A new Redbook TechNote from Don Zimmerman of IBM Rochester addresses a surprising change in i/OS 6.1: journaling of logical files, SQL views, and indexes. This change will affect you whether you are using the Start Journal Physical File(STRJRNPF) and Start Journal Access Path(STRJRNAP) commands or if you are employing System-Managed Access Path Protection (SMAPP). The new Logical file journaling in 6.1 is referred to in the Technote as "covert" journaling. Here's a quote from the IBM TechNote:

"Starting in IBM i 6.1, logical files, SQL views, and SQL indexes will be journaled, even if you do not change your environment. Why did the operating system starting journaling your logical files? Why are some journaled and some not journaled? How can you end journaling for some of them or start journaling for others? This technote addresses these questions and more."

As you move to i/OS 6.1, you will need to be aware of this new journaling change to properly manage your system.
