<h1 class="topictitle1">Send messages to a system user</h1>
|
||
|
|
<div><p>Several commands can be used to send messages to system users.</p>
|
||
|
|
<div class="section"> <p> </p>
|
||
|
|
<ul><li><span class="cmdname">Send Message (SNDMSG)</span></li>
|
||
|
|
<li><span class="cmdname">Send Break Message (SNDBRKMSG)</span></li>
|
||
|
|
<li><span class="cmdname">Send Program Message (SNDPGMMSG)</span></li>
|
||
|
|
<li><span class="cmdname">Send User Message (SNDUSRMSG)</span></li>
|
||
|
|
</ul>
|
||
|
|
<p><span class="cmdname">Send Program Message (SNDPGMMSG)</span> and <span class="cmdname">Send
|
||
|
|
User Message (SNDUSRMSG)</span> can only be used in batch or interactive
|
||
|
|
OPM programs or ILE procedures. These commands cannot be entered on a command
|
||
|
|
line. The <span class="cmdname">Send Message (SNDMSG)</span> command sends an informational
|
||
|
|
or inquiry message to the system operator message queue (QSYSOPR), a display
|
||
|
|
station message queue, or a user message queue. You can send an informational
|
||
|
|
message to more than one message queue at a time. But you can send an inquiry
|
||
|
|
message to only one message queue at a time. The message is delivered by
|
||
|
|
the delivery type specified for the message queue. The message does not interrupt
|
||
|
|
the user unless the message queue is in break mode.</p>
|
||
|
|
<p>The following <span class="cmdname">Send
|
||
|
|
Message (SNDMSG)</span> command is sent by a display station user to the
|
||
|
|
system operator: </p>
|
||
|
|
<pre>SNDMSG MSG('Mount tape on device TAP1') TOUSR(*SYSOPR)</pre>
|
||
|
|
<p>The <span class="cmdname">Send Break Message (SNDBRKMSG)</span> command
|
||
|
|
sends an immediate message from a workstation, a program, or a job to one
|
||
|
|
or more display stations to be delivered in the break mode regardless of what
|
||
|
|
delivery mode the receiver's message queue is set to. This command can be
|
||
|
|
used to send a message only to display station message queues. You should
|
||
|
|
use the <span class="cmdname">Send Break Message (SNDBRKMSG)</span> command when sending
|
||
|
|
any message that requires the immediate attention of a display station user.
|
||
|
|
You cannot ensure the message will cause a break, because each job has control
|
||
|
|
by using the BRKMSG parameter on the <span class="cmdname">Change Job (CHGJOB)</span> command.</p>
|
||
|
|
<p>If
|
||
|
|
you send an inquiry message, you can specify that the reply be sent to a message
|
||
|
|
queue other than that of your display station.</p>
|
||
|
|
<p>The following <span class="cmdname">Send
|
||
|
|
Break Message (SNDBRKMSG)</span> command is sent by the system operator
|
||
|
|
to all the display station message queues: </p>
|
||
|
|
<pre>SNDBRKMSG MSG('System going down in 15 minutes')
|
||
|
|
TOMSGQ(*ALLWS)</pre>
|
||
|
|
<p>The disadvantage of sending this message is that it is sent
|
||
|
|
to <em>all</em> users, not just those users who are active at the time the message
|
||
|
|
is sent.</p>
