Re: File Last Changed

Yes. In fact I do a "Save The World" (GO Save 21) both before and after applying PTF's. The time portion indicates that it was close to the latter since I clocked out about 20 minutes later (my boss stayed to pull the tape for off-site storage).

Jerry,
Just a guess, but did you do a backup on 26 May? I see the same type if usage information in one of our dormant libraries. I think we did a data backup on the last changed date, before applying PTFs.

File Last Changed






I have been trying to analyze the *File objects in a library to determine if I really, really need to keep them. One of the tools I'm using on the questionable ones (i.e., no one claims responsibility and I can't find anything that references them) is DSPOBJD.

The weird part (to me) is that a lot of them have a "Last Changed Date" of 26 May 2007 (a Saturday) at about 20:00. I thought that might be because of a PTF (Cume or Group) because I would have done that on a Saturday; in fact, my time log indicates that I did work that day and, other than a natural disaster, applying PTF's is about the only reason that I would have worked on a Saturday. However, I know applied a CUME and Groups to that system on 20 October 2007 (a Saturday, naturally); so that idea doesn't seem to hold water.

And most of those files exhibit a "Last Used Date" earlier (sometimes by a couple of years) than the "Last Changed Date". But, if I (or anyone) actually changed the file in any way, then the "Last Used Date" should get updated, too. Right? Well, that's what my tests (simple DFU on a file) showed, anyway. A simple query against a file affects the "Last Used" but, naturally, not the "Last Changed" date.

I have not been able to find anything in the Info Center (V5R4) or the Archives that would explain why the "Last Changed Date" would be later than the "Last Used Date." Anyone on the List know (or simply want to hazard a SWAG)?
