Front-end to PEX and Trace

In rare cases - most installations will probably never get the need - complex performance problems may require a more detailed analysis than what GiAPA can offer as standard. Typical cases are when jobs are delayed without using very much CPU - such jobs are normally assumed to be OK by GiAPA, but may be analyzed using GiAPA's own "Watch job" function.

             

Should that not be sufficient, GiAPA includes interfaces to IBM's PEX (Performance Explorer) tool and to the CL-commands used to trace a job. Whilst these two tools master an extremely detailed analysis of what a job or programs does, the resulting standard reports can be very large and somewhat complex, and therefore present a "needle in the haystack" situation.

           

GiAPA's front ends to PEX and Trace Job make it very easy to use these IBM tools, because GiAPA will analyze the results automatically and produce exception reports, which e.g. for a trace analysis could be a couple pages in stead of several hundred.

 

Why GiAPA if we have IBM PEX ?

An often heard question is "IBM offers several excellent tools to analyze performance - so why consider GiAPA?"

The short answer is that there of course is some overlap between the IBM tools and GiAPA, but

  • The IBM tools are normally only used for "fire extinguishing", i.e. being used targeted against one job or program after a problem/delay has been experienced.
  • In contrast, GiAPA will allow you a pro-active approach, automatically collecting and analyzing data for all jobs all the time, allowing you to react on inefficiencies before they ever become a problem.

GiAPA's ingenious combination of using very little resources, but still collecting sufficient data for detailed performance analysis, together with the fully automatic analysis resulting in easy-to-understand exception reports, has for most GiAPA installations resulted in significant performance improvements even within applications believed to run efficiently.

A very important GiAPA side benefit is the comprehensive data base documenting all use of resources - a true gold mine for operations' every day control of server usage, and reporting to management.
