Oracle DB Certifications on Linux on System z• Oracle has been delivering database solutions on Linux on System z Servers since 2002• On March 30th, 2011 delivered Oracle 11g Release 2 (11.2.0.2) Database for Linux on IBM

System z Servers.• New features such as Real Application Testing and support for huge pages, make this an

interesting Linux on System z option.

• E-Business Suite on Oracle Database 11g Release 2 is supported as a mixed mode architecture (formerly " split tier architecture"). Database can run on Linux on z. EBS code runs on a different platform ( AIX, Linux on x86, etc.)

• Hyperion Finance EPM is supported on Linux on System z in a split tier architecture.

Why System z for Oracle

• High Availability Requirements

• Open Standards and Linux

• Disaster Recovery Requirements

• Customer Data on Mainframe

• Increased Performance Requirements

• Economics of Linux (IFL) Specialty Engines

• TCO versus Total Cost of Acquisition

• ‘Green’ Value from Mainframe

• zEnterprise servers can virtualize everything with up to 100% utilization rates

• zEnterprise is the only Heterogeneous platform in the industry

• System z has the highest security rating or classification for any commercial server

17

System z – Extreme VirtualisationBuild-in and Shared Everything Architecture

System z

• Provisioning of virtual servers in seconds

• High granularity of resource sharing (<1%)

• Upgrade of physical resources without taking the system down

• Scalability of up to 1000’s of virtual servers

• More with less: more virtual servers per core, sharing of physical resources

• Extensive life-cycle management

• HW-supported isolation, highly secure (EAL5 or EAL4+ certified)

Distributed platforms

• Limited virtual server scalability per core

• Scaling requires additional physical servers

• Operational complexity increases with growth of virtual server images

• VMware, Xen, Hyper-V focus on x86, no HW management across multiple platforms

Business Case For Oracle Consolidation

20

Linux on System z and Oracle Licensing

• An IFL is a specialty engine or Processor on a System z machine

• Oracle uses the term core for purposes of pricing

• From an Oracle licensing perspective an IFL = one core

• The zEnterprise has 4 or 6 core processors but an IFL represents one core

• The consolidation factor is a huge saving in licensing

Sizing is a very important action for consolidation !

21

When Is An Oracle Consolidation Paying Out?

• Real customer situation

• For an Installation of Oracle (RAC) starting with 2 servers‒ Server with 6 Cores - 2 X 6 = 12 Cores

‒ Oracle Enterprise Licenses

‒ RAC Feature

• Replacement with z114 - much cheaper and effective‒ Workload could be handled with 2 IFLs

• Price saving over 3 years:

‒ Almost one million Euro savings

- starting with 2 Server (RAC) installation

• Easy maintenance as cluster nodes can be stopped with minimum disruption

But does not include disk storage

• Storage and Network HA need to be included

• Could be more flexible infrastructure for provisioning, maintenance and failover operations

• Free resources are reserved in DR server (capacity on demand) to get the additional workload in case of a node failure/maintenance

Deploying RAC for High Availability

RAC – Real Application Cluster

• Active/Passive configuration

‒ One node processes work

‒ The other node waits for the first node to fail

‒ No extra CPU resources !

• Active/Active configuration

‒ All nodes process work

‒ If any node fails the cluster is re-mastered.

• Besides availability, RAC can be used for workload distribution

‒ All work does not have to go through all nodes

• Deploy

‒ In the same LPAR for test/dev applications

‒ Across LPARs for LPAR maintenance or software failures (most common implementation)

‒ Across CECs when taking entire systems down is a “common” occurrence

When Consolidating Oracle Database Servers• Understand your requirements (and cost implications)

‒ High Availability (how much money is at stake if your system is down x minutes/hours?)

‒ Disaster Recovery (what is your RTO by application/database?)

➔ Select architecture choices according to requirements

• Low utilization servers and mix of different peak times are best candidates‒ Selected databases with sustained high CPU utilization may not be good candidates

• Databases with high I/O stress will benefit from System z architecture

• Tune migrated database servers to the virtualized environment‒ Right size servers (memory, number of vCPUs, direct I/O)

‒ System z may behave differently compared to x86

• Monitor your system behavior‒ Typically performance behavior is not static

‒ Test before and after changes are applied

• Consider Capacity on Demand (CoD) for peak load times

Dundee City Council Delivers Value Through New Technologies

Business need:Like all UK local authorities, Dundee City Council needs to handle increasing demand for IT and eGovernment services, while also reducing costs in line with central government targets. When the lease on its server and storage hardware needed to be renewed, the Council saw an opportunity to enhance its capabilities and increase value for money.

Solution:Dundee worked with IBM to upgrade its mainframe environment with two powerful IBM System z10® servers, and introduced the IBM XIV® Storage System to replace a mixed storage environment. The new infrastructure runs a range of Linux applications and Oracle databases – supporting key systems such as social services 24x7.

"Running Linux on the System z platform is a cost-efficient approach, especially for software like Oracle, which is licensed on a per-processor basis.

We can run 60 virtual machines on just four System z processors – whereas an equivalent x86-based architecture might require several processors for each server! So the savings can be considerable ."

- Tim Simpson, IT Support Manager, Dundee City

Council

Benefits:• Improves performance by more than 50 percent, providing capacity for growth without

increasing IT costs. • Enables very rapid provisioning of virtualised server and storage resources, enabling the

IT team to respond more quickly to end users’ needs. • Provides excellent availability and disaster recovery capabilities: in the event of a

disaster at the main site, all systems can be restored at another location within 20 minutes.

• Reduces Oracle licensing costs, as numerous virtual Linux servers can run on each IFL processor.

Sparda Datenverarbeitung eG chooses IBM zEnterprise with SLES for System z

Watch and listen to• Bernd Bohne, Sparda-Datenverarbeitung e.G., Manager, Central Systems• Marie Wieck, IBM, General Manager, Application Integration Middleware• Steve Mills, IBM, Senior Vice President & Group Executive, Software & Systems

“Over the years, the mainframe transformed from traditional workloads, quite simple, to a universal platform for new workloads as well. And we see a lot of new applications that are coming to this platform.

Especially for Linux, it's perfect.The zEnterprise platform is perfect for consolidating Linux workloads because of the high I/O bandwidth, business continuity with capacity backup features.”

“Oracle has been consolidated on this platform we are using right now only Oracle on the z196 platform,”

Bernd Bohne, Sparda-Datenverarbeitung e.G., Manager, Central Systems

http://www.youtube.com/watch?v=c7Z19IB5AmE

48

Sparda Datenverarbeitung eGSDV runs a number of very large databases within the virtualized Linux environments … The company also relies on SUSE Linux Enterprise Server to support online banking services for the Sparda Banking Group's 4.2 million customers.

Working with IBM, SDV deployed an IBM z196 at each of its two data centers, activating six Integrated Facility for Linux (IFL) engines on each box.

“Our online banking services process approximately 1,200 online transactions per second, so we simply cannot afford them to fail. SUSE Linux Enterprise Server, which is involved in a significant part of this workload, makes us confident that this will not happen.

Since deploying SUSE Linux Enterprise Server on the IBM z196 we have experienced over 99 percent availability.

This proves that Linux's reputation for stability and reliability is well and truly deserved.

We imagine the solution will play an integral role in SDV's infrastructure for some time to come.”

Business ConnexionThe company was running BMC Remedy IT Service Management Suite on Solaris, and determined that the cost of licensing the underlying Oracle database across numerous processors would make it difficult to offer solutions to clients at a competitive price.

Business Connexion deployed SUSE Linux Enterprise Server for System z* to run a new monitoring solution for clients. The ability to run multiple virtual servers side-by-side on a single mainframe processor ensures low software costs for the solution, enabling Business Connexion to offer a powerful solution at a highly competitive price.

Business Connexion currently has approximately 50 virtual machines across the two mainframes—a mixture of database servers, application servers and proxy servers for several different hosted clients.

Results:

– Created a flexible environment for hosted services– Delivered high performance for Oracle databases– Enabled competitive pricing for client services

“With SUSE Linux Enterprise Server for System z, we get excellent performance and bullet-proof reliability—plus it’s easy and cost-effective to manage.”

- Frans Labuschagne, Senior Manager for Open Systems Support Services, Business Connexion

Idaho Power Company Moved to SUSE Linux Enterprise Server on IBM System z to Improve Performance and Reduce Costs

“The power and performance of our SUSE Linux Enterprise environment would have required 3-4 times the amount of money to replicate in other computing environments.”

— Ron Keogh, IT Project Manager for Idaho Power

Company

Working with SUSE Consulting, the Idaho Power IT staff consolidated 30 servers to its mainframe environment using a hosting z/VM operating system for a substantial reduction in server costs.

This consolidation has also significantly reduced the company's Oracle licensing costs.

The IT staff can add a virtual Linux server in a matter of hours. Such consolidation has dramatically reduced both hardware and software licensing costs, providing an immediate return on investment.

Idaho Power now has a stable and reliable infrastructure that gives users access to resources four times faster than before. The company has also increased system performance to respond more quickly to customer issues and power outages.

Canada Dept. of National DefenceFrom mainframe serving to hybrid enterprise hosting

Business challenge: Here was the challenge presented to John Palmer by his director, Winston Sorfleet: “I want you to find new ways to use and grow the [new mainframe] technology.” In a large organization with a variety of platfoms, competing IT agendas, and a history of diffuse control, this is easier said than done.

Solution:The Canada Department of National Defence (DND) path to enterprise hosting with the z196 began with consolidation within the mainframe group itself. Palmer brought all three existing mainframes under centralized organizational management. This entailed the consolidation of all mainframe-related tasks, including:Hardware / Software / Storage supportContracting for Software / Hardware / MaintenanceBusiness Recovery contract managementRole of BR Manager transferred as wellTransfer of all mainframe-related funding

At DND Palmer certainly encountered resistance. He overcame the resistance by setting up a proof of concept (POC) around Oracle running with SUSE Linux Enterprise Server for System z. Based on the results of the POC, Palmer could build a compelling business case emphasizing the dramatic licensing cost savings. With the strong support of management, the mainframe group prevailed.

Benefits:You continue to manage/administer your applications as before—the mainframe is only managing the virtualized

hosting platform they are running on.Your AIX®, Linux, Power, and x-based skills continue to be valuable—those operating systems and platforms

remain viable and active in the enterprise as do the applications running on them. Thus, your skills continue to be in demand.

You get rid of platform headaches—the System z team will manage the platforms while you get to do the rewarding work with the applications and users without platform worries.

State of Oklahoma Dept. of Human ServicesMaking a Difference for the Business and Consolidating Servers

“We were so close to the end of our lifecycle on HP-UX, and the hardware was getting very expensive to support,” says Sunni Majors, director of Enterprise Technical Services.

“By moving Oracle to the Linux System z platform, we were able to restructure costs for CPUs and move away from licensing by user. This gave us a better return on our investment, since we experienced significant savings in our hardware and software licensing costs by consolidating resources onto a single platform.”

OKDHS IT also was pleasantly surprised at the ease of the server and application migration to Linux on System z, although it remains vigilant when it comes to asset management and TCO throughout its IT architecture.

The Government of Québec Saves Money and Resources by Consolidating on an IBM System z

“Disaster recovery is better, our environment is very robust and the performance, security and resource sharing with our Oracle databases is very good - and certainly much better than we had had before.”

— Karen-Ann Plourde,project manager with Direction Générale des Technologies de

l'Information et des Communications (DGTIC)

"Oracle billing is based on how many processors it's running on, and with the new needs, we were requiring between 40 or 50 licenses," notes Karen-Ann Plourde. Realizing that there was the potential for massive cost savings, the organization began searching for a solution that would help it consolidate its many Oracle database instances on fewer processors. As part of this process, it looked at such platforms as UNIX, Intel and virtualization on midrange Linux boxes. None of them, however, gave it the savings it was seeking.There's consolidation and then there's consolidation. What's the difference? Well, how about putting 200 Oracle databases as opposed to, say, one or two or even six databases onto one server.

It's no longer a matter of one or two or three LPARs on a machine, but such innovative combinations of technology as Linux married to the z/VM platform. There appears to be no limit as to how much one can consolidate on a single virtualized machine.
