increased predictability.

O er the la t e ear , grid computinginwhich groups o independent, modular hardware andso tware components can be virtualized and provi-sioned on demandhas rapidly moved rom being aleading-edge concept to being a widely adopted prac-tice. Oracle introduced grid computing capabilities in2003, and continues to lead the so tware industry inits commitment to grid computing and virtualization.Today, more than 10,000 organizations have deployedOracle grid computing solutions.

In essence, companies are embracing grid comput-ing because it o ers a clear solution to many o the

undamental challenges acing IT organizations today.For example, by pooling computing resources, gridcomputing helps ensure that IT is agile enough to stayin step with changingand o ten unpredictablebusiness needs. Grid computing also helps ensure highavailability, with the ability to manage workloadsacross the grid, and to add capacity without interrupt-ing operations.

Above all, grid computing lets companies achieve suchbenefts at relatively low cost. It provides a range o savings through the use o standard hardware, greater

e fciencies, better capacity planning, and increasedpredictability. For example, grid workload manage-

ment and resource provisioning help companies meetgrowing workload requirements without adding sta .Also, because computing resources can be appliedincrementally when needed, companies typically seebetter computing and storage capacity utilization, andcan avoid the expense o over-provisioning as a hedgeagainst unpredictable demand increases.

Oracle Real Application Clu terOracle Real Application Clusters (Oracle RAC) supportsthe transparent deployment o a single database across acluster o servers, providing ault tolerance in the evento hardware ailures or planned outages. With OracleRAC running on clustered servers, companies can havehigh levels o availability and per ormance and easilyscale up operations while controlling computing costs. Oracle RAC gives companies a oundation or enterprisegrid computing built rom standardized processing,storage, and network components. It enables the OracleDatabase to run on a grid plat orm, and lets compa-nies dynamically provision nodes, storage, CPUs, andmemory while the system remains onlineprovidingsimplifed, e fcient maintenance while supporting highavailability.

Oracle RAC can be used with mainstream businessapplications o all kinds, including Oracle E-BusinessSuite, PeopleSo t, Siebel, SAP, and custom applica-tions. It supports OLTP and DSS applications, as well asOracles unique ability to e ectively work with mixedOLTP/DSS environments. And it provides single-imageinstallation and management, giving database adminis-trators a single point o control or managing a clustero multiple servers.

Oracle RAC provides: Lower costs. With Oracle RAC, clusters can be

built rom standardized, commodity-priced process-ing, storage, and network components. In addition,

the so tware helps reduce the cost o downtime. Forexample, Pacifc Gas & Electric saw Oracle RAC as away to cost-e ectively handle growing data volumes

rom its smart-meter program, says Eugene Park,senior director o application services at the com-pany. Weve actually been able to save over $5 mil-lion a year by re-plat orming rom our main rame toOracle RAC. We saw that Oracle RAC would allowus to pretty easily add additional servers and addi-tional storage to grow our processing capabilities.Today, on our customer care billing system, we havemore than 300 terabytes o data spinning to supportour smart-meter in rastructure.

24/7, continuous uptime or database applica-tions. Oracle RAC eliminates the single-point-o -

ailure arrangement that is inherent with a singleserver. I a node in the cluster ails, the OracleDatabase continues running on the remaining nodes.Individual nodes can be shut down or maintenancewhile application users continue to work.

On-demand, exible scalability. IT organizationscan expand capacity by simply adding servers to thecluster as more processing power is neededwhichcan be done without taking users o ine. As soonas the new server is in place, the application takesadvantage o the additional capacity, and serversdo not need to have the same capacity: Companiestoday run a range o Oracle RAC clusters, romthose where each server is a two-CPU commod-ity server to those where there are 32 to 64 CPUs

in each server. One o the large Oracle RAC sys-tems we have is a 16-node system with six storage

Indeed, Oracle RAC can deliver high per ormance witha variety o applications and workloads. One o thethings we were concerned about when we frst got intoReal Application Clusters was how well it would sup-port our mixed workload o OLTP and decision sup-port, says Michael Prince, chie technology o fcer atBurlington Coat Factory. The answer is that it has sup-ported them very well. We get great per ormance romRAC, both or our OLTP and or our decision support.

Oracle Acti e Data GuardIT organizations ace a undamental challenge:Improve quality o service while reducing costs andcomplexity. Oracles Active Data Guard helps themachieve consistent high per ormance by o oadingresource-intensive activities rom a production databaseto one or more synchronized standby databases.

Active Data Guard is based on Oracle Data Guard,a eature included in the Oracle Database EnterpriseEdition. Data Guard keeps standby databases synchro-nized with a primary database. I the primary databaseexperiences an outage due to data corruption, system

ailure, human error, or disaster, Data Guard canquickly switch any standby database to the production

role, minimizing downtime and preventing data loss.Oracle Active Data Guard enables a physical standbydatabase to be open or read-only access or report-ing, simple or complex queries, sorting, Web-basedaccess, and so onwhile changes rom the productiondatabase are being applied to it. All queries reading

rom the physical standby database execute in realtime and return current results. This means that anyoperation that requires up-to-date read-only access canbe o oaded to the replica database, enhancing andprotecting the per ormance o the production database.The potential or that type o unctionality is huge,says Logan McLeod, IT strategist at Dell. It nowmeans that I can potentially use my DR environments

or high-volume reporting without impacting my pri-mary databases.

This capability makes it possible or Active DataGuard to be deployed or a wide variety o businessapplications. For example, fnance operations can useActive Data Guard or ad hoc queries and reports. Inthe telecommunications industry, it can be used toprovide technicians with access to service schedulesand to handle customer inquiries about service status.In healthcare, it can enable ast access to up-to-datemedical records. In transportation, it can support pack-age tracking and schedule status inquiries. And Webbusinesses can use it to support catalog browsing, orderstatus, and scale-out initiatives using reader arms.

Oracle la h ackHuman error plays a signifcant role in availabilityand research shows that 40 percent o applicationoutages are caused by operator or user mistakes. Theseerrors are extremely di fcult to avoid, and can beparticularly di fcult to recover rom without advanceplanning and the right technology.

Typical user errors include accidental deletion o valu-able data, deleting the wrong data, and dropping thewrong table. Such errors can result in logical data cor-ruption, or cause downtime o one or more componentso the IT in rastructure. While it is relatively simple torecti y the ailure o an individual component, detec-tion and repair o logical data corruption is typically a

time-consuming operation that causes enormous loss o business productivity.

Oracle Flashback enables IT organizations to view andrewind data back and orth in time, without having tomake any structural changes to the database. It pro-vides a simple, power ul, and completely nondisruptivemechanism or recovering rom human errorsandreduces recovery time rom hours to minutes.

Flashback technology revolutionizes recovery by oper-ating just on the changed data. Thus, the time it takesto recover rom the error is equal to the time it took tomake the mistake. With the technology, organizationscan query historical data, per orm change analysis,and per orm sel -service repair to recover rom logi-cal corruptions while the database is online. Flashbacktechnology can also be utilized or nonrepair purposes,such as historical auditing and undoing test changes.

Oracle Auto atic storage manage entStorage plays a vital role in availability, and it can pre-sent a signifcant challenge to IT organizations tryingto do more with less. To help, Oracle provides OracleAutomatic Storage Management (ASM), an integrated,high-per ormance database fle system and disk man-ager. ASM is based on the principle that as much as pos-sible, the database, rather than administrators, shouldmanage storage. ASM eliminates the need to directlymanage potentially thousands o Oracle database flesand helps protect vital data in the event o a disk ailure.

Storage had grown to be

ASM has been a revolution in terms o the waywe manage storage, says Michael Prince, chie tech-nology o fcer at Burlington Coat Factory. Storage hadgrown to be the most di fcult and most costly com-ponent o the database architecture, and certainly themost di fcult to manage. And ASM has simplifed itdramatically.

ASM groups the disks in a storage system into oneor more disk groups. The IT organization then man-ages a small set o disk groups, and ASM automatesthe placement o the database fles within those diskgroups. ASM provides: Striping. ASM spreads data evenly across all

disks in a disk group to optimize per ormance andutilization. This even distribution o database fleseliminates the need or regular monitoring and I/Oper ormance tuning. When reading a fle, ASMreads data rom all six disks in parallel, greatlyincreasing per ormance.

Mirroring. ASM can increase availability by option-ally mirroring any flethat is, keeping redundant,or mirrored, copies o data to help avoid data losscaused by disk ailures. I a disk ails, ASM can con-tinue to access a ected fles by accessing mirroredcopies on the surviving disks in the disk group.ASM supports two-way mirroring, where data getsone mirrored copy, and three-way mirroring, wheredata gets two mirrored copies.

Online storage reconfguration and dynamicrebalancing. ASM lets companies add or removedisks rom a disk storage system while the database

is operating. When a disk is added, ASM automati-cally redistributes the data so that it is evenly spreadacross all disks in the disk group, including the newdisk. This redistributionor rebalancingis donein the background with minimal impact to databaseper ormance. When a disk is to be removed, ASMrebalances by evenly relocating data rom the diskbeing removed to the other disks in the disk group.

maxi u A aila ilit ArchitectureThese various Oracle technologies can be vital, buttechnology alone is not always enough to ensure highavailabilityoperational best practices are also key. Tothat end, Oracles Maximum Availability Architecture(MAA) provides a ully integrated and proven blueprint

or building highly available systems using Oracle Data-base options such as Oracle RAC, Oracle Active DataGuard, Oracle Flashback, and Oracle ASM.

Oracle MAA gives companies superior data protectionand availability by minimizing or eliminating plannedand unplanned downtime at all technology stack lay-ers, including hardware and so tware components. Thearchitecture encompasses specifc design and confgu-ration recommendations that have been extensivelyreviewed and tested to ensure optimum system avail-ability and reliability. In addition to Oracle high-availability options, the architecture also addresses theconfguration and integration o other critical compo-nents o highly available systems, including servers,storage, networking, and the application server.

MAA best practices are described in a series o techni-cal white papers and documentation designed to helpin the design, implementation, and management o anoptimum high-availability architecture. Companies candraw on MAA best practices or areas such as OracleDatabase, Application Server, Applications, Grid Con-trol, and Oracle Partners.

Oracle Ad anced Co pre ionOracle Advanced Compression helps companies man-age growing amounts o data in a cost-e ective manner,while maximizing the utilization o resources. It enablescompression or all types o datastructured data,unstructured data, and backup data, as well as networktra fc and data in the process o being backed up. As aresult, Oracle Advanced Compression helps companiesuse resources more e fciently and lower storage costs.

In terms o per ormance, Oracle Advanced Compression: Has no adverse impact on query per ormance,

because queries read the compressed version o datadirectly without having to decompress it. In act,query per ormance may improve due to improveddisk scan rates and a reduction in the number o I/Os.

Provides enhanced memory e fciency, becausedata in memory is in a compressed ormat. Thisallows more data to be stored in memory andreduces the number o I/Os, which may improveper ormance.

Provides enhanced Data Guard and OracleRAC per ormance due to reductions in network/interconnect tra fc.

Oracle Advanced Compression also helps lowerstorage costsin act, companies may see 3X orhigher reductions. Whats more, it is designed tocascade storage savings throughout the data center,and extend them to test, development, backup, anddisaster recovery environments, urther magni yingthe cost savings. It helps reduce resource require-ments and costs or all components o the IT in ra-structure, including memory, backup media, andnetwork bandwidthwhile improving applicationper ormance and enhancing memory and networke fciency. And it can support todays growingemphasis on green operations, due to its reducedneed or energy and space.

Data ha al a een a critical a et in busi-ness, but today, it is more important than ever or com-panies to ully leverage this asset.

As IT executives know, business decision makers aredemanding more and more in ormation. Compa-nies need to not only analyze and report on what hashappened, but also use data to predict behavior andidenti y trends going orward. And in a world wherethe pace o business is increasing relentlessly, they needup-to-date in ormation that can help them respondand act in near-real time.

To meet those needsand help the company get themost value out o its dataIT organizations need totake advantage o todays sophisticated data warehous-ing technologies. They need to gather and managelarge amounts o data rom a variety o sources. Andthey need to help the business distill that data intoinsights about customers, markets, and per ormanceand use it to compete more e ectively.

Oracle helps companies make the most o their datawith several data warehousing-related options or theOracle Database. These include: Oracle Exadata

Oracle Partitioning

Oracle Data Mining Oracle OLAP

Oracle ExadataOracle Exadata is a amily o high-per ormance storageso tware and hardware products that can improve datawarehouse query per ormance by a actor o 10Xormore.

To deliver that per ormance, Oracle Exadata usesa massively parallel architecture that dramaticallyincreases data bandwidth between the database serverand storage.

Oracle Exadata Storage combines smart storage so t-ware rom Oracle and industry-standard hardware romHP to create the HP Oracle Exadata Storage Server.This solution is based on the HP ProLiant DL180 G5servera ast, reliable, high-capacity, industry-standard storage building block. With a choice o SAS or SATA drives and a storage capacity o up to12 terabytes per server, it comes with Oracle Exadataso tware preinstalled.

HP Oracle Exadata Storage Servers deliver per ormanceimprovements in data-intensive query processing,have virtually unlimited I/O scalability, are easier tooptimize or data warehousing, and provide mission-critical availability and reliability. They also provide a

It o ers unlimited scal-ability, with the ability to simply connect additionalOracle Exadata Storage Servers as needed. And it lets

companies get up and running quickly, with a com-plete package o HP hardware and Oracle so tware.

Oracle PartitioningWhen data volumes increase, a common concern is thatsystem per ormance will su er because o all the extradata that has to be examined. Partitioning enables tablesand indexes to be split into smaller, more manageablecomponents and is a key requirement or any largedatabase with high per ormance and high availabilityrequirements.

Oracle Partitioning o ers the widest choice o parti-tioning methods, allowing tables, indexes, and index-organized tables to be subdivided into smaller pieces, sothat they can be managed and accessed at a fner level o granularity. Using partitioning within Oracle databasesgives us a lot o advantages, says Sean Wiley, CTO anddirector, EDS Application Services, EDS. For instance,we can segment very large tables within a database,based on month or other characteristics, so that we getthe per ormance characteristics o a much smaller tableand the management characteristics o a much smallertable, within that larger data set.

With thisoption, companies can explore their data to fnd patternsand insightsto target their best customers, fnd andprevent raud, identi y drivers o per ormance, and so on.Oracle Data Mining also lets IT pro essionals auto-mate the discovery and distribution o new businessintelligence. As a result, companies can go beyond thetraditional manual searching and querying o in orma-tion to quickly and automatically look through mas-sive amounts o data in order to predict, understand,and develop new insights.

Oracle Data Mining represents a breakthrough in thebusiness intelligence arena. Traditional data-miningapproaches have typically orced companies to extractdata rom the database and move it to separate, unse-cured, and costly dedicated statistical, analytical, ormining servers. Oracle Data Mining, on the otherhand, is embedded in the Oracle Database. Thus, it

Organizations can scale up usinglarge SMP machines or scale out using Oracle RACto encompass hundreds o computers while stillpreserving a single system image. With OracleDatabase 11 g, organizations can store all types o content and scale to handle petabytes or exabyteso data.

Deduplication. SecureFiles automatically detectsmultiple, identical SecureFiles data and stores onlyone copy, thereby saving storage space. Deduplica-tion not only simplifes storage management, butalso results in signifcantly better per ormance.

Compression. Data is compressed using industry-standard compression algorithms. This compressionresults in signifcant savings and better per ormancedue to I/O, bu er cache requirements, redo genera-tion, and encryption overhead improvements.

Encryption. In 11 g, Oracle has extended theencryption capability to SecureFiles and uses theTransparent Data Encryption (TDE) syntax.

Oracle Spatial has given

us the ability to simpli y

essentially our management

o spatial data, bringing it

all into one environment.

Advanced logging. Oracle supports transactionalconsistency or unstructured data by logging boththe metadata and data changes. File systems, onthe other hand, usually log only the metadata andnot the fle data changes. Oracles approach enablescompanies to recover completely rom media ail-ures, a capability that is not available with genericfle systems.

Oracle spatialOracles geospatial option, Oracle Spatial, is a compre-hensive spatial database o ering designed to meet theneeds o advanced GIS business and government appli-cations, including business intelligence and systems

or land management, utilities, de ense, and homelandsecurity. It includes native support in Oracle Database11 g or vector and raster data, topology and networkmodels, 3D data, geocoding, routing, and OGC-standard Web Services. And its open, native spatial

ormat eliminates the cost o separate, proprietary sys-tems, and is supported by all leading GIS vendors.

Oracle Spatial is designed to help organizations achievea variety o benefts, such as:

Saving administration and in rastructure costs, by consolidating spatial data assets

Streamlining business processes and improv-ing quality and service, by integrating locationintelligence into applications

Providing enterprise-wide spatial access, byenabling all stakeholders to use spatial data with-out additional so tware

Managing spatial in ormation with maximumsecurity, scalability, and per ormance, by lever-aging existing Oracle technology and skills

Not surprisingly, Oracle Spatial is the industrys lead-ing spatial database management plat orm. Industryanalyst IDC reports that Oracle is the most widelyused enterprise spatial database server, with more than80 percent o the enterprise spatial database marketand that Oracle has developed the deepest spatialcapabilities among the IT in rastructure players. AndIDC notes that because the spatial eatures are accessi-ble through standard languages such as SQL and Java,developers can integrate spatial eatures directly intobusiness and location-based applications at relativelylow costs and with minimal training.

combines the qualities o a

qualities o an enterprise

Because it is easy to use, Oracle APEX is especiallyuse ul in quickly building opportunistic and depart-mental applications that report on database data.Reports are typically hypertext-linked with otherreports, allowing users to navigate through databasedata in the same way they navigate Web sites. Columnsin reports can be easily linked to other reports, charts,and data entry orms. An extensive charting engineallows SQL queries to be represented graphically, allow-ing data to be more e ectively communicated.

Historically, departments and small projects haverelied on desktop databases to provide an agile devel-opment tool or smaller-scale development needs.However, these can become very ragmented becausethey keep data in too many places, they can be inap-propriate or use with sensitive in ormation, and theyare typically not Web riendly. Oracle APEX addressesthat problem by combining the qualities o a personaldatabase, such as ease o use and exibility, with thequalities o an enterprise database, such as security,integrity, scalability, and availability.

Data ecurit ha een a ke concern or ITorganizations or some time, and that concern con-tinues to grow. For companies that experience a databreach, the fnancial, legal, and reputational costs canbe quite high. Whats more, a range o regulations, suchas Sarbanes-Oxley, Payment Card Industry (PCI) DataSecurity Standard (DSS), and the Health Insurance Por-tability and Accountability Act (HIPAA) now requirecompanies to implement measures to protect sensitivein ormation and monitor access to that in ormation.

Today, companies have to protect against not onlyexternal intrusions, but insider threats as well. Indeed,research rom the Computer Security Institute and theFBI shows that more than 70 percent o in ormation-system data losses and attacks are perpetrated by insid-erspeople inside the company who are authorized toaccess the system at some level. In response, many ITdepartments are working to sa eguard the sensitive datain their databases.

rom unauthorized access and modifcation. OracleDatabase Vault helps companies comply with thoserequirements with strong controls designed to protectdata against threats rom insiders.

It does so by providing two basic capabilities:(1) It provides tools or preventing highly privilegedusers, such as administrators, rom gaining unauthorizedaccess to sensitive application data. (2) It lets companiesuse multi actor control policies that determine when,where, how, and by whom applications, database, anddata can be accessed actors such as time o day, IPaddress, application name, and authentication method.This multi actor control helps prevent unauthorizedad hoc access and application by-pass.

or the entire change li ecycle Scalable, and able to handle small and large

changes Predictable, because it trans ers the exact resolu-

tion o changes rom testing to production Cost e fcient, reducing testing e ort by up to

80 percent

Oracle Real Application Testing includes two key ea-tures: Database Replay and SQL Per ormance Analyzer.

Database Replay lets IT pro essionals accurately andrealistically re-run actual production workloads,including online user and batch workloads, in testenvironments. It captures the ull database workload

rom production systems, including all concurrency,dependencies, and timing, essentially re-creating pro-duction workloads on the test system. With it, data-base and systems administrators can test:

Database upgrades, patches, parameter, schemachanges, and so on

Confguration changes, such as conversion rom asingle instance to Oracle Real Application Clusters,Oracle Automatic Storage Management, and so on

Storage, network, and interconnect changes Operating system, hardware migrations, patches,

upgrades, parameter changes

With Database Replay, IT pro essionals can test theirchanges without the overhead o having to duplicatean entire application in rastructure. And the optioncan be deployed quickly: It does not require DBAs tospend months developing unctional knowledge o theapplication and test scripts. Instead, with a ew point-and-clicks, they can have a ull production workloadavailable at their fngertipswhich helps reduce test-ing cycles rom many months to just weeks or days.

SQL Per ormance Analyzer helps predict and pre-vent SQL execution per ormance problems caused bychanges in the IT environment. It provides a granularview o the e ect that changes will have on SQL execu-tion plans and statistics by running the SQL statementsserially be ore and a ter the changesand provides areport outlining the net beneft. It completely auto-mates and simplifes the manual, time-consumingprocess o assessing the impact o change on extremelylarge SQL workloads, which can involve thousands o SQL statements.

Such capabilities can have an important impact onthe business. As Sean Wiley, CTO and director o EDS Application Services at EDS, points out: Withhundreds o databases in the environment, and morecoming all the time, the ability to test in the real-li escenarios here, and understand how the productiondata will per orm, is just essential to us providingquality service to our clients.
