<h1 class="topictitle1">Scenario: Workstation allocation</h1>
<div><p>The following is an example of how two workstations are allocated
to two different subsystems.</p>
<p>In this scenario, subsystem A and subsystem B have workstations DSP01 and
DSP02 in their subsystem descriptions (the workstation entries specify <span class="parmname">AT</span>(*SIGNON)).</p>
<div class="tablenoborder"><table cellpadding="4" cellspacing="0" summary="" frame="void" border="1" rules="all"><thead align="left"><tr><th valign="top" id="d0e23">Device Name</th>
<th valign="top" id="d0e25">Allocated to</th>
</tr>
</thead>
<tbody><tr><td valign="top" headers="d0e23 ">DSP01</td>
<td valign="top" headers="d0e25 ">Subsystem A</td>
</tr>
<tr><td valign="top" headers="d0e23 ">DSP02</td>
<td valign="top" headers="d0e25 ">Subsystem A</td>
</tr>
</tbody>
</table>
</div>
<p>Assume that both workstations are varied on when subsystem A is started.</p>
<p> Subsystem A allocates both workstations and shows the signon display
on both. Even though subsystem A has the signon display shown on the workstations,
they can be allocated by another subsystem or job; the workstation will then
no longer be available to subsystem A.</p>
<div class="tablenoborder"><table cellpadding="4" cellspacing="0" summary="" frame="void" border="1" rules="all"><thead align="left"><tr><th valign="top" id="d0e48">Device Name</th>
<th valign="top" id="d0e50">Allocated to</th>
</tr>
</thead>
<tbody><tr><td valign="top" headers="d0e48 ">DSP01</td>
<td valign="top" headers="d0e50 ">USER1</td>
</tr>
<tr><td valign="top" headers="d0e48 ">DSP02</td>
<td valign="top" headers="d0e50 ">Subsystem A</td>
</tr>
</tbody>
</table>
</div>
<p>When a user (USER1) signs on to workstation DSP01, the device is allocated
to USER1's job, which is running in subsystem A. Workstation DSP02 is still
at the signon display. Thus it can be allocated by another subsystem or job.
It is then no longer available to subsystem A.</p>
<div class="tablenoborder"><table cellpadding="4" cellspacing="0" summary="" frame="void" border="1" rules="all"><thead align="left"><tr><th valign="top" id="d0e71">Device Name</th>
<th valign="top" id="d0e73">Allocated to</th>
</tr>
</thead>
<tbody><tr><td valign="top" headers="d0e71 ">DSP01</td>
<td valign="top" headers="d0e73 ">USER1</td>
</tr>
<tr><td valign="top" headers="d0e71 ">DSP02</td>
<td valign="top" headers="d0e73 ">Subsystem B</td>
</tr>
</tbody>
</table>
</div>
<p>Subsystem B is started. Because USER1 has signed on to workstation DSP01,
subsystem B cannot allocate the device. Subsystem B requests allocation of
the device when it becomes available. DSP02 is allocated to subsystem B because
no one has signed on to it in subsystem A. Any jobs started on DSP02 will
run in subsystem B.</p>
<div class="tablenoborder"><table cellpadding="4" cellspacing="0" summary="" frame="void" border="1" rules="all"><thead align="left"><tr><th valign="top" id="d0e94">Device Name</th>
<th valign="top" id="d0e96">Allocated to</th>
</tr>
</thead>
<tbody><tr><td valign="top" headers="d0e94 ">DSP01</td>
<td valign="top" headers="d0e96 ">Subsystem A</td>
</tr>
<tr><td valign="top" headers="d0e94 ">DSP02</td>
<td valign="top" headers="d0e96 ">Subsystem B</td>
</tr>
</tbody>
</table>
</div>
<p>USER1 signs off. Because the user job was running in subsystem A, that
subsystem displays the signon display so that another user can sign on the
workstation and run in subsystem A. If subsystem A is ended, workstation DSP01
is allocated by subsystem B (because it has an outstanding request to allocate
the device.)</p>
<p>The name of the subsystem that currently has a workstation allocated appears
in the upper right corner of the IBM-supplied signon display.</p>
