Re: IPL with future date
Just speaking form my Y2K testing experience You are inviting problems with future dates on current systems. We had to do a complete reinstall of SAS because we did what you describe on a real system (not an emulator).

Re: IPL with future date
What kind of testing are you trying to do? There are date simulator products like HOURGLASS or I think Compuware has one. With these products your applications can pick a date and time to run in and not affect the rest of the environment.

Jim Don't do it - a recipe for disaster and you will get lots of You did WHAT? from vendors if anything breaks. Dump/Copy the stuff you want from the live system and then isolate your timewarp system from everything else.

Re: IPL with future date
We did an extensive date progression test for Y2K. We went to the DR site, rented extra time, and played with it for a week. I'm fairly certain we got extended keys from our vendors to avoid that problem. Once we started moving forward, though, we never fell back. Beware the SIBW!!!

Re: IPL with future date
Shane Just some bad experiences from Y2K. You're looking for trouble with any backup/restore mechanism that is date sensitive . You're also looking at software licensing that may selectively go crazy (if it's using an anti-tampering algorithm). The only way to do this is to completely isolate the system or use software designed for time warping (and there should some around left from the last millennium ...)

Don't forget that if your date is far enough into the future, and you're using RACF, you'll end up getting users revoked for inactivity. That will not affect PROTECTED users, nor SPECIAL users, nor (to some effect) STC user IDs, but it will affect everyone else.
