Migration To Another Physical Location

Apr 4, 2008

I may be put on a project involving the migration of a SQL Server 2000 database from one physical location to another. I've never done something like this so any guidance would be appreciated.

My plan is to:
1. Backup the live database.
2. Do a restoration at the new location.
3. Set up transactional replication between the two databases.
4. Update records to point to the new db.

Are there any problems with doing it this way? Is there a better solution? I am trying to do this without any downtime, or as little as possible.

Thanks for any help.

SQL Server 2008 :: How To Update The Database Physical File Location In Master Database

Mar 8, 2015

I had to to relocate the database log file and I issued an Alter database command but by mistake I put a space in the file name as below. The space is at the beginning file name. Now I am unable get the database loaded to SQL Server. The database has 2 replications configured, so deleting and re-attaching the database means the replication needs to be re-configured. Is there an alternative way to issue a command to update the database FILENAME ? Not sure if this can be edited in master database (sys files).

ALTER DATABASE [User_DB]
MODIFY FILE (NAME = User_DB_log, FILENAME = 'I:SQLLogs User_DB_log.ldf')
GO

Combining Physical Files

Feb 28, 2001

Can anyone inform me how I would go about merging or combining 2 or more physical database files into 1. For example, suppose you have the following files out on your server:

c:mssql7datapubs_data1.mdf
c:mssql7datapubs_data2.ndf
c:mssql7datapubs_data3.ndf

but you only want

c:mssql7datapubs_data1.mdf

Is there any way to combine pubs_data2.ndf and pubs_data3.ndf into pubs_data1.mdf so you are only left with 1 database file called pubs_data1.mdf?

Thank you,

PJ

I know how to modify the logical file name: ALTER DATABASE SATutorial
MODIFY FILE (NAME = Tutorial, NEWNAME = SATutorial_data)
GO

How would I modify the physical file name from (e.g.) Tutorial.mdf to SATutorial_data.mdf?

TIA...

Bit Datatypes Physical Storage

Feb 15, 2005

Can anyone explain to me how a column defined with a "bit null" datatype is physically stored in MSSQL? Is it stored like a "tinyint null" physically? In other words, how many bytes on the row on the page does a "bit null" datatype consume (assuming a non-null value 0, or 1 is the current value).

Is there any good documentation about the physical storage layout for a data page?

Thanks -

I have a new server where 32GB of RAM is installed and I have user databases on this server.I am using SQL server 2000 Enterprise edition and Platform is Windows 2003 adv server, which supports upto 128GB of memory.

sp_configure 'awe enabled' is set to 1 and at OS level, AWE is enabled as well.

max server memory (MB) is 2147483647

I was doing some stress test on this server but memory usage doesn't go beyond 180MB....can someone suggest a test for physical RAM ?

How can I make sure that application will make full use of available physical memory?

Physical Disk Partitions

May 21, 2007

I just inherited a dev box, and need to do some performance analyzing on a 40 gig db for a client. Time is of the essence!

My question is that this dev box only has one disk partition (c: drive). Is it a huge deal that I don't have the db system files on one drive, with the data files on another, and tempdb on another,etc.....

SQL Server 7 Physical Storage

Jul 23, 2005

I need to bulk insert very large amount of data into several MSSQLtables.The first Data model definition used identities to mantain relationshipbetween those tables but we found that natural keys (compound) arebetter forbulk insert (there is no need to obtain the identity first)My question is, changing the identities to natural keys (in some tablesinorder of 4, 5 attributes) will enlarge my database storage?I think MSSQL implements relationships with pointers (or hashcodes), sothestorage size will be similar, right?Regards,

Looking For Physical Design Suggestions...

Jul 20, 2005

I got a server that has a RAID-5 array partitioned into C: and D:drives (OS Win2K Adv. Server installed on C:). The server also has amapping to a NAS device using the latest protocols that trick thesystem into thinking the map is actually a local SCSII drive. That'sdrive X:.This server is used only for SQL, and contains an OLTP database thatsees a lot of use and is pretty heavily indexed.I am toying with the idea of centralizing my data storage on the NAS(data center network segment is 1-gigabit ethernet). So I wasthinking about putting my primary data file on the NAS (drive X:) andkeeping all tables there, creating a secondary data file on localRAID-5 (drive D:) and putting all non-clustered indexes there, as wellas keeping the tempdb there and specifying the sort in tempdb option.Log files would also remain on D:.If anyone can suggest a better scenario given the above setup - I'dlove to hear it. Much appreciated.Alexey Aksyonenko

Physical Memory 198,250K Available

Aug 30, 2007

We have a sql 2005 server with 8GB of RAM. Task Manager shows that it only has 198,250k (about 200 MB) of Physical Memory available. I wonder if that number should be higher.

What can I check (Perfmon counters? Which ones?) to indicate it that's too little RAM, the right amount, or too much.

Thanks,

Unable To Open The Physical File.....

Apr 7, 2006

Hi, i'm trying to interface a c# application with an sql database created with Visual Web Developer Express.
I have published the site (and the db) on iis 5 (xp pro).
Everithing goes fine on accessing the database from internet,but when i try to connect the db while it's opened with my c# program i keep an error in the sqlconnection open command:
Unable to open the physical file "C:myApp_Datamydb.mdf". Operating system error 32: "32(The file is in use by another process.)".
My connection string from webconfig:
<add name="MYDBCS" connectionString="Data Source=.SQLEXPRESS;Database="C:myApp_Datamydb.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True"
providerName="System.Data.SqlClient" />
.....and the connection string for the c# program:
"Data Source=.\SQLEXPRESS;Database=c:myapp_datamydb.mdf;Integrated Security=False;Connect Timeout=30;User ID=abc;Password=abc;Trusted_Connection=False;";
I have used a user to connect the database because there was a conflict trying to open the db with Integrated Security=True.

Does anyone have an idea where is the error?
Many thanks
Max

Trigger Writing Across Physical Disks

Feb 27, 2001

Any help appreciated!
Is there any performance enhancements to be gained by storing frequently 'trigger-written-to' databases on a seperate disk to the source database? In particular, we keep a 'history' database of all inserts/updates/deletes against records, activated by triggers, and I was wondering if I would gain performance enhancement by locating the two databases on different disks?
Thanks in advance

Actual Physical File Size

Jun 21, 2004

Hi Everybody,
I like to compute the actual physical database file size using queries.

From the EM database properties, the file size shown is not matching with the master..sysaltfiles.size

Ex. Actual file size is 12MB and 1MB for MDF & LDF respectively.
'sysaltfiles' shows 1464 & 96 resp. Since they are shoing it as 8K Pages,
96*8 = 768KB is not matching with 1024KB for the LDF file.
Is there any overheads (additional space from the physical file for file headers) allocated?

Thanks
Babu

Moving A Database To Another Physical Disk

Jun 7, 2006

I want to move 2 databases to another physical disk. They are both single file databases. It looks like a fairly straigtforward attach and detach procedure, but I have a couple of questions:

The log files (.ldf) currently reside on a separate physical disk from the data files, if I attach and reattach the data files will the logs remain where they are by default or do I have to re specify there location?

Is there any advantage to running the update statistics portion of the sp_detach_db?

Multiple Backslashes In Physical File Name

Oct 2, 2006

Accidentally, I've managed to have this as part of a Create Database:

... FILENAME = N'C:MSSQLData\ estdb_Log.LDF' ...

, notice the triple backslash. The Create Database statement works fine,
and sp_helpdb says the log file name is:

C:MSSQLData\ estdb_Log.LDF

I noticed the MSDOS command prompt also allows multiple backslashes,
they're reduced to one when performing the command and I guess
SQL Server does the same thing, so no problem so far really.

But is it supposed to work this way? Quite confusing, isn't it?

Weird Physical Disk Access

Jan 28, 2004

Hi,

I have an MS SQL 2000 server running on a Proliat with two CPUs and 2GB RAM (the process actually uses 1.6GB).

For some reason, the same queries (which return the same data) run sometimes very fast and sometimes very slow.

I used the performance counter to find out that when the queries run fast there is little disk i/o and when they run slowly there is a lot of i/o.

I thought it happens because the DB keeps swapping tables in and out of RAM. The problem is that these things happen in periods. I can have a few hours of slow access and then a few hours of fast access. This makes me believe that it doesn't actually put the table in the cache untill it is requested enough times. Very weird.

HELP?

Thanks.

Using DMO To Restore To New Database And Physical File

Mar 19, 2004

I have been trying to use DMO(C++) to backup a database and then restore from that backup to a new db name AND physical data and log files, with no success. I have been able to successfully restore the backup to the same database and change the physical file names using the RelocateFiles property on the Restore object, but not change both.
Any help would be greatly appreciated.

Move Log File To Another Physical Disk

Jul 13, 2007

Hi everyone,

Due to running out of disk space and reducing I/O contention, I plan to seperate data files and log files to different disk arrays.

My plan is to
- detach all databases
- copy log files to another disk
- attach all databases

The total size of log files is about 60GB. It becomes a problem becasue it spend too much time passing files. To reduce down time, is there any way I can do?

Can I just create new log files and remove the current files by using sql management studio?

any other suggestions? Thanks in advance

They physical size of the database is approx. 50GbI am planing to migrate the database to more powerful server. Myquestion is on the new server would we get any benefit from have say 5x10 Gb file for the database as opposed to a single 50GB file.The database will have exclusive access to RAID 10 array withdedicated controller for the data, another array for the T.LogAny thoughts hints would be very helpfulThanks

Adding More Physical Memory ... Do We Need To Upgrade The OS?

May 24, 2008

We are currently running a server with standard edition Windows Server 2003 R2 with standard edition SQL Server 2005 SP2.

The server has 4GB of memory of which 3GB is dedicated to SQL and 1GB to the OS via the use of the /3GB switch.

If we were to increase the physical memory to 12GB (and carve out 2GB for the OS and 10GB for SQL) would we have to upgrade the OS to Enterprise version to access the additional 8GB of memory we plan to add?

Thanks ALL!
