2.3.2. Key components of ESAP technical platform
The 5 key components of the new platform for ESAP applications are described below. All together, these components enable the delivery of much more flexible, resilient, highly scalable and performant infrastructure that can support ESAP and other applications with substantially decreased TCO.
2.3.2.1. 64-bit Linux
Linux is commonly recognised as a most cost-effective Open Source operating system for business-critical applications. This platform allows to directly address the large memory, facilitating the consolidation of non-production (development and test) application instances with very low CPU consumption but relatively high memory utilisation without using special and rather expensive server virtualisation software. Linux platform is sufficiently mature, it is less vulnerable to the security threats than Windows, and allows to use SAP Adaptive Computing (see item 5) that is not fully supported on Windows platform. Finally, Linux has native support for NFS protocol, which is crucial to enable the efficient use of NAS. This is a key factor driving the choice of Linux platform instead of competing MS Windows. It allows using NAS directly connected to the Linux servers without iSCSI overhead that would be non-avoidable in the case if Windows platform was used.
2.3.2.2. AMD Opteron
Despite Linux can perfectly run on 64-bit Intel servers as well, AMD provides better performance/cost ratio and is more mature platform for 64-bit computing. Linux on AMD is fully certified by SAP platform for SAP applications. ESAP runs on 64-bit Red Hat Enterprise Linux 4.0 Update 5.
2.3.2.3. Oracle Real Application Clusters (RAC)
Oracle RAC is the database clustering solution which can run on commodity platform without any special requirements to the hardware or operating system software. All the nodes of cluster are operating concurrently with automatic load balancing. The load is automatically redistributed without database services outage in the case of the cluster node failure or the new node introduction. This ensures high resilience and virtually unlimited horizontal scalability of the database layer using small cheap unified commodity servers. Oracle RAC is fully certified by SAP as a DB platform for SAP applications.
2.3.2.4. NetApp storage
NetApp provides fully certified by SAP and Oracle NAS solution which can not be treated as a commodity, but is very widely used for business-critical applications and has some unique features not available from any other storage vendor. Particularly, FlexClone allows sharing the copy of production DB between several non-production instances. This copy may be represented by maintained in the real-time at the failover site remote replica of the production DB, making the DR almost instant (realistically, within 3 hours if dedicated DR hardware is not available and failover happens to the non-production processing environment).
The project will bring several changes to the company; it will first expand the current physical IT environment. It will provide the ability to increase the storage capacity of the current storage requirement and expected growth of data, while establishing a new data warehouse and business analytics applications and user interfaces. The project will also improve security by establishing security policies and it will leverage newer cloud based technology to provide a highly redundant, flexible and scalable IT environment while also allowing the ability to establish a low cost disaster recovery site.
“Ubuntu is probably the most well-known Linux distribution. Ubuntu is based on Debian, but it has its own software repositories. Much of the software in these repositories is synced from Debian’s repositories. The Ubuntu project has a focus on providing a solid desktop (and server) experience, and it isn’t afraid to build its own custom technology to do it. Ubuntu used to use the GNOME 2 desktop environment, but it now uses its own Unity desktop environment. Ubuntu is even building its own Mir graphical server while other distributions are working on the Wayland. Ubuntu is modern without being too bleeding edge. It offers releases every six months, with a more stable LTS (long term support) release every two years. Ubuntu is currently working on expanding the Ubuntu distribution to run on smartphones and tablets (hottogeek).” Ubuntu has a reputation for ease of use, which is why it’s popular on many desktops and servers. Ubuntu also helps users keep up with the latest software versions by releasing updates on a regular schedule. The drawback of frequent updates is that it's harder to keep bugs from slipping into the mix. To this end Ubuntu releases an LTS version periodically, which stands for "Long-Term Support". The LTS version uses package versions that are considered more stable than cutting-edge, making it more suitable for use on a production server than the interim Ubuntu releases. If you're completely lost as to which distribution to run Ubuntu LTS is a safe place to start. Its widespread adoption means there are several forums and sites on the Internet that provide help resources for Ubuntu
In 1994, Jim Donehey was brought in to update Capital One’s IT system. His solution was to replace their aging mainframe computers with an object-based system, but this technology had never been used on such a large scale. In contrast, two-thirds of Capital One’s competitors outsourced their IT functions. Within 5 years the company had the world’s largest Oracle database with 23 terabytes of data – winning them the Gartner Group’s Excellence in Technology Award.
Data warehousing is a difficult system and has to have the capability deliver quality data. An operational database is one which is used by organizations to run its day to day database activities. They are designed to handle rapid transaction processes with systematically updates. Velocity is important to operational databases. They are most commonly operated by office staff, and are on the order of megabytes of data to gigabytes. Database consistency checks and constraints are rigidly enforced. They contain the latest technology necessary to operate organizational functions.
The main goal of EFT is for couples to create a secure bond between partners by choreographing new emotional experiences. The three stages of EFT guide the therapist to ensure the couple identifies and processes negative interaction patterns and the underlying emotions caused by these patterns. A secure therapeutic alliance is crucial between the EFT therapist and couple in order to safely complete all stages of therapy. Trust is an important factor that the couple needs in order to take risks and share primary emotions and attachment needs (Dalgleish et al., 2015). Cycle de-escalation, changing interaction patterns, and consolidation and integration are the three stages of EFT used to direct the couple towards a more

The cloud storage services are important as it provides a lot of benefits to the healthcare industry. The healthcare data is often doubling each and every year and consequently this means that the industry has to invest in hardware equipment tweak databases as well as servers that are required to store large amounts of data (Blobel, 19). It is imperative to understand that with a properly implemented a cloud storage system, and hospitals can be able to establish a network that can process tasks quickly with...
The Open Systems Interconnection (OSI) reference model is essential to the world of computer networking. The model was created in 1977 by the International Standards Committee, in response to a difficulty that was facing computer networkers at the time (Shelly, Cashman, and Serwatka 142). In order to understand the difficulty, one must first realize that computer networks consist of computer hardware, the software that is to be used in conjunction with this hardware, and the medium (such as wiring or cabling) that will interconnect the computing devices that are in the network. The computer networker’s job is to determine which hardware, software, and medium types will create the network that will best suit his client’s needs. Then, the networker must combine these elements into a functional system of interconnected computers (Fortino and Villeneuve 112). It was in attempting this latter task that the computer networker of the late 1970s often found himself in a pickle. The problem was that each vendor of computing equipment had developed his own unique set of products; products that were incompatible with the products of other vendors. This incompatibility made it very difficult for a computer networker to combine the various network components into an operational computer network (Stamper 27).
The reason for this rapid adoption is Linux’s unique ability to provide powerful functionality, security, compatibility, customization at a more cost-effective price than proprietary vendors. In its inception, there were many perceived concerns to utilizing Linux in a corporate infrastructure.
Enterprise Resource Planning (ERP) -. Abstract ERP systems are meant to help companies and businesses operate more efficiently when they are not. The main goal for a company is to choose a vendor that will give them the safest and easiest way to operate efficiently and achieve their business goals. What is an ERP?
...the cost effective development, it no need to be apply or tested in any possible operating system or configuration because this application itself was developed for a single operating system. Besides, the user can access the application everywhere as long as they have the connection to internet and PC. Web based system also is easy to customize because another user will easy to update the interface that can attract people and can customize the presentation of information to another group of user.
So with the much help from SAP ERP system, we have NRG-C bars in the market for sale. So it’s safe to say SAP if properly installed, implemented and right data integrated can ease its system users in their day to day business process and also help them in taking strategic business decision.
People travel miles in search of their true passion; some find them early in their life and I consider myself lucky enough to be one among them. I found my true calling at the age of 12 on a field trip to a milk factory. It seemed like the Disneyland of science with huge machineries, conveyer belts running all around, and instruments working about in their own rhythm with sheer intricacies and perfection. As a kid, I was eager to understand the mechanics behind this magical rhythm. The desire of gaining in-depth knowledge about Control System and Automation eventually led me to choose Electronics and Instrumentation Engineering as my undergraduate study.
...ms, your choices are Windows, Mac OS X and Linux. These three operating systems are viable choices for an organization. While one OS may do something better than another OS, they all have their pluses and minuses. Non-technical people may want to use Windows or Mac OS X, while people with a technical background prefer Linux. In fact, in many organizations, there won't be just one operating system in use. This may as well be the case with your organization. Web designers utilizing Adobe's Flash software to create animations will not want a Linux computer; programmers developing Windows software will not want a Mac. And, the people in charge of the network may recommend Linux over Windows Server. Fortunately, each of these operating systems can work with each other. All of them use the TCP/IP protocol, so networking different platforms together should be easy.
