1. Introduction Optimizing Application Performance with Pinpoint Accuracy What every IT Executive, Administrator & Developer Needs to Know

2. Benefits Get more from your BUDGET Get more from your STAFF Get more from your APPLICATIONS

3. Top-Down Approach DISCOVER when issues occur LEARN where issues exist FOCUS on root causes SOLVE the right problems

4. Executive Management Get more from your BUDGET Focus your staff on fixing root-cause performance issues rather than just visible symptoms. Understand costs and benefits of hardware upgrades versus better systems management, database tuning and application performance enhancements. Save critical IT resources to improve your bottom line and increase customer satisfaction.

5. Focus on Root-Cause Focus your staff on fixing root-cause performance issues rather than just visible symptoms. Most performance issues are due to applications performing unnecessary and excessive I/O. Response time issues, high CPU use, memory faulting, high disk activity, long running batch jobs and slow Client/Server and web requests are usually symptoms of inefficient application I/O. Focus on the “area under the curve” rather than chasing “spikes”.

6. Understand Costs & Benefits Understand costs and benefits of hardware upgrades versus better systems management, database tuning and application performance enhancements. Focus on the 80/20 rule - if 80% of system resources are consumed by 20% of your applications, fix the applications; otherwise upgrade the hardware. Better systems management and database tuning can provide significant savings, even with purchased software and no source code. With source code, enhance for performance!

7. Save Critical Resources Save critical IT resources to improve your bottom line and increase customer satisfaction. Less time chasing performance issues means more time to develop new applications and functionality for end-users. Hardware upgrades may be the traditional, quick, easy answer but it’s seldom the most cost effective and best solution for the bottom line. Satisfied customers are those with needed application functionality and responsiveness.

8. Systems Administration Get more from your STAFF Focus on proactive performance monitoring and analysis; avoid reacting to latest critical complaint. Analyze historical systems management and performance analysis data and focus on root- cause issues rather than visible symptoms. Use a top-down approach to identify and resolve critical systems management, database tuning and application performance issues.

9. Proactive Monitoring & Analysis Focus on proactive performance monitoring and analysis; avoid reacting to latest critical complaint. Random CPU spikes and response time issues are difficult to catch, analyze and resolve – focus on the “area under the curve” and reduce overall utilization so “spikes” don’t matter. The job or program putting utilization over the edge and causing the short “capacity issue” is not the “root-cause” – focus on the underlying root- cause issues.

10. Analyze Historical Data Analyze historical systems management and performance analysis data and focus on root-cause issues rather than visible symptoms. SQL performing the same “full-table scan” or “temporary access path rebuild” 3,000 times per day causes the “area under the curve” to be 20% higher than normal, all day, every day. 250,000 jobs per week submitted to batch called “CLOSEORDER” is not the most efficient. Date routines doing a “SETON LR” 30,000 times per hour interactively could use improvement.

11. Use Top-Down Approach Use a top-down approach to identify and resolve critical systems management, database tuning and application performance issues. If specific jobs are consistently causing performance or capacity issues, start at the job level and drill-down into the data – find databases, programs, modules, procedures and lines of source code responsible for the high-level issues. Basic configuration, tuning and/or code changes can solve major operational issues that more hardware wouldn’t even resolve.

12. Software Development Get more from your APPLICATIONS Focus on root causes of application performance issues rather than just visible symptoms. Spend your time fixing, testing and implementing application and database performance issues rather than searching for the root-cause. Improve the quality and responsiveness of applications for end users through properly performing applications.

13. Focus on Root-Cause Focus on root causes of application performance issues rather than just visible symptoms. It may be time to replace that old CVTDATE command and programs with newer, more efficient techniques that “stay in memory”. The CALCTAX program may be called by many other programs, it would be nice to have it “leave it’s files open”. A simple data queue server job might be the technique to cut the jobs on your system by 90%.

14. Spend Time Implementing Spend your time fixing, testing and implementing application and database performance issues rather than searching for the root-cause. Analyzing CPU, I/O or elapsed time by job, program, module, procedure and line of source code can significantly reduce your time spent finding the root-cause issues. Determining that 3 billion records are being read by SQL every day to select 25,000 records can focus you on database tuning opportunities.

15. Increase Customer Satisfaction Improve the quality and responsiveness of applications for end users through properly performing applications. The best quality applications in the world are “useless” if they are not responsive and don’t meet the performance needs of the end users and customers. Applications rarely need to be completely re- written – there are usually very simple, basic systems management, database tuning or application code changes that can be made.

16. Summary Optimizing Application Performance with Pinpoint Accuracy What every IT Executive, Administrator & Developer Needs to Know Hardware upgrades are seldom the most cost effective solution to performance issues and they may not solve the root-cause issues (e.g. CPU doesn’t relieve I/O bottlenecks). Systems management and database tuning changes can be made even without source code; with source code, enhance for performance. Focus on “area under curve”; be proactive; analyze and learn from historical data; streamline applications when appropriate.
