<p>The Trace Intersystems Communications Functions (TRCICF) command is used to start and stop the tracing of language operations and Intersystem Communications Functions (ICF) issued by your program. TRCICF can be started from the command entry display or from a CL program.
|
||
|
|
</p>
|
||
|
|
<p>As trace records are collected, they are stored in an internal trace storage area. When the trace is ended, the trace records can be directed to a spooled output file or a database physical file.
|
||
|
|
</p>
|
||
|
|
<p>If the Start Service Job (STRSRVJOB) command is entered before the TRCICF command, the job that is traced is the one specified on the STRSRVJOB command. The trace output from the serviced job is returned to the servicing job after the trace is set off or after the serviced job has ended.
