Rosanne: Hi, Tom. I'm proctoring a DiRT exercise. You are on call for [name of ser-
vice], right?
Tom: I am.
Rosanne:Inthisexercisewepretendthe[nameofservice]databaseneedstoberestored
from backups.
Tom: OK. Is this a live exercise?
Rosanne: No, just talk me through it.
Tom: Well, I'd follow the directions in our operational docs.
Rosanne: Can you find the doc?
[A couple of key clicks later]
Tom: Yes, I have it here.
Rosanne: OK, bring up a clone of the service and restore the database to it.
Over the next few minutes, I make two discoveries. First, one of the commands in the
document now requires additional parameters. Second, the temporary area used to do the
restore does not have enough space. It had enough space when the procedure was written,
but the database has grown since then.
Rosanne files a bug report to request that the document be updated. She also files a bug
report to set up a process to prevent the disk-space situation from happening.
I check my email and see the notifications from our bug database. The notifications are
copied to me and the bugs are tagged as being part of DiRT2011. Everything with that tag
willbewatchedbyvariouspartiestomakesuretheygetattentionoverthenextfewmonths.
I fix the first bug while waiting for the restore to complete.
The second bug will take more time. We'll need to add the restore area to our quarterly
resource estimation and allocation process. Plus, we'll add some rules to our monitoring
system to detect whether the database size is nearing the size of the restore area.
Tom: OK, the service's backup has been read. I'm running a clone of the service on it,
and I'm sending you an instant message with a URL you can use to access it.

Rosanne: OK, I can access the data. It looks good. Congrats!
Tom: Thanks!
Rosanne: Well, I'll leave you to your work. Oh, and maybe I shouldn't tell you this, but
the test controllers say at 2 PM there will be some fun.
