Down time from shrink?

Hello, everyone:

I have a production database in which data file takes 17GB and used 10GB. I want to shrink it. Once I take about one hour to shrink 1GB. So I am worry long shrinking time. Is there down time during the shrinking that doesn't allow user access?

Thanks

ZYThow big is(are) your log file(s)?

dbcc shrinkdatabase does not require the database to be in single user mode but you may want to schedule some down time as you are likely to see a performance hit on the server and you are going to want reindex after the shrink because of the frgamentation shrinking causes.|||Hi, Sean:

Thanks for the reply. The log file is not big, just be about 100MB. Only data files are too.

If you do: Don't!
If you are running out of disk space: add more disks.|||17GB is tiny for a database. After your shrink, I would review your automatic growth if you are worried about too much free space.
