DFHTRPX

DFHTRPX provides a fast path for the processing of trace-put requests. While DFHTRPX belongs to the trace domain, it may be invoked without incurring the overhead of a normal domain call; DFHTRPX runs as a subroutine of the domain requesting the trace. Most trace-put requests are handled by DFHTRPX.

The amount of CPU consumed by DFHTRPX can be reduced by selectively limiting the scope of your CICS trace options.
