Reduce Databse Size
Jul 20, 2005
Hi, my database size has grown out of control and I need help with the
following issues. (I am very new to databases)
I am storing financial tick data in one of the tables and after two months
the database has grown to 30GB. I do not need a permanent record of this
tick data after it has been processed and tried to remove all rows from this
table (delete from Tickdata), however sql does not take kindly to removing
millions of rows and the operation seams to time out. The only solution I
could come up with was to delete the table.
Secondly, after managing to clear out these tables I have noticed that the
database size is still 30GB, despite 29GB being available. Is there any way
to reduce the size of the database from 30GB. I tried the shrink database
option but it does not do anything. Any ideas?
Thanks.

I'm new to SQL Server Maintainance. I need some disk space now. In my database, I have some table that has 7 year old data and I can get rid of that without any conequences. Could you please tell me the best course of action ?? I was thinking about:
1. Dropping those tables.
2. Recreating them again
3. Running ShrinkDB on entire DB.
However, this solution does not sound right or elegant to me. Could you please help me with that ? Thanks

I am using SQL 7, SP1 / NT 4. The .LDF file has grown to 1.1GIG; I ran a DBCC SQLPerf(LogSpace), the used portion of the log is 2%. When I run a DBCC Shrinkdatabase and DBCC Shrinkfile, the log file does not reduce in size. How do I get the virtual log files that are not active released back to the system? Is there a way to tell if all the virtual log files are active, therefore, not reducing the size of the file? Any help is greatly appreciated.......

hi, i'm a newbie in SQL Server and have recently setup a test SQL 7 server. I used all the defaults at the beginning, and now the MDB file is about 500MB and the LDF file is of similar size.
i'm still trying to figure out how to reduce the size of the transaction log file. Currently I only have full backup of the database once a week, and there is no backup for transaction log.
as of this moment, the transaction log is of not much use to me, but I really want to get it reduced as i'm running out of disk space.
and i'd also greatly appreciate if someone could suggest a good DBA practice on the proper setup/handling of transaction logs (how to balance the disk-space usage AND be able to use the transacton logs for proper roll-over during a recovery process).
i'd soon be setting up a SQL 7 server where about 10 active users are expected at any one time. I've read that the transaction log file should be about 40% to 50% of the estimated size of the database file, and should be allowed "auto-grow". So what happens if the more space is required by the transaction logs? Does a full-backup purge the transaction logs (like the way they do in Exchange Server)?
Thanks!

We have a database which was created with an initial file size of 10 gig. Currently it is only using 2 gigs.
We have developers that want to have a copy of the database on their desktops, but do not have 10 gigs free space.
What is the best way to get them a copy of the database while reducing the footprint?

The size of my transaction log file is out of control. I've backed up the database and the transaction log went from 120 GB to 120 MB. Now, I can't reduce the size of the transaction log file. It's still at 120 GB (w/ almost all of that being held as Free Space). I get errors when I try to manually reduce the file size. Any tips?

We are using SQL Server 2000 Standard ed, sp4 on Server 2000 Advanced.We have one table that is three times as large as the rest of the database.Most of the data is static after approximately 3-6 months, but we arerequired to keep it for 8 years. I would like to archive this table (A), butthere are complications.1. the only way to access the data is through the application (they areimages produced by the application-built on Power-Builder)2. there are multiple tables refrencing this table and vise-versa3. we restore the entire db to two other servers for testing and trainingregularly4. there might be more complications that have not been thought ofCurrently, our only plan is to setup a seperate server with a copy of this dbon it and the application. Leave only the tables necessary to access the data,and if this 'archive' works, remove from production the data from the table Aand all references to the table A from rows on the other tables.I mentioned #3 because someone mentioned a third party tool that may be ableto pull the data from the table, archive it elsewhere, and at the same time,place a 'pointer' in the table to the new storage location. The tool theymentioned only works on Oracle and we have not explored beyond that yet.I am ready to explore ideas and suggestions; I am still new to the DBA world,I am out of ideas.Thank you!--Message posted via SQLMonster.comhttp://www.sqlmonster.com/Uwe/Forum...eneral/200607/1

Okay, I know the maximum size limit on a database in SQL 2005 Express is 4GB, but what happens when you exceed that limit? I can't seem to find much info on that topic. What kind of error return would you get from a stored procedure attempting to do an insert that will exceed the 4GB limitation? Also what factors go into that maximum size, factors that might not be completely obvious of course?

I have a Reporting Services report available in a Windows Sharepoint Services webpart. The report is too large to display in the webpart window requiring the user to use the scroll bars. Is there any way to reduce the size of the report so that fits completely within the webpart without using scroll bars?
Thank you.

Basically, what I'm doing is storing answers to questions in a survey. I have two ways I can organize the table:
1. Just having a table with lots of columns - one for each question
2. A table with only about maybe 3 columns:
SurveyID
QuestionID
QuestionAnswer
In this second case, the the primary key would be both SurveyID and QuestionID combined, of course.
I don't fully know the pros and cons of the two approaches, and both look like they would work. Right now, I'm using option 1, but I keep wondering if option 2 might be better. Whenever I change the questions, I currently have to drop and recreate the table (altering it is too much effort), and I know option 2 would be a way of avoiding that. By the way, the questions themselves are stored in an xml file, if it means anything. Anyhow, once the survey is being used, there shouldn't be any further changing of questions. And there's also just too much I don't know about (how is performance affected, for example?).
Any ideas which is better and why?

I have a search function, which searches across many tables.
It's a pretty heavy SPROC, I'm wondering in general, what are the best way to reduce deadlocks ? Its used a fair bit, and altho I haven't noticed problems with it myself, there are definately a decent amount of deadlocks showing up in the logfiles.
I've always assumed this is something really difficult, and avoided it like the plague.
Any tips are much appreciated !
thanks,
