Hello everybody.
I have SQL2000 sp3 standard
with 50 db's
All db set for full recovery
and autoshrink
Backup done with Tivoli
full backup once a week
log backup done every 12 hrs
Problem .. shrinking logs
every 20 min I run job
DBCC SHRINKFILE (My_db_logFile) for every db
70% of the time I am getting
message similar to
-------------
Cannot shrink log file 2 (Wholesale_Log) because all logical log files are in use.
--------------
1. I checked with sp_who2
The is no activity on db 'Wholesale_Log' or any other db returning "Cannot shrink..."
Why i getting "Cannot shrink ..." ?
even if job runs right after backup of the log files ,I still have messages.
Damn, people, how to shrink log file. I've tried several times with DBCC SHRINKDATABASE ( database_name , TRUNCATEONLY) and DBCC SHRINKFILE (log_name, final_MB, TRUNCATEONLY)
and the log still is _untouched_
I have got big table, about 190 mln records (15 GB) and after simple update the log is very big but unnessesery.
we are running on sql server 2005 and in some of our production databases the log files are twice as bigger than the data files. we are planning to reduce the log file size. I saw the option on the management studio to shrink the log file. I just have some questions on this. as long as we are doing on the production server can we do that while the database is online or do we need to take the database offline? any help would be appreciated. Thank you!
I have a database file LEAR_Index(yes, it hold index data) from a havehave recently removed a bunch of data.It is about 120 Gb, 100Gb of which is not used. I wan´t to shrink thefile to lean 30-40Gb.I´ve been trying this:dbcc shrinkfile('LEAR_Index',40000)But to no apparent avail; the file did not shrink.I´ve tried using enterprise manager for this but it consistenlycrashes when performing this operation.#Any thoughs, idear as to what i might be doing wrong?
Hi, I have some doubts about Shrinking databases or files. while shrinking a file, I learned that we are alllowed to shrink more than the minimum size of the file, does not it bring damage to the data in that file ??
We have a database in production which has free space about 200 GB in Data files and Index files, I want to shrink Data files and Index files.If I do incremental shrink in daytime does it hurt the performance of the database or please advise what is the best practice.
I've been tasked with taking over the support for a client's SQL Serverdatabase. I'm not a DBA by profession, I'm a software developer whouses SQL Server as a database designer.The clients have reported that the server is running out of disk spaceand examination shows that the log files for several of the databasesare at 5Gb or more.After reading around the subject I suggested the following sequence ofoperations:-- Select the name of the database you want to shrinkUSE MyDB-- Dump unwanted transactionsdump tran MyDB with truncate_only-- Get the name of the logfileSELECT * from sysfiles-- Having examined the rows returned by this use the log file....-- Shrink the file to required size (in MB)DBCC SHRINKFILE('MyDB_log', 10)Is this a reasonable approach? Please bear in mind that I'm pretty newto this, and I have many other tasks to do besides manage the server.A previous DBA has set up good maintenance plans etc. so everything isbeing properly backed up (well, I think it is)If this IS a good approach, would it be reasonable to do this on, say,a monthly basis as a scheduled job? Obviously the stepSELECT * from sysfileswhich gives us the physical name of the log file would be removed andthe job would operate explicitly on each log file for each database inturn.Many thanks for reading.William Balmer.
I have dataware house database and it's size is 2 TB with simple recovery model.I want to reduce it's size because everyday before loading table gets truncate.Is it best practice to shrink the datafiles?database having 5 data files and one log file.what is the best way to reduce?
I have a no of databases in full recovery model whose files are many times their datafiles. It is because these databases were copied from the development servers and in the development servers they were not taking the transactional log backups although once in the production server it is ensured that a transactional log is taken once in a day atleast. I plan to shrink the logfiles using the dbcc commands. However I am afraid that it may lead to severe defragmentation and performance hits.
We are using Sql Server 2008R2 enterprise edition which is clustered.
In this context my questions are:-
1)What is the best course to do the shrinking of log with out defragmentation?
2)Can I do the shrinking when the database is in use or is online in production?
3)Will the shrinking of the logfile improve the performance in any manner like that of the i/o operations or paging?
4)Can I do the shrinking of the log files alone without the shrinking of the corresponding data files?
I am using Sql Server 2012 in always on configuration with multi subnet failover clustering. Size of data file has suddenly increased, i dropped all the unnecessary table from database three days back. day before yesterday i tried shrinking data file using DBCCÂ command but it is taking too much time. is there any other option for deallocating the space.
I have a database which has log file size 300 GB. As the drive is filling up i need to clear the space on the drive, for that i have to shrink the log file.Â
Unfortunately i dont have option to take backup of the database.And i am not able to shrink the file now. Is there any way to shrink the log file with out taking backup of it ?
It works remotely if I run it via command prompt. But when I add this to a TSQL job on my remote SQL instance, it runs without deleting anything. What I'm missing?
I've written a custom script to delete backup files from location. But unable to modify now to count the number of files are deleted. How to modify the script...
/* Script to delete older than N days backup from a specific directory */
USE [db_admin] GO IF OBJECT_ID('usp_DeleteBackup', 'P') IS NOT NULL DROP PROC usp_DeleteBackup GO
Currently we use a SQL maintenance plan to do a full backup of all our databases daily (about 40 databases on our production server). As you can imagine, this eats up disk space quickly so currently we manually zip the backup files and/or move them to an archive drive. I considered writing an application to walk through the backup folder structure and zip any .bak file it finds, but I know there are some third party tools out there that will backup/restore a MS SQL database. I was wondering if any of these also zip the backups once they are created. Any recommendations or suggestions are welcome.
I scheduled automatic backup process but its only showing backup of the only one .sql file in the backup folder. Other created .sql files are not backed up. Why is it so?
I want to do sql db backup.But how can I backup db to split backup files? The reason I want to split the backup file is becasue single file size is too big and I want to write to dvd.
hello! can you take a look at my question? We use ARCServe to backup exchange server file (priv1.stm and priv1.edb) every night. When I select both of the files and start to back up using ARCServe. It showed me that Backup Operation Successful.
When I check the files, it didn’t backup both of the files. I don’t know why. Do you know how to backup these two files?
Hi,We are about to install MSSQL Server 2000, on a Windows XP HomeMachine. However, we have servers we could set routine backups of filesto be done to. What what be the best way of doing this?Is there functionality in SQL Server 2000, where we can say dump alldata definitions, accounts, and data to files on this drive at regularintervals?What other suggestions do you have apart from obviously the usual RAID,and Tape Drive stuff?ThanksDavid
I am going to move to a different host. Can I get back up files of my SQLServer database (from the host) and use those to set up on the new host? Andif so, is that what I should be asking for - backup files? Someone told methere should be 2 files.Thanks
Hi All,I searched the archives but I could not find any useful stuff for me.I can backup a database on SQLExpress like USE masterEXEC sp_addumpdevice 'disk', 'Store_1', 'c:Store_1.dat'BACKUP DATABASE Store TO Store_1Here is my problem: If I use logins,roles etc. in an application automatically a mdf file is created. Or I can create a new sql database. SQLExpress dynamically use the mdf file when connection string defined. This mdf file is not defined as a database on SQLExpress. Because SQLExpress has not a gui, I cannot see the registered database. How can I backup any sqlexpress mdf file without deattaching or attaching?Thanks
HiWhat is the easiest option for Exporting ALL of my SQL Server tables into a CSV file (either separate CSV files for each table or one big file with all the table columns and data) ???I just want to Backup my SQL Server database like we backup MySQL database using phpMyAdmin. Unfortunately, my SQL hosting company does not allow backups for free.Thanks for help
Hi, I am developing a tool that takes snapshot of a particular database. By snapshot I mean, attaching the .LDF & .MDF files. Would you please let me know how to access these files & take a backup of the same. And also how to restore them back. (using c# programming) Thanks, Archana A.A.
I need to know how big SQL Server 7 backup files are in comparison to the database size. For example if I have a database that is 300 Mb and I do a complete backup to disk with SQL Server 7 will the backup file be about 300 Mb?
I hv worked in 6.5. There we take backup through the command 'Dump Database'(e.g---> "Dump database master to masdump WITH INIT." ). As for as I know, in 7.0 we are taking backup using the command "Backup Database". Is it possible to use "Dump Database" command in 7.0.
i want to delete the backup files older than 15 days. how can i do this? Actually i backup the db and log using the TSQL, and the backup files are in d:ackup folder. I tried sqlmaint,xp_sqlmaint but its not running .
I have a large (200+ GB) database with many (100+) files. Please don't ask me why I did it this way; I inherited this database -- really, it wasn't my idea.
My predecessor also seemd to think that backups were unnecessary; there have been no backups of this database -- ever.
While we cast about for a good long term solution, I am trying various short-term options. One I want to explore is to back the database up in chunks -- ie, by backing up individual files. I created a test database with five files (there is only one filegroup on the production server). Here is the DDL:
-- ============================================= -- Create database on mulitple file groups -- ============================================= IF EXISTS (SELECT * FROM master..sysdatabases WHERE name = N'MultiFile') DROP DATABASE MultiFile GO
LOG ON ( NAME = MultiFile_Log, FILENAME = N'e:MSSQLDataMultiFile_Log.ldf', SIZE = 1MB, MAXSIZE = 10MB, FILEGROWTH = 10%) GO
I have tried the following backup script:
BACKUP DATABASE MultiFile FILE = 'MultiFile', FILE = 'MultiFile2' TO Backup01 WITH INIT
BACKUP DATABASE MultiFile FILE = 'MultiFile3', FILE = 'MultiFile4' TO Backup02 WITH INIT
BACKUP DATABASE MultiFile FILE = 'MultiFile5' TO Backup03 WITH INIT
And here is the restore script:
RESTORE DATABASE MultiFile2 FILE = 'MultiFile', FILE = 'MultiFile2', FILE = 'MultiFile3', FILE = 'MultiFile4', FILE = 'MultiFile5' FROM Backup01, Backup02, Backup03 WITH MOVE 'MultiFile' TO 'E:MSSQLDataaMultfile.mdf', MOVE 'MultiFile2' TO 'E:MSSQLDataaMultifile2.mdf', MOVE 'MultiFile2' TO 'E:MSSQLDataaMultifile3.mdf', MOVE 'MultiFile2' TO 'E:MSSQLDataaMultifile4.mdf', MOVE 'MultiFile2' TO 'E:MSSQLDataaMultifile5.mdf', MOVE 'MultiFile_log' TO 'E:MSSQLaMultFile_Log.ldf'
However, running the Restore script generates the following error:
Server: Msg 3259, Level 16, State 1, Line 1 The volume on device 'Backup02' is not part of a multiple family media set. BACKUP WITH FORMAT can be used to form a new media set. Server: Msg 3013, Level 16, State 1, Line 1 RESTORE DATABASE is terminating abnormally.
I'm not sure what to make of this. What do I need to alter in either the backup script or the restore script to make this work?
I am trying this because my objectives are to: 1. Limit the amount of work that the server is performing during any one given backup session. The idea that I have is to backup the database in chunks using a rolling 3-5 day window. 2. The database must be up and operational 7x24x365 (except for one 4 hour window each month) 3. This is not the long-term solution; but I need something to tide us over until we can purchase additional storage capacity.
I appreciate any thoughts and or guidance you can provide.
I have had trouble with maintenance plans not deleting expired backups, & this filling the hadrdisk. i have now done an agent job using tsql backup with init/skip, so it just overwrites. problem now is that it fails saying the backup device isnt available (cant delet the file from OS either) - so this was obviously the prob with the maintence plans too - sql/os doesnt seem to be releasing the file after it is completed and a server restart is needed to release it... anyone know how to sort this? thanks des
When a new scheduled job is created for a Differential backup, the file specified in the Destination folder is automatically created by SQL Server. After the first time the job runs, is there a way to configure SQL Server to give each Differential file a unique name, including the timestamp (i.e. similar to Full Backup jobs)? I noticed my only options are 'Append to File" and "Overwrite Existing File." If I choose to enable "Backup Set Expiration," the backup job will not run, because it wants to append/overwrite the filename specified.
Looking at the documentation, it would suggest that as well as data files, when a backup file's created it will also be zeroed out unless the service a/c's been given Perform Volume Maintenance.
We take our backups to dedicated backup servers, meaning backup performance should improve significantly if instant file initialization's given to the Service account logins for the source boxes if I'm right.
I have sent a mssql backup file in .bak format to my host admin and asked them restore it. but they told me there are 3 files with 3 different dates in that backup what does it mean? should I ask them to restore all of them or just the last one? Thanks very much in addvance (context: MS SQL 2005 express)
