Re: Modernizing applications

If you journal *BEFORE and *AFTER images, then yes, you could in
theory roll back the delete using RMVJRNCHG.

However, it's not a command to take lightly. In addition, off the top
of my head, I'm not sure if it would work if you used CLRPFM instead
of for instance running an RPG program that deleted all the records
using RLA.

The second option, would be to restore the file, then APYJRNCHG to the
object up to the point at which the delete was issued. That's
probably a better way to recover.

My boss told me that, before I came to work here, he accidentally cleared our order details file.  (How one can do that accidentally is a mystery to me, but I digress.)

Everyone in the office spent the rest of the day re-entering the orders from printed picking tickets.

As I said before, I am not a journaling expert (or even novice), but wouldn't journaling be of no benefit in such situations?  I.e., it seems to me that the journal would simply said something along the lines of "Order 123 deleted" ad nauseum.  Applying the journals would result in nothing being recovered.  Or is there a rollback option, such as "Roll the Order Details back to its state at Noon."?
