I was trying to backup db and truncate the log, here's what I did..
1) Used sp_addumpdevice danV2_db
2) Backup danV2 to danV2_db
3) Used sp_addumpdevice danV2_log
4) Backup danV2_log to danV2_log
Then I tried..
DBCC SHRINKFILE(danV2_log, 5)
...but I got the following error...
"Could not shrink danV2_log. All logical drives are in use" or something.
What does this mean, why can't I shrink the log? Or what did I miss?
Thanks,
Dan
Easy way...
Right click on database in Enterprise Manager.
Select shrink database , select the logfile you wan't to shrink.
I drank alot of beer and ended up in the police department database.
Drank more beer and learned SQL in the dark hours.
DELETE FROM offenders WHERE Title=''MrAA'' AND Year=2006;
I love SQL

enough that I can't actually see the header info in my cmd info once it's run.
Is there a way to "page" the dbcc loginfo command (like more in msdos) ?
Once I do find the last vlf - how do I then start to shrink the database?!

|||Hi, Dan,
First, I notice that you said:
"
4) Backup danV2_log to danV2_log
Then I tried..
DBCC SHRINKFILE(danV2_log, 5)
"
This seems not right. danv2_log should be a logical device name for storing
your database transaction log backup file; however it (logical device name)
was used as a parameter (logical file name) in DBCC SHRINKFILE. Is it a
writing mistake?
From the error message, I think that the cause is most likely that the
database was being used by other people when you perform BACKUP LOG and
DBCC SHRINKFILE operations.
Please run sp_who2 to check if some other users are using your database. If
so, please ask them to log off. Make sure that only you use the database.
After that, please run BACKUP LOG ... WITH TRUNCATE_ONLY again and then
run DBCC SHRINKFILE(file_name, target_size).
If this issue persists, could you please post the full error message here
for further research?
Please feel free to let us know if you have any other questions or concerns.
Have a good day!

Charles Wang

|||Hi Charles,
Thanks for the information. Can I get some clarification on using DBCC
shrinkfile? I thought you gave it the name of the log as referenced in osql?
Are you saying I need to give it the actual log file location, ie..
DBCC SHRINKFILE('c:\danSQL\dabV2_log.bak', 5)
If not, where do I find out what the "logical device name" for the log file
is, so I can shrink it?!
Thanks,
Dan

|||Hi again Charles,
Just a bit more info on my database log file. I just ran a sp_helpfile to
determine the names of the log files..
danV2_log
c:\dansql\data\danV2_log.ldf
NULL
2653056kb
Umlimited
10%
log only
So, should I use the name danV2_log in my shrinkfile command, or the full
file path? Or am I missing a step?
Thanks,
Dan

DBCC SHRINKFILE is used for shrinking the transaction file (.ldf) not the
backup file (.bak or .trn). Logical file name should be used in DBCC
SHRINKFILE.
Your saying "Backup danv2_log to danV2_log" make me think that danV2_log is
a backup device name which cannot be used in DBCC SHRINKFILE. Since you
have pointed that dan2_log is the logical file name, you can use it in DBCC
SHRINKFILE.
Tibor's suggestion is helpful. Please first ensure that only you log on
your SQL Server and then try backing up your transaction log with truncate
only and shrink the file several times.
If this issue persists, please feel free to post back. We would like to
work with you for further research.

|||Hi Charles and Tibor,
You'll both be glad to know... I've sussed it. Although to be fair, I'm not
entirely sure what I was doing wrong.
danV2_log is the name of the log as provided by sp_helpfile, and I'd also
named my dump device as that too, so that probably confused matters.
To clarify for future, here's what I did..
USE master
EXEC sp_addumpdevice 'disk', 'danV2_db', '<filepath>'
EXEC sp_addumpdevice 'disk', 'danV2_log', '<filepath>'
BACKUP DATABASE danV2 TO danV2_db
BACKUP LOG danV2 WITH TRUNCATE_ONLY
USE danV2
DBCC SHRINKFILE(danV2_log, 20)
go
I'd like to thank you both for your conitued help with this one. Hopefully
it won't be so painful next time!
And I have just one final question for you... if I keep doing a full backup
everyday, can I use the full backup to do a restore if anything goes wrong?
(I know it's not the best solution but it'll do until we our new SQL Server
2005 system setup).
Thanks again,
Dan

If all you are going to do with the log is back it up with truncate only,
then you might as well put the DB into Simple Recovery Model and just do
full backups only.
