3 abstract Steve SeaneyJosh Leone Large Global BankCA Technologies, Inc. Sr. Mgr Business SystemsDir. Engineering Services Over the past 15 months, a large global bank has worked closely with CA and our internal support teams to improve the response of our global CA Clarity PPM instance. Through the efforts, the bank has delivered a 400% improvement in CA Clarity PPM response without significant infrastructure investments. As a result, CA Clarity PPM has become a strong and viable solution for a variety of business problems facing the bank. The presentation will include a review of our approach, a discussion of changes implemented, and an outline of our current path forward 3

4 4 CA Clarity PPM at the large global bank Performance – then and now Roadmap to improvement Key drivers for performance improvement Ongoing maintenance Q&A agenda

5 The bank hosts a large and active CA Clarity installation 5 35,000 active users Time, project management, & resource management Extensively global user base 30,000 timesheets & 2000 reports per week Highly secure environment Substantial hardware hosts CA Clarity PPM Unix based database and application servers Oracle 10g 3-node RAC database environment IBM WebSphere V7 (64bit) application environment CA Clarity PPM with OWB and CABI

6 Performance measurement & criteria 6 Synthetic transaction time monitored Production environment 30 separate transactions from 5 global locations Logon, project list page, populate timesheet 10 minute cycle Performance success criteria: Original: 90% of transactions completed in 5 seconds Current: 90% of transactions completed in 3 seconds

7 Massive performance improvement Slow response 40% transactions > 6 secs Daily heap dumps Critical long running sessions Frequent crisis calls Disabled key functionality Reports & portlets disabled Advance functionality (RM) Loud user complaints Fast response 95% transactions > 3 secs Heap dumps have stopped Occasional long running sessions Low priority incidents Full functionality enabled Reports & portlets enabled Resource management deployment Spot issues (particular report) February 2010October
