Hi,
can some one throw some light on how the DBAs calucaulate the space allocations?
For example I have 30000 records which has 30 columns each defined as varchar(100) and if the db is full and wants to increase the space. Then how much extrac space should be allocated??
Hi,
I need to create a 5GB database with 4GB for data and 1GB for log in v7.0. I know that in v6.5 I would have created five 1GB devices - to go easy on the backups.
Could someone please advise on how I should distibute allocation of space.
Should I allocate 1GB to the primary files and 1GB each to 3 secondary files?
Should I just allocate 4GB to primary?
I would really really appreciate any reponse? If there are articles I would appreciate links.
Thanks

I have a small data warehouse which periodically has old data deleted.
However after a delete the free space within the database is not released. If I copy the tables, drop them, recreate, and copy back, the space is there.
Any ideas what is causing this anyone ?
Thanks
Hello ,
I wanted to know on what basis the disk space allocation for the databases is planned . Suppose if we plan 60 GB for data files ( mdf )for a given database then what should be the space allocation for the log files ( ldf ) and the tempdb ( both mdf and ldf files ).
Is there any thumb rule or any defined ratio for the same ?
Thanks
Hey all, first time poster here.
Cheers!
Enterprise Edition SQL2k sp3a on Win2k3 Enterprise Edition server.
Using BCP to load ~4 million records.
Largest record width is ~350 bytes.
When finished i have over 6 million pages reserved and only about 800 thousand actually used.
Which puts me 'round about 3 rows per page and WAY too much empty space.
YIKES!
Any thoughts as to why this is happening?
Or insight into how BCP handles page allocations that may be different than the typical extent based page allocations for table data?
Thanks!
I was trying to find out how much space is available in a 2000 db for allocation to tables and indexes. I am trying to find the amount of space that has to be used-up before another allocation is automatically made to the database. I looked at sp_spaceused but BOL is rather sketchy at defining what the numbers it returns really mean. Is the "unallocated space" the value I am looking for?
Thanks,

Hi
I am using DTS to transfer tables from Oracle 9i to SQL Server 2000 sitting in a shared environment and managed to migrate
a lot of tables without glitch..
When I was migration a table <XYZ> from Oracle to SQL Server..The table was created in the SQL Server whilst the DTS threw an error that read when it was copying data and 0 rows were copied with the error message being
"Cannot create a row of size 8387 which is greater than the allowed maximum of 8060"
Incidentally the have a table in the Oracle DB that has 152 Rows of Data with 94 Columns..
Does any change needs do be done on the Admin side of the SQL Server to resolve this problem and faciliate effective transfer of data from the DB's?
Thanks in Advance

I have to force a space allocation to a DB file in order to stop a Diagnostic Manager alert which states that the database is over 80% full. Now, I don't think this alert is rational, nor do I think it is useful in any way but that's the way it goes. My only option is to allocate more space to the DB so that the space used will fall below 80% so the alert will stop being issued.
So, can you tell me how to force a space allocation on an existing db file?
Thanks,
Michael

I have a quick question maybe someone can answer me:
Suppose I have a database with data and log on same device, by default,
3 segments are created: system,default and logsegment.
Is the allocation , or any limit, among these segments(i.e. for system table, other table and indexes , log) done by the system ? or will the space required be allocated when they are needed ?
(i.e. I can have a situation of 10% database space used for data, 90% used for logging and I can also have 90% used for data, 10% used for log ?)
Is there any control us we can make ?
Of course, for recovery and performance reason, it is always recommended to have data and log on 2 diff. device.
I've faced with this problem in my DB:
There are some tables that suffer inserts and deletes daily. These tables have 3 nonclustered indexes including the pk.
I perceived that the space used for these tables are growing day after day even ocurring daily deletes.
These inserts and deletes follow the keys of the pk in ascent order.
I ran DBCC SHOWCONTIG on the tables and got results like this:
- Avg. Bytes Free per Page.....................: 7996.3
When I transform the pk to clustered this problem doesn't happen.
You realized the consequence of this: the users complains because the DB is without space, but it's not true!
Anybody could help me to understand why the extents are not being deallocated?
Thank's for help!

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 was wondering, is there a way to allocate processors to SQL2000. I have a server that has 4 processors, I would like to leave one just for the operating system and have SQL2000 use the other 3. Is this possible and do you think it would be recomended to do this? Or should i just leave the 4 processors for everything?
thanks in advance

I have windows 2003 with ms sql 2000. The machine has 3.6 gigs of ram and only runs ms sql, nothing else.
Whenever the first query is made sql will allocate as much as 1.5 gigs of ram which is just killing the system. This system reboots nightly so this first query happens every morning.
We have tried setting the min and max memory of sql, as well as the reserver memory setting to see if it will preallocate all that memory but we've had no luck.
Is there a way to make SQL allocate all that memory ahead of time? maybe make it cache some tables or something?
I know very little about MS SQL so please be very descriptive about possible solutions or troubleshooting steps.
Thanks,

Any comments, please. I have a new server 5x160GB drives. It needs to run IIS for a web app and SQL Server 2005. One user database. I was thinking of dividing space as follows and wanted to get some thoughts from others.
2 drives = RAID 1 set, 160GB space, OS, IIS, SQL exe, tempDB, user database log file
3 drives = RAID 5 set, 320GB space, SQL data files, user database files
Thanks for looking...
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 !

Here is what I am trying to do...
I want to goup "members" togethers in a "group."
A table for members and a table for groups.
each containing coluns...
but inside Groups I would like a column that contains ID numbers for the members that be long to that group.
Being that members can belong to multiple groups - I can not use a GroupID in Members - if so I also need a way of it modular.
Obvisiously I am not a very good DB programmer - but I want the least amount of empty/unused space in my tables.
Hope this makes sense
On two different unrelated servers this week, I got these errors from a DBCC CHECKDB(tempdb):
Msg 8905, Level 16, State 1, Server NTSONYX, Procedure P_DATABASE_BACKUPS, Line 121
[Microsoft][ODBC SQL Server Driver][SQL Server]Extent (1:136752) in database
ID 2 is marked allocated in the GAM, but no SGAM or IAM has allocated it.
A re-boot solved the problem, but what is causing it?
During daily scheduled maintenance the following error occurs, which causes the maintenance job to fail. How can we fix?
Thanks!

I'm log shipping to AWS. Currently, we are shipping from a server with 64 GB RAM to one at AWS with 30. It's not a massive server but does have periods of high usage when certain jobs/tasks run. It's been running fine for a year but the server size is large and is barely used. My understanding is that for simply log shipping, we don't need a lot of memory and I was hoping to drop the instance size down and use an instance with 16 GB Ram instead. It would save thousands per year.
View 2 Replies View RelatedI would like to ask regarding the memory allocation fo SQL Server 2000. For example if my Data Server have 8GB physical memory installed how much memory can SQL Server 2000 utilize? Based on my research and understing SQL 2000 Server can only utilize 3GB memory? But using the AWE you can set the memory to a maximum server memory?
View 8 Replies View RelatedI’m setting up a server for development that will have one instance of SQL Server 2000 Standard Edition and one of SQL Server 2005 Standard Edition installed.
The server has a total of 3.5 GB of physical memory, so I was wondering about the best way to allocate the memory. Should I just let both instances have the default allocation and let them fight it out for memory as needed, or allocate a memory limit for each instance?
