Has anyone figured out the parameter sequence to restore a database that doesn’t exist from an alternate timeline where it would have existed if the development project hadn’t failed?

Lowell SSC Guru Points: 323518 More actions · Answer 2

you guys have show some great examples of using a future backup to fix todays data, but I've got a question along a similar vein:

somehow I've forgotten to create any backups on the production database for the last two years. Now the boss wants to archive all the backups off site for disaster recovery.

Based on your wonderful examples, I was able to create a backup today based on a backup i was planning to do in a week or two after I got back from vacation; but now i need to create a history of backups that go BACK two years, so it looks like I was doing my job.

Can anyone help me with the syntax for that?

My hamster just fell through a distortion in the space-time continuum. Is it possible to get him back using DBCC TIMEWARP. Please help, he was my best friend.

Ooops!

Could you please specify your target time?

I guess you messed up one of the addtl. parameter 11 or 13 together with a typo in your space-time value, because all of a sudden something like a hamster materialiezed in my microwafe yesterday. Unfortuntely, I was just cooking some beef stroganoff at the same time. After a rather noisy "PLOPP" (I couldn't find any reason for until I read your post) the beef tasted a little strange and had some fluffy elements I didn't remember to have added... :sick:

Its possible if you have some of its poo.
Oh yeah, plenty of s*** round here :-). Gotta make sure I use the right sample, or could recreate something horrific.
One key ingredient has been left out. Hamster poo is pretty obvious. Swallow poo is critical to the success of your restore. Make sure it is an African Swallow.
Jason, not in this case, this is a hamster we are trying to recover. The hamster could end up corrupted.

Oh yes - good point. In that case, one should take care to maintain a distance of 137 parsecs, avoid any elderberries and keep all swallow guano far from the site. This should help the hamster recover nicely.

Michael, some of the heavyweights may have better answers, but I've tried to do something similar to shortcut the development time cycle on a project. The problem is I don't know the correct parameters for any of the particular alternate timelines where the project has succeeded brilliantly. My first solution was a while loop that tried random parameters, but that proved too slow. Then I reread the Book of Moden and implemented a set-based solution using a tally table with from 1 to infinity rows. It's working much faster and wll probably produce a solution in the next 1100-1200 days, which will still be considerably faster than the development cycle would have been anyway.

In any event, I've now started to leave comments to my alternate selves in my code, just in case.

Lowell: I'm sure a variation of this might work for your purposes.

Merodach: Steve and I did a jump to the left and a step to the right in The Thread, yesterday.

Steve: So happy you approve.

I have to laugh at all you Microsoft acolytes trying to master DBCC Time Warp.

If you'd been working with Oracle instead, you'd know that Ellison's minions realized the fully integrated electro-encephalagraphic interface for SPC (Space Time Continuum) control in January 2023. Parameters? PARAMETERS? I don't got to show you no stinkin' parameters..... Just imagine your solution and when it should have been implemented, and collect your check.

No need to get testy, John. After all, this forum is intended to be a chronosynclastic infundibulum.

John, thats just perapatetic exogmatism.

At least SQL server is fully heterogenous with Oracles electro-encephalagraphic interface for SPC ( a cost extra I might add) simply by using the -T666 flag.

Yes. You remind me that for evaluation purposes one may invoke the Runymede option to open the EEI-for-SPC function set only for dates in 1066, CE. At least by using switch -T1066, MS made it easy to premember.

Also, in full production mode EEI-for-SPC produces so many dmp files in so many different space-time continuums that it requires 3 Oracle DBAs concentrating on it full time.

DBCC Timewarp can be run by a single DBA.

Just starting to investigate this command. Does the setting of "cosmic string count" on the server have any effect?

Just starting to investigate this command. Does the setting of "cosmic string count" on the server have any effect?

Yes. It essentially determines the domain in the SPC where the server can participate. And that's the dirty little secret about the command. Although the string count itself is a simple part of your server settings, the actual reference data is stored in the binary orientation of intergalactic dust particles, the coordinates of which are closely guarded by MS and access rights to which will blow the SW licensing budget of all but the most flush of IT organizations.

Can someone give me a plain English explanation of why parameter 242 is designated as being either "dark matter approximate mass" OR "dimensionality (post M-String)" ??? What controls the context and frame of reference here?

Folks, I need serious help and fast! I have two cores on my system, so tried to use the "[font="Courier New"]-parallel[/font]" option in [font="Courier New"]DBCC Timewarp[/font], but something has gone seriously wrong. I don't think that "parallel" means what I thought it did.
