When Do IBM i PTFs Get Applied Anyway? (IT Jungle)

IT Jungle just published my new tip where I answer this question on when IBM i PTFs get applied:

Our management has our operators apply cumulative PTFs (CUME) with no regard to when the system will be IPLed. They load the CUME, and the system may not be IPLed until a few weeks later. The managers believe that no PTFs are applied until after the IPL. I think that some PTFs are applied immediately, while others wait for the IPL. What’s the real story on how PTFs are applied?

Strangely enough, the answer is and isn’t as straightforward as you might think, depending on how you configure your service attributes.
