  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 1/8rack 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 Vendor Selected November 5th RFQ Issued October 25th Datacenter Lease Signed July 10th Apply July Patch Aug. 15th-28th 1G Connection Established Jan 17th Apply April Patch May 19-22nd • Operating/Database System • Upgraded from PT 8.5.0 to 8.5.3 • Implemented RAC • Implemented Active Dataguard • Expanded OEM usage • Implemented GoldenGate • 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

  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. 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

  31. 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

  32. Performance Improvements

  33. 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

  34. Looking Back…. • Recommendations… • 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 8.53.10 template during initial move and build

  35. 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

  36. Maximum Availability Architecture at Cognizant PeopleSoft Systems • Aaron De Los Reyes • Sr. Director, Oracle Technology • Cognizant, Inc Oct 2, 2014

  37. 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

  38. 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

  39. 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 2015+ volume DB2/AIX 3 Options, 1 Pick DB Layer upgrade to Exadata

  40. 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

  41. Cognizant’s Application Landscape PeopleSoft Suite Cognizant’s PeopleSoft Implementation for Corporate functions include - • PeopleSoft Financials/Enterprise Services Automation - GL, AP, AR, AM, CM, PO , T&E, CA, BI, RM, PC • PeopleSoft HCM – Core HR, Absence Management, Time and Labor, Payroll, ePerformance, Self-Service, Workforce Administration, Recruitment, eCompensation, Profile Management • PeopleSoft ELM for Cognizant Academy • User base – 180K , World wide • Database size : ESA – 2 .5 TB, HCM – 1 TB, ELM – 800 GB • Peak user load: ESA – 15K bi-weekly, HCM – 40K semi-annually, ELM – 10K (irregular peaks)

  42. Architecture Technology Components Deployment for 3 Applications (Financials, HCM, ELM) Primary: App Tier: ½ Rack Exalogic DB Tier: ¼ Rack Exadata (High Performance) Stand by: App Tier: 1/8th Exalogic DB Tier: ½ Rack Exadata (High capacity) Applications: PS HCM 9.1, PS Financials 9.1, PS ELM 9.1 Environment Management Oracle EM for PeopleSoft Applications Monitoring for Health & Perf: Oracle EM for PeopleSoft and Oracle Real User Experience (RUEI)

  43. Maximum Availability Architecture: PeopleSoft Deployment at Cognizant SLA: 99.9% uptime

  44. Maximum Availability at Cognizant

  45.
