IntroductIon

As iT executives look for ways to reshape service delivery to be more competitive, they continu-ally look to cut costs and operate within increasingly tight budgets. One big-ticket item is often the high cost of supporting Oracle database workloads, especially since database services are traditionally deployed on RiSc/ uniX systems, such as HP-uX on itanium, Oracle Solaris on SPARc, or iBM AiX on POWeR Systems. While these platforms have historically been the best options for achieving enterprise-level scalability, performance, and availability, the high cost of deploying and maintaining these systems is driving iT managers to seek more modern alterna-tives that offer equal or higher performance at a dramatic cost savings, with support for industry standards.

Moving Oracle databases to a Red Hat® enterprise Linux® and HP ProLiant platform brings enterprise-class advantages along with a persuasive financial incentive to migrate. Running the Oracle database on this industry-standard infrastructure can significantly lower your database application delivery costs. in addition, a Red Hat enterprise Linux and HP ProLiant platform brings the agility needed to extend service delivery into the cloud. A Red Hat and HP solution is the optimal next step for deploying your mission-critical Oracle database applications.

iT executives are choosing Red Hat enterprise Linux and industry-standard intel or AMd proces-sor-based systems because of the remarkable potential for savings in both capital and operat-ing expenditures (CAPEX and OPEX). Specifically they are turning to Red Hat and HP because of their industry expertise and acumen as standards-based platform providers.

Moving Oracle databases to Red Hat enterprise Linux and HP ProLiant systems allows compa-nies to migrate with confidence. For more than 12 years, Red Hat and HP have worked together to help enterprises and organizations transition Oracle workloads while minimizing risk. Many companies that depend on Oracle database applications to power their businesses have suc-cessfully made the transition from RiSc/uniX, including nYSe euronext (the global parent of the new York Stock exchange), Lufthansa cargo Ag, and Wells fargo, among others (see sidebars).

A successful migration builds on the success of companies like these that have made the change, leveraging their experience, best practices, and lessons learned. Red Hat provides migration planning guides that represent many successful transitions, detailing field-tested steps for moving applications from existing RiSc/uniX systems to a Red Hat enterprise Linux and HP platform. HP Migration competency centers around the globe are dedicated to the task of moving your data and applications to an HP converged infrastructure—one that coalesces datacenter assets into a common, centrally managed, and cost-effective resource pool. experienced Red Hat migration consultants can assist with planning and implementing the change, optimizing performance and security for your largest mission-critical database workloads.

Migrating from traditional uniX systems to Red Hat enterprise Linux leverages your invest-ment in personnel and their accumulated expertise. Many of the same tools used to manage HP-uX, Oracle Solaris, and AiX systems are similar to tools in Red Hat enterprise Linux. if you are migrating Oracle applications from these uniX systems, these similarities make Red Hat enterprise Linux the logical choice over Microsoft Windows Server because your staff can be productive quickly with a minimal amount of retraining. Red Hat offers a broad course curricu-lum, including the Red Hat Certified Engineer qualification, which is the de facto industry stan-dard for Linux administration. in addition, Red Hat offers a system administration course that specifically targets administrators coming from the Oracle Solaris environment.

planning a migration

Any iT transition requires diligent planning to minimize downtime and speed the process. Red Hat migration planning guides outline common implementation standards, available train-ing, and best practices. These guides highlight the five basic steps to migrate Oracle workloads from existing uniX platforms:

1. Analyze the current infrastructure supporting your Oracle database, identifying equivalent capabilities available in the Red Hat enterprise Linux and HP ecosystem. for example, identify database options, internally developed applications, third-party tools, compilers, program-ming interfaces, system management utilities, etc.

2. Confirm that specific versions of Oracle database options and third-party infrastructure applications that you are using are certified on Red Hat Enterprise Linux and identify any particular application dependencies. With more than 5,000 applications certified on Red Hat enterprise Linux, it’s likely that the components in your software stack are already certified. Oracle widely supports its database products and options on releases of Red Hat enterprise Linux.

3. Measure organizational readiness and overall migration risk. This step looks at additional technical and business details such as server sizing, service-level agreements, server refresh cycles, staffing readiness, training needs, and IT processes and practices. HP Enterprise and Technology Services offers experienced migration consultants who can help to size servers in the solution.

4. develop a strategic migration plan that includes a detailed roadmap, project team, timeline of migration activities, and a cost estimate. for Oracle database workloads, data export and import are key migration steps that can drive the overall timeline.

5. implement the migration plan and leverage implementation support strategies. experienced migration veterans from Red Hat and HP can apply best practices to save time, minimize risk, and reduce cost. Red Hat consulting also offers a wide variety of workshops, training, and ser-vice offerings.

What you can expect

Many companies have completed migrations from RiSc/uniX systems to Red Hat enterprise Linux and have experienced a reduction in cAPeX and OPeX. iT executives can often justify the associated costs of a migration based on estimated TcO savings, achieving a quick return on investment.

Figure 1 compares three-year TCO calculations for migrating an Oracle application stack from UNIX servers (specifically from Oracle Solaris servers) to an HP ProLiant DL980 G7 system running Red Hat enterprise Linux.1 under this scenario, an HP ProLiant system and Red Hat Enterprise Linux achieve an overall savings of 81% over three years, reducing overall costs by about $8.5 million. Software costs alone (for the database and operating system software) drop from $3.57M to $1.15M, while hardware costs fall from $2.7M to only $112K. Power and facilities-related costs also decrease dramatically.

Key factors that contribute to TCO savings include lower software maintenance costs as well as operational efficiencies. With Red Hat Enterprise Linux, you pay for an annual software subscrip-tion instead of a large up-front expense for software licenses. According to a recent idc study, standardizing on Red Hat enterprise Linux allowed organizations to recover subscription costs quickly “through more efficient operations, higher ratios of servers and users per administra-tor, and a significantly lower annual downtime cost.” The study found that Red Hat Enterprise Linux adopters averaged 174 systems and 422 users per administrator, incurred only $18,960 in annual IT costs per 100 users, and recouped subscription costs in as little as seven months.2 Since a Red Hat subscription gives you access to new releases, feature enhancements, proactive security updates, and additional hardware/software support, it adds value over the full lifetime of the deployment.

Red Hat and HP’s world-class engineering and support organizations actively collaborate to innovate solutions and resolve problems, applying their technology expertise to your day-to-day iT operations and long-term initiatives for consolidation, virtualization, and cloud computing. Global 24x7 support is available from both companies to keep your strategic enterprise applica-tions up and running.

The value of open source

As the world’s leading Linux provider, Red Hat believes that open source nurtures innovation, promotes standards, and encourages interoperability, ultimately to your benefit. The open source community and Red Hat subscribers are valuable assets in identifying and solving the next generation of computing challenges.

Red Hat’s overall development approach is simple but effective: the company’s engineers actively develop and contribute open source code. According to the Linux Foundation, for five kernel releases ending in August 2010, Red Hat boasts a “commanding” lead over any other vendor that contributed to the Linux kernel, contributing over twice the number of changes as Attachmate novell developers and six times that of Oracle Linux developers.3

To build a major release, Red Hat takes a snapshot in time and freezes development. Once this happens, engineering integrates and stabilizes all packages and tools, testing and tuning the release in conjunction with input from major hardware and software vendors such as HP and Oracle. After announcement, every release goes into a maintenance cycle where subscribers and the community provide feedback, new features are introduced, bugs are fixed, etc., in a fully supported lifespan that extends up to ten years. during this time, Red Hat engineers continue to collaborate with the open source community, subscribers, and strategic hardware and software partners to add and test new capabilities that provide robust availability, security, and scalabil-ity, as well as features that serve the community at large.

enterprIse-class benefIts

Together, Red Hat enterprise Linux and HP ProLiant servers form an unmatched enterprise-class platform for Oracle applications—one that can evolve with your business and take advan-tage of ongoing technology innovations. By moving Oracle workloads to this platform, you can standardize on an infrastructure that meets application demands today and into the future, while achieving the benefits of enterprise scalability, availability, security, manageability, and agility at a lower cost.

performance and scalability

Since Oracle applications are key to driving business and service delivery, application response time is critical to your ability to compete. if your supporting Oracle database infrastructure fails to scale in sync with application demand, response times become slow and inconsistent, which can impact your bottom line. fortunately, Red Hat enterprise Linux and HP ProLiant servers cre-ate an exceptionally scalable and responsive platform for Oracle workloads.

HP ProLiant servers are engineered to scale compute, memory, and i/O resources to address growth over time. For example, the HP ProLiant DL980 G7, with support for eight sockets, 64 cores, 2TB of memory, and 16 I/O slots, features a revolutionary new HP PREMA system archi-tecture. The HP PREMA system architecture is the foundation of HP scale-up x86 server plat-forms and features smart processor caching that takes advantage of intel® Xeon® processors and their Quick Path interconnect technology to improve cPu utilization, increase through-put, and accelerate performance. Complementing the HP ProLiant DL980 G7 server, Red Hat Enterprise Linux 6 (the latest release) is also engineered for massive scalability, supporting up to 4,096 CPUs and 64TB of memory. Whether your goal is to migrate a single, data-intensive workload or to consolidate and virtualize a number of software infrastructure elements, you can configure an HP ProLiant and Red Hat Enterprise Linux platform that scales effectively to sup-port your Oracle application stack.

Figure 2 shows how Oracle OLTP performance scales as the number of Intel processor cores increases and how the number of transactions per minute (TPM) scales with each successive processor generation. The rate of scale becomes more linear with each new intel processor series, demonstrating that processor advances (such as those available in HP ProLiant plat-forms) can continue to scale your OLTP performance more efficiently.

There are a number of industry benchmarks that illustrate the excellent scalability of Red Hat enterprise Linux for both decision support system (dSS) and online transactional processing (OLTP) workloads:

• Two out of the top four TPC-H results for 100GB databases, reported in February and May 2011, were delivered running Red Hat Enterprise Linux 6, demonstrating excellent perfor-mance for DSS workloads. In the 300 GB TPC-H benchmark, Red Hat Enterprise Linux 6 placed third in May 2011.5

• Red Hat Enterprise Linux was the first operating system on Intel processors to exceed 1M TPM (reaching 1.2M TPM in August 2008 using Intel Xeon X7460 processors) for the TPC-C bench-mark that measures OLTP performance.6

Red Hat conducted testing to compare performance of OLTP workloads under Oracle database Release 11g on Microsoft Windows Server 2008 versus Red Hat Enterprise Linux. By swapping out the operating system in the test scenario, Red Hat enterprise Linux demonstrated a perfor-mance gain of 14-20% over a similarly configured Windows platform.7

Perhaps even more convincing is the proven success of companies that have migrated Oracle workloads and achieved remarkable performance and scalability improvements. Western Power, a government-owned Australian electricity company, migrated from uniX to Red Hat enterprise Linux and experienced a performance gain of 500% for a known Oracle database workload.8

virtualization that scales

To support server virtualization and consolidation, HP ProLiant servers are available in a broad spectrum of configurations with support for many multiple-core CPUs, large memories, I/O expansion, and storage options. With the built-in virtualization capabilities of Red Hat enterprise Linux, HP ProLiant servers (like the eight-processor HP ProLiant DL980 G7) are ideal for con-solidating Oracle database workloads. When consolidating applications on a single server, it’s critical that each application gets the system resources it needs. Red Hat Enterprise Linux 6 features control groups, or “cgroups,” that allow an administrator to allocate and control spe-cific resources that any one application, or set of applications, can consume. Thus, it’s easy to run the Oracle database in one virtual machine on a Red Hat enterprise Linux guest with well-defined CPU and memory limits while running application servers and web servers as other guests with their own set of compute, memory, and networking resources.

in such a virtualized environment, guests must impose low overhead so that applications can scale and provide high performance levels. When testing virtualized workloads on Red Hat enterprise Linux (figure 3), engineers saw that OLTP workloads scaled nearly linearly in all con-figurations tested with low overhead when virtualizing multiple hosts and multiple virtual CPUs. As Figure 3 shows, multiple virtual guests on a single host demonstrated about 93% of bare metal performance — there was no noticeable performance difference between scaled-up and scaled-out virtual machines. The testing indicates that you can choose to virtualize Oracle OLTP workloads on Red Hat Enterprise Linux and still experience highly efficient scaling.

Recent SPECvirt_sc2010 benchmark results also demonstrated excellent scalability based on the HP ProLiant DL980 G7 system and Red Hat Enterprise Linux. The SPECvirt_sc2010 benchmark measures end-to-end performance of virtualization system components, including hardware, the virtualization platform, the virtualized guest operating system, and application software. Results for the eight-processor HP ProLiant DL980 G7 and Red Hat Enterprise Linux 6 were 7,424@456VMs or 76 tiles (a tile is a grouping of 6 different VMs). Compared to the results for the four-processor HP ProLiant DL580 G7, which exhibited results of 3,894@240VMs (40 tiles), the HP ProLiant DL980 G7 system showed close to linear scalability for the virtualization workload tested as the number of processors increased.9

Availability

Red Hat enterprise Linux is the foundation for running strategic Oracle applications that repre-sent millions of dollars in financial trades, transactions, and business decisions each day. When Red Hat enterprise Linux is combined with the resiliency of HP ProLiant servers, you can deploy a dependable solution for demanding mission-critical database applications like many other companies have done. HP ProLiant systems boast reliability features that bring synergy to a Red Hat deployment. for example, the HP PReMA architecture incorporates a redundant sys-tem fabric that leverages reliability advancements in recent-generation intel Xeon processors. As a result, this architecture supports high-throughput interconnects, low data-error rates, and dynamic traffic routing to reduce downtime.

Red Hat Enterprise Linux 6 also takes advantage of advanced RAS features in the latest Intel Xeon Series processors, supporting cPu hot swap, hot-add, and off-lining to minimize unplanned downtime. Proactive self-healing capabilities in the operating system automatically diagnose and isolate defective cPus or memory components, enabling quick recovery from certain hard-ware and application faults.

Security

Since the Red Hat Enterprise Linux distribution is open source, it profits from an extensive developer community and numerous security experts who contribute and review the source code. The open source model yields a strong code base while supporting innovation of new security features. The model has produced security enhancements such as access control fea-tures, cryptographic libraries, and trusted utilities for host, network, and application security. Today Red Hat enterprise Linux provides comprehensive security tools and a complete security stack, from network firewall control to SELinux mechanisms for access control enforcement.

for business-critical Oracle applications, Red Hat’s subscription model is an important element in maintaining the security of the operating environment. Red Hat proactively releases peri-odic software updates and patches to address bugs, provide enhancements, and improve secu-rity mechanisms. In addition, Red Hat engineering — specifically its global Security Response Team — is dedicated to investigating reported security vulnerabilities, quickly releasing security fixes for all supported Red Hat products and services if an exposure is discovered.

A testimonial to the robust security of Red Hat enterprise Linux is its wide deployment in data-centers, especially in financial institutions and stock exchanges. NYSE Euronext, which operates exchanges in the u.S. and europe, selected Red Hat enterprise Linux to run its mission-critical global trading platforms. Processing one-third of the world’s equities trading and handling bil-lions of messages each day, Red Hat enterprise Linux and HP platforms at nYSe euronext are tasked with delivering the highest degree of security, reliability, and performance at all times.

manageability

Both Red Hat and HP offer comprehensive tools to help you manage your datacenter effectively and efficiently. Red Hat Network Satellite is a enterprise-wide management framework that automates administrative tasks, including patching and updates, making your datacenter more secure, manageable, and consistent. Red Hat network Satellite leverages built-in RPM package management technology—well known by administrators in the large installed base of Red Hat enterprise Linux subscribers—to track and resolve software package dependencies for all data-center servers. for Oracle database installations, quickly resolving software dependencies helps to expedite time-to-deployment. Once database applications are installed, tuned, and running, Red Hat Network Satellite allows careful certification, tracking, and sign-off of any additional software changes, which helps to increase uptime for your production environment.

complementing Red Hat network Satellite, HP insight control for Linux is a comprehensive man-agement platform for HP ProLiant servers that host Red Hat enterprise Linux. insight control is used to perform administrative tasks, including server discovery, imaging, provisioning, deploy-ment, remote performance monitoring, virtualization, and power management. The toolset inte-grates easily with the HP System insight Manager (SiM) ecosystem, allowing you to proactively manage servers throughout your datacenter, optimize utilization, and effectively plan datacen-ter capacity to meet growing application demands.

Agility

As iT executives ponder their future iT roadmaps, a common thread is emerging: how to lower the cost of delivering business applications while evolving the next generation of enterprise iT services. As Oracle database services transition to a cloud model, it is clear that organizations that engender agile computing solutions today will be well-positioned to embrace change. Why? distributing application services in the cloud means that there will be a greater number and variety of consumption end-points, which means that IT flexibility, portability, and scalability will be key. in addition, the same enterprise characteristics needed to support your mission-critical Oracle applications today—performance, reliability, manageability, and security—will drive the ubiquity of cloud services.

Red Hat and HP are actively working together to help enterprises like yours reduce the cost of supporting Oracle database applications and at the same time design infrastructures that can readily adapt to cloud service delivery models. Red Hat prides itself on being more than just an open source operating system developer, supplying a full portfolio of software technologies that comprise a modern computing platform: middleware, virtualization, Platform-as-a-Service (PaaS), and infrastructure-as-a-Service (iaaS) tools. And HP is certainly more than just a hard-ware vendor — it is recognized as a trusted business partner that furnishes robust enterprise computing solutions, reference architecture examples, consulting services, and unsurpassed customer support. By combining Red Hat software and the HP converged infrastructure, you can build an iT environment ready to take advantage of advances in technology.
