The RACROUTE call may not be captured (traced) because the abend occurred during the RACROUTE processing. The default TRACEing option is POST|AFTER security validation processing occurred. You can change the TRACE option to PRE|BEFORE or ALL so the RACROUTE call can be captured (traced) prior to security validation processing occurring.
The ACF2 SECTRACE operator command includes a TRACE operand which controls whether to capture(trace) RACROUTE calls prior to or after security validation processing occurs. The syntax is as follows:
nn CAS21200 SPECIFY RACROUTE PARAMETERS, CANCEL OR END
nn CAS21100 CONTINUE SECTRACE SPECIFICATIONS, CANCEL, OR END
CAS21110 SECTRACE SET ON mm.ddd hh:mm:ss ID=TEST
