IBM® Fault Analyzer for z/OS provides numerous technology and business benefits:
It gathers information about an application and the surrounding environment at the time of an abnormal end (abend), providing you with the valuable information you need to develop and test your applications.
Because it only runs when your application fails, it saves your processing resources for other tasks when your application is operating normally.
There is no need to recompile programs or change the job control language because Fault Analysis starts automatically when an application fails.
Error messages and codes that apply to your failure are easy to understand.
After analyzing information about your application and its environment, it generates an analysis report that describes the problem in terms of application codes so that you are not forced to interpret a low-level system dump or system-level error messages. The reason for the abend is made available to you sooner and with less effort.
