Top 5 Performance Tips for Tuning a Data Warehouse on Grid 2005-12-06 01:01:57

An emerging trend in the computing industry is the deployment of data warehouse systems on a "Grid" of industry standard commodity server running the Linux operating system. These low cost systems enable companies to scale their data warehouse to multiple terabytes while still meeting their IT budgets requirements. However, in order for a Linux Grid configuration to be successful it must achieve the level of performance and reliability required for a data warehousing system. This paper will help system engineers create reliable and performing Linux RAC systems for data warehouse applications.

Managing Oracle Collaboration Suite With Enterprise Manager Grid Control 10g Release 2 2006-07-25 01:08:30 Oracle

Oracle Collaboration Suite provides capabilities - such as mail, calendar, web conferencing and content services - that are critical to the productivity of an organization. Users access Collaboration Suite services every day to communicate with colleagues, host remote meetings, and share information. Therefore, it is important that Collaboration Suite administrators have reliable, comprehensive tools to effectively manage the performance and availability of their Collaboration Suite deployments. Oracle Enterprise Manager provides the monitoring and administration capabilities administrators need to ensure the performance and availability of Collaboration Suite services meet customer expectations and service level goals. This paper outlines the management capabilities of Grid Control 10g Release 2 for Oracle Collaboration Suite 10gR1.

How to Automate Testing - without Aggravating Testers 2006-08-17 07:20:48 Mercury Interactive

This paper gives practical advice, based on the experiences and lessons learned by Michael Anthony of Iron Mountain, about how to integrate automation into testing processes - without alienating your testing team. Examine how to divide up the tasks and responsibilities, how to get training and assistance from vendors, how to integrate automation testing within product lines, and how to prove the benefits of automation not only to your team but to internal IT customers, application users, and management.

Enterprise Business Intelligence: Strategies and Technologies for Deploying BI on an Enterprise Scale 2007-01-24 01:00:28 Hyperion

Since its inception, Business Intelligence (BI) has promised to empower businesses by providing direct access to information they can use to make decisions, create more effective plans, and respond more quickly to problems and opportunities. Eager to reap the full benefits of business intelligence, many businesses now want to transform BI from a departmental to an enterprise-wide initiative.

QoS-Based Scheduling of Workflow Applications on Service Grids 2005-12-21 01:01:53

Over the last few years, Grid technologies have been enhanced towards a service-oriented paradigm that enables a new way of service provision based on utility computing models, which users consume based on their QoS (Quality of Service) requirements. In such "pay-per-use" service Grids, issues such as resource management and scheduling based on users' QoS constraints are yet to be addressed especially in the context of workflow management systems. In this paper, a QoS-based workflow management system and scheduling algorithm is proposed that minimizes execution cost workflow application while meeting timeframe for delivering results.

GRUBER: A Grid Resource Usage SLA Broker 2006-08-04 01:00:11 Springer Science+Business Media

Resource sharing within grid collaborations usually implies specific sharing mechanisms at participating sites. Challenging policy issues can arise in such scenarios that integrate participants and resources spanning multiple physical institutions. Resource owners may wish to grant to one or more Virtual Organizations (VOs) the right to use certain resources subject to local usage policies and service level agreements, and each VO may then wish to use those resources subject to its usage policies. This paper describes GRUBER, an architecture and toolkit for resource usage Service Level Agreement (SLA) specification and enforcement in a grid environment, and a series of experiments on a real grid, Grid3. The proposed mechanism allows resources at individual sites to be shared among multiple user communities.

Linpack HPL Performance on IBM eServer 326 and xSeries 336 Servers 2005-09-15 03:00:04 IBM

This paper examines the performance of the Linpack benchmark on IBM eServer 326 (e326) and IBM eServer xSeries 336 (x336) systems. The e326 is powered by AMD Opteron processors, and the x336 is powered by Intel Xeon processors. In this paper, system factors are considered that affect benchmark performance, such as processor and network performance, and the paper shows that it is not sensitive to memory performance. The paper also considers ways to tune the benchmark. In particular the paper examines what are good values for P, Q, N, and NB, and concludes that optimal values for NB must be determined through experimentation, although many values of NB can be eliminated through simple analysis.

A Comparison of Single-Core and Dual-Core Opteron Processor Performance for HPC 2005-09-15 03:00:04

Dual-core AMD Opteron processors represent the latest significant development in microprocessor technology. This paper, using the IBM eServer 326, examines the performance of dual-core Opteron processors. Dual-core Opteron processors perform very well on applications that are highly parallel and whose performance is limited by the processor core, that is to say, by the frequency of the processor clock.

Advanced Virtualization Capabilities of POWER5 Systems 2005-11-29 01:00:03 IBM

IBM POWER5 systems combine enhancements in the IBM PowerPC processor architecture with greatly enhanced firmware to significantly increase the virtualization capabilities of IBM POWER servers. The POWER hypervisor, the basis of the IBM Virtualization Engine technologies on POWER5 systems, delivers leading-edge mainframe virtualization technologies to the UNIX marketplace. The technology behind the virtualization capabilities that are available on the POWER5 servers, enabling customers to better utilize the industry-leading computing capacity of the POWER5 processor, is discussed in this paper.
