<p>The Trace Common Programming Interface Communications (TRCCPIC) command controls tracing of all CPI Communications that occur in the job in which the command is entered. The command sets a trace on or off, and traces (1) CPI Communications calls issued by a program and (2) data that is sent and received.
|
||
|
|
</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 TRCCPIC 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.
|
||
|
|
</p>
|
||
|
|
<p><b>Restrictions:</b> (1) The record format of the database output file must match the record format of the IBM-supplied output file, QACM0TRC. (2) The user must have specific authority from the security officer to use this command.
