Accidentally, I've managed to have this as part of a Create Database:
... FILENAME = N'C:MSSQLData\ estdb_Log.LDF' ...
, notice the triple backslash. The Create Database statement works fine,
and sp_helpdb says the log file name is:
C:MSSQLData\ estdb_Log.LDF
I noticed the MSDOS command prompt also allows multiple backslashes,
they're reduced to one when performing the command and I guess
SQL Server does the same thing, so no problem so far really.
But is it supposed to work this way? Quite confusing, isn't it?
Hello all. Before my arrival at my current employer, our consultantsphysically set up our MSSQL 7 server as follows:drive c: contains the mssql enginedrive d: contains the transaction logdrive e: contains the data filesNo filegroups were set up and the data files consist of only 1 largephysical file. Currently, our data file is >10GB. When I was trained onthe physical aspects of sqlserver, I was told to never create physical files[color=blue]> 2048MB each. If I did, I could expect inefficient physical storage of[/color]data and slower performance (due to the OS).Our server has 2 RAID-5 arrays. Drive c: and e: are located on the firstarray and drive d: on the second. We're running Windows 4.0 NT Server SP6with NTFS.Can someone comment on the use of 1 single large data file vs. more smallerdata files?
I have used the copy database wizard, but I realized I had forgotten to shrink the transaction log file. So I canceled the wizard. My database, detached by the wizard, has now disappeared. The mdf file is still there, but when I try to attach it manually I get the "create file encountered operating system error 5 while attempting to open the physical file..." error.
Unable to open the physical mdf file or log file because it is being used by another process
I am trying to write a Windows Application using ASP.NET 2.0, C#2005 EXPRESS, and SQL 2005 EXPRESS.
I had followed the introductory video to create a connection to the Database using Windows Authentication, and use the wizard to create a dataset and checking all the tables in the database.
After that I dragged a table from the data source created from the above process. The Details Grid so created is able to perform update, delete and addition of records.
But when I went back to the database at my PC I wasn€™t able to connect to the database. And if I opened the database first and then load the windows application and perform some database operations and went back to the physical database I wasn€™t able to open the tables in the database.
The error message is that the physical database connection cannot open the .mdf file or log file because another process is using the database. I guess it refers to the Windows Application.
Is this normal? Will it have any implications after the application is deployed? I suppose that there isn€™t a scenario where a Windows application and a physical process will access the database at the same time.
Will appreciate some feedback and advice on this scenario and whether it is a problem.
Hi, i'm trying to interface a c# application with an sql database created with Visual Web Developer Express. I have published the site (and the db) on iis 5 (xp pro). Everithing goes fine on accessing the database from internet,but when i try to connect the db while it's opened with my c# program i keep an error in the sqlconnection open command: Unable to open the physical file "C:myApp_Datamydb.mdf". Operating system error 32: "32(The file is in use by another process.)". My connection string from webconfig: <add name="MYDBCS" connectionString="Data Source=.SQLEXPRESS;Database="C:myApp_Datamydb.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True" providerName="System.Data.SqlClient" /> .....and the connection string for the c# program: "Data Source=.\SQLEXPRESS;Database=c:myapp_datamydb.mdf;Integrated Security=False;Connect Timeout=30;User ID=abc;Password=abc;Trusted_Connection=False;"; I have used a user to connect the database because there was a conflict trying to open the db with Integrated Security=True.
Does anyone have an idea where is the error? Many thanks Max
Hi Everybody, I like to compute the actual physical database file size using queries.
From the EM database properties, the file size shown is not matching with the master..sysaltfiles.size
Ex. Actual file size is 12MB and 1MB for MDF & LDF respectively. 'sysaltfiles' shows 1464 & 96 resp. Since they are shoing it as 8K Pages, 96*8 = 768KB is not matching with 1024KB for the LDF file. Is there any overheads (additional space from the physical file for file headers) allocated?
I have been trying to use DMO(C++) to backup a database and then restore from that backup to a new db name AND physical data and log files, with no success. I have been able to successfully restore the backup to the same database and change the physical file names using the RelocateFiles property on the Restore object, but not change both. Any help would be greatly appreciated.
Due to running out of disk space and reducing I/O contention, I plan to seperate data files and log files to different disk arrays.
My plan is to - detach all databases - copy log files to another disk - attach all databases
The total size of log files is about 60GB. It becomes a problem becasue it spend too much time passing files. To reduce down time, is there any way I can do?
Can I just create new log files and remove the current files by using sql management studio?
Scenario : I have VC++ 2005 Express IDE open and use the database explorer to browse tables in a database. Then I open SQL Server Managament Studio Express and try to browse the same database. I get "Unable to open the physical file ... The process cannot access the file because it is being used by another process".
What is this "other process" that is trying to open the file? I thought the whole point of a database server was that clients talk to the server, and the server accesses the physical file. So only one process should be accessing the file. Do VC++ IDE and SSMSE work directly with the physical file, or do they channel their requests, etc. through the server.
Hi, I've just finished creating my first ASP.NET website. I created it on my laptop and it works perfectly, but I'm having some problems deploying it to my web server (PC).The site works ok, but when I try to log in to my client area, I get this error: "Unable to open the physical file "c:inetpubwwwrootONeillStrataApp_Dataaspnetdb.mdf". Operating system error 5: "5(Access is denied.)".An attempt to attach an auto-named database for file c:inetpubwwwrootONeillStrataApp_Dataaspnetdb.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share." I've searched far and wide for a solution and have read many articles, but none seem to be able to fix my problem. I've tried using that SEUtil tool, but that didn't work, I've made sure the App_Data directory on the web server isn't read only (the read-only checkbox isn't ticked, but it DOES have that little green square which I can't get rid of), I've assigned the ASPNET user as a db owner and that didn't work and I've manually attached the database to the web server's instance of SQL Express 2005.When I launch the solution in VS2005 on the web server, I can browse through the database and see the tables and data etc, but when I try to run the application, I get that message above... Surely it shouldn't be this hard to get it going?Any help would be massively appreciated.

I am working in a C# database application quick test where I basically use two types of access to an SQL Server Express database. In the first part of the code, I use the traditional connection declaring a SqlConnection. When I just use only this kind of connection I do not have any problem. The issue starts when I access to the same database using Data Bindigs at the same time. When I start the application I got and error as soon as the instruction goes to open the data base connection. The reported error is "Unable to open the physical file "<Niños.mdf>". Operating System Error 32: (Process does not have access to the file because is being using by another process)"
For additional information my connection string is:
I am trying to attach a database to SQL 2005. This database has not previously been attached. I have only just installed SQL.  I get the following message: Unable to open physical file "C:ArrowSQLArr@DataArrow_data.mdf" Operating system error 5: "5(error not found)" (Microsoft SQL Server: Error 5120)".  I have loaded SQL and the database fiel and directory with the same user account which is a local administrator on this machine. I have checked that I have read/write access to the file.  The machine runs Windows Vista Business. SQL has SP 2 loaded. What causes this?
We have a very severe issue in our production, and this is very very ugent to fix this issue, there was a job started on server on 10th October, 2007, for backup of database of 3.2 TB, which caused this issue on 18th October, 2007. I cancelled that job and even restarted the server, but still there is same issue on the server.
I am using this command to expand the physical file,

I have a an asp.net application running under IIS. this application is using two folders, the virtual directory under C:Inetpubwwwroot and the application phisical folder at C:. I want to manage this applications .mdf database using microsoft sql server management studio express(iam running sql express with advanced services) which means i have to attach the database to Ms sql server managemet studio express tool. What i dont know is if i should attach the .mdf file in the physical folder's App_Data folder at C:myapplicationFolderApp_data or the .mdf file in the virtual directory under C:InetpubwwwrootMyapplicationFolderApp_Data I dont know which of the two i should attach. Where exactly is the running database, the .mdf file in the physical folder or the .mdf file in the virtual directory under wwwroot.
We are trying to attach a database in Sql Server 2005 Express on Windows Vista.It will Show the following Error.
"Unable to open the physical file "Test.mdf". Operating system error 5 :". And then we installed the SQL Server 2005 Service pack 2. This error again comes.Could you please give me the steps to resolve the problem.
I had to to relocate the database log file and I issued an Alter database command but by mistake I put a space in the file name as below. The space is at the beginning file name. Now I am unable get the database loaded to SQL Server. The database has 2 replications configured, so deleting and re-attaching the database means the replication needs to be re-configured. Is there an alternative way to issue a command to update the database FILENAME ? Not sure if this can be edited in master database (sys files).
ALTER DATABASE [User_DB] MODIFY FILE (NAME = User_DB_log, FILENAME = 'I:SQLLogs User_DB_log.ldf') GO
I need to move specific files from a server to another server on a monthly basis. Â There are hundreds of files that are in the source directory and I need to move approximately 40 of those to the destination server. Â I would like to easily add or delete the file list as needed. Â I have seen where several variables were created for for each file name (and one for the path) and the ForEach Loop would go through them. Â With 40 or more I was thinking that I could make a connection to an Excel spreadsheet or text file with a record for each file name and read in and and move to the next record and make that value become the content of a "FileName" variable. Â Then if I wanted to add another file name I could just add another record to spreadsheet/text file or remove and the package would handle automatically....
Why shrinkfile empty file does not redistribute data evenly in the primary file group with multiple files:
Please run the script attached to see what the end result is.
This is what I set up last night on my test machine.
1) Create database [FGTest] size 200MB 2) Create table called TEST on primary 3) Insert 40MB of data into test 4) Create another file group called temp in primary size 200MB 5) Shrinkfile('FGTest',emptyfile) so that all data is transfered from FGTest into temp file group. 6) Add another 2 files called DATA2 and DATA3. Both are 200MB. 7) We now have 3 empty files that I want data distributed evenly on. FGTest, DATA2 & DATA3 8) Shrinkfile('temp',emptyfile) to move all the data from temp over the 3 file groups evenly
I would expect at this stage to have the following:
FGTest = 13MB, DATA2 = 13MB, DATA3 = 13MB
(40MB of data over 3 files should be about 13 MBish in each file)
What I actually end up with is this:
FGTest = 20MB DATA1 = 10MB DATA2 = 10MB
It looks as though SQL Server is allocating 50% of all data to the original file and then 50% evenly over the remaining files in PRIMARY.
I have one of our production Accounting Databases starting from 2 GBnow grown into a 20 GB Database over the period of a few years...I have been getting timeouts when transactions are trying to updatedifferent tables in the database.. Most of the error I get are I/Orequests to the data file (Data file of the production dbAccounting_Data.MDF).I would like to implement the following to this Accounting database.I need to split the Data file into multiple files by placing some ofthe tables in different file groups. I have the server upgraded to beable to have different drives in different channels. I can place thesedata and log files in different drives so it will be less I/Oconflicts..I would like to have the following file groups..FileGroup 1 - which will have all database definitions (DDL).FileGroup 2 - I will have the AR Module tables under here..FileGroup 3 - I will have the GL module tables under here..FileGroup 4 - I will have the rest of the tables under hereFileGroup 5 - I will like to place the indexes under here....Also where will the associated transaction files go?I would like to get some help doing this. Is there any articles / helpavailable that I can refer to. Any suggestions / corrections/criticisms to what I have mentioned above is much appreciated...!Thanks in advance....
partition with single file group or multiple file group which one best.
we have some report running from partition table, few reports don't have any partition Key and after creating 400 partition with 400 file group it is slow.what is best practices to crate 400 file group or single file group.
hi, I am new to this technology. can anyone pls help me.can anybody tell me what is physiacl file and source physiacl file wat are the attributes of physical file and source physical file.and how do we identify the uniqueness of a job.
I know that the File connection can be used in the File system task and Flatfile connection can be used in Flat File source or destination, but I don't know which Task or Source/Destination can use the Multiple File connection and Multiple Flatfile connection. Thanks
How can I split this incoming file into separate txts. I want to cut out each Header/detail row section into a new txt. What I mean by header/detail row:
incoming txt file:
http://www.webfound.net/split.txt
basically want to cut out each section like this:
http://www.webfound.net/what_to_cut.txt
http://www.webfound.net/rows.jpg
and a kicker...each new txt name must use a certain field (based on x numbers in header row) followed by another field whcih is the date form the header row. somethign like this:
I need some hand holding here, it's my first time trying to do something so complicated in SSIS 2005. If I can first just get the txt split into multiple, that would be a big help.
Can anyone inform me how I would go about merging or combining 2 or more physical database files into 1. For example, suppose you have the following files out on your server:
Hi! I have an SQL server installation with a 6.5GB database online at a particular location. I need to move the Database to another location which is a 1000 Miles away.
I have an additional physical Server at the other location which I can use to Sync the database from the original location. Can anyone please guide me to the best strategy to sync the database from the original location to the new location with minimum downtime??
Can anyone explain to me how a column defined with a "bit null" datatype is physically stored in MSSQL? Is it stored like a "tinyint null" physically? In other words, how many bytes on the row on the page does a "bit null" datatype consume (assuming a non-null value 0, or 1 is the current value).
Is there any good documentation about the physical storage layout for a data page?
