If the probe is coded as a minidump, an FFST™ minidump is written to the output data set. See Figure 1.
An FFST minidump contains general-purpose registers, and selected VTAM® control blocks. When an FFST minidump is triggered, an additional dump providing the last 4 MB of the 64-bit common VIT table is also generated by using the system SDUMPX macroinstruction. If the VIT table is larger than 4 MB, the dump contains the VIT table header with the last 4 MB of the VIT.
The probe output data used for VTAM FFST minidumps are found in the data sets that were allocated when VTAM FFST was installed.
