DBRC trace output

Trace output normally resides in subpool 0 storage, but you can direct output to a Generalized Trace Facility (GTF) data set.

The DBRC internal trace is a wraparound trace. That is, after the trace table is full, tracing starts at the beginning of the table, and each new entry overlays an old entry.

An entry with the identifier TRACENXT marks the next entry to be used, which is the logical end of the trace table.
