Using DISKPART For Disk Alignment And Understanding Output
Apr 7, 2011
I understand that in 2008 server it'll align the disks for you automatically. I've run the following commands on another one of my DB servers and the offset was 1024 on all of them. I get the following from my other DB server and it doesn't list the alignment on every partition save the first one.
DISKPART> select disk 0
Disk 0 is now the selected disk.
DISKPART> list partition
Partition ### Type Size Offset
[code]....
Need to verify that all is fine with my file system or do I need to repartion everything? My DB servers are in a virtualized environment using EqualLogic and VMWare.There is always a way...
When creating a new disk partition for SQL Server on a SAN (RAID 5) do you use Diskpart with the Align= parm to keep from doing two physical I/O operations for each logical I/O?
hello,all I am new to Sql 2000,I installed sql 2000 database in C disk,but Now I found my C disk space is smaller than before,So I want to move my databse(include data and structure) from C Disk to D Disk(its space is very large) . is it possible to do it ? if its can be done ,do I need to change my asp.net program source code (exp: chaneg my crystal report connectstring ) ? thanks in advanced!
If I return the Average, Minimum, and Maximum values for the counter Physical Disk: Avg. Disk Queue Length, and those values are 10, 0, 87 respectively, which value do I use to compute the Avg. Disk Queue Length for a 4 disk array(RAID 10): Average, Minimum, or Maximum? The disk(lun) is on a SAN.

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.
my server is sqlserver 2005. iam writing sps in sql 2000 . if i open in sql 2005 the alignment of my sps is changed. i have changed the tab order of 2005 as equal to 2000.then also the problem comes. so plz give me solution to solve the problem.
When making a report with VS2005, things get spaced out wierd and dropped down when deployed to the web?
I can't get things like images to position properly. Does it have anything to do with the fact that I am using a Matrix?
For example, I create an image and embed it, I have it all the way to the left of the form and when deployed it is more towards the middle of the page?
Very frustrating, just wondering if anyone has any tips/solutions.
After i upload the report to server , and try to convert it to excel, the alignment of report is out!!the width of columns is different with the width i set in design..=.= however, the report is pretty when i preview in reporting servcise design.
Hi All, I am working on a report, in this report a textbox is present, which is expected to show string. This string length is larger than what textbox can accommodate in single line. I want this textbox to show only right part of the string in case it can accommodate full string. After using the right alignment I assumed it would do show, however it does not work like that. It always shows the left part of string in case, string is bigger than width of textbox. Restriction from design: 1. Cannot increase the width of textbox. 2. Cannot use the Can Grow = true to show string in multiple lines.
Below is the example of my issue: Say there is a string: "Microsoft SQL Server Reporting Services". because the textbox width is not sufficient to see full string, I want to "Reporting Service". Which is of same size which column can accommodate. So I used Right alignment in textbox. however text box shows "Microsoft SQL Server". So, is there a solution to see required text in the textbox.
Greeting I have more than one language installed on my computer, and I tried to use my Enterprise Manager yesterday... What Im getting is with all the GUI im using Im having everything is Right Aligned..... Any help as to what I should change? Thanks This is my first post so would be great to have a qucik and handy answer :D
I am representing negative number within parenthesis , but as I am working on reporting service, it is possible to make the exact alignment of the number and parenthesis.
here is one example .... when i format number with #,##,0;(#,##,0) i am getting output in a format in subsequent rows like
123,345 (145,567)
How can I make this alignment like
123,345 (145,567)
where the parenthesis will be outside the number space keeping in mind the alignment is in right .
I just can not understand why when I add text to a group header the report displays more group row space but when I export to excel the extra space disappears....
I've yet to use partitioning in a production environment, and pretty much last ran any partitioning related code a few years back when looking at certification; so I'm definitely not an expert on the matter and only loosely clued up on the concepts.
I've recently started with a new employer, and they have just implemented a new system for sms messaging. The database tables tracking the sms messages being sent are going to get big and so they have created decided to implement partitioning on some of the tables using a partition scheme on the CreatedDate column; the DBA involved in designing the partitioning has left and I'm picking this up.
There are some issues with the above that I will be addressing seperately (e.g. the clustered index should be unique as it contians the unique key, and the fillfactors are daft), but my concerns for this post are below.
1) How to define the Primary Key and enforce it's uniqueness whilst trying to ensure it's aligned with the partition in order to be able to switch out old data once an as yet undefined retention period has passed. In books online it states:- "If it is not possible for the partitioning column to be included in the unique key, you must use a DML trigger instead to enforce uniqueness. " Books online - Special Guidelines for Partitioned Indexes. However, I'm not sure what this means, nor how I create the primary key to use the partition function seeing as it doesn't have the CreatedDate in the unique key?
2) The original partition function was envisaged as the following:-
CREATE PARTITION FUNCTION [DateFunction](datetime) AS RANGE LEFT FOR VALUES (N'2014-01-01T00:00:00.000' , N'2014-04-01T00:00:00.000' , N'2014-07-01T00:00:00.000' , N'2014-10-01T00:00:00.000' , N'2015-01-01T00:00:00.000' , N'2015-04-01T00:00:00.000' , N'2015-04-02T00:00:00.000' , N'2015-04-03T00:00:00.000' , N'2015-04-04T00:00:00.000' , N'2015-04-05T00:00:00.000') GO
There is a procedure that has been created and scheduled daily that will create a new partition for each day, and then merge these together at the end of the quarter. My understanding of partitioning is that this is a bad idea, as it will result in merging several populated partitions together. Is my understanding correct? If so, I'm planning on removing the day partitions at the end of the function, and simply adding quarterly partitions, maintaining a spare empty partition at the end of the table. Would this make more sense?
Can we have more than 2 parameters displayed in a single row on report (when browsed using web browser). The parameters BY DEFAULT - seems to be lined up in an array of 2 columns, and N rows - which gets frustrating because so much of space is left blank (gray space just left of <View Report> button and to the right of parameters line-up).
How can we have more than 2 parameters displayed in one single row ? As this will help the actual report content to take up more space on the screen than the parametes taking up almost 1/2 of the screen.
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.
Relative newb to SSRS here, but the answer to this question evades me; answers and insight are appreciated.
Report in question is an invoice form. It requires an absolutely bottom-of-page aligned footer that has databound elements.
This is so that whatever page that footer finally appears on will print in such a way that the address will align in a windowed envelope.
Ironically, Books Online gives this exact scenario in explaining headers and footers in SSRS, but they cleverly don't explain how an absolutely bottom-of-page-aligned and data-bound footer can be made to happen. Headers at absolute page top is obviously no problem. Footers at page bottom, not so much.
So, this is not a "page footer"--page footers are employed in the body. Also this footer is databound, so a page footer as it's known in SSRS is out the window anyway.
Most of the time this will print on a single page, but if it breaks to multiple pages, that footer needs to go all the way to the absolute bottom.
I grasp that the "report footer" for SSRS is just what appears at the end of any repeating controls that you've implemented in your body. Because SSRS uses this kind of repeating-control based idiom rather than a section-based idiom as Crystal does, this kind of (what I would consider very basic) positioning control is looking fairly impossible right now.
Among what I've tried:
--Page footer (can't; databound)
--Specifying a page break after the pre-footer controls, and/or a page break before the controls that make up the footer in their properties. This leads to unpredictable results with blank printed pages (as many as 8 for what previews as a 2-page report, how silly is that?).
--Putting in a page-height rectangle as part of the footer (with and without the page breaks mentioned above), with the idea of forcing a basically blank page at the end of the report so that the footer will go to the bottom. SSRS will go ahead and break the page anyway on long elements like that, which again leads to the "footer" being printed in the middle or top of the final page, or whereever it happens to fall.
I may be having to explain to my client that you can't get there from here, and they may have to redesign their report. Does anyone have any insight?

The following SQL is lifted from one of the Reporting Services / Adventureworks2000 sample reports. I'm a little slow / baffled on how the inner joins are working? Specifically the Inner Join Locale and Inner Join ProductModel. I'm used to seeing Inner Join SomTable On Something = Somthing but how these joins are working is lost on me. Can someone give a quick overview (or point me to a reference) so I can better understand.
Thanks!
SELECT ProductSubCategory.Name AS ProdSubCat, ProductModel.Name AS ProdModel, ProductCategory.Name AS ProdCat, ProductDescription.Description, ProductPhoto.LargePhoto, Product.Name AS ProdName, Product.ProductNumber, Product.Color, Product.Size, Product.Weight, Product.DealerPrice, Product.Style, Product.Class, Product.ListPrice FROM ProductSubCategory INNER JOIN Locale INNER JOIN ProductDescriptionXLocale ON Locale.LocaleID = ProductDescriptionXLocale.LocaleID INNER JOIN ProductDescription ON ProductDescriptionXLocale.ProductDescriptionID = ProductDescription.ProductDescriptionID INNER JOIN ProductModel INNER JOIN Product ON ProductModel.ProductModelID = Product.ProductModelID INNER JOIN ProductModelXProductDescriptionXLocale ON ProductModel.ProductModelID = ProductModelXProductDescriptionXLocale.ProductModelID ON ProductDescriptionXLocale.LocaleID = ProductModelXProductDescriptionXLocale.LocaleID AND ProductDescriptionXLocale.ProductDescriptionID = ProductModelXProductDescriptionXLocale.ProductDescriptionID ON ProductSubCategory.ProductSubCategoryID = Product.ProductSubCategoryID INNER JOIN ProductCategory ON ProductSubCategory.ProductCategoryID = ProductCategory.ProductCategoryID LEFT OUTER JOIN ProductPhoto ON Product.ProductPhotoID = ProductPhoto.ProductPhotoID WHERE (Locale.LocaleID = 'EN')
I'm trying to get the following poll working:http://www.codeproject.com/useritems/Site_Poll_Control.aspIt looks like it's exactly what I was looking for, but it doesn't come with much in the way of instructions. I have the following function: Public Function CastVote(ByVal PollId As Integer, ByVal Answer As Integer, ByVal MemberId As Integer) As Boolean Dim cmd As New SqlCommand("InsertPollResult", New SqlConnection(Connection)) With cmd.Parameters .AddWithValue("@PollId", PollId) .AddWithValue("@PollChoice", Answer) .AddWithValue("@MemberId", MemberId) End With Return (SqlExecuteInsertSp(cmd) > 0) End Function This calls SqlExecuteInsertSp(cmd) which is:Public Function SqlExecuteInsertSp(ByVal cmd As SqlCommand) As Integer Dim i As Integer cmd.CommandType = CommandType.StoredProcedure Try cmd.Connection.Open() i = cmd.ExecuteNonQuery() Catch ex As Exception ErrorMessage = "ProDBObject.SqlExecuteInsertSp(SqlCommand): " & ex.Message.ToString Finally cmd.Connection.Close() End Try Return i End Function I can't figure out what this is doing. The best I can figure is it determines if we have a good connection. Is this right? In my code CastVote keeps returning false, and I don't know why. The answer seems to be in the i = cmd.ExecuteNonQuery() line, but I can't figure out what that line is supposed to be doing.Diane
Hi Guys, I have written quite a big stored procedure which creates a temporary table (multi-session) and updates it. All the statements are encapsulated in a single transaction which is explicitly declared in the code. What happens is that a lock is being put by the server on that table (of type Sch-M) in order thus preventing any type of operations on it (including simple select)
Now, I want to be able read that table from within another transaction. Why is that I cannot use a table hint NOLOCK in the select statement?
Here is some code which reproduces my problem.
Query A:
SET TRANSACTION ISOLATION LEVEL READ UNCOMMITTED;
BEGIN TRAN TR_DEMO;
CREATE TABLE ##TBL1( Oidx int not null primary key identity(1,1), Name nvarchar(30) not null, Type char(1) not null );
My question is in what situations @@ERROR will be set...
I like to do some logic when some error is occured in a particular statement....
the doc. says the @@ERROR value will be set if an error occurs in a statement, and the control will move to the next statement without exiting(???) the procedure and @@ERROR value can be used in that statement.
but when i execute the below procedure, the execution is terminated ( when the error occurs) without moving to the next statement. please help me to understand the SQL Server's @@ERROR and the situations when it will be set....
----------------------------------------------------------------------- CREATE PROCEDURE VALUE_ERROR_TEST AS BEGIN DECLARE @adv_error INT DECLARE @errno INT DECLARE @var int SELECT @var = '101 a' SELECT @errno = @@ERROR print @errno END go ----------------------------------------------------------------------- procedure get successfully compiled. when executed it says,
Server: Msg 245, Level 16, State 1, Procedure VALUE_ERROR_TEST, Line 10 Syntax error converting the varchar value '101 a' to a column of data type int.
Please consider the following example.CREATE TABLE test (an_ndx int NOT NULL primary key identity(1,1),a_var varchar(48) NOT NULL,last_edit_timestamp datetime NOT NULL default CURRENT_TIMESTAMP);CREATE TABLE test_history (an_ndx int NOT NULL,a_var varchar(48) NOT NULL,last_edit_timestamp datetime NOT NULL,current_edit_timestamp datetime NOT NULL default CURRENT_TIMESTAMP);GOCREATE TRIGGER update_history ON test FOR UPDATEASBEGININSERT INTO test_history (an_ndx, a_var, last_edit_timestamp)SELECT * FROM deleted;UPDATE inserted SET last_edit_timestamp = CURRENT_TIMESTAMP;END;The question is, does this do what I think it should do? What Iintended: An insert into test results in default values for an_ndx andlast_edit_timestamp. An update to test results in the original row(s)being copied to test_history, with a default value forcurrent_edit_timestamp, and the value of last_edit_timestamp beingupdated to the current timestamp. Each record in test_history shouldhave the valid time interval (last_edit_timestamp tocurrent_edit_timestamp) for each value a_var has had for the "object"or "record" identified by an_ndx.If not, what change(s) are needed to make it do what I want it to do?Will the trigger I defined above behave properly (i.e. as I intended)if more than one record needs to be updated?ThanksTed
I am using SQL Server Express and Visual Studio 2005. I am new to batches and am trying to understand how they work. I am trying to write a query that creates an assembly and the functions that are contained in it. Here is my query:
USE ProductsDRM GO
IF NOT EXISTS (SELECT 'True' FROM sys.assemblies WHERE name = 'ComputedColumnFunctions') BEGIN CREATE ASSEMBLY ComputedColumnFunctions FROM 'C:WebsitesAssemblyTestStoredFunctionsStoredFunctionsinStoredFunctions.dll' GO
CREATE FUNCTION fImageFileName ( @ProductID int, @ImageSizeCode nvarchar(4000) ) RETURNS nvarchar(4000) AS EXTERNAL NAME [ComputedColumnFunctions].[StoredFunctions.UserDefinedFunctions].ImageFileName GO
CREATE FUNCTION fTestInt ( @ProductID int ) RETURNS int AS EXTERNAL NAME [ComputedColumnFunctions].[StoredFunctions.UserDefinedFunctions].TestInt GO
CREATE FUNCTION fTestInt2 ( @TestInt int ) RETURNS int AS EXTERNAL NAME [ComputedColumnFunctions].[StoredFunctions.UserDefinedFunctions].TestInt2 END ELSE BEGIN PRINT 'The assembly named "ComputedColumnFunctions" already exists. No new assembly was created.' END
GO
I read in a book about SQL Server 2005 about including a test for whether the object (such as assembly in this case) exists before trying to create it. If I only include the CREATE ASSEMBLY statement and the FROM line below it and delete the next GO down through the last CREATE FUNCTION (just before the END ELSE), it works fine. If I leave it as is, I get a runtime error on the GO line just after the CREATE ASSEMBLY statement. What am I doing wrong?
I have a situation where I need to distribute a db to 'subscribers' for use during network, and preferred application downtime. Currently, we do this by employing MS-Access. We update our db on the 'subscriber' by sending a text file with the new data using FTP.
When the 'subscriber' opens their local copy of the Access db application, a macro fires off to check for any new file in the ftproot folder, and if one is detect that is newer than the last update, it truncates the existing table, and imports the text file using a predefined import specification format. The process works well enough as is. However, we were hoping to move beyond our dependency on MS-Access for a variety of reasons, so we are looking at developing windows forms apps using the new Asp.Net v2.0 technology and Sql2005 and SqlExpress.
I need some clarification on how replication works. Does it allow a 'snapshot' db to be created on a subscriber that can be used when the network is down? If not do we have alternatives? For example, I guess we could export/import to the subscriber in some manner.
Hope I've made the case clear enough for some responses. Thanks in advance for your thoughts and help. :)
Please forgive the basic-ness of my question, but I have only been using DTS and SSIS for 2 weeks now.
What I'd like to know is, is my understanding of SSIS package development correct.
In SQL Server 2005, I use BIDS to develop my SSIS packages. During development, I simply store my project on the local C drive.
However, once I am finished writing and testing my projects, I move them to SQL Server, using SAVE COPY AS... (for now, I only using one server for both development and production)
Then, anytime I need to change or modify the package, I change the local file system copy of the package, then do another COPY AS... to SQL Server.
That is, once the package is on SQL Server, if you need to change it, you can only do so through BIDS, correct?
I just want to know if I'm on the right track here.
