<h1 class="topictitle1">Compare and update fixes</h1>
|
|
<div><p>Use <span class="keyword">iSeries™ Navigator</span> to
|
|
compare fixes across your systems or networks of systems. You then have the
|
|
choice to update your systems with the missing fixes. Find out how the Compare
|
|
and Update wizard works.</p>
|
|
<div class="section"><p>iSeries provides
|
|
tools and wizards to help you effectively manage your fixes. You will find
|
|
the Compare and Update wizard to be very helpful. The wizard compares the
|
|
fix levels of a single system or multiple systems to a model system. You can
|
|
send the save files of the missing fixes from a source system and then install
|
|
the fixes to ensure the systems have the same level of fixes. You can also
|
|
choose which missing fixes you want to send. You can launch the Compare and
|
|
Update wizard from an endpoint system, a system group, or from a system in
|
|
your list of connections.</p>
|
|
<div class="note"><span class="notetitle">Note:</span> Even though the Compare and Update wizard
|
|
does not prevent you from comparing and updating fixes on systems at different
|
|
cumulative levels, it is recommended that your systems be at the same cumulative
|
|
level. Use the GO PTF menu to ensure that your systems are at the same level,
|
|
and then use the Compare and Update wizard to work with a smaller number of
|
|
differences. By following this recommendation, you ensure that the special
|
|
instructions that accompany the cumulative PTF packages are followed.</div>
|
|
<p>To
|
|
compare and update the levels of your fixes inventory, you need to define
|
|
a model system and a source system. Your source system will have the fix save
|
|
files on it. You will use your model system to compare against other systems
|
|
in your network to ensure that your other systems have the same level of fixes
|
|
like the model system. The Compare and Update wizard finds missing fixes and
|
|
extra fixes on the target systems. The following figure shows you a sample
|
|
network.</p>
|
|
<p>Also, you can perform only a compare of fixes with the Compare
|
|
and Update wizard. You can choose to review your list of missing and extra
|
|
fixes without requesting to perform an update for the missing fixes.</p>

|
|
<ol><li class="stepexpand"><span><strong>Set up your model system</strong></span> <p>Set up a model system
|
|
that has the appropriate fixes installed for the particular products, all
|
|
fixes for all products, or fixes for particular releases. In some instances,
|
|
your model system might be your central system. You should define a model
|
|
system that works best in your environment. To set up your model system, follow
|
|
these steps:</p>
|
|
<ol type="a"><li><span>Determine which fixes you want installed on the model system.</span></li>
|
|
<li><span>Install those fixes.</span></li>
|
|
</ol>
|
|
</li>
|
|
<li class="stepexpand"><span><strong>Set up your source system</strong></span> <p>Verify that the
|
|
save files for the fixes exist on the source system for the fixes that are
|
|
installed on the model system. In some instances, your source system might
|
|
be your model system. Get the save files to the source system by using the
|
|
copy from media function.</p>
|
|
</li>
|
|
<li class="stepexpand"><span><strong>Refresh your inventory</strong></span> <p>The comparison is done
|
|
based on the information in the inventory, and now that you set up your model
|
|
system and your source system, you may want to refresh the inventory at this
|
|
time. If you do not refresh your inventory now, the Compare and Update wizard
|
|
gives you the opportunity to refresh the inventory.</p>
|
|
</li>
|
|
</ol>
|
|
<div class="section"><p>You can have the wizard perform a comparison, and optionally, send
|
|
missing fixes, or send and install missing fixes after the compare has completed.
|
|
As a general reminder, because a collected inventory is used to perform this
|
|
task, it is important that you have an inventory that is current. You should
|
|
collect your fixes inventory on all systems before you perform the compare
|
|
and update task.</p>
|
|
<p>To <strong>compare and update fixes on your target systems</strong>,
|
|
follow these steps:</p>
|
|
<ol><li>In <span class="keyword">iSeries Navigator</span>, expand <span class="uicontrol">Management
|
|
Central</span>.</li>
|
|
<li>Expand <span class="uicontrol">Endpoint Systems</span> or <span class="uicontrol">System Groups</span>.</li>
|
|
<li>Right-click a system or a group and select <span class="uicontrol">Fixes</span>,
|
|
and then <span class="uicontrol">Compare and Update</span>.</li>
|
|
<li>Use the Compare and Update wizard to determine what fixes are missing
|
|
from the target system when compared to your model system. When you have finished,
|
|
Management Central can send or send and install any missing fixes on the target
|
|
system. When the missing fixes are installed, the target systems then have
|
|
the same level of installed fixes as the model system.</li>

<div><div class="section">Scenarios can exist where a fix on the model system is listed as

|
superseded on the target system. In this case, the compare and update function
|

tells you that the fix is missing on the target system because the superseded

fix is not installed or the superseding fix is not installed. The fix continues
|
|
to show as missing until the superseding fix is installed. A fix with a <em>Superseded</em> status

does not mean that the later fix was installed. You can still load and apply

the fix. A status of <dfn class="term">Superseded</dfn> means that a later fix exists
