing an attractive alternative to centralized computing models and the attendant to cost, inflexibility, and scalability issues inherent to these models. Many enterprises are now looking at clusters of high-performance, low cost computers to provide increased application performance, high availability, and ease of scaling within the data center. Interest in and deployment of computer clusters has largely been driven by the increase in the performance of off-the-shelf commodity computers, high-speed, low-latency network switches and the maturity of the software components. Application performance continues to be of significant concern for various entities including governments, military, education, scientific and now enterprise organizations. This document provides a review of cluster computing, the various types...

...UCSB Computer Science Technical Report 2010-05. Who’s Driving this Cloud? Towards Efficient Migration for Elastic and Autonomic Multitenant Databases Aaron Elmore Sudipto Das Divyakant Agrawal Amr El Abbadi Department of Computer Science University of California, Santa Barbara, CA, USA {aelmore, sudipto, agrawal, amr}@cs.ucsb.edu Abstract The success of cloud computing as a platform for deploying webapplications has led to a deluge of applications characterized by small data footprints but unpredictable access patterns. An autonomic and scalable multitenant database management system (DBMS) is therefore an important component of the software stack for platforms supporting these applications. Elastic load balancing is a key requirement for effective resource utilization and operational cost minimization. Efficient techniques for database migration are thus essential for elasticity in a multitenant DBMS. Our vision is a DBMS where multitenancy is viewed as virtualization in the database layer, and migration is a first class notion with the same stature as scalability, availability etc. This paper serves as the first step in this direction. We analyze the various models of database multitenancy, formalize the forms of migration, evaluate the offthe-shelf migration techniques, and identify the design space and research goals for an autonomic and elastic multitenant database.
