The document discusses Rose International's Database Performance Optimization Practice (DPOP). It describes how DPOP was established to help optimize customer databases and increase value. The DPOP team has skills and tools to establish database performance best practices. Recent case studies show DPOP achieving significant performance gains of over 90% for clients like Centene Corporation and Express Scripts through optimizations that reduce CPU usage, response time, and I/O. DPOP engagement involves an initial analysis with no cost and guaranteed minimum 50% performance improvement.

1. Database Performance Optimization Practice Framework
Database Performance Optimization Practice (DPOP) History at Rose:
Rose International noticed powerful opportunities to tune and greatly enhance customer databases
during the course of providing solution services to State, Federal and Commercial customers. As such,
Rose began a search for tools to help our solution teams increase their value to the customer base.
Through the course of such exploration, we determined that this area could support a separate practice.
The Rose International DPOP Team:
"I would like to say thank you for

Jack Henry & Associates another aspect of incorporating this DPOP practice into
your organization.
How to Engage DPOP:
Two to four hours of actual time (elapsed time may be longer, as tools run on your database) is required
for an initial analysis of key mission critical, high volume transactions. There is no cost for this
analysis. At the end of the analysis, we will provide a report indicating the number of additional hours
and the estimated improvement in CPU Utilization and Response Time that can be expected for those
transactions.
No matter the expectation set in our report, if we do not generate at least a 50 percent
improvement in either CPU Utilization or Response Time, you pay nothing to Rose International.
Also, in the event that one of our DPOP solutions reverts back to prior performance, our DPOP Team
will fix this at no cost. While this has never happened, we still offer this as a further guarantee of our
DPOP service. Rest assured from the initial analysis to after the solution is implemented; Rose
International's DPOP Team will be there to provide the necessary support.

2. Recent Gains Summary of DPOP:
Centene Corporation (January 2009 - July 2009)
Recent engagement spanned six months across various adjudication, data warehouse
and operational data store (ODS) applications. Over 100 performance tuning efforts
were authored via DPOP, and the average gains in CPU reduction and elapsed time
reduction were over 90 percent.
Below are just a few gains of actual performance gains realized via DPOP at Centene
Corporation. Again, there were over 100 efforts with gains similar to the below
percentage improvements.

Express Scripts (August 2009 - Present)
The Rose International DPOP Team is currently engaged at Express Scripts. One
example of the Rose DPOP Team's results is that the most expensive SQL in Express
Scripts' member portal system has had its CPU consumption and elapsed time reduced
by over 95 percent. The original number of logical reads for this SQL was over two billion
per day, and is now a few thousand.
Further results of the Rose DPOP Team's tuning analysis are listed below. Based on just
these gains, there has been over three billion I/O's saved per day, which resulted in 500
hours of daily CPU usage reduction, and over 1,000 hours of daily Elapsed Time
reduction.
