<div><p>You can keep your system available by effectively planning and
|
|
managing fixes and installing new releases.</p>
|
|
<div class="section"><h4 class="sectiontitle">Manage fixes</h4><p>To reduce the amount
|
|
of time your system is unavailable, you should ensure that you have a fix
|
|
management strategy in place. If you stay current on what fixes are available
|
|
and install them on a routine basis, you will have fewer problems. Be sure
|
|
that you apply fixes as frequently as you have decided is appropriate for
|
|
your business needs. For recommendations on how to create a fix management
|
|
strategy, see <a href="../rzam8/rzam8fixstrategy.htm">Plan
|
|
your fix management strategy</a>.</p>
|
|
<p>Individual fixes can be <span class="uicontrol">delayed</span> or
|
|
<span class="uicontrol">immediate</span>. Delayed fixes can be loaded and applied
|
|
in two separate steps. They can be loaded while your system runs and then
|
|
applied the next time you restart your server. Immediate fixes do not require
|
|
you to restart your system in order for them to take effect, which eliminates
|
|
the need for downtime. Immediate fixes may have additional activation steps
|
|
that are described in full in the cover letter that accompanies the fix. For
|
|
more information on how to apply fixes, see <a href="../rzam8/rzam8fixinstall1.htm">Install
|
|
fixes</a>.</p>

</div>
|
|
<div class="section"><h4 class="sectiontitle">Upgrade to a new release</h4><p>You are required to power
|
|
down your system when you upgrade to a new version of i5/OS™. To minimize the amount of time a
|
|
software upgrade takes, it is important that you plan your installation carefully.
|
|
For information on the planning process, see <a href="../rzahc/rzahcupgradeorreplace.htm">Upgrading
|
|
or replacing i5/OS and related software</a>. </p>
