1 Intrductin by Surekha Parekh In the current ecnmic climate, businesses are under significant pressure t cntrl csts and increase efficiency t imprve their bttm line. IBM DB2 fr z/os custmers arund the wrld are still trying t gain cmpetitive advantage by ding mre with less: mre business insight, mre perfrmance, mre peratinal efficiency, mre functinality, and mre prductivity with less cst, quicker time t market, and a lwer TCO. DB2 11 helps custmers address key business issues by delivering innvatins and business benefits in the fllwing imprtant areas: Even mre ut-f-the-bx CPU savings: Up t 10% fr cmplex OLTP Up t 10% fr update-intensive batch Up t 40% fr queries Up t 25% fr uncmpressed tables and 40% fr cmpressed tables Enhanced resiliency Fewer planned utages, fewer REORGs, faster recvery Cst-effective archiving, ability t access warm/cld data in a single query Business-critical analytics DB2 Analytics Acceleratr perfrmance enhancements Big data integratin In-transactin realtime scring Advanced QMF analytic capabilities with mbile supprt Simpler, faster upgrades fr faster ROI 16X faster catalg migratin Prtectin frm incmpatible changes Repeatable testing with real wrklads and integrated clning

2 x DB2 11: The Ultimate Database fr Clud, Analytics, and Mbile We have seen many tp 10 lists arund DB2 11; in this sectin, we summarize the tp 10 reasns why we feel it is the right time fr custmers t upgrade t DB2 11. We all knw that supprt fr DB2 Versin 10 will be withdrawn frm Marketing n July 6, Hwever, there are many mre reasns t migrate; users will see significant benefits frm DB2 11. Tp 10 Reasns t Upgrade t DB2 11 fr z/os 1. Reduced COSTS! Even mre cst savings up t 40% 2. Business analytics fr realtime decisin making made simple 3. Enabled fr big data and clud phenmenn! 4. Enabled fr a mbile wrld with wrld-class JSON datastre 5. SPEED! Simpler, faster migratin fr FASTER ROI 6. TRUST ENHANCED RESILIENCY 24x7 7. UNMATCHED DATA SECURITY in the industry 8. Certified fr SAP applicatins frm day 1 first time in histry 9. Industry-leading Optimizer gets even better! 10. Imprved prductivity with DB Reduced Csts: Even Mre Cst Savings Up t 40% DB2 11 helps yur bttm line with ut-f-the-bx CPU savings fr nline transactin prcessing (OLTP), batch, and query wrklads t help yu get the mst ut f yur investment. These savings range up t 40 percent, depending n the wrklad. Additinal savings and perfrmance imprvements may be fund by leveraging DB2 features and making applicatin changes. Transparent archive capabilities help keep mre data available with imprved perfrmance and reduced strage csts. Specialty engines cntinue t add value fr many IBM clients. DB2 11 delivers additinal prcessing that is directed t execute under enclave SRBs and authrized t execute n a ziip specialty engine, which can prvide additinal cst savings and efficiencies in yur System z envirnment. 2. Business Analytics fr Realtime Decisin Making Made Simple Business analytics is nw business-critical. DB2 11 makes it easier t bring analytic cmpnents clser t the cre peratinal data reducing latency, cmplexity, and csts while imprving data quality and gvernance. Imprved query, lightning-fast

Enabled fr Big Data and Clud Phenmenn Few IT prfessinals can have missed the big data and clud phenmenn that has manifested itself in recent years. Despite the undeniable value f the highly structured peratinal data held within enterprise applicatins, a vast amunt f less-structured data is being generated by scial media streams, telemetry, click streams, and many ther surces. Being able t analyze these big data surces undubtedly hlds significant value fr many rganizatins, but the sheer vlume and velcity at which the data is prduced makes it a very challenging task fr traditinal database systems. In respnse t this, a number f tls and techniques have emerged centered n the pen surce Hadp framewrk, including IBM s InfSphere BigInsights technlgy. While these technlgies address many f the challenges inherent in the analysis f big data, they als intrduce new nes fr rganizatins wanting t gain new insights by integrating the analysis f big data with cre peratinal infrmatin. DB2 11 delivers sme highly significant new features t allw DB2 and Hadp/BigInsights t wrk tgether and better leverage each platfrm s respective strengths. This capability allws data t flw in bth directins between DB2 and BigInsights, and frm BigInsights t DB2. The new integratin capabilities delivered within DB2 11 allw rganizatins t mre easily and efficiently cmbine the results f big data analysis with up-t-date peratinal data frm DB2 OLTP databases, significantly increasing the practical value f any insights btained. 4. Enabled fr a Mbile Wrld With a Wrld-Class JSON Datastre With the enrmus grwth f smart phnes and applicatins, custmers everywhere are building systems f engagement using mbile technlgy. These new systems are extremely agile and typically use JavaScript and JSON. Applicatin develpers are pushing fr JSON datastres that they see in the NSQL wrld, and DB2 11 is evlving t be a wrld-class JSON datastre, s yu dn t need t leave DB2 t get these benefits. 5. Speed: Faster Migratin fr Faster ROI The faster an upgrade can be cmpleted, the faster yu can see the return n investment. DB2 11 catalg upgrades are up t 16 times faster than in DB2 10. Additinal access path stability imprvements help maintain and even imprve perfrmance when upgrading t DB2 11, prviding mre stability frm day 1.

4 xii DB2 11: The Ultimate Database fr Clud, Analytics, and Mbile DB2 11 fr z/os intrduces the cncept f applicatin cmpatibility, which enables yu t separate release upgrades frm applicatin changes that may be needed t take advantage f a new functin. New tracing capabilities help identify applicatins that may need changes, and then yu can make plans fr thse applicatin changes independent f upgrade schedules and plans. When the new DB2 versin has been upgraded, the applicatin will run as if it were n the previus DB2 versin. Applicatin changes can nw be scheduled within the applicatin s wn develpment cycle. As the changes are cmpleted, the applicatin can then take advantage f the new capabilities in the new DB2 release. Separating applicatin changes frm database upgrades greatly simplifies planning and als speeds the upgrade itself. Optim Wrklad Replay (OWR) lets yu capture, save yur prductin wrklads, and then replay them in test envirnments t reduce migratin risk. Yu can identify prblems earlier using validatin reprts and perfrmance tuning, avid prductin utages, and increase prductin stability. OWR is integrated with the DB2 Clning Tl t cst-effectively and easily cpy yur prductin database t yur test envirnment. This single, repeatable prcess can dramatically reduce migratin test effrts and investments while imprving results. 6. Trust: Enhanced Resiliency 24x7 In DB2 11, the legendary resiliency f DB2 has been increased even further. Realwrld prven resiliency and security are sme f the cre reasns why clients chse DB2 and System z. DB2 11 cntinues t raise the bar with additinal capabilities fr even higher availability and resiliency. Online schema enhancements allw changes t database bjects while maximizing availability f the changed bjects. The number f REORG jbs needed has been reduced while, at the same time, delivering perfrmance imprvements f up t 20 percent. Additinal perfrmance imprvements f up t 70 percent fr LOAD and up t 40 percent fr RECOVER drive additinal benefits and resiliency. 7. Unmatched Data Security in the Industry Data security means prtecting a database frm destructive frces and the unwanted actins f unauthrized users. DB2 fr z/os remains the market leader when it cmes t prtecting yur missin-critical data. Bet yur business security has been extended t simplify management and cmpliance. DB2 received a cmprehensive verhaul f its security features within the DB2 10 fr z/os release. DB2 11 adds sme imprtant new functinality, including RACF exit enhancements and clumn masking.

5 Intrductin xiii 8. Certified fr SAP Applicatins frm Day 1 First Time in Histry DB2 11 has been certified fr SAP applicatins at General Availability (GA). This is the first time in the histry f DB2 and the first time fr any new release f any database supprted by SAP. The day 1 certificatin f DB2 11 demnstrates the clse technical SAP/DB2 cllabratin and great stability f the DB2 11 prduct and enables SAP clients t immediately take advantage f the numerus DB2 11 enhancements.
