通知屏幕用来通知 DB2 在任务完成时将完成代码发送到哪里。这不会发送任务的实际结果，而只是发送返回码。
</p>
<img alt="任务 — 通知" src="images/db2cert7013-task-notification.gif"><p>
可以为单个任务发送多个通知。这些通知可以基于：</p>
<ul>
<li>
<b>任务成功：</b>在任务顺利完成时，发送该通知。</li>
<li>
<b>任务失败：</b>当任务未能顺利完成时，发送该通知。</li>
<li>
<b>任何条件：</b>无论结果如何，都发送该通知。</li>
</ul>
<p>
除了通知级别之外，还可以指定发送通知的方式。任务中心可以通知联系人或将信息放置到日志（Journal）（请参阅<a href="db2cert7013-2-15.html">日志</a>）中。联系人名单包括一组用户，您可以向他们发送寻呼机通知或电子邮件通知。
</p>
<img alt="任务 — 联系" src="images/db2cert7013-task-contacts.gif"><p>
注：如果想把消息发送给用户，则必须在机器上设置 SMTP 服务器。没有这种功能，就无法发送消息。
</p>
<p>
可以定制消息本身，以包含您希望包含的任何文本。在文本中可以使用许多符号变量（用于返回关于任务的信息）：
</p>
<ul>
<li>
<b>&Categories：</b>与任务关联的类别。</li>
<li>
<b>&Completionstatus：</b>任务的完成状态。这个值取决于与任务相关联的成功代码集。
</li>
<li>
<b>&Description：</b>任务的描述。</li>
<li>
<b>&Duration：</b>运行系统完成任务的全过程所花费的时间。</li>
<li>
<b>&End：</b>完成任务的日期和时间。</li>
<li>
<b>&Howinvoked：</b>用来调用任务的方法。</li>
<li>
<b>&Name：</b>任务的名称。</li>
<li>
<b>&Owner：</b>任务的拥有者的名称。</li>
<li>
<b>&Returncode：</b>任务的最终返回码。</li>
<li>
<b>&Runpartitions：</b>任务运行所在的分区。</li>
<li>
<b>&Runsystem：</b>任务运行所在系统的名称。</li>
<li>
<b>&Schedulersystem：</b>调度任务所在系统的名称。</li>
<li>
<b>&Start：</b>任务开始运行的日期和时间。</li>
<li>
<b>&Type：</b>任务类型（即，它是 DB2 脚本、OS 脚本、MVS shell 脚本、JCL 脚本还是分组任务）。</li>
<li>
<b>&Userid：</b>任务的用户标识。</li>
</ul>
