]]> around Oracle in virtualized environments. One of the best kept secrets is just how come up Oracle performs on VMware ESX. This didn’t come about by accident – there are a number of features and performance optimizations in the VMware ESX server architecture specifically for databases. In this blog. I'll walk through the top ten most important features for getting the best database performance. Here are a few of the performance highlights: We’ve continued to invest a great deal of work towards optimizing Oracle performance on VMware because it’s already one of the most commonly virtualized applications. The imminent ESX 3.5 release is our best database platform to date with several new advanced optimizations. In this blog article we’d like to explain the unique and demanding nature of database applications such as Oracle produces and show the performance capabilities of ESX Server on this type of workload. The performance of a virtualized system should first be quantified in terms of latency and throughput and then in terms of how efficiently resources are being used. For example if a physical system is delivering 10000 transactions per minute at 500ms latency per transaction then a virtualized system that is performing at 100% of native should give the same aim of throughput with acceptable latency characteristics. Secondary should be a metric of resource usage which is a decide of how many additional physical resources were used to achieve the same aim of performance. It’s sometimes overly easy to focus primarily on the CPU resource when in reality memory and I/O are much more expensive resources to furnish. This is becoming especially important going forward as multicore CPUs continue to lower the cost per processor core while memory cost remains at a premium. More important for Oracle is the ability to scale up by taking favor of multi-core CPUs large memories and the I/O throughput through the hypervisor to give the large number of plough spindles in the backend storage arrays. There isn’t one quick hit to make databases work well for a wide range of real-world applications – good performance is something that is earned from the long term discipline of focusing the lessons learned from many customer-oriented real-world database workloads and applying those lessons across the architecture of the hypervisor. Since the hypervisor logically resides between the database in the guest virtual.

The goal of Adaptive Infrastructure is to use HP's various software hardware and function offerings to look at the data center in a more holistic way and give customers a hit integrated infrastructure that can be changed to cater the needs of a company. BobB writes "Oracle is going after its piece of the hot virtualization merchandise by introducing an open obtain Xen-based hypervisor to compete against those from Novell. Red Hat and VMware. Oracle VM unveiled Monday at the Oracle OpenWorld convention in San Francisco enables virtualization on Oracle and non-Oracle software applications and on the Linux and Windows OSs. It also operates on industry-standard x86- and x86-64-based servers. Oracle claims it offers virtualization at a displace cost than competitors can." Oracle announced Oracle VM available for free download since tomorrow. November 14. 2007 at: http://www oracle com/virtualization. Oracle VM is a server virtualization software solution based on Xen(TM) hypervisor technology. Oracle VM installs directly on server hardware and does not demand a entertain operating system so we need to lay it on forge from the adjoin. Oracle VM and provides better performance than products from other vendors and it’s going to become the best friend of Oracle Enterprise Linux for faster deployments. By offering Oracle VM give at displace prices. Oracle again is pursuing a strategy it revealed measure year when it offered less-expensive give for the Red Hat Enterprise Linux operating system than Red Hat does. By offering a Xen-based hypervisor just as Red Hat and Novell do. Oracle could increase its competitive compel. Oracle VM provisions virtual servers manages virtual environments and moves applications from one server to another while the program remains running. “With Oracle VM users act doing what they’re doing whether they are running a database or running an application they don’t see any dress at all. Their job just moves from one machine to another,” said Chuck Rozwat executive vice president of product development for Oracle during a demonstration of Oracle VM at OpenWorld. Companies like Oracle are introducing virtualization hypervisors to act some control away from the operating system over software applications in a server says Gordon Haff principal analyst with investigate firm Illuminata. But Oracle based in Redwood Shores. Calif. also wants to muscle in on the market overlap of the leading hypervisor vendor. VMware in nearby Palo Alto. Interestingly enough this displace be strategy is also reflected in. (Sorry. I'm working this out in my head just now.)Back to Oracle VM. Virtualization is outside of my specific scope of interest but I open it interesting (especially after Oracle's announcement) that upon my arrival at Oracle OpenWorld the plan Builder had automatically scheduled me to be an executive session.. hosted by VMware. Unfortunately. I spent much of the meeting about the application of VMware - or for that matter any vendor's virtualization technology - to my specific widget.

I also accept that the is the for the product formerly labeled as the command intend operating system. Historically and general intend operating system served 2 important roles:1) provide drivers that consider the hardware and make the hardware resources and network available to the software applications and2) provide system services (register system schedule libraries) to the applications such that they can execute their label in a predictable and efficient manner. The 1st role above is now being relinquished to the hypervisor. Srinivas argues that the second role should be accomplished using JeOS. However the actual configuration and components of JeOS by definition should vary considerably from application to application as each application needs different resources to operate efficiently. So can JeOS be a product category sold in the same manner that general purpose operating systems were historically sold? As a “one coat fits all” collection of general purpose utilities and libraries? Well let's investigate how the general purpose operating system is sold and cause if the same come can be applied to the new JeOS category. As accent. I ran product marketing at Red Hat from early 1999 until midyear 2000 and I was the first enterprise sales leader for Red Hat. I was Vice President of North America sales for Red Hat from April 2001 until January 2005. During that measure we were very successful in growing sales of Red Hat Enterprise Linux by mimicking the Microsoft server OS product come. Red Hat provided a shelter release of operating system technology with a very broad set of utilities and libraries included. This release was accompanied by a commitment to five years (now seven. I think) of maintenance and regular updates for new hardware drivers bug fixes and security fixes. It was also accompanied by a restriction that released Red Hat from its give obligation if the customer made any changes to the components that defined the operating system. Without this restriction. Red Hat could not possibly afford the engineering and customer function expense associated with supporting every customer's preference for utilities program libraries and system services. Further the operating system itself required so many components to support so many components to support so many more components that changing any one of them often left the operating system in an unstable and unmaintainable express. This problem is often referred to by system administrators as “dependency hell.” But since the operating system was often distributed by the hardware server providers as the mechanism to connect an application to the hardware it was unavoidable that this restrictive copy be strictly enforced to enable the industry to get on with shipping hardware that could be used by applications. The restriction did not prevent customers from making changes to the operating system and subsequently seeking give from Red Hat. They simply absorbed the risk and much of the costs associated with the changes. If Red Hat turned them away because their changes did not change to Red Hat's definition of the operating system they soldiered on and did their beat to alter the operating system work for their applications. It never really occurred to them or to Red Hat that it might be a good idea to change the underlying packaging technology of the operating system to make it easy for the customer to change the things that did not work for them. Such a solution was unthinkable because it would get the server hardware vendors with an undefined account of materials. The server business is a high volume business that requires some level of standardization among the components to bring home the bacon determine competitiveness through economies of scale. Changing the operating system for every server depending on the application workload it is intended to answer does not make any economic sense. Now that the hypervisor is going to change state the new operating system that supports the hardware should the JeOS that supports any given application be a product with the same architecture as the legacy general purpose operating system? i e a collection of components defined by the operating system vendor as supportable and maintainable? so desire as you don't change the assumptions the operating system vendor made when the collection was assembled and tested and released? so long as you don't dress any of the components because that makes the collection unsupportable? How is that possible when by definition the collection of components that the application vendor is going to use is going to change depending on the needs of the application? evaluate about it. JeOS cannot be an operating system product. JeOS must be a packaging architecture (and perhaps a testing architecture as come up). JeOS must say the challenge “What does the application need?” based upon the application it is presented. JeOS must then assemble around the application the components that represent the smallest possible closed circle set of components to entertain the application. It must then affirm that this “set” is reasonable based upon the testing scenario for the application (hence my comment above about a testing architecture). It must subsequently enable the integration of the various maintenance streams for the components with the server set to provide an elegant lifecycle experience for the application vendor and its customers. In this scenario the application provider takes on a much broader responsibility for the support of the operating system and at the surface level this can be very scary. On advance inspection however the application vendor or their customer was already assuming this charge in the legacy copy where the general intend OS was modified on premise to give the application. With a contend through dependency hell followed by an ongoing war with the maintenance stream from the OS vendor (which was often ignored because it could not be reconciled with the needs of the application). With JeOS as a packaging architecture (instead of a “one coat fits all” product) the component set that must be maintained is much smaller and much more intimately related to the application. By definition the application vendor ordain be in a good position to determine and end problems given this tight definition and technical affinity with the application. No doubt they will comfort be the technical expertise of a vendor with deep operating system skills as a play but the product they change from that vendor ordain look very different than the product historically labeled as a command intend operating system. It will be a packaging architecture with a system software compose platform and a create/test methodology. Anything else defies logic in a world where every server has a hypervisor and every application arrives as a with JeOS.

You may comprehend these bundles called "applicationblades". "software blades" or "virtual appliances". Whatever you call them they represent a new way IHVs will deliver OSV and ISVsolutions. And this scenario doesn't apply to just VMWare based on XenSource'sannouncement of support for XenSource may not be far behind VMWare(something to watch for in the near future). No doubt Microsoft will use theirleverage with the IHV to do the same with Viridian when ready. When virtualization first appeared on the scene many people predicted thedemise of both the IHV and Operating System Vendor (OSV) market. But as we cansee now there is no be to conclude sorry for these vendors. Virtualization hasbeen a boon for OSVs. The ease at which administrators can cause new virtualmachines only increases the number of operating system licenses -- multiplefold. And while virtualization has sparked a wave of consolidation of serverhardware the IHVs have responded by building beefier virtualization-readymachines with greater acquire margins. Now because of ROM-based hypervisors,IHVs have enabled a platform to change multiple (acquire margin rich) solutionsper HW platform. Even better using this copy the customer can use the IHVas an image repository by sending custom VHD images used for server populationbefore delivery. This opens a whole new world of services the IHV can furnish tothe customer.. everything from data and visualise warehousing to image and patchmanagement to disaster recovery. And let's not forget about desktops. Although not on anyIHV radar at the moment you have to accept ROM-based hypervisor boot ofdesktops not far behind. Imagine a world where your desktop boots a hypervisor,loads a small network stack and runs a small application that uses the network(or internet) to show to the end-user a list of VHDs to boot as a guest OS.
