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
Please find the necessary SQL scripts to generate a small version of my database and some data at the bottom of this post.
Here's a short description of what the database is all about: It's a project tracking and management system. Contracts go into the tblDeals table. Because each project may be different in nature, project phases are defined in tblPhaseType and tblPhase tables. The table used to keep track of what's going on is the tblProduction table.
Here's what I need to do. When a project is completed -- meaning it has gone through all the phases that it needs to go through -- I want a trigger to fire up and change the contract status in the tblDeals table to "Completed" whose value is 1. When a new contract gets entered into the table, the Contract Status is set to 5 by default which means "In Progress" -- as defined in tblContractStatus. The tricky part is that because, each project is different and has different number of phases, the trigger has to make sure that all the phases have been submitted into the tblProduction table for that particular deal.
I'd really appreciate some help here. Thanks in advance for all your help.

Experts: Please assist with coding a trigger for a SQL Server 2005 .NET application.
Here's the scenario:
Suppose there are tables MEMBERS, ACTIVITY, and HEADCOUNT that look like this:
MEMBER
member_id (int)
member_name (varchar(50))
...etc
ACTIVITY
activity_id (int)
activity_name (varchar(50))
...etc
HEADCOUNT
headcount_id (int)
member_id (int)
activity_id (int)
...etc
Suppose also that the ACTIVITY table is already populated with several records, say with activity_id = 1, 2, and 3.
OBJECTIVE: When a new member record is added to MEMBER, say member_id 10, insert one record in the HEADCOUNT table for EACH activity in ACTIVITY for that member. Thus, if member #10 is added to MEMBER, then the trigger (or some other mechanism) would add the following records to HEADCOUNT (which, say, already has 30 records):
headcount_id member_id activity_id
31 10 1
32 10 2
33 10 3
I've been advised that a trigger should do the trick for this, but as I'm totally new to SQL, I'll need some help. I'm guessing some iterating SQL command language might be required, but as I'm new to SQL, I don't know how to proceed.
Note that I'm building an ASP.NET application based on VB, and so records will be added to MEMBER through a tableadapter INSERT command. (Though I suspect this has no bearing on trigger behavior.)
Much obliged for your assistance.

I am developing an application in vb.net 2005 using SQL Server 2000.
In this I have two tables SessionMaster and SessionChild.
Fields of session master - SessionMastId, Start_Date, End_Date, Session_Type,
Fields of session child - SessionChildId, SessionMastId, UserName, Comment.
SessionMastId and SessionChildId are primary keys of respective tables and also they are auto increment fields.
Please how to write trigger to insert record into both tables at a time.
Are there any issues with installing SQL 2000 on a server with Dynamic Disks configured with RAID 1 Mirroring ? I know that with Dynamic Disks there are no partitions but rather volumes. Is the drive configuration setup the same way ?. Would I setup a volume for the O/S and a volume for SQL ? The reason I need to use Dynamic Disks is because we will be integrating it later with an EMC SAN solution.

Can both be used with SQL server ? Dynamic disks provide more flexibility, is there performance imact ?
Thank you.
Hello,
I have a two node SQL 2000 cluster running on windows 2003 enterprise server. We need to replace the SAN disks. Can we not disable SQL service & Cluster service, copy the contents from existing disks to target disks, swap the drive letter & start the services?
What is the best practice to do this? Appreciate your help.
Thanks

I have a new server.
It was shipped with a 76 gig drive setup in RAID 1 (2 disk) and a 400 gig drive setup in RAID 5 (4 disk).
I would like to determine what is the best way to setup up the partitions. What size and what should be placed on each.
Like the C: Drive...Should I just put Windows on there and nothing else? Do I stand to gain something from not using part of that 76 gigs as a D: drive for my apps?
I am trying to build the 2 node 2 clusters with the AlwaysOn.
Here isthe landscape.
2 nodes PROD failover cluster (running once instance)
2 nodes DR failover cluster (running 2 instances - DR and PRE-PROD)
Both clusters are in different geographies.
PRE-PROD can be editable. So out of scope of Always On.
One instance on PROD -> DR of the other box. [Want to achive thru AlwaysON]
Now my Question:
1) Do i need to have all the 4 nodes in same failover cluster group? If yes, then this would become MultiSubnet cluster Or Is there any way those 2 diffrerent failover clusters (one DR and one PROD) can be part of AlwaysOn.
2) Can i use the clustered disks as in the above landscape for always on?
Hi All
I am in process of moving a SQL 2005 solution from a development box that used local storage to UAT environment with SAN attached storage. The solution uses database snapshots
The database files are on the SAN storage but during testing I was unable to create a Database snapshot on the SAN disk. Creating snapshots on the local disk worked fine.
Is their some restriction/problem in using the database snapshot technology with SAN storage?
I've read that if particular tables are frequently queried together through a join then these tables should be placed on different devices on different physical disks.
What does this mean exactly and how would you configure this?
Is this a common practice in high-performance real-world environments (or should it be)?

I have a software that presents a drive to a 2 node cluster.
Not sure how I would go about presenting this newly presented drive as a Cluster Resource and make SQL depend on this resource.
Why I see absolutely no performance improvement when I spread my primary file group over 8 separate files on 8 separate disks, as opposed to having the primary file group all in one file on one disk.
I have set up 2 identical databases, one spread over 8 disks and one on one disk. Each database has a table called DATA and a column called VALUE. Value is NVARCHAR(200). I have filled each table up in both databases with 20,000 rows.
I then perform a select on each table in each database using CHECKPOINT and DBCC DROPCLEANBUFFERS to ensure I am reading from disk before each query and the execution times are identical in both databases.
I then ran the same queries against each database using a load testing tool and the batch requests per second on each DB is identical under load.
Surely the database with data spread over 8 disks should be FAR faster than the single file database as you have the combined reading power of 8 disks as opposed to 2??
Also, the same is happening for write speeds. When I create the data on both databases, the time it takes is identical on both.
BOL says it should be faster with multiple disks.
Just FYI this is on an Azure virtual machine and each disk is a locally redundant data disk that I have attached to the virtual machine.
Whether write speeds should increase with multiple disks or just read speeds?
I am getting following errors in my Cluster Validation report when trying to create a Windows Cluster.

I am wondering what would be the best disk/RAID setup for a Windows server 2008 R2 OS and SQL Server 2012 database that has heavy read/write. I have the following disks I can use:
4x 15k 146GB
2x 10k 600GB
According to the server build requirements for the application, I need 100GB for the OS and 290GB for the drive containing the SQL mdf there are no stated requirements for the ldf, but would like to know if it should be allocated elsewhere?I should do RAID 10 for the 15k drives for SQL and RAID 1 for the OS on the 10k.
I am testing out a blank database created over two physical files on two separate disks with one table called data which has one column called values nvarchar(max).
I filled the table up with a whole load of data and ran a select * against it. If I run Permon at the same time I can see that the read load has been spread over multiple disks as each of these disks is getting read from in parallel. If I create the same database on a single file and run the same select * again it takes much longer, proving that the read load has been distributed across multiple disks.
Now moving onto writes, this is where the confusion lies. I understand that SQL server fills files evenly until they need growing, after which it will then fill files individually until they are full in a round robin fashion unless you have trace 1117 turned on. What I don't understand is why the writes aren't distributed out whilst it is filling these file groups.
I ran an continual insert into my table with go 1000000 to monitor how the files are being filled up. I monitored where SQL server was physically placing the files as they were being inserted by running the following query:
;WITH CTE AS
(SELECT
sys.fn_PhysLocFormatter (%%physloc%%) col1,
RIGHT(LEFT(sys.fn_PhysLocFormatter (%%physloc%%),2),1) AS [Physical RID],
DATAID
[Code] ....
I could see that it would a thousand or so records into file 1, then a thousand or so into file 2, then a thousand or so into file 1 etc etc. In another words it would hit one disk, then another disk, then back to disk one to fill the file evenly. Is there any way to make SQL Server distribute the writes out in parallel so that both disks are writing in tandem?
By the looks of it, multiple disks only scale reads, as with writes only one disk is ever written to at once which is annoying. Any way to harness the write power of multiple disks?
hi,
I am new to this technology. can anyone pls help me.can anybody tell me what is physiacl file and source physiacl file wat are the attributes of physical file and source physical file.and how do we identify the uniqueness of a job.
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

Hi! I have an SQL server installation with a 6.5GB database online at a particular location. I need to move the Database to another location which is a 1000 Miles away.
I have an additional physical Server at the other location which I can use to Sync the database from the original location. Can anyone please guide me to the best strategy to sync the database from the original location to the new location with minimum downtime??
Any help would be greatly appreciated.
Thanks and Regards

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?

Hi,
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?

we have:
(1) one physical server :
OS : Windows Server 2003
Active Directory, DNS, DHCP, File Server, Print Server and SQL Server 2005
and we will install new (2) two server for High Availability with VMware vSphere (ESXi) 6.0
and we will have (2) two Virtual Machine :
1st VM :
OS : Windows Server 2012 R2
Active Directory, DNS, DHCP
2nd VM :
OS : Windows Server 2008 R2 (becaure SQL Server 2005 does not work with 2012 R2 link)
SQL Server 2005 Service Pack 3
My Question is : What is a safe method to Migrate Database's from Physical Host (Windows Server 2003) to 2nd VM ?
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.

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.....

View 2 Replies View RelatedI 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,
View 3 Replies View RelatedI 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
