First Failure Support Technology™ is a licensed program that captures information about a potential problem when it occurs. See z/OS Information Roadmap to determine what document contains more information about FFST™.
When a problem is detected, a software probe is triggered by VTAM®. FFST then collects information about the problem and generates output to help solve the problem. Based on the options active for the probe, you get a dump and a generic alert. See The generic alert for information about generic alerts. You also get the FFST EPW message group as shown in the FFST console.
