<h1 class="topictitle1">Allow restore for security-sensitive objects</h1>
|
||
|
|
<div><p>Three system values, Verify Object on Restore (QVFYOBJRST), Force
|
||
|
|
Conversion on Restore (QFRCCVNRST), and Allow Object Restore (QALWOBJRST),
|
||
|
|
act as a series of filters to determine whether a program is restored without
|
||
|
|
change, whether it is re-created as it is restored, or whether it is not restored
|
||
|
|
to the system.</p>
|
||
|
|
<p>The QVFYOBJRST system value determines whether objects are required to
|
||
|
|
have digital signatures to be restored to your system. You can prevent anyone
|
||
|
|
from restoring an object, unless that object has a correct digital signature
|
||
|
|
from a trusted software provider.</p>
|
||
|
|
<div class="p">The QFRCCVNRST system value allows you to specify whether to convert the
|
||
|
|
following object types during a restore: <ul><li>Program (*PGM)</li>
|
||
|
|
<li>Service program (*SRVPGM)</li>
|
||
|
|
<li>Module (*MODULE)</li>
|
||
|
|
<li>SQL Package (*SQLPKG)</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<p>The QALWOBJRST system value determines whether objects that are security-sensitive
|
||
|
|
may be restored to your system. You can use it to prevent anyone from restoring
|
||
|
|
a system state object or an object that adopts authority.</p>
|
||
|
|
<div class="p">Before running a restore operation, you must plan what type of restore
|
||
|
|
you want to perform. Then, configure your system values to the proper settings
|
||
|
|
to meet your needs. Then, when a restore operation is performed, you will
|
||
|
|
have the correct settings specified on your system. To plan how you want
|
||
|
|
objects restored on the system, answer the following questions based on your
|
||
|
|
company's needs: <ul><li>How cautious do you want to be about what is restored?</li>
|
||
|
|
<li>What objects do you want to allow to be restored?</li>
|
||
|
|
</ul>
|
||
|
|
</div>
|
||
|
|
<div class="p">For more information on using these restore system values, see the following
|
||
|
|
sections in Chapter 3 of the <a href="../books/sc415302.pdf" target="_blank">iSeries Security Reference</a>:<ul><li><span class="q">"Verify Object on Restore (WVFYOBJRST)"</span></li>

|
<p><strong>Scan objects that are accessed after a restore operation:</strong></p>
|
||
|
|
<p>The *NOPOSTRST value of the system value, QSCANFSCTL, impacts
|
||
|
|
whether or not objects are scanned after a restore operation. Do you want
|
||
|
|
to scan objects on the next access after the restore is complete? You need
|
||
|
|
to consider what objects you are restoring and what kind of performance impact
|
||
|
|
the scan will cause. Before determining whether or not to scan objects consider
|
||
|
|
the following: Scanning may not be necessary if you are restoring your own
|
||
|
|
objects which were saved with the option to scan objects and not save objects
|
||
|
|
that failed the scan. Scanning may not be necessary if you are restoring objects
|
||
|
|
that are coming from a trusted source. </p>
