Hi!
I'm studying to have my MCSE 70-228 certification and I'm trying some
things with backing up transaction logs and shrinking it.
Here's what I do:
There is no activity in the database by the way.
I have a transaction log of 1792 kb...
I do the following command:
BACKUP LOG TestDB TO TestDBBackup
DBCC SHRINKFILE ('TestDB_Log',0 )
The transaction log is now 1280 kb
I do the same command and finally my transaction log is now 1024kb...
Any idea why it didn't shrink it at 1024 kb the first time?
Thanks!

Dunno really. Books Online says that if you don't specify a
target size, the file shrinks to its default size. But I seem to
recall that this is not the true story.
In any case, I think it is a good idea to always specify a target size,
particularly with a transaction log. The log file may have swollen to,
say 1GB, because of some unusual operation. Shrinking it all the way
down to 1024 kB would be a bad idea, because the file grow again, and
the autogrows costs in performance. So shrinking to a reasonable target
size is a better idea.

Hello All,
I have been encountering trouble with a SQL Server 2000 Transaction
log file, mainly with the constant growth and lack of the autoshrink
option. Here are the details:
1.) OS is Windows 2000 server sp3
2.) SQL Server 2000 (Build 2195) sp3
3.) Database Recovery Mode is set to Full
4.) Maintenance Plan for "Transaction Log Backup" is set to remove
files older then 1hr.

I have set the initial size of the log file for a database to 1M, the
maximum size is unrestricted, and the increase rate is 10%.
However, when I attempt to delete thousands of rows, the error is still
reported that the transaction log file is full. Why can't the log file
increase automatically?

Hi Friends,
I have tried almost everything but I cant seem to shrink the
transaction log.
Executing DBCC SQLPERF(LOGSPACE)
gives me this info:
Database Log Size (MB) Log Space Used (%) Status
MY_eems 368.49219 16.034182 0
I made a complete backup of the database and transaction log and then
executed this statement:
DBCC SHRINKFILE (MYeems_log, 1)

Hi,
We have created a SQL server 2000 database. We observe that the
transaction log keeps growing over time. We are now about to run out of
space. We have been periodically shrinking the database. Nevertheless
the size has increased. I would imagine that a transaction log can be
eliminated if we stop the database. Can that be done? Is there a way to
completely wipe off the transaction log?
Thanks,

Hi All,
My SQL server transaction log is getting bigger every day and my HDD if
running out of space.
So i follow the MS KB about how to Shrinking the Transaction Log.
After doing so the log is much much smaller as i can see the size of it
under enterprise manager.
The problem is that the HDD still shows the same size.
If i shrink the DB why the and reduce its size why the HDD does not

Good day,
I have some problems regarding my Hard disk space for my logs in SQL Server 2005. When I try shrinking the database it returns an error not letting me to do anything about the size of the file.
Is there any way that I can delete the used transaction logs in my LOG File to free some disk space that I need. I cannot delete or add any new files on my database, because the transaction log file is full.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
