Sure, let SQL bomb because you run out of disk space. You can remedy the problem until you find the culprit. Yup, some sp was running out of schedule that was hogging the tempdb during daytime.
Thanks to everyone. Tempdb is used for workfiles like sort workfiles plus working space when doing large queries or index rebuilds.
I find it usually grows because of large operations like index rebuilds. I usually just leave it at whatever size it grows to. However, you can use permanent work tables instead of temporary tables if appropriate, requires design change. Or you can add more files to tempdb no design change Best: track down what is causing the growth.
It may be a bad runaway unoptimized query. You can use a combination of perfmon and SQL Server Profiler tracing to find the culprit by combining the two traces supported feature!

For better answers on performance questions, click on the following I don't know why it grown so much, so for I think that the first step is to try to shrink it and see what happened.
You can shrink the database by using dbcc shrinkfile command. By the way what is the size of the data file? Lynn Pettis. You may want to look into moving tempdb to its own disk drive or set of disk drives. You can find instructions on moving tempdb in BOL. Shrinking tempdb may give you back some space, but if SQL Server needs more space again it will have to grow tempdb again and that will also impact your systems performance as mentioned earlier in this thread. There is no need to do a backup because this is the TempDB.
Tempdb on c. Only 2GB free on c. Server guys wont give me any more space until the next scheduled outage weeks. I like the approach Marcy posted. However, I have seen some procs kill tempdb quickly like this one… just to return analysis info…. TEXT, qs. This worked the way it is supposed to. Thank you for your tip. I have this issue for last 3 days and finally i could get this solution. Thank you again. Sometimes you have to restart it in single-user method.
And, in my case, also undo-the max connections of 1. Do you have any links for when single-user mode is necessary? Until today, when I found this article, and it worked. Useful bit of info. But like others have mentioned, after you run this, you will have to look for a root cause, as it may just go right back to growing the database again.
It was really clear once I filtered down to the timeframe in question and sorted by the tempdb allocation column. I then sent an email to the business user who wrote and was running the query. The files were set to initialize at 20GB each, and as soon as the user tried running their job, it was maxing out TempDB. When a temp db file will not shrink, check its initial allocation. Yea, Temp DB file 1, 3, and 4 where configured at 20 gig. TempDB 2 was configured at 56 Gb as initial extent or file size.
This might make a great test question. There are no good test questions. No good test questions? Are there any good answers? If so, how do we find them answers? I agree about Temp DB files. Ran into this one today on a DB I did not build but was asked to fix. It will take three weeks to fix the file size: — sigh life by multiple committee. One other repair — Temp DB uses a different collation than the database. Anyone else notice that the size reported by master. Any ideas why that is?
This is across versions R2, , , and only appears to be tempdb — none of the other databases show this discrepancy. It worked before and that is what led me to wrong direction. Now evrything is good.
I had two tempdb data files that had blown out to GB. After trying your steps I managed to shrink to 10GB, hurray… outage averted but still had the other pesky file not playing nice. Tried it multiple times definition of lunacy and then found that increasing the file by a few megabytes and then running the dbcc shrinkfile allowed me to shrink both files to manageable numbers.
What I am wondering, though, is why tempdb is tied to the procedure cache? Your email address will not be published.
