Log File (.ldf) Does Not Match The Data File (.mdf
Nov 3, 2007
Hello, i've installed DotNetNuke on my PC and used Visual Studio 2005 to create an SQL Server 2005 database using the "add new element" feature in the Solution Explorer, which works fine, but sometime when i log back in and bring up the DNN web page i will get some kind of database error, ie below:
The log scan number (49:361:1) passed to log scan in database
'C:DOCUMENTS AND SETTINGSBOBLOCAL SETTINGSTEMPVWDWEBCACHEIBM-E24B88DE7DD_DOTNETNUKEAPP_DATADATABASE.MDF' is not valid. This error may indicate data corruption or that the log file (.ldf) does not match the data file (.mdf). If this error occurred during replication, re-create the publication. Otherwise, restore from backup if the problem results in a failure during startup.
Could not open new database
'C:DOCUMENTS AND SETTINGSBOBLOCAL SETTINGSTEMPVWDWEBCACHEIBM-E24B88DE7DD_DOTNETNUKEAPP_DATADATABASE.MDF'. CREATE DATABASE is aborted. (Microsoft SQL Server, Error: 9003)
Can you please tell me if there is a way i can sync up the (.ldf) file with the (.mdf) file somehow as this error will sometimes happen when i havn't made any changes to the database, or at least i think DNN hasn't, maybe it does but it's not obvious.
Thanks very much for any suggestions or references!

I've just applied CU7 to a set of SQL2005 SP2 servers with no problems, except on one server.
I've now fixed the problem, but couldn't find description of it elsewhere so post it here in case it helps anyone else with the same problem.
Here's the problem I had. The server is Windows 2003 with two instances of SQL 2005 SP2 (9.00.3186)
1) Ran the patch (SQLServer2005-KB949095-x86-ENU.exe)
2) C: drive ran out of space whilst patch was running against instance A
3) Cleared down space on C: drive
4) Patch had hung, after 45 minutes of no activity I killed it
5) Re-ran patch, it reported instance A as upgraded already and just upgraded instance B
6) After reboot instance A failed to start. Instance B started with no problem.
The service was failing to start with the following recorded in the log:
Server Microsoft SQL Server 2005 - 9.00.3239.00 (Intel X86)
[€¦]
spid5s The resource database build version is 9.00.3186. This is an informational message only. No user action is required.
spid5s Error: 5173, Severity: 16, State: 1.
spid5s One or more files do not match the primary file 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 corrupted and should be restored from a backup.
spid5s Error: 5173, Severity: 16, State: 1.
spid5s One or more files do not match the primary file 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 corrupted and should be restored from a backup.
spid5s Log file 'C:Program FilesMicrosoft SQL ServerMSSQL.2MSSQLDATAmssqlsystemresource.ldf' does not match the primary file. It may be from a different database or the log may have been rebuilt previously.
spid5s The log cannot be rebuilt when the primary file is read-only.
spid5s Error: 945, Severity: 14, State: 2.
spid5s Database 'mssqlsystemresource' cannot be opened due to inaccessible files or insufficient memory or disk space. See the SQL Server errorlog for details.
I think that the patch must have got part-way through instance A, enough to mark it as being patched, but not far enough to patch the mssqlsystemresource system database (note the version numbers in the log above - 9.00.3239 vs 9.00.3186).
The hotfix log records an error opening the registry, but the detailed log was overwritten by the subsequent (successful) run of the hotfix so there€™s no more detail available.
To fix this I copied in the mssqlsystemresource mdf and ldf files from instance B (which wasn€™t patched the first time round, and was subsequently patched successfully). From what I understand mssqlsystemresource is read-only and holds copies of system sprocs etc, so a copy will suffice. Plus I am assuming the SQL Server is clever enough to complain if it€™s not happy with the instance of the file.
Note that the problem recorded elsewhere for this error, where mssqlsystemresource or other system DBs have been moved from their original installation folders, was not the cause here.
Not sure if this is the 'correct' fix, but it got Instance A up and running. Obviously YMMV

For a database, we have 4 data files in a particular file group and the file sizes are almost 70 GB each.
Do I come across any performance issues if I create/pre-allocate an additional data file in the same file group so that the existing files don't grow too much?

For example, I have a 1 GB data filewith 1000 byte header. Except for first 1000 bytes, rest of the data isgood for BULK INSERT.Thanks in advance.

I've production sql server 7 sp3 on windows NT. I had a 8GB data file ofwhich 5GB were used and 3GB were unused. I wanted to take back the unused3GB.So I did the following with EM GUI:1. I tried to "truncate fre space from end of the file". Didn't truncatethe file. I believe there was no empty space at the end of the file.2. Next I chose the option to "shrink file to 5GB". And to my horror thedata file instead of taking just 5GB took the empty spaces also and the sizeof the used data file went to 8GB.Any idea what's going on?TIA,SP

hi all;
1. Excel file Source--> monthly Revenue details
2. Derived Colum Transoformations
3. Oledb Destination
its my flow in one of my packates (ETL job)
Excel file contains monthly revenue details, i wanna import the excel data to my database staging table, so i've created the package.
its working fine...
Problem
if we change the new data for the next month and running the package its not running;
the same file, same format, only we delete the contents, of the file except first row of the excel sheet,
and pasting the new data;
new data is coming from Oracle DataBase in the form of excel sheet ( manually they will copy the data and sending to us)
i open that package in design mode and while double clicking the excel file source it says <column name>'s Meta Data needs to be synchronized
Do you want to Fix this issue automatically with the available external column's meta data
Clearly noted that its a data type issue; i have changed the corresponding data types as it is in the previous Excel sheet which is equivalant to the Table its copying to.
now the package is running with validation warnings, External Column "Invoice Amount" needs to be updated...etc. some 2 or three warning messages i can able to see in the package Execution wizard,
ok, i'm ready to accept these warnings, and i want my package running from my server;( packages had been deployed in to the Centeralized server; every time if we want to run the package, we have the asp.net webpage, that is executing the package in an On_click event)
The package is not running from the server, its due to the meta data change in the Excel file( i guess)
please suggest me some guide lines to resolve this meta data issue, i want my excel sheet meta data should not change when we have new updates in it;
otherwise suggest me some solutions that i can validate the excel sheet before running the package and testing whether the data is in correct format or not? its a kind of Data Profiling activity;
i know its some what crazy, but i need to maintain the system with permanent solution, instead of facing this meta data mismatch issue!!!
some what lenthy explanation--> its needed for my dear powerful microsoft responders. i think i 've explained my problem clearly, if i don't let me know your queries, i'll try my level best.

Hi all,
In a foreachloop, I am inserting records into a flat file which is working fine. But the thing is that as the file grows, it takes longer for it to locate the EOF(End of File) of the flat file so as to insert the records.
I have around 70-100 lines written to the file at each loop and there are more than 20k records to be looped. wihich means that at the end I should be having 1400k - 20000k line in the text file.
One solution would be to insert the records at the start of the file itself so that it does not has to lookup the EOF each time before writting.
Another would be to generate separate files and then merge it.
Any idea how can this can be done?
Beside this I have to zip the file and then SFTP to a given address.
Any suggestion or help would be welcome.
Rdgs

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.

Hi all,
I have a serious problem:
I created 1 database with 2 file group : 1 primary and 1 index.
- Primary file group includes 1 data file (*.mdf): store all tables
- Index file group includes 1 index file (*.ndf): store all indexes
Most of indexes are non-cluster indexes
After a short time using, data file is 2GB but index file is 12 GB.
I do not know what problem happened in my database.
I have some questions:
1/ How so I reduce size of index file ?
2/ How to know what is stored in index file?
3/ How to trace all impact to index file?
4/ How to limit size growing of index file?
Thanks in advanced

We have a large 'History' database that is currently about 4.5TB, with most of that in a datafile that is 4.2TB. We wanted to stop growth on the one large data file and have SQL Server allocate new data to the other data files, but this throws an error when we attempt to change the MAXSIZE settings:
ALTER failed for Database 'History'
MODIFY FILE failed. Specified size is less than or equal to current size.
The SQL Server is saying we can have a max size of 2TB, and anything over that is blocked. Since this is being blocked, the file continues to grow.
Is there any way to cap the growth of the 4.2TB file and not allow any more data to be written to it?

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.

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,

I need to import data from csv-file to sdf-database (SQL CE 2.0).
When I copy the csv-file to my mobile device, it thakes more than 1 hour. The sdf-File later has a size of 20MB.
If I create an sdf-File (SQL CE 3.0) on the desktop, it just thakes a few minutes.
Is it possible to create an sdf-File (SQL CE 2.0) on the desktop legally?
My clients don't want to by the SQL-Server, because it should be an inexpensive solution.
Or is there another way to create the database with more performance?
Thanks

Currently have a single hard coded file path to the SSRS config file which parses the file and provides the reporting services web service url. Â My question is how would i run this same query against 100s of servers that may or may not share the same file path as the one hard coded ?
Is there a way to query the registry to find the location of the config file of any server ? which could be on D, E, F, H, etc.Â
I know I can string together the address followed by "reports" and named instance if needed, but some instances may not have used the default virtual directory name (Reports).
Am I going about this the hard way ? Is there a location where the web service url exists in a table ? I could not locate anything in the Reporting service database. Basically need to inventory all of my reporting services url's.

Greetings, I have just arrived back into the country (NZ) and back into ASP.NET.
I am having trouble with the following:An attempt to attach an auto-named database for file (file location).../Database.mdf failed. A database with the same name exists, or specified file cannot be opened, or it is located on UNC share.
It has only begun since i decided i wanted to use IIS, I realise VWD comes with its own localhost, but since it is only temporary, i wanted a permanent shortcut on my desktop to link to my intranet page.
Anyone have any ideas why i am getting the above error? have searched many places on the internet and not getting any closer.

In the full recovery model, if i run a transaction that inserts 10MB of data into a table, then 10 MB of data is moved in the data file. Does this mean then that the log file will grow by exactly 10MB as well?
I understand that all transactions are logged to the log file to enable rollback and point in time recovery, but what is actually physically stored in the log file for this transactions record? Is it the text of the command from the transaction or the actual physical data from that transaction?
I ask because say if I have two drives, one with 5MB/s write speed for the log file and one with 10MB/s write speed for the data file, if I start trying to insert 10 MB of data per second into the table, am I going to be limited to 5MB/s by the log file drive, or is SQL server not going to try and log all 10 MB each second to the log file?

I am testing some maintenance tasks sql commands such as index rebuild, index reorg, update statistics and db integrity check on a SQL Server 2014 Database. This is a new non-production vendor database (DB Size 500 GBs, Log Size 25 GBs) which eventually will be created in production. Currently, it is in full recovery model and without log backups. The database has a whole lot of indexes. I am just trying to rebuild and reorganize all the indexes (that need it), in addition to trying to get an idea of how long these maintenance task will take and the space needed in the log file to complete these tasks/commands. I would like to execute these tasks manually (the first time) to gather the duration and space required information. Eventually, I would probably schedule a weekly job to perform this maintenance.
I ran the index rebuild task on the database and noticed that the log file grew by over 50 GBs. I killed the process and truncated and shrunk the log file back down.
1. Does the index rebuild, index reorg, update statistics and db integrity check commands all use the log file?
2. Does Indexs Reorg have less impact on log file then Index Rebuild?
3. Should a truncate log and shrink log file be performed after these maintenance commands?
4. Should a full database backup be performed after these maintenance commands? Or before the maintenance commands?
I have read and understand that shrinking is not good for the database (could lead to more fragmentation and more data file growth when data is added) and I know about rebuilding indexes when fragmentation is GT 30% and reorganizing indexes when fragmentation is GT 5% and LE 30%.
Since this is a non-production database maybe I should set the recovery model to simple, run the maintenance commands and leave the database in simple recovery model unless the vendor needs it in full recovery model for some unknown reason.
5. With the simple recovery model the log file should be reused in a circular manner and not grow during these maintenance tasks. Is this correct?
