<p>The Control Trace (QWTCTLTR) API turns the early trace function on and off.
|
||
|
|
The value of *ON is passed to the program to turn the early tracing on, and
|
||
|
|
*OFF is passed to turn the early tracing off.</p>
|
||
|
|
|
||
|
|
<p>When the early trace function is turned on, the jobs that are set up by the
|
||
|
|
Set Trace (QWTSETTR) API begin tracing as soon as they are started. The tracing
|
||
|
|
is stopped by turning it off with the Control Trace (QWTCTLTR) API. When *OFF
|
||
|
|
or *RESET is passed to the program, this causes the trace information for the
|
||
|
|
jobs to dump to spooled files.</p>
|
||
|
|
|
||
|
|
<p>The information set up by this API remains in effect during an initial
|
||
|
|
program load (IPL).</p>
|
||
|
|
|
||
|
|
<p>This API should be used only when recommended by your IBM service
|
||
|
|
representative.</p>
