Transaction Log Growth Question
Nov 23, 2004
Hi DBA's,
I have the tran log backups running every 30 mins. When I re-build indexes on my database with the tran log back ups runniing every 30 mins, I get tran log backups whose size is greater than the actual log file (.LDF). I find this really strange as to how can the backup be greater than the log file itself.
I have unrestricted growth on the tran log file ( By 10%). Auto Shrink is disabled.
Have any of you experienced this problem. Kindly share your comments.
Thanks,
V

I received alerts from a couple of the production servers last night stating that the log file is running out of space. So, I took some log backups and shrunk those files. However, I would like to find out what made the log grow like that. After all, I have t-log backups scheduled every 30 minutes.Is there a way I can find out the reason behind the log growth?

During my maintenance plans every night, my transaction log for a 17GB database grows to about 9.5GB. I am running transaction log backups every 2 hours, and my transaction log stays around 300MB during the day. However, every night when the optimization job runs, this explosive growth occurs. I have the optimizations set to Reorganize data and index pages, changing free space to 10%, and remove unused space from database files to 10%, shrinking when they grow beyond 50MB. This database handles cash register operations which are not active during the maintenance plan.

Hi All
I'm getting this when executing the code below. Going from W2K/SQL2k SP4 to XP/SQL2k SP4 over a dial-up link.
If I take away the begin tran and commit it works, but of course, if one statement fails I want a rollback. I'm executing this from a Delphi app, but I get the same from Qry Analyser.
I've tried both with and without the Set XACT . . ., and also tried with Set Implicit_Transactions off.
set XACT_ABORT ON
Begin distributed Tran
update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=****').TRANSFERSTN.TSADMIN.TRANSACTIONMAIN
set REPFLAG = 0 where REPFLAG = 1
update TSADMIN.TRANSACTIONMAIN
set REPFLAG = 0 where REPFLAG = 1 and DONE = 1
update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=****').TRANSFERSTN.TSADMIN.WBENTRY
set REPFLAG = 0 where REPFLAG = 1
update TSADMIN.WBENTRY
set REPFLAG = 0 where REPFLAG = 1
update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=****').TRANSFERSTN.TSADMIN.FIXED
set REPFLAG = 0 where REPFLAG = 1
update TSADMIN.FIXED
set REPFLAG = 0 where REPFLAG = 1
update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=****').TRANSFERSTN.TSADMIN.ALTCHARGE
set REPFLAG = 0 where REPFLAG = 1
update TSADMIN.ALTCHARGE
set REPFLAG = 0 where REPFLAG = 1
update OPENDATASOURCE('SQLOLEDB','Data Source=10.10.10.171;User ID=*****;Password=****').TRANSFERSTN.TSADMIN.TSAUDIT
set REPFLAG = 0 where REPFLAG = 1
update TSADMIN.TSAUDIT
set REPFLAG = 0 where REPFLAG = 1
COMMIT TRAN
It's got me stumped, so any ideas gratefully received.Thx

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.
and
Failed to open a fastload rowset for "[dbo].[P@@#$%$%%%]". Check that the object exists in the database.
Please help me it's very urgent.

Does this seem right? We have our transaction logs set to "Truncate Log on Checkpoint" and they still grow over 1GB. Is it possible that one transaction (to a checkpoint) generates this much logged information? Will transaction log backups every 5-10 minutes help me out better or is this just a poorly written application?
Thanks!

I am having a problem with the growth of the tempdb on my SQL 7.0 box. I have over 300+ stored procedures that are running (many with group by and order by in them). This is causing the size of my tempdb to grow to over 30gigs in size. If i reset the services of the DB it shrinks back down to the managable 6 gigs that i expect. Is there a way to have the services restart automatically on a nightly basis or is there a way to have the tempdb deallocate resources once they are used without restarting services?
I apreciate any help you can provide,
Nathan

Hi everyone,
I'm a beginner in SQL Server databases, my problem is this:
i'm making a database witch the frontend is an access project, the database has several stored procedures views and user functions (the normal..), but a few data, (only the experimental), last night i've noticed that the file grow from 22 MB to 89 MB, the objects are the same and also the data, the only diference was that i forgot to put in an event procedure code, the ADO method, "MoveNext", to update various records, and the loop was infinit.
Is it possible that SQL statments generated by ADO make the file grow so rapidly!?
If so how can i shrink it, because i've tried and and the results was 4%.
Can you help me!?
Thanks

We use SQL 2000 and our database is configured to grow automatically by10%. Currently 96% of our database is used. At what point will thedatabase expand - what is the trigger point?

I've got a question about the automatic database growth feature of V7. Here's an example:
I have a 1gb db that can grow to max size of 2gb.
I set the auto grow option to 75%
The first time the db grows it will grab 75% of the free space (1gb)
What happens if the database needs to grow again?
Will the db grow using the remaining free space (25%) or
has the database reached its max size because it can't grow any further?
Thanks

Hello,
I started to write a stored procedure to insert into a temp table from sp_spaceused but couldn't get the format right. I did a search in the swynk archive and saw that some people have solved this but I couldn't see any example code. Does anyone have scripts they've written to gather db size info using sp_spaceused or some other mechanism?
Thanks in advance,
Dan

:eek: I am somewhat confused -- I have a database in production that I restored to a QA environment; upon restore, the size has grown by 200MB.
Both production and QA are running SQL2000 -- the only difference is that QA has the latest security hotfixes installed -- version 8.0.0.665 from KB article at the following link:

Restore/Log Growth Question:
We have an SQL2K SP3 Decision Support Server which will be receiving a nightly data dump from the offsite production system. We’ve decided on a backup/restore process to move the data. We’re currently testing the process and have come across a problem. The test backup file is only 500MB, the real DB will be approx. 20GB, and when it is restore the DB is fine but the log file has ballooned to 8 GB.
When the DB is restored the properties of the production DB are forced over our settings. These include no truncation of log on checkpoint and a full recovery model (the destination DB will have simple recovery). We’ve been through the books online and search online forums, but have not found information on this particular problem. We can, of course, shrink the log file after restoring but are concerned about the amount of dead space needed when the real DB is delivered.
Any help would be greatly appreciated.

We have a SQL 2000 database here. As of 3 days ago, it was about 75 megs ( 73 Data / 2 log ). As of today, it is 73 Meg Data / 15 GIG log. The log file went from 2 MEG to 15 GIG in a matter of days, yet the data file size has not changed. also, there are NO users to this database - it's new and has not been placed into production yet. I currently don't have any idea as to what happened - I'm looking into Lumigent's log explorer software now. Does anyone have an explanation as to why the log file would have increased 6000X in size, yet the data is not any larger ?
Thanks,
JK

All:
I've got a serious problem happening now with the transaction log on one of my databases. The log keeps growing at an alarming rate - avg. 1GB/hr on a ~550MB database; there's nowhere near that much insert/update activity in the database. This is causing space problems with the (hourly) log backups.
The database serves an internal web site; both the web server and the SQL server have been bounced, but this keeps happening.
Profiler shows many, many TransactionLog events in Profiler - orders of magnitude greater than other events. User activity is no greater than it ever is. DBCC OPENTRAN consistently returns no open transactions. I've created a job to checkpoint and truncate the log right before the log backups, but that's obviously only a stopgap for the backup space problem & not a solution.
Do you have any suggestions as to where to go from here? I'm at a loss, and this can't stay as it is. Thanks for ANY input...

Hi,
While I am importing few data to my SQL Server (2000) database, the free space is gettig increased in GBs. The database's File Growth is 1 MB (same for both Data Files and Transaction Files). The same database I restored on another PC and did the same process, it is working fine as there is no enormous growth in Free Space.
Any idea why this is

Hello Everyone,
I appear to be doing something wrong. When I
set my Table for Unrestricted File Growth and
save it, When I go back and look at the settings
it is set back to restricted file growth.
It seems to me if you set any settings and apply
and/or save it. Should it not keep that setting.
Any advice would be great.
Thanks

SQL Server 2000 SP4. I built a large DTS package that grabs a numberof tables from an Oracle DB, does some scrubbing and date verificationand loads to a SQL Server DB. Most of the tables are full refresh anda few are incremental.Main DW: DwSQLStaging Area: DwLoadAreaSQLThe DW is about 60 Gigs. The Staging Area is about 80 Gigs. This isall good.However, the log file for the staging area is 50 Gigs and I'm tryingto find ways to not require such a large log file. I tried adding afew "BACKUP LOG DwLoadAreaSQL WITH TRUNCATE_ONLY" statements in theDTS package but figured out that because it's 1 DTS package it's all 1transaction. I've thought about breaking it up into multiple DTSpackages and truncating the log between running them but was hoping toavoid this. To be clear, I know how to shrink DB's and LogFiles...that's not the issue.Any Ideas? Thanks.

I want to be able to display the percent of growth for databases on the server. My query has the file sizes and names and the dates, its done monthly . How do i create a field with the growth % from one month to the next, or from one date entry , to the next. so it appears like this
2006 2007 2008
23000 % growth 3400 %growth 20000
keep in mind, this is how it is displayed in reporting services with a matrix(crosstab)
Here's my query
Code Snippet
SELECT RC_STAT.dbo.Tbl_Database_Statistics.AutoId, RC_STAT.dbo.Tbl_Database_Statistics.Server_Description,
RC_STAT.dbo.Tbl_Database_Statistics.Database_Size_Datetime, RC_STAT.dbo.Tbl_Database_Statistics.Database_Description,

I'm trying to insert a fact table using SSIS which has a primary key. This is a one time load of about 150m rows and after this I'll be doing incremental only. It takes more than 8 hrs and finally the ETL fails because of not enough disk space.
After that 8hrs,When I right click the property of the table and see the row count, I can see all 150m. but it seems like it takes forever to commit the transaction. But it keeps on adding to the Log and when it reaches just few hundred MB's left on disk space the row count just rolls back which takes another few hrs to come back to 0 and it fails....
I've changed the database recovery model to simple from full and I've set up the OLEDB destination- Rows per batch, and Maximum Insert Commit size to both 100000. Should I need to just leave it to 0? Or adding space to the log can solve the problem? ( I have almost 95 GB free before the load). I'm just having a hard time to understand why its taking forever to commit the transaction.
Can anyone shed some light?
Thanks-
Rok
