Sr. Mgr Business Systems Dir. 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

The bank hosts a large and active CA Clarity installation

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 12.1.0 with OWB and CABI

Performance measurement & criteria

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
