Turn Sql Serveice Off Before Performing Disk Defrag?
Oct 15, 2007We have a Windows 2003 R2 server running Sql 2005. Should we stop the sql server engine prior to running the "Defrag" utiltiy that comes with the OS? (Maybe we should also disable the NIC card on that machine too....?)
TIA,

2 Servers 1 Disk Drive
Sep 10, 1999I've been asked to configure a "hot-backup" server configuration.
However, I'm coming into the situation a bit later, and they would like me to accomplish the hot-backup with their hardware and their methodology.
Here goes.
We have two identical servers. They will both have a SCSI connection to a device refered to as an "EMC". It will be seen as a single drive letter "E:" to both boxes. Only 1 server will be "up" and using the drive at a time.
The idea is to have SQL devices - (oops, database files) located on the "EMC" drives and in the event of a failure of one server, we bring up the backup and it will take right off using the existing Database files (*.mdf, *.ldf files).
1. Can Sql server 2 come up using databases that have been modified
by server 1. (Provided Master database is on this common drive?
2. What about MSDB, can it be located on a drive different than
where SQL program files are located?
3. How about installing all of SQL application and DB's onto
the Shared Drive? Can a different server come up using the same files?
Anyone out there done/seen/heard of a similar configuration?
Any caveats
Moving Indexes To Their Own Disk Drive
Apr 22, 2004I am trying to find out if it is possible to move indexes to a separate filegroup/disk drive during database restore. I am trying this to see if it improves performance. Also if I cannot move the indexes during restore, how would I move them afterwards to a different filegroup/disk drive? Thanks in advance for all the help.

Jul 7, 2015My data folder of SQL as filled up the space of my local drive. I have 150KB free space left in the drive. So I have to delete some records to regain space.

View 1 Replies View RelatedDo/can Multiple Filegroups Really Make A Difference When Only One Disk Drive Is Involve?
Sep 27, 2007outside of restore manageability, can multiple filegroups enhance performance when only one disk is attached? I guess I should also ask if it can hurt?
I have two use cases and am a bit unclear after reading lots of material on the subject.
My first use case is an OLTP consisting of a very stable set of "configuration" tables and a volatile transaction intake table with RI on the stable tables. I thought about putting the volatile table in it's own filegroup due to it's behavior but am second guessing myself after seeing that every author on the subject seems to hint that filegroups are only relevant when they map to different disks.
My second use case is an archive (readonly) that I will "range" partition due to volume. My first instinct was to create one filegroup for each partition but again I'm wondering what that will buy me in an environment with only a single disk.

Should The Quorum Disk Be A Physical Disk Or Majority Node Set?
Nov 15, 2006Hello,
I am trying to setup a test cluster and am having an issue. When I try to create the resource of a physical disk it takes both the drive e: and drive q: and doesn't seperate them into two physical disks as resources. This means when I try to associate the quorum disk it links the to physcial disk resource of drive e and q. Then when I try to install SQL2k5 I get the warning about installing SQL on the quorum disk. Am I missing something? Is there a way to seperate e and q onto two physical disk resources so I can specifically associate the quorum to q and the sql to e or should I be setting the quorum disk to a majority node set? Thanks in advance.

Can I Used A Shared Drive Rather Than A Mapped Drive With OpenRowSet?
Apr 4, 2008
Hi
I have been trying to use openrowset with a shared drive, and even though the share has "full control" permissions granted to "everyone" and the accout that SQL runs under has been granted explicit full control permissions I am unable to open the file which itself has no security on it.
Can I not use a \ path and only use mapped drives?
Thanks
below works...

Defrag Or Not To Defrag
Mar 14, 2007I have been reading many things on the internet and I wanted to create a thread asking my question here. We currently do all the re-indexing and show contig's etc to maintain my sql data and to ensure everything is good to go there.
My question is, what about the physical drive and data. We house our mdf's on a raid 1_0 and our ldfs on raid 5. I am wondering if I need to defrag these drives b/c if not am i impacting my I/O on that box. If so should I stop the sql service so that it does not corrupt SQL data? Any help on this topic would be great.

How To Move A Log File From 'e' Drive To 'f' Drive....
Nov 9, 2000I am trying to move a log file from one drive to another.
What I have done is add another file to my file group. So now my log has a file on the 'e' drive and one on the 'f' drive. I now want to remove the file on the 'e' drive. I have emptied the file on the 'e' drive. When doing the command:
ALTER DATABASE Uniprodruntime
REMOVE FILE m_rk_runtime_log
I get the following error message..
Server: Msg 5020, Level 16, State 1, Line 1
The primary data or log file cannot be removed from a database.
I have also gone into enterprise manager and tried to delete the file and it does nothing.
Has anyone run into this?

TempDB Keeps Getting Filled And It Is In C Drive But It Should Be In T Drive
Nov 28, 2015Server: SQL 2008 R2
1: TempDB keeps getting filled. Restart of the server has not fixed it. I shrink it, but the space gets filled again. Now I can't even shrink it anymore
2: TempDB is at the wrong location. Its current location is this :C:Program FilesMicrosoft SQL ServerMSSQL10_50.SQLPROD6MSSQLDATA empdb
How do I change its location?

SQL Server, Disk Arrays And Disk IO
May 7, 2004Hi all,
Ok here goes,
I have a three tier system using SQL server 2000, we are currently experiencing IO bottle necks on our SCSI Raid 10 array, which holds the Data and the logs in separate partitions.
So my options as I understand it are:
Get Enterprise edition
or
Get another physical raid 10 array and separate the logs and data i.e. data on one array and logs on the other array.
I would like to try the latter but I am totally unsure how much difference this will make or whether it will make any difference at all.
Does anyone know how much performance increase I will get from using two arrays as opposed to one?
Any other advice on this scenario would be greatly appreciated.
Thanks

Defrag SQL SERVER
Feb 13, 2004Folks
Our sql server machine is badly in need of a defrag however I'm a bit weary of doing this as I'm really not sure of the implications or indeed how to do it.
I'm really not a server type of person so any assistance would be gratefully received. If anyone can explain it to me like I'm a 5 year old then that would probably be best!

Database Defrag
Jul 14, 2004Hello,
I am working with a very large db (850+gig) that is in desperate need of defragging. I am familiar with DBCC Reindex and DBCC IndexDefrag but am concerned that these processes will take an extremely long time to run. Has anyone had any experience with any 3rd party tools that better/faster then DBCC? Or any ideas or suggestions how best to attack this? Among the many tables with large footprints and millions of rows, I have 3 tables with reserved space over 100g also 3 tables with over 500Mil rows (1 tbl with > 1bil rows). This is a 24x7 db.
Thanks in advance for any ideas and suggestions

Defrag / Reindex
Oct 21, 2007I#ve been doing disaster recovery on a web box that died today.
So I thought I'd do some "downtime" maintenance on the DB server
I ran a BDREINDEX on all tables, all indexes. (I know this is the 2000 way, but I assume its as good as the proper 2005 way??).
5 minutes on a 10GB database. Not bad!
I checked the DEFRAG and UPDATE STATS processes that run overnight.
They are basically defragging only tables with SHOWCONTIG indicating fragmentation. And then doing an UPDATE STATISTICS WITH FULLSCAN on all tables
That is taking an average of 30 minutes ...
Is DBREINDEX the equivalent of an UPDATE STATISTICS WITH FULLSCAN, or is it in some way a smaller-sample version?
I'm wondering why I don't just lock the DB and do a REINDEX of everything in 5 minutes ...

Aug 22, 2007Is there any easy way to defrag a table with no clustered idx other than bcp out then back in ? (SQL 2000)Actually I have a 100GB db that I deleted data from other tables, about 10GB worth, but access to the table in question (38GB) seems to have slowed down dramatically, Or does the entire disk need to be defragmented and a bcp out/in would be a waste of time on this table ?I run an index defrag every night, reindex weekly.Thanks.

I use the REORGANIZE option of ALTER INDEX. It's default is ONLINE, no matter what the engine edition and makes for simpler code.
I also make heavy use of my own logging tables, which are included at the bottom of the sp.

Index Rebuild Does Not Defrag
Oct 3, 2007Hi,
After issuing an index rebuild on a primary key index (and updating statistics), the index still shows a scan density of 12.5%!
Any ideas on why the rebuild doesn't seem to do anything on the fragmentation levels?
I'm using sql 2005
Thanx
Moving A SQL Server 2000 Database From A Local Drive To Another Local Drive
Jan 31, 2008Being a very novice SQL Server administrator, I need to ask the experts a question.
How do I go about moving a database from 1 drive to another? The source drive (C is local to the server, but the target drive (E is on a Storage Area Network (SAN), although it is still a local drive for the server. I want to move the database from C: to E:. Can someone provide me with instructions?
Thanks,
Rick
