<p>The Start Communications Trace (STRCMNTRC) command initiates a communications trace for a specified line, a network interface or a network server description.
</p>
<p>A communications trace continues until:
</p>
<ul>
<li>The End Communications Trace (ENDCMNTRC) command is run.
</li>
<li>The Communications Trace function of the Start System Service Tools (STRSST) command is used to end the trace.
</li>
<li>A physical line problem causes the trace to end.
</li>
<li>TRCFULL(*STOPTRC) is specified and the buffer becomes full.
</li>
<li>Automatically by the watch for trace event functionality.
</li>
</ul>
<p><b>Restrictions:</b>
</p>
<ul>
<li>The user must have *USE authority to the line, network interface, or network server to be traced.
</li>
<li>To use this command, you must have service (*SERVICE) special authority, or be authorized to the Service Trace function of Operating System through iSeries Navigator's Application Administration support. The Change Function Usage (CHGFCNUSG) command, with a function ID of QIBM_SERVICE_TRACE, can also be used to change the list of users that are allowed to perform trace operations.
</li>
<li>The following user profiles have authority to this command:
<ul>
<li>QSECOFR
</li>
<li>QSRV
</li>
</ul>
</li>
<li>When the <b>Watched job (WCHJOB)</b> parameter is specified, the issuer of the command must be running under a user profile which is the same as the job user identity of the job being watched, or the issuer of the command must be running under a user profile which has job control (*JOBCTL) special authority. Job control (*JOBCTL) special authority is also required if a generic user name is specified for the WCHJOB parameter.
</li>
<li>If you specify a generic user name in the WCHJOB parameter, you must have all object (*ALLOBJ) special authority, or be authorized to the Watch Any Job function of Operating System through iSeries Navigator's Application Administration support. The Change Function Usage (CHGFCNUSG) command, with a function ID of QIBM_WATCH_ANY_JOB, can also be used to change the list of users that are allowed to start and end watch operations.
</li>
<li>You must have operational (*OBJOPR) and execute (*EXECUTE) authorities to the user exit program if specified in <b>Trace program (TRCPGM)</b> parameter, and execute (*EXECUTE) authority to the library where the program is located.
</li>
<li>You must have use (*USE) authority to the message queues specified in <b>Watched message queue (WCHMSGQ)</b> parameter, and use (*USE) authority to the library where the message queue is located.
</li>
</ul>

<h3>Watch for LIC log entry (WCHLICLOG)</h3>
<p>Specifies up to five licensed internal code (LIC) log entry identifiers which are to be watched for. Each LIC log entry contains a major and a minor code. The watched for condition will be met if a LIC log entry is added that matches the specified major and minor codes and any comparison data specified. When the watched for log entry is added to the LIC log, the trace exit program is called, even when the comparison data specified does not match; if no trace exit program is defined, the trace stops.

</dd>
<dt><b><i>character-value</i></b></dt>
<dd>Specify the LIC log major code to be watched for. You can specify either a hexadecimal digit or a question mark for each character in the four-digit code. A question mark is a wildcard character that will match any digit in that position. Up to three wildcard characters can be specified.
</dd>
</dl>
<p><b>Element 2: Minor code</b>
</p>
<dl>
<dt><b>*ALL</b></dt>
<dd>Any LIC log entry minor code will be considered to be a match. If *ALL is specified for the minor code, you cannot specify *ALL for the LIC log entry major code.
</dd>
<dt><b><i>character-value</i></b></dt>
<dd>Specify the LIC log minor code to be watched for. You can specify either a hexadecimal digit or a question mark for each character in the four-digit code. A question mark is a wildcard character that will match any digit in that position. Up to three wildcard characters can be specified.
</dd>
</dl>
<p><b>Element 3: Comparison data</b>
</p>
<p>Specify comparison data to be used if a log entry matching the specified major and minor codes is added to the licensed internal code (LIC) log. If this text is found in the LIC log entry data fields of the watched for log entry, the watched for condition is true. If this text is not found in the LIC log entry data fields of the watched for log entry and no exit program is specified on the TRCPGM parameter, the trace function continues. If the log entry matches the specified major and minor codes and an exit program is specified on the TRCPGM parameter, but the entry data does not contain the specified text, the exit program is called to determine if the trace should continue or stop.
</p>
<dl>
<dt><b><u>*NONE</u></b></dt>
<dd>No comparison data is specified. If a LIC log entry matching the specified major and minor codes is added to the LIC log, the watched for condition is true.
</dd>
<dt><b><i>character-value</i></b></dt>
<dd>Specify the text string used to compare against the entry data of the watched for log entry. If this text is found in the LIC log entry data fields compared of a watched for log entry, the watch condition is considered to be true. This text is case sensitive. The LIC log fields which can be compared are TDE number, task name, server type, job name, user ID, job number, thread ID, exception ID, LIC module compile timestamp, LIC module offset, LIC module RU name, LIC module name, LIC module entry point name. The comparison data cannot be used to match across two fields, and can match an entire field or a substring of any field.
<p>When watching for an exception ID, all four hexadecimal digits of the exception ID must be specified. Also, the prefix MCH may be specified if you want to compare only against the exception ID field and avoid possible substring matches with the other fields.
