I have an interesting problem here. I am running SQL Server 2005 and have a large database. After running some scalability tests over the weekend my MDF file size went up to 25GB and LDF file size went up to 27GB filling up all available disk space. I didn't do any backups, so it is understandable why the LDF file size is so large.
Now I am trying to shrink the LDF file. However, DBCC LOGINFO indicated that all LVFs within the LDF are active (Status = 2). I detached the database to make sure no active connections exist and ran CHECKPOINT, but still DBCC LOGINFO lists all LVFs with status 2. Since all LVFs are up to date I can't shrink my LDF file.
Why are all LVFs still active after detach/attach and checkpoint?
How can I shrink the LDF file?
I have a 13 Gig Log File with only 121 Mgs of space used. I have run the DBCCSHRINKFILE command and it has shrunk it by about 100 Mgs. Why can't I get it to shrink to a reasonable size.
Hi, is there any other way to shrink the log file other than truncating every time it gets bigger... I have a 800MGs database and the log is getting as big as 11Gigs... any suggestions other than truncating it? Is there a way to set it off?
DECLARE @i int SELECT @i = 0 WHILE (@i < 300) begin INSERT t2 values ('a') SELECT @i = @i +1 END DROP TABLE t2
BACKUP LOG PBDSSTEST TO PBDSSTESTLOGBACKUP
Before I ran this the used portion of the log was 1795.12 MB, the free was 1570.50 MB for a total of 3365.62 MB.
After completing this the used portion was 25.62 MB, the free space was 3263.50 for a total of 3289.12 MB. It only srhunk about 26 MB. Why won't it shrink it anymore. There was plenty of data in the used at the time of the shrinkfile command so I would have thought it would have shrunk it a lot more. Please help. I don't understand why it won't shrink it anymore than it did.
I have a problem with shrinking a log file on SQL 2000. The log file has grown to 25gb (the db is 30gb) . The DB was in simple recover mode but I have changed it to full so that the log file can be backed up. I have run the dbcc shrinkfile on the log file several times (plus log file backups) and it has increased the logfile size. Each time I have run shrinkfile I get €˜Cannot shrink log file 2 (db_Log) because all logical log files are in use€™ message. I have used the dbcc loginfo command and this shows that all the virtual log files are in use. The db also publishes 4 snapshot replications. Any suggestion for how I can easily shrink the log file?
I have a database that was loaded with large amounts of data before today. I backup up the db and trans log. presently the DB file is 328 while the trans log show 428 meg with only 28 meg being used. If I try to shrink either the database or the log files, the log file wil not shrink.. It tells me to set it to a minimum of 28 meg but still not shirnk. I realize this was a problem in 7, any quick fixes, in a hurry. Running SQL 2000 SP1
I'd like to create a stored procedure to automatically shrink the transaction log file on a certain database monthly. As I am not the DB admin (it's a web-based db on a remote server), I'd like to put together a script to create the procedure so I can just send it to the DB admin to run. It seems like it should be pretty easy, but I'm still pretty new to SQL server. Is anyone able to give me some pointers?
I have a relatively high usage 2005 database whose transaction log grows every day.
Untill now I have been manually shrinking the log files .. but I would like to automate this process.
In the maintenance schedule that runs every night
1 Do a full backup to disk 2. Do a transaction log backup to disk 3. run the following TSQL
USE [MyDB]; GO ALTER DATABASE MyDB SET RECOVERY SIMPLE; GO DBCC SHRINKFILE (MyDB_log, 3000) GO ALTER DATABASE MyDB SET RECOVERY FULL; GO
4. Backup disk files to tape.
however it doesn't work !! the TLOG file does not shrink, even though its the same as the manual job that I run?
There is nothing in the SQL logs .. but in the event log I get
Event Type: Error Event Source: SQLISPackage Event Category: None Event ID: 12291 Date: 13/12/2007 Time: 00:50:10 User: NT AUTHORITYSYSTEM Computer: ALGSQL1 Description: Package "MyDB_FULL_BACKUP" failed. For more information, see Help and Support Center
please advice me what does .ldf file consist of and can i shrink the .ldf , is it adviceble to shrink after the backup and how frequently it can be done on a production db
please advice me ,can i shrink the .mdf , it is adviceble to shrink after the backup and how frequently it can be done on a production db
(SQL 2005) I have a few databases that are currently hovering at around 150GB. (The following only concerns the .mdf) Of this total size, only about 90GB is real data. The other 60-70 is data from unecessary audit tables. Recently, we've been having some space issues on a 1.7TB server. We've decided that deleting these audit tables and reclaiming the 60-70GB per database is the route we're going to take.
What we did: DELETE <table> (per audit table). Now, it shows that the database size is ~90GB and there is the 60-70GB of unallocated space.
Then, we ran a DBCC SHRINKDATABASE (db_name) overnight. Checked space the next morning and only about 10GB had been reclaimed. We've tried a number of other alternatives of which, none have been successful.
(DBCC SHRINKFILE(file, space), drop and recreate tables, etc.)
Can anyone think of any reason why these commands would not be working? If I can provide any additional information, please let me know.
Is there a fairly quick and dirty way to shrink the file size allowedfor a DB on SQL server after the DB is in use?Our old DBA allowed 3 gb for log files and we don't need nearly thatmuch. However, the space is still being used and reserved. Can Ishrink that "maximum" and clear up the space?I don't want to just copy all the tables and primary keys and open anew one with the new data, though that is plan A right now.I cant just change sysfiles, it yells at me.
I've been searching and reading for best practices on how to maintain a reasonable log file size while engaging in Log Shipping. I have found plenty of information on these subjects on their own, but not on how best to shrink your log size without breaking your log shipping integrity.
On a SQL Server 7.0 database I support, I've been unsuccessful trying to shrink a data file using dbcc shrinkfile (datafile_logical_name, 0). This worked fine for shrinking the log, but of the 4 datafiles that were created 2 shrank successfully and 2 remain unchanged. Unless the information on the General Tab on Enterprise Manager is incorrect, of the 15000MB allocated for one of the files, only 700 MB are used.
I have inherited a SQL 2000 database ( (I am new to SQL DBA) and I found this when I was checking the db properites . The transaction log has grown bigger than the actual data file, I thought transaction log backups would truncate the inactive portion of the log file and shrink the transaction log, but it was not the case it seems, may be it was truncating the inactive portion of the log, but not shrinking it. This site does not have a job for truncating the data/log files periodically. What is the best method to deal this situation, how can I shrink the Transaction log quickly?,
My intention is to include a sql job to schedule for shrinking log files to half of its original log file size (if half of their original size is greater than 5MB)
The code is below. But while executing the code it is keeps on running indefinitely. can somebody throw some light what cause it to go into an indefinite loop.
Thanks Babu
code: ==== DECLARE db_file_name CURSOR FOR SELECT name , ceiling(size/128.0) * 0.5 FROM master..sysaltfiles Where rtrim(lower(filename)) like '%.ldf'

OPEN db_file_name FETCH NEXT FROM db_file_name INTO @f_name,@new_f_size WHILE @@FETCH_STATUS = 0 BEGIN If ( @new_f_size > 5) BEGIN DBCC SHRINKFILE ( @f_name, @new_f_size ) FETCH NEXT FROM db_file_name INTO @f_name,@new_f_size END END CLOSE db_file_name deallocate db_file_name
We are using Sql server 2012. One of our production database has hight no of vlfs. We are planning to shrink the logfile to reduce the no of VLFs but the database is configured for logshipping.
What is the effect of logshipping when you shrink the logfile?
I have a large (420GB) database that has never had data archived off before. I taken a backup to a test server and run a script supplied by the product vendor which has removed a large ammount of old data no longer required.
I have checked within enterprise manager that this data has now gone, however the actual file itself has not shrunk in size. Is there a further step I need to take to get back the space.
Hi! I have a database where I add some new Filegroups and moved some Gb's of tables and indexes to new file groups. Now I would like to shrink the source of these tables/indexes: the mdf file. This means there should be much empty space now in the mdf file.
I tried to use dbcc shrinkfile, but it run for more than one day. Are there some good strategies about shrinking the mdf file? I had to restart the instanse because got problem using the db while dbcc runned...
Hi.. I was doing a good maintenance on my DB and my trans log LDF keep growing until 30GB but my DB data file MDF is only 2GB. I found the two following method to reduce my log size.
Method 1: I used veritas to backup log file with truncate Method 2: I used the shrink database option in Enterprises manager to shrink it (file chosen=log , use default option)
After doing that, I found my LDF log file is still about the same size=27GB but when I see clearly, from the shrink database windows, the log spaced used reduced to only 100MB, the allocation log space is still 27GB. Why? How to make the LDF smaller to be the around the same size as the space used 100MB?
Hi all:I restored one backup database (7.9 GB mdf) on two diffrent servers. Ishrunk them by clicking "Move pages to beginning of file beforeshrinking".After shrinking, one mdf file is 6.7 GB, and the other is 4.2GB. Ishunk again and again:1. the 6.7GB become 5.9GB, 5.2GB, 4.7GB and 4.2Gb (four times)2. the 4.2Gb become 4.0GB (just one more time)It is wired, I am wondering the mdf will be smaller and smaller if Icontinue to shrink them? What is the reason?ThanksWJ
The problem is solved but still I would like to know what is going on behind the scenes. I was always thinking that the native client was involved and not oledb.
Using the Export/Import wizard you still end up going via SQL Server Agent that's where the Credential/Proxy items show up.
I'm just beginning to use DTS. I have a test table which has only two column, char (10) and decimal (5,0). I want to do a simple transformation by adding the second column by 100 with the following statement, but I receive a type mismatch error!
Function Main() DTSDestination("a")=DTSSource("a") DTSDestination("b")=DTSSource("b").Value + 100 Main = DTSTransformStat_OK End Function
or
Function Main() dim x DTSDestination("a")=DTSSource("a") x = DTSSource("b").Value + 100 DTSDestination("b").Value = x Main = DTSTransformStat_OK End Function
Hello friends I need a very ergent help!!!!!!!!!!!!! Problem: my sql server on production had everything grayed out, when I want to administer this server as a SA. eg: I can't add users, I can't backup and so on. but the database is still running and users are accessing it. This SQL database is accessed by an application(it can also create users on the backend). I don't know how it happend ( i cant even get to errorlog). I beleive somehow sa user rights were taken away from him. Can anyone tell me how to restore sa with all rights.
Please help me on this matter, because I have to do lots of important tasks on this server.
Test1 that lists all the training courses that i can count to find out the total as below.
select count (distinct Training_Course) as total from Test1
Then Test2 lists all our customers and courses they have attended. I count the courses attended and then group by their ID.
select Cust_id, count (Attended) as TotalAttend from Test2 Group by Cust_id
What i am now trying to do, without any luck, is find out which Customers have attended all training sessions by comparing the two queries and only bringing back the cust_id where it matches the total count from the Test1 query.
Make any sense? Any help/suggestions gratefully recieved.
