Managing signed objects
Use this information to learn about IBM i system commands and system values that you can use to work with signed objects and how signed objects affect backup and recovery processes.
Beginning in V5R1, IBM started signing IBM i. 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.
Signed objects primarily affect backup and recovery tasks, specifically how you save objects and restore objects onto your system.
