I am new to SQL and might be missing something very easy. I have a situation where the space allocated to the transaction log of a database is extremly large (5 Gig). I can not manually reduce it. This gives me a "Error 21335: [SQL-DMO]The new DBfile size must be larger than its current size." This is a problem because the increase in size has taken all available space on the server.

Hello,
Somebody know how to reduce the space allocated for the transaction log space for my SQL_DB ?
3700 MB allocated but only 100 MB used and 3600 MB are free !
Transaction log properties :
Automatically grow file are filled
file growth by percent = 5%
maximum file size - restrict filegrowth = 3700 MB (we can't reduce it !)
Thank you for your precious help !

When I run dbcc memorystatus on my SQL 2005 Server under Memory Manager I get:
VM Reserved 33610144
VM Committed 1478012
Doesn't the VM Reserved seem really high? Is there a way to force SQL to release the VM Reserved memory?
hello everyone,
I have a question about the under what circumstances will a large database with mostly free space not shrink?
thanks
In an Intranet Application using Win NT, Apache, Tomcat and SQL Server, the memory space used by SQL Server is drastically increasing and finally the system crashes. Nearly 40 people are accessing the system. The hardware configuration is P2 processor with 393 MB RAM and 2GB Virtual Memory. SQL Server,Web server and Servlet Engine are running on same machine.
Within three hours, SQL Server occupies 200M memory and the system perfomance comes down and finally the system stopes the tomcat servlet engine.
Anybody have any idea on this? We have nearly 1500 JSP pages,200 Bean files and 300 tables in SQL Server.
I often in my job come across the following scenario:
Client rings up and says Run out of server space due to SQL 2000 Transaction log has consumed all the space or has consumed a very large portion of it.
what is the correct procedure in resolving this ASAP working with Full mode SQl 2000 Databases. as i have other
guys within my company that all do different things with good result and sometimes bad results.
The procedure i use is the following:
METHOD 1
1.backup both database and transaction log
2.Right click the database and select Detach, which from my understanding is a clean detach method which ensures that uncommited transactions are commited to the database.
3. Rename the old transaction log to .ldfOLD
4. REATTACH Database which creates a new transaction log.
METHOD 2
1. I dont use this method but im pretty sure its risky and if possible
can someone provide me with the reasons why:
1.Change database method from full to simple mode, shrink logs
and then change back to full mode.
basically what i am asking is what is the fastest way to sort out the above issue most effectively and with the abilty to Roleback succesfully.
PLEASE dont comment on why is the transaction log so big as i dont want to look into that now all i am sking is what is the most effective method to shrink the log down and save space.
Hi Folks,
It has come to my attention recently that my Transaction Log 200MB and a 1Gb Data Device has gotten much bigger than it used to be after
I deleted several thousand rows of data.
It used to be under 5% space used and now has settled at around 70 % space used. I have dumped the transaction log with no_log and done
backups immediately after on several ocassions and this has not solved the problem. I have also increased the log size from 150MB to 175MB
but this does not seem to have solved my problem.
Anyone got any ideas on how to decrease the % used log space in the Transaction Log ?
Is it bador unwise to have so much of the Transaction Log space used up ?
Thanks in advance,
Alan
I'm working with a database that has a relatively small amount of data. The size of the data file for this database is in the 100-110 MB range, which gives an idea of its size and how much data is in it. What is slightly troubling and baffling, is that the transaction file for this same database is significantly larger than the data file, at about 2.5 GB. What could be happening that is causing this transaction log to be larger than the actual database size?
Thx
Hello everyone,
I'm not sure if this is a problem but I've got a database which is about 1700mg in size (at least that's the allocated space on disk) and the log file is over 4600 mb. I've truncated the log file but it still keeps growing. None of our other databases are this large and there are a lot of transactions performed regularly but it looks odd to me that the log is this big when the data is half the size. How can I find out exactly how much space is being taken up by the data and is there anything I can do that will shrink the size of the log file? I am not really a dba so I'm not sure how crucial this is in the grand scheme of things.
Thanks
i have a few tables using Sql Server 2005 Express. currently they are holding roughly 30-40k records in them. i have my log files set at restricted growth to 90 megs. while im not close to reaching that, i would like my tables to be able to scale up to possibly millions of records. based on that, i figure the transaction log file will prolly need to have a higher threshold (unrestricted growth). for those with experience, for tables that have millions of records, what are the average size log files i could expect.
is it a bad idea to just shrink the log file every night during off peak hours so that regardless of the amount of records i have, ill always start the day with a minimal log file?
do large log files have any effect on SQL performance?
I have a huge table with ~30G data, and a column needs to be updated. In order to avoid a huge transaction, what I did was setting up a loop, update part of the records in each loop. The query is like following:
Declare @mo smalldatetime
Declare MOs cursor
for
Select [a month] from [a table]
Open MOs
Fetch Next from MOs into @mo
while @@FETCH_STATUS = 0
Begin
exec sp_UpdateColumn @mo
-- PRINT @mo
Fetch Next from MOs into @mo
end
close MOs
deallocate MOs
sp_UpdateColumn is the query that actually does the update, the code is like following:
Create Procedure sp_UpdateColumn @updMoDate smalldatetimeAS
[do some calculation here, store results in a temp table #Temp1]
Begin TranUpdate A set col =b.col from [big table] A, #Temp1 B where [some matching conditions]Commit GO
The BEGIN TRAN and COMMIT lines were meant to break up transaction, however, our database support people still tell me that a huge transaction has generated a GB sized log file that blocked the drive. Unless the transaction wasn't really splitted this should not happen. Can someone help me take a look at the code and tell me is there anything wrong? Thanks
Hello,
I am having a strange problem, never encountered before. I have a database that has been allocated 3000MB of Data space and 1200 of Log space. When i go an check the Properties of Database it give a count of 662.23 Data space available and 47.99MB of log space available. That`s weired. I tried truncating the log the Log space available is still the same and neither there is a change in the data space. It should`nt eat that much of data space according to my analysis.
Any insight
Please help ASAP

Is there a way to know how much space is free in each transaction log file of the same database?
Example:
A database with 3, 1GB files for transaction log: A, B and C created in this sequence.
From what I have read, since SQL Server 2005 writes to a single transaction log only, I guess if the transaction log is using 2.5GB than A and B are full and B is only half full. Is this correct?
Thanks.

Hi friends ,
I have a database with around 2 GB space for the data and 5.8 GB for the
transaction log .
Now the problem is i do not have any more space on the system and data files requires more space than 2 G.B to execute some stored procedures .
Is it possible to decrease some space of the transaction log , say from 5.8 GB to 2 GB and allocate it to the data files .
My data and log files are on different drives . I did not find anything related to this topic in the BOL .
Can somebody help me with this problem ? Anthing related to this issue will be of great help to me since i have no expertise in this field .
Thanks and Regards

The transaction log takes up a lot of space on my database, and even after I try truncating the log, doing a transaction log backup, and then shrinking it, I am not allowed to reduce the size of the transaction log to less than 250MB. Is there some reason why this space is required?
View 1 Replies View RelatedHi,
I started working in one company as a DBA where the Ex-DBA left the company long time back. So all the databases have huge transaction logs (50-80GB) in size. But the problem is-
1. HDD space on the m/c its only 45GB. When I ran TLog backup cmd on that m/c, the hdd space was started reducing around 1GB/min and in few minutes I saw hdd space left is only 15GB so I stopped cmd (It had completed only 37% of the backup).
Second time again I tried to take TLog backup on hdd placed on n/w path but again I saw it was eating local disk space very fast.
So my question is, Is it like when you take Tlog backup of size say 80GB it will use 80GB local hdd as a temporary storage?
2. For this I found 1 workaround- I took Full backup then I restored it on some other m/c, then shrun the log files to few MB's then I again took Full backup of this shrunk db and restored it on production.
Is this only solution to my problem(Very less space on production's local HDD)? If anyone knows better soln than this then plz suggest me.
Thanks in Advance.
Gurus,
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?,
All your suggestions are welcome.
TIA,
-Jay
I have a table that’s about 3 gigs, using this table and a few others I’m making another table. The problem is when making the new table my transaction log inflates so much that I’m running out of disk space. What I can I do to prevent this or to keep the transaction log size under control?
View 4 Replies View Relatedtoday I've put in production a big database accessed by 200 concurrent users, this database has READ_COMMITTED_SNAPHOT set to ON.I know that RCSI set to ON is very aggressive on tempDB so I'm monitoring it.I've noticed that the Transaction log space usage (%) on TempDB is slowly but ever increasing, I mean in the last 24 hours I've started from a 99% space free, now we are 37% space free...is it normal? TempDB log is 35GB in size.
View 6 Replies View RelatedI am having a problem backing up my database and TLog files due to alack of local diskspace. The db file is about 30GB and the TLog isabout 20GB each on a different hard disk. Each disk doesn't haveenough available space to accomadate a backup. I also can't shrink thefiles because part of that procedure would require a backup.Question: Can I use a redirected drive for the backup media? Is therea way to trick SQL into allowing this? If the answer is no, doesanyone have a suggestion as to want I should do? I am in the processof requesting more disk space,but that could take a while.Thanks,
View 3 Replies View RelatedIn my environment, there is maintenance plan configured on one of the server and while running DBCC checkdb on a database of size around 200GB, log file usage of tempdb is increasing and causing the maintenance job to fail.
What can I do to make the maintenance job run successfully, size of the tempdb database is only 50GB and recovery model is set to simple. It cannot be increased as the mount point on which it is residing is 50GB.
Currently we has a database of size about 300G. Because our backup system failed some time past we were left with a transaction log file which grew to about 160G. However our backups are working again and everything is working fine. My understanding is that now the transaction log file is practically empty but the capacity remains at 160G.
When you delete records the deleted transactions are going to get logged to the transaction file. My understanding is when a backup is done these transactions get discarded out of the transaction file.
could I make use of this relatively large transaction file and start deleting transactions without out actually adding to the transaction file size.
The plan is to delete records from logging tables that are not referenced to by any other table without this increasing the transaction log file.For example over a period of a few weeks we can delete a chunk of records from a table. Then after it has completed a backup we can delete another chunk of records out of this table until we have got the table down to the records that we now need.Will this work?

I am generating a Report from Sql Data Source in Sql Server 2005 and viewing the Report in Report viewer control of Visual Studio 2005.
The data in the Data Source contains string with multiple spaces (for example €œ Test String €œ) but when they get rendered in Report viewer control, multiple spaces gets converted to single space €? Test String €œ.
I tried following solutions
1) Replacing spaces with €œ €?
2) Inserting <pre> tag before the string and </pre> tag after the string (Also tried <Pre> instead of <pre>)
But in all the cases result is same. The Report Viewer control is showing €œ €? instead of space and €œ<Pre>€? tag instead of preserving spaces.
Please provide me a solution so that spaces can be preserved in Report Viewer.

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?
This is driving me bananas. Can't find any info on this anywhere....SQL 2000 seems to replace double space with a single space when I seta varchar field to " " (2spaces), it only stores " " (1space). Whyon earth would microsoft do this? If I save 2 spaces - I WANT TO SEE2 SPACES!!!!Can anyone help? Is this a database setting? Is this due to usingvarchar?Any help appreciated.Colin Hale

I have a design a SSIS Package for ETL Process. In my package i have to read the data from the tables and then insert into the another table of same structure.
for reading the data i have write the Dynamic TSQL based on some condition and based on that it is using 25 different function to populate the data into different 25 column. Tsql returning correct data and is working fine in Enterprise manager. But in my SSIS package it show me time out ERROR.
I have increase and decrease the time to catch the error but it is still there i have tried to set 0 for commandout Properties.
if i'm using the 0 for commandtime out then i'm getting the Distributed transaction completed. Either enlist this session in a new transaction or the NULL transaction.
