<div><p>Use this information to learn about system commands and system
values that you can use to work with signed objects and how signed objects
affect backup and recovery processes.</p>
<p>Beginning in V5R1, IBM<sup>®</sup> started signing i5/OS™. licensed programs, and PTFs as a
way of officially marking the operating system as originating from IBM and as a means
of detecting when unauthorized changes occur to system objects. Also, business
partners and other vendors may be signing the applications that you purchase.
Consequently, even if you do not sign objects yourself, you need to understand
how to work with signed objects and how these signed objects affect routine
system administrative tasks.</p>
<p>Signed objects primarily affect backup and recovery tasks, specifically
how you save objects and restore objects onto your system. </p>
