GiAPA

Global iSeries Application Performance Analysis

iSeries professionals consider application performance optimization a complex task, normally requiring expensive external experts. However, GiAPA's automatic data collection and analysis makes it easy for the average operator, programmer or systems analyst to locate and diagnose the vast majority of performance inefficiencies.

GiAPA assists in locating and diagnosing performance inefficiencies in applications running under i5/OS. GiAPA will assist you in using your existing computer resources in an optimal way, without the need to purchase additional hardware to meet the growth of users or applications.

Using less than 0.1 percent of one CPU, GiAPA collects performance data for all active jobs and tasks, automatically storing additional details down to thread level for the jobs using the most resources.

GiAPA allows you to collect comprehensive performance data continuously at merely no cost. This means that when a performance problem has occurred (e.g. a user complains about bad response times during the morning), you can pinpoint the cause within the available GiAPA data.

GiAPA is designed to tell you:

• which of your applications have performance problems,
• what the problems are,
• within which program(s), often down to source statement line number, and
• how the application can be improved to run efficiently.

GiAPA is used for much more than speeding up applications

Other Benefits:

• keep track of who runs which programs and when
• analyze any performance problems even after they happened
• create graphics allowing management to follow trends in resource usage by application, by user, by hour, week, etc...
• assist operations in the daily control of machine usage
• use as base for simple job accounting
• solve certain complex capacity planning
• control quality of new applications before they go in production
