Privilege Classes: A, B, C, E
Use QUERY TRACEFRAMES to display the number of pages that are set aside for
an internal trace table for the master processor and the alternate processors in the
configuration.
1. CP maintains separate internal trace tables for each processor in the
configuration. The QUERY TRACEFRAMES command displays the number of
trace frames in the internal trace table of the master processor and the size of
the internal trace tables of the alternate processors. The size of the internal
trace table of an alternate processor is expressed as a percentage of the
master processor’s trace table.
2. Use the SET TRACEFRAMES command to change the size of the internal trace
tables. For more information, see “SET TRACEFRAMES” on page 1412.
3. See “QUERY FRAMES” on page 804 for information on the current usage of
real storage, including trace frames.
Response 1:
If the response to a QUERY TRACEFRAMES command were:
Master processor trace frames = 100
Alternate processor trace frames = 90 percent of master
and you had a 4-processor CPU, the master processor would have a 100-page
internal trace table; and each of the three alternate processors would have 90-page
internal trace tables.
