<div><p>Record and print system values. Check the QSYSLIBL, QUSRLIBL, QALWOBJRST,
|
|
and QVFYOBJRST system values.</p>
|
|
<p>System values are IBM-supplied objects that can be modified from their shipped
|
|
value to tailor certain aspects of the operating system to your environment.
|
|
The software installation program will overlay these objects on your system
|
|
with values that are supplied on the installation media.</p>
|
|
<p>IBM also recommends that you first <a href="settingtimezone.htm#settingtimezone">create
|
|
a data area to specify your system time zone</a> before you upgrade to <span>V5R4</span>. This data area is used when you upgrade to set the time
|
|
zone system value. By doing this, the time zone used on the system is set
|
|
immediately. </p>

To ensure that your installation runs smoothly, check the system library list (QSYSLIBL), user library list (QUSRLIBL), allow restore of security sensitive objects (QALWOBJRST), and verify object signatures during restore (QVFYOBJRST) system values.</li>
