rename logical file

Hi,
I have 3 databases running on Production server. All the databases have
names like AA, BB and CC with their Logical Data Files and Log files named a
s
AA_Data and AA_Log, BB_Data and BB_Log except for the third one. I want to
rename it as CC_Data and CC_Log to make it consistent. Would this renaming
affect anything on the server?You can change the logical file names, using ALTER DATABASE, without taking
the DB's offline.

Would it affect anything / any process on the production server?

Can you please explain to me what exactly is the purpose of a logical
Filename? When we have more than one databases on one SQL Server, can we hav
e
the same logical name for all the databases? Thanks in advance.

client and what all of your DB maintenance scripts to do the same thing to
each customer DB.

Yes. Easiest, IMO, is detach and attach the database. In 2005, you can use A
LTER DATABASE to change
the physical name, stop SQL Server, copy the file, and then start SQL Server
. I don't find this very
useful, so I prefer detach and attach better in 2005 as well.

Hi Tibor,
I've been experimenting with detach/attach and I can't (for the life of me)
figure out how to change the name on the fly -- in MSS 2005 (or earlier
release for that matter). Maybe I'm going about this all wrong ... all on
the same server ... Here's my situation ... I have a database that I want to
clone and rename on the same server.
I have one database named "Database1" (c:\data1\d1.mdf, c:\data1\d1.ldf).
I detach the original database and copy both files to a new directory
x:\data2\d1.mdf, x:\data2\d1.ldf).
I re-attach the original database Database1 using MSS Management Studio.
Then I attempt to attach the 2nd database, I'll browse to the new directory
and select the duplicate d1.mdf, but it won't let me change the database
name, so I abort.
Then I manually rename both the (copied) database and the log files from d1
to d2 (x:\data2\d2.mdf and x:\data2\d2.ldf) and try to attach again.
When I attach the newly renamed files, MSS remembers both the original file
names and the original database name "Database1" and will complain if I clic
k
OK to try and save the 2nd database to the host/instance. I don't see how t
o
1) change the original database name when attaching or 2) force the MSS
system to let me change the new database name on the fly as I attach it.
Sorry if the answer is looking me in the face
