<div class="section"><p>This information
|
||
|
|
is provided to assist you in estimating the approximate installation time
|
||
|
|
of this release on your system. Use the following checklist as a guide. The
|
||
|
|
checklist refers you to other information or work sheets to obtain values. </p>
|
||
|
|
<p>The
|
||
|
|
checklist assumes that you are not changing the primary language of your system.
|
||
|
|
The estimate you arrive at by using this checklist is based on the assumption
|
||
|
|
that your system must perform a single-process installation. If your system
|
||
|
|
is able to use multiprocess installation, your time will be less.</p>
|
||
|
|
<p>The
|
||
|
|
checklist and supporting work sheets do not include the amount of time that
|
||
|
|
is spent on loading <span>the</span> next volumes, media errors, or recovery
|
||
|
|
procedures. User data is not included. The time needed for INZSYS to complete
|
||
|
|
is also not included.</p>

time from the last backup of your system. <p>Time: _____________</p>
