I am not sure what you are asking but sp_helpfile will give the names and
locations of the files associated with a current database. 2) Is it safe to delete it, as SQL will create a new Transaction Log when

I would not recommend deleting any logfile. If SQLServer is running then you
won't be able to as the file is locked. If you have detatched the database
or SQL Server is not running, you may have problems re-attaching the
database or connecting to it once SQL Server is running. 3) When trying to do 2) I get error message that file is in use, even

I doubt if you have stopped the service, but in any case you should not be
deleting it.

I don't know what this error is, at a guess there is a lack of disk space.
Maybe there is more information in the SQL Server log file or in the Event
log. You will also get errors if you backup to a mapped network drive.

John, thanks for the valuable information.
Where is the 'Transaction Log' located? I can't find the answer sp_helpfile

Does a Transaction Log exist per database in SQL Server? When backup occurs,
does these Transaction Log shrink?

Thanks for any replies to my ignorance.
Your transction logs are held in the ldf file which sp_help would give e.g
for Northwind you would get something like:
Name FileId filename filegroup Size Maxsize Growth Usage
Northwind 1 E:\MSSQL\DATA\northwnd.mdf PRIMARY 3008 KB
Unlimited 10% data only
Northwind_log 2 E:\MSSQL\DATA\northwnd.ldf NULL 1024 KB Unlimited
10% log only
Northwind_log is the internal logical name for the Transaction Log file
located at E:\MSSQL\DATA\northwnd.ldf. The log only usage shows it is a log
file.
The log file will not automatically shrink on backup, see the link I posted
in the last reply regarding how to shrink it.

Thanks for any replies to my ignorance.
John you've nearly solved my dilemma!!
As per your excellent like I was able to work out that running the 2
following lines will reduce the Transaction File back to it's size!!!
Hooray!!
BACKUP LOG MyDb WITH TRUNCATE_ONLY
DBCC SHRINKFILE (MyDb_log)
However, because MyDb has it's Transaction File full, hence I can't execute
the above two lines. How do I run these commands when MyDb won't let me do
anything to it? To test that the two commands worked I created a dummy MyDb,
grew its Transaction File then executed the two lines and it worked 100%.
Thank you so much for your suggestions!

Hi
I am not sure what you mean by the transaction log being full. It would
normally wrap around or expand if you have the disk space.
What does DBCC SQLPERF(LOGSPACE) say?
Have you looked at the output from DBCC OPENTRAN ( 'database_name' )?
You may want to look at: http://www.support.microsoft.com/?id=256650 http://support.microsoft.com/default...b;EN-US;110139 http://support.microsoft.com/default...kb;EN-US;62866

BACKUP LOG MyDb WITH TRUNCATE_ONLY
DBCC SHRINKFILE (MyDb_log)
If a Transaction File has grown from originally 1Mb to 100Mb, executing the
above 2 lines in a stored procedure will shrink that Transaction File to as
close to 1Mb as possible. This is exactly what I urgently need to do.
However, if the Transaction File is full, hence I'm prevented from running
the stored procedure, how do I execute these 2 lines of code against MyDb?
I've tried using the Query Analyser. Line 1 executes correctly. However line
2 causes the error "Server: Msg 8985, Level 16, State 1, Line 1. Could not
locate file 'MyDb_Log' in sysfiles". I've manually verified that MyDb_Log
does indeed exist in the sysfiles table of MyDb.
Any suggestions?

Hi
Try using the file id instead of the logical file name.
sp_helpfile will give your bother the logical name and the file id.

I am not sure what you mean by not work. As in the link previously
posted, if you last virtual log is in use the file will not shrink

As per your excellent like I was able to work out that running the 2 following lines will reduce the Transaction File back to it's size!!! Hooray!!
BACKUP LOG MyDb WITH TRUNCATE_ONLY DBCC SHRINKFILE (MyDb_log)
However, because MyDb has it's Transaction File full, hence I can't execute the above two lines. How do I run these commands when MyDb won't let
me do anything to it? To test that the two commands worked I created a dummy MyDb, grew its Transaction File then executed the two lines and it worked 100%. Thank you so much for your suggestions!

Hi there, I've also got the error "Server: Msg 8985, Level 16, State 1, Line 1. Could not locate file 'MyDb_Log' in sysfiles" when trying to shrink one of my databases's log files. I think I know the cause of the problem. When you de-attach a database, rename the database file and then re-attach the database then this error message will apear. The solution, delete that current database and create a new one but NEVER EVER rename the file name of the database
