Transaction Log Files/Virtual Log Files
Oct 1, 2004I am wanting to reduce the amount of Virtual Log Files I have. In reading through the Online Book Documentation, I realize that I have forgotten to move the Transaction Log Files to a different drive. Now that the server is in production, I wanted to get some input about the best way of making this change.
Can I just change the directory the log files are being written to in the DB properties without having any adverse problems occurring?
Transaction Log Files
Dec 5, 2001Hello,
I have a database with two data files as x.mdf, y.ndf and two transaction log files as l1.ldf, l2.ldf. I wanted to have only one log file for this database. What are possible options for me to make these two transaction log files into one transaction log file leaving data files as it is?
Thanks in Advance!

Transaction Log Files
Oct 24, 2006Hi All,
I am trying to understand the difference between the physical, logical and virtual logs. I found some info in BOL, but I am still a little bit confused.
What is the physical file? Is each transaction considered a physical file?
Each physical log file consists of a number of virtual log files.
Then what about the logical log? When does it come into play?
Thanks.
Transaction Log Files
Jan 10, 2005Hi,
I'm wondering if when adding another transaction log file, if the DB needs to be detached in order to remove that file. Or rather, what do you have to do in order to reduce the number of transaction log files..?
Cheers,

Purging The Old Transaction Log Files
Aug 7, 2007Hi,
In one of our DR Servers we have configured Custom Logshipping. In the folder where the .TRN files are getting copied there is a script to purge the files which are older than one day. Following is the code for the same.
@Echo Off
if exist filelist del filelist
date /t > rundate
for /f "tokens=2* delims= " %%i in (rundate) do set rundate=%%i
for %%i IN (*.trn) do echo >> filelist %%i %%~ti
for /f "tokens=1,2* delims= " %%i in (filelist) do if not %rundate% equ %%j del %%i
:pause
:Exit
Instead of removing the files older than 1 day, I need to keep 3 days transaction logs.
Being a novice I don't have much idea how to accomlish it. Can anybody help me with this?
Many thanks in advance,
Sandhya
Large Transaction Log Files
Apr 4, 2007i have a few tables using Sql Server 2005 Express. currently they are holding roughly 30-40k records in them. i have my log files set at restricted growth to 90 megs. while im not close to reaching that, i would like my tables to be able to scale up to possibly millions of records. based on that, i figure the transaction log file will prolly need to have a higher threshold (unrestricted growth). for those with experience, for tables that have millions of records, what are the average size log files i could expect.
is it a bad idea to just shrink the log file every night during off peak hours so that regardless of the amount of records i have, ill always start the day with a minimal log file?
do large log files have any effect on SQL performance?

Apr 17, 2007Hello guys and girls. I have installed SQL Server 2005 Standard Edition and I have specified that the databases should be created on the K: drive. This is okay but now I need to move all the transaction log files (.ldf) to the L: drive. I have already changed the default location for the log files to point to the L: drive and the new databases that were created after the installation have their transaction log file correctly in the L: drive but now I need to move transaction log files for the master, model, temp ... databases. How can this be done? And are there any gotchas?

View 1 Replies View RelatedLog Shipping Transaction Log Backup Files Have Wrong Timestamp
Jun 23, 2007I'm experiencing a weird problem with log shipping in SQL 2005.
I've setup Log Shipping for a production database between two sites. The standby database is being updated correctly and everything seems to be working as expected but for one detail: the name of the transaction log backups are generated with an UTC timestamp instead of my local timezone.
The the data below extracted from the backup history:
2007-06-23 17:30:00.000 D:BackupDatabasesmydbmydb_20070623073000.trn
2007-06-23 17:15:00.000 D:BackupDatabasesmydbmydb_20070623071500.trn
2007-06-23 17:00:00.000 D:BackupDatabasesmydbmydb_20070623070000.trn
2007-06-23 16:45:00.000 D:BackupDatabasesmydbmydb_20070623064500.trn
My timezone here is GMT+10.
Although it's not affecting Log Shipping, it's very confusing as the full backups have a timestamp in the local timezone!
Has anyone seen experienced something similar to this? Please see below my SQL details:

Transaction Log File Corruption When Database Files Are Placed In SSD Drive
Oct 26, 2015The MDF and LDF files are placed in SSD drive and tempdb files are placed in HDD drive. Snapshot isolation is enabled on the database. When a script is executed to insert data with NULL value to a table which has NOT NULL column, the transaction fails and then a log undo happens which fails and takes the database to suspect mode.
But when the MDF and LDF files are placed in HDD drive all this do not happen. The transaction just fails.

Jan 10, 2012I am trying to reorganise the log files on a server, (long story short they are fragmented so I want to shrink and reset the initial size and growth) and I am unable to shrink them. When I run the following:
use test
DBCC SHRINKFILE(test_log, TRUNCATEONLY)
--or
use
DBCC SHRINKFILE(test_log,2, TRUNCATEONLY)
I get the following message:
Msg 8985, Level 16, State 1, Line 1
Could not locate file 'test_log' for database 'test' in sys.database_files. The file either does not exist, or was dropped.
I get this message for every database on the server. I got the logical name of the file using sp_helpfile and have checked it against sys.masterfiles, sys.database_files and sys.sysaltfiles, all match up and confirm the name 'test_log'.
I rebooted the server last night and was able to shrink the first couple of .ldf's I tried so I presumed it was fixed. This morning when I try again i get the sanme error, I don't see anything in the SQL server or system logs that indicates a change.
I am able to add new log files and remove log files, however if I add a new log file (test_log2) and then try and truncate that file I get the same error.
SQL Server Admin 2014 :: Separate Transaction Log Files For Multiple Databases?
May 15, 2015We have multiple databases on a single instance in an OLTP environment. I have my data files on a separate SAN LUN from my transaction log files (and a few NDFs split out onto additional LUNs). I was wondering if there is a performance benefit to putting each LDF file on its own LUN? Or at least my few busiest LDFs?
We are currently on 2012, but I'm having to put together specs for a 2014 installation and need to answer this question without having an environment in which I can benchmark different setups. I just want to hear whether or not others have done this (why or why not?).
Transaction Log Huge Loading SQL Profiler Trace Files In Simple Mode
Dec 8, 2007
Hi there - can anyone advise on the following issue. We have recently performed some server side tracing on a particular SQL instance over 24hr period. We are now attempting to load these into a database for analysis. Here lies the problem.
When we are loading the profiler trace files (one at a time) into the database the transaction log is growing at an excessive rate. Even though the database is in SIMPLE mode.
We are loading the traces using the command:
INSERT INTO sqlTableToLoad
SELECT * FROM ::fn_trace_gettable('MytraceFileName', DEFAULT)
Can anyone advise how we could possibly get round this issue as we're running out of space due to the transaction log.
Thanks

"The ROLLBACK TRANSACTION request has no corresponding BEGIN TRANSACTION." This error also happens on COMMIT as well and there is a preceding Execute SQL Task with BEGIN TRANSACTION tranname WITH MARK 'tran'

Analysis :: Find Amount Distribution Across Different Transaction Types Under Spend Transaction
Jul 27, 2015I created a Calculated measure in cube something like this : ([TransType].[TransTypeHierarchy].[TransTypeCategoryParent].&[SPEND],[Measures].[Transaction Amount]). To get only spend transactions. Now, I want to slice this measure with same hierarchy to find the amount distribution across different transaction types under spend transaction. But this query behaving like the measure doesn't have relation with measure.
you can think this as below query:
WITH
MEMBER SPEND AS ([TransType].[TransTypeHierarchy].[TransTypeCategoryParent].&[SPEND],[Measures].[Transaction Amount])
SELECT NON EMPTY {SPEND} ON 0
,NON EMPTY ([TransType].[TransTypeHierarchy].[TransTypeCategoryParent]) ON 1

How do I make use of begin transaction and commit transaction in SSIS.
As am not able to commit changes due to certain update commands I want to explicitly write begin and commit statements. but when i make use of begin and commit in OLEDB commnad stage it throws an error as follows:
Hresult:0x80004005

SQL Server Admin 2014 :: Separate Data Files / Log Files / TempDB / Backups
Jan 9, 2015I proposed on a new server that we separate Data Files, Log Files, tempDB, Backups, etc. onto separate LUNS on a SAN with High Speed Solid State Drives.I was told that with the new technology with solid state SAN's that it would decrease performance and that it did not work the same way as it did when you had RAID 5's etc.I thought that if things were cared out correctly by a SAN Administrator they would know how to configure for optimal performance.

Script Task: How To Compare Files On FTP With Existing Files In Local Folder Before Transfer!
Apr 24, 2008In the first step of my SSIS package I need to get files from FTP and dump it/them in a local directory, but it's more than that, the logic is like this:
1. If no file(s) found, stop executing and send email saying no file(s) found;
2. If file(s) found, then compare it/them with existing files in our archive folder; if file(s) already exist in archive folder, stop executing and send email saying file(s) already existed, if file(s) not in archive folder yet, then transfer it/them to the local directory for processing.
I know i have to use a script task to do this and i did some research and found examples for each of the above 2 steps and not both combined, so that's why I need some help here to get the logic incorporated right.
Thanks for the help in advance and i apologize for the long lines of code!
