<h1 class="topictitle1">Take over or recover an Operations Console connection</h1>
|

|
|
<div><p>Use these functions to take control of another console device. </p>
|
||
|
|
<div class="section"><p>A special set of functions included in i5/OS allow an Operations
|
||
|
|
Console to take control from another console device. The two main actions
|
||
|
|
that you can do are:</p>
|
||
|
|
<ul><li><span class="uicontrol">Take over</span> is the process used for a LAN-connected
|
||
|
|
console-capable device to take control from the current LAN-connected console
|
||
|
|
device. This take over action can not be used with directly attached consoles.</li>
|
||
|
|
<li><span class="uicontrol">Recovery</span> is the process of regaining control of
|
||
|
|
the job running on the console after a problem with the console was encountered.
|
||
|
|
The recovery process may be to the same console device or a different console
|
||
|
|
device and may be facilitated by additional work to enable a device using
|
||
|
|
a different connectivity. The exception is twinaxial console which does not
|
||
|
|
use the same type of 5250 emulation and thus cannot recover the console.</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<div class="section"><img src="./delta.gif" alt="Start of change" /><p>Every console-capable device running 5250
|
||
|
|
emulation, regardless of connectivity, will be presented a screen of data
|
||
|
|
regardless of whether or not it is the console when it successfully connects.
|
||
|
|
This means that now, more than one device will have data on the screen after
|
||
|
|
the console has been established. A console device will not have a blank screen
|
||
|
|
showing <tt class="sysout">Disconnected</tt>. This action allows the
|
||
|
|
job at the console to be "transferred" to another device without causing loss
|
||
|
|
of data. When the console option for take over is enabled, the server also
|
||
|
|
has enhanced recoverability from loss of the console.</p>
|
||
|
|
<img src="./deltaend.gif" alt="End of change" /></div>
|
||
|
|
<div class="section"><p>The recovery action is accomplished by suspending the data stream
|
||
|
|
to a console that loses a connection, or is being taken over, saving further
|
||
|
|
data and then sending that data to the next device to become the console,
|
||
|
|
even if the device is the same former console. Recoverability is essentially
|
||
|
|
just taking over the console from the same or different qualified device regardless
|
||
|
|
of what the former console was doing.</p>
|
||
|
|
</div>
|
||
|
|
<div class="section">The default setting for the console take over and recovery function
|
||
|
|
is <span class="uicontrol">disabled</span>. If this function is disabled, all console-capable
|
||
|
|
devices will display the <tt class="sysout">Console Information Status</tt> screen
|
||
|
|
whenever they are not the active console.</div>
|
||
|
|
<div class="section"><p>Benefits of these functions include convenience and redundancy.
|
||
|
|
Console capable devices can be placed around a site, or multiple sites, allowing
|
||
|
|
users to move around and gain control of the system from any of these devices.
|
||
|
|
Whatever the previous console's activity was, the new console will be at
|
||
|
|
the exact same place, even during the process of restarting the server or
|
||
|
|
installing <span class="keyword">i5/OS™</span>. When
|
||
|
|
the console option for takeover is enabled, the server also has enhanced recoverability
|
||
|
|
from a loss of the console.</p>
