It records many system events, with minimal detail about each. The events traced are predetermined, except for branch tracing. This trace uses fewer resources and is faster than a GTF trace.
System trace tables reside in fixed storage on each processor. The default trace table size is 64 kilobytes per processor, but you can change it using the TRACE ST command. We do not recommend running with trace tables smaller than the default 64 kilobytes. You might, however, want to increase the size of the system trace table from the default 64 kilobyte when:
