Transaction Log File Corruption When Database Files Are Placed In SSD Drive
Oct 26, 2015
The 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.

Hello 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?

Hi,
I'm trying to move the transaction logs of my databases to a different drive (for fault tolerance). I can create a second transaction log file for each database via Enterprise Manager but I have 2 questions:
1) If two transaction log files exist for a database which one does it use ?
2) How do I force SQL to use the new transaction log file ? (so I can delete old)
Thanks,
Tim

I recently created a program that connects to a Microsoft SQL database that was stored on my computer and it worked fine. As soon as I tried to connect to the same database via a network drive I got an error stating that "The file Y:Filename.mdf is on a network path that is not supported for database files.". I can't seem to get it to work, if anybody has any ideas what I'm doing wrong I would appreciate your help.

Hello -
I have a database server with over 300 databases. I want that MS-SQL Server should daily report me the sizes of SQL databases along with Transaction log files by sending me an email on my address.
How can I do that. Does someone have any script which can help me to do that.
Any help will be appreciated.
Kind Regards,
Rubal Jain

I am trying to move a log file from one drive to another.
What I have done is add another file to my file group. So now my log has a file on the 'e' drive and one on the 'f' drive. I now want to remove the file on the 'e' drive. I have emptied the file on the 'e' drive. When doing the command:
ALTER DATABASE Uniprodruntime
REMOVE FILE m_rk_runtime_log
I get the following error message..
Server: Msg 5020, Level 16, State 1, Line 1
The primary data or log file cannot be removed from a database.
I have also gone into enterprise manager and tried to delete the file and it does nothing.
Has anyone run into this?

Hi,
Just got a new box and want to fully optimize the server. I was contemplating where to put the transaction log? I have 2 drives:
Drive C: 30 Gig(Operating System)
Drive E: 180 Gig(Database file)
I'm planning to build the database in Drive E:, but am leaning to put the transaction log in drive C:. Do you think it's a good move? I want to separate the log and data files, but Drive C: is host the operating system. Do you think it would be wise to partition drive C: and put the operating system on one partition and the Transaction log on the other? Does it enhance performance in anyway?
Thank You!
Joe

I just upgraded SQL6.5 standard(Installed 7.0 and ran Wizard to upgrade dbs) to SQL7.0 by running the exe file.
It turned out that the MSSQL7 folder is follen on Drive C instead of Drive D which is what I wanted. When I was running the upgrade exe file, there was no prompt to ask me the right path.
How could I have the MSSQL7 folder installed on D drive?
Thank you for help

All,
I'm writing to ask if anyone knows whether or not MS SQL server stores in any system tables the association between a database and the drive letter/directory path where its corresponding MDF/LDF files are located.
Thanks,

Hi all,
I downloaded and ran AdventureWorks.msi into my SQL Server Management Studio Express (SSMSE) one year ago.But I did not know how to attach it to my SSMSE then. Last week, I deleted it from the "Add or Remove" of Control Panel and I downloaded the new AdventureWork.msi and installed it my SSMSE. Today, I tried to use the Database Explorer of VB 2005 Express for the first Stored Procedure programming. I clicked on AdventureWorks.mdf and I got the following error: One or more files do not match the primary of the database. If you are attempting to attach a database, retry the operation with the correct files. If this is an existing database, the file may be corrupt and should be restored from a backup. Cannot open user default database. Login failed. Login failed for user 'CENADe1enxshc'. Log file 'C:Program FilesMicrosoft SQL ServerMSSQL.1MSSQLDataAdventureWorks_Data_log.ldf' does not match the primary file. It may be from a different database of the log may have been rebuilt previously. Please help and advise me how to correct this problem.
Thanks,
Scott Chang

Howdy y'all! :)
I have been instructed to move a large database we have on one of our servers off the current drive (local RAID-5 driveset in the server) to a EMC "drive" (logical drive, off-server).
I know one option is to back up the database, delete the database, re-create the db using the new drive for data/log files, then restore the database.
However, I was wondering if it would be better to just detach the DB, move the data/log files, then reattach to them?
Is it half-doz of one, and 6 of the other?
How should I go about this dastardly deed?
Off to poke around in BOL, but thought I would post first in case it's an incredibly easy answer for y'all
Thanks!

We have a cluster with two nodes and two instances of SQL Server 2012 Standard Edition running on them. Volume W: is a Fusion-IO card.
On one of these nodes a lot of database names are showing up in the resource monitor as *.mdf files (W:0MSSQL1…).
How and why SQL Server is using these files? They only show up on one of the nodes having more load.
Volume I: is the volume where the transaction log is written so we can explain these files.

Documentation that supports the placement of Tempdb files on the root of a drive, i.e T: instead of T: empdb. I am positive this is not a best practice, but when challenged could not find any documentation that would support that view.

Dear all,
What I want to do is to backup my database through the SQL script, when the backup is successful, the .bak file is saved in my local harddisk. After that, I used the XYRunProc to execute a "copy" command to copy the .bak file to a remote server.
However, when I want to restore the database using the .bak on the remote server, I found that the .bak is corrupted. This problem does not exist if the file is copied to the remote server manually (click copy on local server and click paste on remote server).
Do anyone know what's the problem of this? This really made me very frustrated. Hope someone can help me, thank you very much!
Regards,
Strike

I have a database [CarlosDB] that currently has it's .MDF on E: and I need to move the x2 .NDF data files off C: to E:data using a single T-SQL statement:
Code:
database_id file_id db_name disk_path status size read_only
----------- ----------- --------------------------------------------------------------------------------------------------------------------------------
7 1 CarlosDB E:dataCarlosDB.mdf ONLINE 384 0
7 2 CarlosDB_log L:logsCarlosDB_log.ldf ONLINE 128 0
7 3 CarlosDB_2 C:sqlCarlosDB_2.ndf ONLINE 128 0
7 4 CarlosDB_3 C:sqlCarlosDB_3.ndf ONLINE 128 0
(4 row(s) affected)
Looking at the file configuration above, what would be the most logical way as a DBA / SQL Server 2014 Std to move the NDF files to live w/ the MDF file using:
Code:
EXEC master.dbo.xp_cmdshell 'copy c:sqlCarlosDB_2.ndf e:dataCarlosDB_2/ndf'...
but cleanly using a single T-SQL statement? properly formatting a single T-SQL query to use the xp_cmdshell system stored procedure.

Hello,
I need to move all log files for my SQL 2005 databases to another drive. I don't wish to shrink the files, I need to move the logs to another drive spindle. I did find an article (Article ID: 224071) that describes moving both the database and logs using sp_detach and then sp_attach. What is the best way just to move the logs to another drive on the same server, and that keeps the databases in their original location?
Thanks.

I have two databases on a Production Server that I want to Log Ship to a Test Server. According to the sys.master files the physical File Location is on an E drive. Early attempts at Log Shipping these two files error'd out due to space issues on the E drive (one Log Shipped and then one err'd out). I was subsequently informed from the server group that they would prefer that I Log Ship these two database files over to the M Drive where more space is available. In fact, they modified the Server Properties / Database Settings / Database Default Locations (for Data and Log) to the larger M drive (I'm not really sure why they just don't increase the E drive space but there is proabably a good reason).
Okay, so now my problems have been solved. Easy enough. Now I deleted the successful Log Shipped database and started from scratch. However, as before, one db restored and one failed (due to space issues). Apparently, both db are pointing towards the E drive. How is that possible?
So here I am with one successful database and the normal sys databases pointing to the E drive. What is the best way of approaching this move to the larger and preferred M drive?

We have a package that is using a ForEach loop container to access files on a network drive. For some reason I am getting a message that the ForEach enumerator is empty and did not find any files that matched the pattern. For the pattern I left the default *.* for testing purposes. I have specified the file folder as \remoteserverfilesharesubfolder and also as \remoteserverc$filesharesubfolder and have gotten the same message. However when I map a network drive and set the file folder to the network drive it finds the files. Is this a permissions issue?
After I finish processing the file I want to move it to a new directory. Once this is deployed in production, the package will not be running under a domain account and probably won't have access to the network folder. Is there any way to specifiy in the connection manager itself that it should use a specific account to access the folder?
TIA,
Sabrina

I haven't found the definitive answer on how or if this can be done without removing replication. I'm thinking ALTER DATABASE modify_file is the way to go. Anybody know if this will work or a better way to go about it?

Being a very novice SQL Server administrator, I need to ask the experts a question.
How do I go about moving a database from 1 drive to another? The source drive (C is local to the server, but the target drive (E is on a Storage Area Network (SAN), although it is still a local drive for the server. I want to move the database from C: to E:. Can someone provide me with instructions?
Thanks,
Rick

Hello.
One of our hard drives has crashed and as a result we have lost our master mdf/ldf & user db mdf/ldf files. It's not that a critical system by any means, but if the hard drive crashes and the master mdf/ldf files & user db mdf/ldf are lost, is there any way of restoring the system?
I'm thinking we probably need to re-install Enterprise Manager completely, and re-install the user db from a backup.
Any advice/suggestions would be much appreciated.
Thanks in advance,
