I'm not going to argue with you; you like journals and I think they're often overkill. But I will say this: journals do NOT protect you from application failures. If you write bad code, it will write bad transactions, and the journal will happily record them. The only time a journal saves you is if a production program hard halts, and if you have a lot of that, you have much larger problems than a journal can save you from.

Rule of thumb: if it's a hardware or system software problem, journaling can help. If it's an application programming problem, they cannot.

That being said, journals on critical transaction files are often a good thing. Journals on master files not so much. Journals on temporary files are a bad thing.

Again, just my opinion. I just get a little spooked when people start saying "you must always do xxxxx" because in reality it's almost always a case-by-case business decision.
