address of the start of the trace table, TRACSTRT, is at location X'OC'. The
address of the byte following the end of the trace table, TRACEND, isat location X'10'. And the address of the next available trace table entry, TRACCURR, is at
location X'14'. Subtract 16 bytes(X'10') from the address stored at X'14'
(TRACCURR) to obtain the trace table entry for the last event completed.
TheCP internal trace table is initialized during IPL. If you do not wish to record
events in the trace table, issue theMONITOR STOP command to suppress recordĀ
ing. iref refid=debugm. The pages allocated to the trace table are not released
and recording can berestarted at any time by issuing the MONITOR START
command. If the VM/SP system should abnormally terminate and automatically
restart, the tracing of events on the real machine will be active. After aVM/SP IPL (manual or automatic), CP internal tracing is always active.
