Exalogic Elastic Cloud Software – PeopleSoft Optimizations PeopleSoft Reference Architecture on Exalogic MAA Best practices PeopleSoft on Exalogic Case Studies – City of San Francisco, Cognizant Demo Summary 1 2 3 4 5 6 7 Oracle Confidential – Restricted

4 PeopleSoft on Exalogic: Anti-Patterns Observed…
Multiple PeopleSoft Environments Port conflict, session state Hardware (F5) & Software Load Balancers (Apache) vs OTD on Exalogic Non-separation of JVMs PIAs for FS, TE, HR – traffic crisscrossing Integration Broker on same JVM as PIA Scheduler logs For recovery & DR, log file share locations and continuous replications Choice of protocol Not TCP over JDBC, but rather SDPoIB JOLT over RDMA - PT 8.53+ PeopleTools mid-tier Shared storage use by different VMs Patching/upgrading multiple VMs COBOL is chatty. Scheduler on Exalogic. PeopleSoft Application database PUM, SYS DB, SES DB, migrate to Exadata Let’s begin our journey to embark on best ways to onboard PeopleSoft workload on Exalogic & Exadata…….

24 San Francisco’s Exa Story
San Francisco Overview Exa Upgrade Objectives and Criteria Exa Upgrade Implementation Timeline Then and Now Performance Maximum Availability Architecture Looking Back: Challenges and Lessons Learned Final Thoughts

25 City of San Francisco PeopleSoft 9.0 (Ben, HR, TL, Absence, Payroll,eSuites) Original 9.0 Implementation: Aug 2012 25 Environments on HCM 9.0 and HCM 9.2 (Upgrade) Production= 211 GB (compressed) 6 GB growth biweekly 30k employees, 100,000k covered lives, $100m payroll Controller’s eMerge (PeopleSoft) Division = 40 FTE Responsible for application (4 FTE), OS (2 FTE) and hardware Department of Technology: =200 FTE Responsible for database, storage, network and datacenters

26 Upgrade Project Objectives
Refresh Hardware Move to new Production Data Center Move to new Disaster Recovery/Test/Dev Data Center Simplify Architecture

27 San Francisco’s Exa Implementation Timeline
Upgrade Exadatas to 1/4 rack Exalogic new 1/8 rack Inception Excite Process Kickoff May 9th Install at New Production Data Center Dec 12th -20th Install at New Test/DEV/DR Data Center Feb 10-21st Go-Live June 6th Datacenter Lease Signed July 10th RFQ Issued October 25th Vendor Selected November 5th 1G Connection Established Jan 17th Apply July Patch Aug. 15th-28th Apply April Patch May 19-22nd Review and Analyze Procure Install & Configure Test & Develop Deploy Optimize May-13 Jun-13 Jul-13 Aug-13 Sep-13 Oct-13 Nov-13 Dec-13 Jan-14 Feb-14 Mar-14 April-14 May-14 June-14 July-14 Aug-14 Sept-14 Infrastructure Moved to 2 new data centers Built Test/DEV/DR from floor-up Established connectivity Hardware 2 1/8 rack Exadatas 2 1/8 rack Exalogics UCS for Windows Operating/Database System Upgraded from PT to 8.5.3 Implemented RAC Implemented Active Dataguard Expanded OEM usage Implemented GoldenGate

28 Reference Architecture
Simplify the visio!

29 Hardware Refresh: Key Criteria
Create a stable, scalable base for future work Increase performance Implement MAA/DR Reduce Total Cost of Ownership: How? Simplify architecture across data centers: reduce training time Increased automation via OEM: more time for value added work One vendor: less time troubleshooting Increased performance: less overtime, more time for Q/A Other options considered: new blades, Vblock, hybrid model

30 Challenge Recommendation Oracle Stated Benefit CCSF Observation Complex Architecture Database Tier Install Exadata Engineered Solution lower cost and risk Has been met or exceeded Complex Architecture Application Tier Install Exalogic Engineered Solution with predefined PeopleSoft templates Has been met or exceeded, some issues with upgrade templates Live Reporting & Robust DR Install Golden Gate Active DataGuard Fast and Flexible Data Replication Single Points of Failure Install Real Application Clusters (RAC) High availability reduce risk Has been fully met Staff overload Leverage Enterprise Manager Automated proactive infrastructure monitoring, Mgmt, and diagnostics In progress, so far so good Leverage PeopleSoft Mgmt Pack Comprehensive, application performance & config Mgmt Updating/Patching system Oracle Support Removes complexity and transfer responsibility to Oracle from project team Has been met, some issues with front line team

31 MAA: Highlighted Examples
Rolling patching: no overtime and no outages for end users Failover: DR test was planned and implemented in a few hours, SunGard test took months of planning time Replaced parts in production chassis during workweek Exachecks: proactive monitoring, great Oracle Support Use of ZFS Exalogic Shares via Vservers to manage images of PeopleSoft HOME & Oracle HOME: makes everything easy

32 Maximum Availability Component Then Now Comment RAC No Yes Unable to implement on blades ExaCheck MAA Report Regularly Run and track faults/warnings lets us be proactive Active Dataguard With PeopleTools have secondary to keep online sessions active Templates Night and day difference in server creation turn around times hours not days or months with full procurement Patching Ability to patch during workweek and transfer responsibility (hardware/OS)

33 Performance More than just run time improvements….
Trouble shooting is much faster and smoother End User Experience: “the pages jump at you” Templates: spun up PeopleSoft 9.2 Environments in ½ a day, previous lifecycle would have been months or weeks Increased from 1,000 end users in June to 3,00o today, with plans to grow to 30,000 in early 2015

34 Performance Improvements
Highlighted Tasks Benchmark time Exadata time Time Gained % change Create Pay Sheet 14 4 10 250% Load Time Data 45 25 20 80% Prelim Calc # 1 48 28 140% Pre Confirm Audit Report 27 3 24 800% Pay Confirmation 62 21 41 195% Absence Process (Entitlement-Calc) 22 12 120% Create Pay Checks  (XML Testing) 5 100% Create Pay Advice  (XML Testing) 23 92% Distribute cost of Time & Labor 38 30 8 27% CCSF Payroll Register report 73 18 54 304% Retirement services files 39 15 62% Talx E-Pay 109 36 72 196% Talx Unemployment file 11 9 75%

35 Payroll Processing Timeline*
Time Savings 7 hours 5.5 hours Payroll Processing Performance Improvements    1.5 hours DataGuard Backup Payroll Processing Timeline* Tues Wed Thurs Before Hours 6 10 8 end time 7:00 PM 9:00 PM or later 5:00 or later After 5 6:00 PM 6:00 PM or earlier 3:00 PM *excludes application and database processes that run after payroll. Payroll Processing Improvements: how we used the 7 hours Return to more normal work life balance More time for quality assurance and data entry tasks Will return slack time to end user departments: goal is 1:00 PM on Thursday

36 Looking Back…. Recommendations… Oracle to do…
Plan for growth from day one Training should be “just in time” hard to relate to scale of change Don't deviate from best practice; listen don’t do it the old way Develop documentation and procedures that work for your organization there is no one size fits all Oracle to do… Improve documentation for first timers 800 page user manuals are too dense: need quick reference guides Improve Platinum Gateway experience Issues with template during initial move and build

37 Final Thoughts Are we confident we made the right decision? YES Why?
Total Cost of Ownership Scalability: ability to scale up and scale down is a game changer One vendor is really, really nice What’s next? Purchased two new Exadata 1/8 racks and new Exalogic 1/8 rack for Oracle Identity Manager and other applications

39 PeopleSoft ESA, Fin, HR on Exalogic MAA
Cognizant’s PeopleSoft ESA, Fin, HR on Exalogic MAA Global Large Critical And, got problematic Peak time slowness More and more servers Lack of ability to scale Longer maintenance window

40 Oracle Exalogic Solution? Exalogic upgrade on web layer
Lintel / Weblogic Benefits 50% improved downstream integration processing Server consolidation – 5:1 Maintenance window reduced to few hours Support effort down 50% Better CPU utilization – 3:1

41 Didn’t quite stop there…
Oracle Exadata Performance woes 10-15 slow incidents/month Batch failures / over runs Slow online pages due to DB2 table locking Long running SQLs Inability to scale for volume DB2/AIX 3 Options, 1 Pick DB Layer upgrade to Exadata

42 Implementation, Outcomes & Benefits
Strict timelines Conversion of ~6,000 SQLs Constantly changing production system Only <3 days available for cut over Full DR 60 hours cut over DR upgraded same time as production No major post production issues Financials close batch jobs complete 56% faster Payment batch jobs run 93% faster Customer billing batch jobs run 55% faster RTO for DR down rom hours to near-zero Transactions with <1s response 75% from 30% Batch window reduced to ~4 hours from 10+ hours Huge floor, and power saving 24x7 availability

43 Cognizant’s Application Landscape
