Fundamentals of Volume Activation

Volume Activation is a set of activation methods applicable to systems under the Volume Licensing program or using Volume Licensing media obtained thru MSPP/MAPS/MSDN. Activation is required and Windows Activation Technology from Microsoft will make it simple to manage you organization's activation.

This video will get you started understanding Volume Activation by covering the fundaments of Volume Activation including:

• What is Activation?
• How do I Activate?
• What's new in Activation?
• Getting Started

ONE Oracle News for Midsize Organizations - Issue 04

Midsize companies have their size and agility on their side. To make the most of your agility advantage against larger competitors, streamlining your processes is one of the best steps you can take. Why? Because it will help you improve flexibility, accelerate responsiveness, boost efficiencies, lower costs and, ultimately, increase competitiveness. In this issue, we're taking a closer look at how cost control goes hand-in-hand with process flexibility. Your IT infrastructure can help, with integrated, automated processes that enable your staff to get things done faster.

Memory Sizing Guidance for Windows 7

This paper describes an approach that Information Technology (IT) professionals and system builders can use to determine how much memory is required to successfully run a set of programs. It explores how the choices in machine architecture, hardware devices, driver version, and memory configuration affect the amount of memory that is available to users' programs. By following the guidelines in this paper, one can determine the appropriate amount of memory to configure for anticipated customer workloads. This information applies to the Windows 7 operating system.

Firmware Corruption of Memory During Sleep Transitions

This paper provides information for system manufacturers and firmware developers about firmware corruption of memory during sleep transitions. During Windows 7 development, multiple Windows-based platforms have encountered memory corruption in the lowest 1 MB of physical memory after resuming from sleep. This paper describes the potential root causes of the memory corruption, diagnostic events in Windows 7 that can identify the corruption, and steps to resolve the problem on affected platforms.

Leveraging Dell EMC CX4 with Enterprise Flash Drives for Oracle® Database Deployments

This white paper examines the performance considerations of placing Oracle Databases on enterprise flash drives versus conventional hard disk drives, as well as discusses the best practices for placing partial database contain-ers on flash drives.

Articulating the Value Proposition of HPMQ - Why Buy HP Memory?

In order to bring HP memory products to market, they must be tested and conform to very stringent requirements in the HPMQ process to ensure they are reliable, meet customer requirements, and satisfy all of HP quality standards and measurements. The memory qualification process assures the customer that continuous improvements occur in the current and future products and processes. These continuous improvement actions benefit the Memory supplier, HP, and more importantly, HP customers. HP also uses an internal certification process called HPMQ. This paper is intended to provide a detailed description of the quality processes and methods that HP memory products are qualified under, to comply with the HP Memory Qualification (HPMQ) standards prior to the approval process.

Advances in Memory Management for Windows

This paper provides information about enhancements in memory management for Windows Vista and Windows Server 2008. It describes the changes that Microsoft has implemented internally in the operating system and provides guidelines for application developers, driver writers, and hardware vendors to take advantage of these advances. Microsoft has implemented major enhancements in memory management for Windows Vista and Windows Server 2008.

The Price of Safety: Evaluating IOMMU Performance

IOMMUs, IO Memory Management Units, are hardware devices that translate device DMA addresses to machine addresses. An isolation capable IOMMU restricts a device so that it can only access parts of memory it has been explicitly granted access to. Isolation capable IOMMUs perform a valuable system service by preventing rogue devices from performing errant or malicious DMAs, thereby substantially increasing the system's reliability and availability. Without an IOMMU a peripheral device could be programmed to overwrite any part of the system's memory. Operating systems utilize IOMMUs to isolate device drivers; hypervisors utilize IOMMUs to grant secure direct hardware access to virtual machines.

Understanding the Effects of Wrong-Path Memory References on Processor Performance

High-performance out-of-order processors spend a significant portion of their execution time on the incorrect program path even though they employ aggressive branch pre-diction algorithms. Although memory references generated on the wrong path do not change the architectural state of the processor, they can affect the arrangement of data in the memory hierarchy. This paper examines the effects of wrong-path memory references on processor performance. It is shown that these references significantly affect the IPC (Instructions Per Cycle) performance of a processor.

Efficient Runahead Execution: Power-Efficient Memory Latency Tolerance

Runahead execution improves memory latency tolerance without significantly increasing processor complexity. Unfortunately, a runahead execution processor executes significantly more instructions than a conventional processor, sometimes without providing any performance benefit, which makes it inefficient. This paper identifies the causes of inefficiency in runahead execution and proposes simple -yet effective-techniques to make a runahead processor more efficient, thereby reducing its energy consumption. The proposed efficiency techniques reduce the extra instructions executed in a runahead processor from 26.5% to 6.2% without significantly affecting the 22%performance improvement provided by runahead execution.
