|
|
|
|
<blockquote>
|
|
<p>A batch job might have one or more holds, which prevent the batch job from executing. A batch job from which all the holds have
|
|
been removed becomes eligible for execution and is said to have been released. A batch job hold is removed by sending a request to
|
|
the batch server that manages the batch job. The <i>qrls</i> utility is a user-accessible client of batch services that requests
|
|
holds be removed from one or more batch jobs.</p>
|
|
|
|
<p>The <i>qrls</i> utility shall remove one or more holds from those batch jobs for which a batch <i>job_identifier</i> is
|
|
presented to the utility.</p>
|
|
|
|
<p>The <i>qrls</i> utility shall remove holds from batch jobs in the order in which their batch <i>job_identifier</i>s are
|
|
presented to the utility.</p>
|
|
|
|
<p>If the <i>qrls</i> utility fails to process a batch <i>job_identifier</i> successfully, the utility shall proceed to process the
|
|
remaining batch <i>job_identifier</i>s, if any.</p>
|
|
|
|
<p>The <i>qrls</i> utility shall remove holds on each batch job by sending a <i>Release Job Request</i> to the batch server that
|
|
manages the batch job.</p>
|
|
|
|
<p>The <i>qrls</i> utility shall not exit until the holds have been removed from the batch job corresponding to each successfully
|
|
processed batch <i>job_identifier</i>.</p>
|
|

|
|
|
|
<h4><a name="tag_04_112_04"></a>OPTIONS</h4>
|
|
|
|
<blockquote>
|
|
<p>The <i>qrls</i> utility shall conform to the Base Definitions volume of IEEE Std 1003.1-2001, <a href=
|
|
"../basedefs/xbd_chap12.html#tag_12_02">Section 12.2, Utility Syntax Guidelines</a>.</p>
|
|
|
|
<p>The following option shall be supported by the implementation:</p>
|
|
|
|
<dl compact>
|
|
<dt><b>-h </b> <i>hold_list</i></dt>
|
|
|
|
<dd>Define the types of holds to be removed from the batch job.
|
|
|
|
<p>The <i>qrls</i> <b>-h</b> option shall accept a value for the <i>hold_list</i> option-argument that is a string of alphanumeric
|
|
characters in the portable character set (see the Base Definitions volume of IEEE Std 1003.1-2001, <a href=
|
|
"../basedefs/xbd_chap06.html#tag_06_01">Section 6.1, Portable Character Set</a>).</p>
|
|
|
|
<p>The <i>qrls</i> utility shall accept a value for the <i>hold_list</i> option-argument that is a string of one or more of the
|
|
characters <tt>'u'</tt> , <tt>'s'</tt> , or <tt>'o'</tt> , or the single character <tt>'n'</tt> .</p>
|
|
|
|
<p>For each unique character in the <i>hold_list</i> option-argument, the <i>qrls</i> utility shall add a value to the
|
|
<i>Hold_Types</i> attribute of the batch job as follows, each representing a different hold type:</p>
|
|
|
|
<dl compact>
|
|
<dt><tt>u</tt></dt>
|
|
|
|
<dd>USER</dd>
|
|
|
|
<dt><tt>s</tt></dt>
|
|
|
|
<dd>SYSTEM</dd>
|
|
|
|
<dt><tt>o</tt></dt>
|
|
|
|
<dd>OPERATOR</dd>
|
|
</dl>
|
|
|
|
<p>If any of these characters are duplicated in the <i>hold_list</i> option-argument, the duplicates shall be ignored.</p>
|
|
|
|
<p>An existing <i>Hold_Types</i> attribute can be cleared by the following hold type:</p>
|
|
|
|
<dl compact>
|
|
<dt><tt>n</tt></dt>
|
|
|
|
<dd>NO_HOLD</dd>
|
|
</dl>
|
|
|
|
<p>The <i>qrls</i> utility shall consider it an error if any hold type other than <tt>'n'</tt> is combined with hold type
|
|
<tt>'n'</tt> .</p>
|
|
|
|
<p>Strictly conforming applications shall not repeat any of the characters <tt>'u'</tt> , <tt>'s'</tt> , <tt>'o'</tt> , or
|
|
<tt>'n'</tt> within the <i>hold_list</i> option-argument. The <i>qrls</i> utility shall permit the repetition of characters, but
|
|
shall not assign additional meaning to the repeated characters.</p>
|
|
|
|
<p>An implementation may define other hold types. The conformance document for an implementation shall describe any additional hold
|
|
types, how they are specified, their internal behavior, and how they affect the behavior of the utility.</p>
|
|
|
|
<p>If the <b>-h</b> option is not presented to the <i>qrls</i> utility, the implementation shall remove the USER hold in the
|
|
<i>Hold_Types</i> attribute.</p>

<h4><a name="tag_04_112_18"></a>RATIONALE</h4>
|
|
|
|
<blockquote>
|
|
<p>The <i>qrls</i> utility allows users, operators, and administrators to remove holds from jobs.</p>
|
|
|
|
<p>The <i>qrls</i> utility does not support any job selection options or wildcard arguments. Users may acquire a list of jobs
|
|
selected by attributes using the <a href="../utilities/qselect.html"><i>qselect</i></a> utility. For example, a user could select
|
|
all of their held jobs.</p>
|
|
|
|
<p>The <b>-h</b> option allows the user to specify the type of hold that is to be removed. This option allows for USER, SYSTEM,
|
|
OPERATOR, and implementation-defined hold types. The batch server that manages the batch job will verify whether the user is
|
|
authorized to remove the specified hold for the batch job. If more than one type of hold has been placed on the batch job, a user
|
|
may wish to remove only some of them.</p>
|
|
|
|
<p>Mail is not required on release because the administrator has the tools and libraries to build this option if required.</p>
|
|
|
|
<p>The <i>qrls</i> utility is a new utility <i>vis-a-vis</i> existing practice; it has been defined in this volume of
|
|
IEEE Std 1003.1-2001 as the natural complement to the <a href="../utilities/qhold.html"><i>qhold</i></a> utility.</p>
