Brief Description


GiAPA is an acronym of the words describing the aim of the software product:

Global iSeries Application Performance Analyzer


The main goal of GiAPA is to hide all the complex data collection and analysis in the program logic to enable any programmer and operator to automatically pinpoint performance issues.


In addition, with detailed data for all jobs and tasks available every 15 seconds, the GiAPA data base has become an unprecedented tool for operations being responsible for controlling use of resources and producing usage information and trend reports to management.


Apart from the above basic functions of GiAPA there are quite a number of additional features including additional performance investigations, analysis of data base files, data import/export and housekeeping.

GiAPA basically works in 3 steps:


Data Collection:

Runs in batch typically using less than 0.1 % of one CPU allowing data collection 24/7 and the data is stored in a compressed binary format using minimum disk space.

Complete attributes and use of 22 types of resources are received for all active jobs from operating system APIs every 15 seconds. This data is processed real-time.

If a job within a 15 seconds collection interval is using excessive resources indicating that it might have or cause a performance problem, GiAPA also retrieves data for all open files and the program call stack.


Expansion and Analysis

GiAPA runs in a batch job creating a number of data base file members containing the results to be used as input for the numerous exception reports and charts. Data for a day, an hour, or a whole week, etc. may be selected. Can be scheduled to run e.g. every night, or requested interactively if e.g. a recent incident should be analyzed immediately.

Data from jobs suffering from or potentially causing performance problems are stored individually by GiAPA for further analysis. Data for other jobs or tasks are kept summarized by type and interval, unless all details explicitly are requested.

All data analysis is performed in a manner transparent to the user. Installation parameters control the limits for when detailed data should be kept


Reports for Management , Operations and Development

After expansion and analysis GiAPA will display or you can print a large number reports and graphics that can be requested interactively. The output can be summarized in many levels, or shown very detailed down to job-id per 15 seconds, combined with extensive selection and sort options. Details for jobs that used any significant amount of resources are automatically stored and detailed performance analysis requires only few keystrokes rather than expensive external assistance. The results are available as traditional reports including all needed details, but can within seconds be converted to charts.

Industry News

Introducing a revolutionary new iSeries Application Performance tool that can save you a lot of time, resources and money!

GiAPA is designed to increase the speed at which applications run on your system which will cause you to spend less time waiting on applications to generate the reports you need. GiAPA can reduce the amount of CPU usage needed to run those applications causing you to use fewer resources to accomplish the same ends. Ultimately GiAPA empowers you to do more with less and eliminate or delay the need to purchase additional system resources or upgrades.

GiAPA monitors your system usage 24/7 and collects detailed data to pinpoint unique events such as when an application:

1. slows down for no apparent reason 

2. demands higher than expected CPU usage.


These events are reported in a concise and easy to follow format explaining the exact cause of each and how best to correct it.

GiAPA does this in the background using minimal resources and will continue to monitor and report any new issues that crop up with upgrades, applications or even new users.

If GiAPA's cost exceeded it's benefits then we would never be able to interest anyone in even trying GiAPA.
But GiAPA's track record (Return-on-Investment) is well documented by those that are already using GiAPA.
