Reads / Writes Per Second.
Oct 30, 2006How can You find the reads and writes per second of your hard drives in sql. I am reading my SQL book and it says that your average disk should have 125 or less i/o's. And it gave the forumal but as mentioned I don't know how to find the reads and writes.

Jul 21, 2000Is there a way to get a total count of all SELECT, UPDATE, DELETE and INSERT statements to a SQL Server 6.5 database during a 12 hour period? I'm thinking maybe someone knows of a software that reads the log or monitors the server... I've been looking at the performance monitor and, although it has good information, it doesn't capture DML's.
FYI - it's for capacity planning.

Checking For Dirty Reads/writes
Apr 17, 2008
Problem Statement........
Lets say user A accesses a record and is making an update to a column... next user B accesses the same record and makes an update to the same column and saves the data... how can user A check to see if an update has been made to prevent overwriting the data..
Is there a query statement that user A can write to check for this?
I understand locking can be used to prevent this but is there an alternative to locking.

Jul 6, 2015We are in the process of moving existing clustered SQL server databases to AWS. There is one major database that has intensive reads and writes transactions. I'm wondering what is the best design to optimize the performance for both R/W since we have constant issues historically with the current environment when massive updates are happening. Reads shall have higher priority over writes.
View 2 Replies View RelatedSQL Server Admin 2014 :: Indexes With More Writes Than Reads
Jul 17, 2015I have inherited a database that is over-indexed, i.e. there are sometimes 10-20 indexes on a table. The performance is at times not great due to blocking from long running queries. I want to clean up the indexes as a starting point.
Through a query I found some time ago on the SQLCat blog I have discovered a large number of indexes in the database that have a huge disparity between reads and writes. The range of difference is sometimes almost 2 million more writes than reads. Should I just drop the indexes that have say, more than 100,000 more writes than reads and then see what the Missing Index DMVs tell me after a few days of running without those indexes?
In some cases there are a few hundred thousand reads but maybe a million writes on the index. Thus, there are a fair number of reads happening, just not in comparison to the number of writes. In some cases there are almost no reads and a million or more writes. I am obviously dropping those indexes. I just am not sure what to do about the indexes that do have a fair number of reads.
What Is The Best Way To Achieve Best Latency For Reads And Writes To SQL Server 2005?
Oct 18, 2007I am looking into various options to improve latency of our application (we figured the latency is mainly because data persistence - writes and reads from DB). I am looking into In-Memory databases also. But, before making that decision (of using in memory databases), I would like to see if there is a way to configure SQL Server 2005 to get as close performance as in-memory databases?
My question:
1. Is there a way that I can configure SQL Server 2005 to use a CACHE that gets loaded as needed basis, so that future database reads/writes will happen to the cache as opposed to disk (db writes)?
2. Is SQL Server 2005 recoverable in such configurations?
3. Are there any ideas/resources where I can get more details? (Such as sample configurations with bench mark numbers, rpevious experiences..etc)
Thanks

Writes Are Not Commited Right Away
Mar 25, 2008Hi!
First of all I want to tell you that I'm not a dba or tuning expert but I've ran a trace on a database with perfomance problems and I've found a strange thing.
The user creates orders for their service people in the organisation. I can see in the trace that inserts are done but they don't produce any writes rightaway. However after 10-15 minutes all the writes are done, what could make the actual write be delayed so much. The application is developed using .net.

Got An Expensive Server, SQL Is Very Slow On Writes
Feb 2, 2004Hi,
i am experiencing SQl write performance problems on a very shiny server. Got data files on a Raid 1+0, log files on a separate drive, all SCSI, Win2003 server, 6G RAM, 2 Xeon processors. I've created a small benchmarking program and run it on my desktop pc and this 'big' server. Here are the results:
Desktop: SQL server inserts: 78 Seconds, Direct writes to the harddisk(Just write a string to the file 10000 times): 13 seconds
SQLServer: SQL server inserts: 422 Seconds, Direct writes to the harddisk: 16 seconds
So, for some reason, my 'shiny' machine is 6 times slower on writes than my desktop. When i tried comparing the select performance, my shiny server is 10 times faster than my desktop.
Initially i had Raid5 on my server and it had poorer direct write performance but now, direct writes seem to be ok, so, i recon this is a problem related to SQL server.
What can i do to improve the insert performance?
Thanks in advance
Too Many Writes At Once Causing Time Outs?
Feb 18, 2004Hi everyone! I'm new to this forum and I suspect I'll be using this forum frequently. Good stuff.
Allow this question may appear to be Web-related, I think the problem is with what I'm doing with the database. Please read.
I'm trying to implement a page tracking solution using ASP and SQL 2000. It basically writes a new record to a table every time a user visits a page on the site. It appeared to work fine at first, then I've increasingly been getting time out errors on my pages -- all pointing to the include file that fires the database write.
Here's the code that's referenced on every page:
Set Conn = Server.CreateObject("ADODB.Connection")
Conn.Open "dsn=x;uid=y;pwd=z;"
Set objRecordset1= Server.CreateObject("ADODB.Recordset")
objRecordset1.Open "SELECT * FROM table",Conn,1,2
objRecordset1.AddNew
objRecordset1.Fi elds("PAGE") = Left(request.servervariables("SCRIPT_NAME"),100)
objReco rdset1.Fields("QUERY_STRING") = Left(request.servervariables("QUERY_STRING"),100)
objRec ordset1.Fields("DATE") = Date()
objRecordset1.Fields("TIME") = Time()
objRecordset1.Fields("PLATFORM") = Left(request.servervariables("HTTP_USER_AGENT"),100)
obj Recordset1.Fields("REFERRER") = Left(request.servervariables("HTTP_REFERER"),100)
objRec ordset1.Fields("USER_IP") = Left(request.servervariables("REMOTE_ADDR"),20)
If Request.Cookies("TEST")("ID")<>"" Then
objRecordset1.Fields("VISITOR_ID") = Request.Cookies("TEST")("ID")
End If
objRecordset1.Update
Conn.Close
Set Conn=Nothing
%>
After taking out the reference to the above code everything speeds back up. So, I know the performance hit and time out issues have to do with the code above.
Is it the simultaneous write to the table, the constant opening and closing of the recordset, the cursor type, the lock type – or combination of things?
HELP!! Thanks!

How To Make Sure No Other Table Writes Happen Between 2 SQL Statements ?
Nov 25, 2007Ok, here is my situation.....
When someone navigates to a user's profile page on my site, I present them with a slideshow of the user's photos using the AJAX slideshow extender. I obtain the querystring value in the URL (to determine which user's page I'm on) and feed that into a webservice via a context value where an array of photos is created for the slideshow. Now, in order to create the array's size, I do a COUNT of all of that specific user's photos. Then, I run another SQL statement to obtain the path of those photos in the file system. However, during the time of that first SQL query's execution (the COUNT statement) to the time of the second SQL query (getting the paths of the photos), the owner of that profile may upload or delete a photo from his profile. I understand this would be a very rare occurrence since SQL statements 1 and 2 will be executed within milliseconds of each other, but it is still possible I suppose. When this happens, when I try to populate the array, either the array will be too small or too large. I'm using SqlDataReader for this as it seems to be less memory and resource intensive than datasets, but I could be wrong since I'm a relative beginner and newbie. This is what I have in my vb file for the webservice.....Public Function GetSlides(ByVal contextKey As String) As AjaxControlToolkit.Slide() Dim dbConnection As New SqlConnection("string for the data source, etc.") Try dbConnection.Open() Dim memberId = CInt(contextKey) Dim photoCountLookupCmd As New SqlCommand _ ("SELECT COUNT(*) FROM Photo WHERE memberId = " & memberId, dbConnection) Dim thisReader As SqlDataReader = photoCountLookupCmd.ExecuteReader() Dim photoCount As Integer While (thisReader.Read()) photoCount = thisReader.GetInt32(0) End While thisReader.Close() Dim MySlides(photoCount - 1) As AjaxControlToolkit.Slide Dim photoLookupCmd As New SqlCommand _ ("SELECT fullPath FROM Photo WHERE memberId = " & memberId, dbConnection) thisReader = photoLookupCmd.ExecuteReader()
Dim i As Integer For i = 0 To 2 thisReader.Read() Dim photoUrl As String = thisReader.GetString(0) MySlides(i) = New AjaxControlToolkit.Slide(photoUrl, "", "") Next i thisReader.Close() Return MySlides Catch ex As SqlException Finally dbConnection.Close()
End Try
End FunctionI'm trying to use the most efficient method to interact with the database since I don't have unlimited hardware and there may be moderate traffic on the site. Is SqlDataReader the way to go or do I use something else? If I do use SqlDataReader, can someone show me how I can run those 2 SQL statements in best practice? Would I have to somehow lock writing to that table when I start the first SQL statement, then release the lock after I execute the second SQL statement? What's the best practice in this kind of scenario.
Thanks in advance.

Apr 18, 2002I upgraded from 6.5 to 7.0 SP3. Now when I save (write) an invoice it takes about 10-12 seconds, at 6.5 it was 1-3 seconds. SQL Server and my Materials App are the only thing running on this box. This is the only area that has gotten slower everything else works great. I have 3 users saving invoices and about 15 people total using the system at one time. It's a compaq DL580 loaded with memory, database is 2,195MB in size. Same 6.5 client to access system as before. Should I rebuild/reindex the database? Is there something from the old 6.5 version I need to remove?? Thanks in advance!!!

My Error Handler Writes Duplicate Messages To Email!
Aug 22, 2007I am using an error handler that was provided to me from another source. However, I notice that there's something in the code that writes the error message twice. I tried to discover what it was, but could not seem to pinpoint it. Here's an example of what my email messages look like:
Is activity file current?
The Script returned a failure result.
The extracts in D:myFolder are not current! Data NOT loaded.
Is activity file current?
The Script returned a failure result.
The extracts in D:myFolder are not current! Data NOT loaded.
Obviously, I just want my email to read:
Is activity file current?
The Script returned a failure result.
The extracts in D:myFolder are not current! Data NOT loaded.
Somewhere, errorMessages is being written to more than once. Need help finding the error.
Thanks!

OnError event:
Public Sub Main()
Dim messages As Collections.ArrayList
Try
messages = CType(Dts.Variables("errorMessages").Value, Collections.ArrayList)
Catch ex As Exception

Mar 25, 2008Hi!
I was assigned to solve performance problems for an application. I fired up Sql Server profiler and started a trace. Downloaded Sql Server Trace Analyzer. It's a trial version so it's very limited. What I found is that one stored procedure generates almost 400 000 reads everytime it's used and it's used everytime the user wants to see his orders. I've tried to translate the t-sql to english from swedish, it looks something like this:
select top 100
o.orderid,
o.name,
o.latestdeldate,
os.name as OrderStatus,
os.orderstatusID,
p.placeID,
p.name as place,
p.address,
p.city,
a.name as worktype,
noOfActions=(select count(*) from actions a where a.order_orderid=o.orderid),
noOfServiceObjects = (select count(*) from Serviceobject s, Actions a where s.Place_PlaceID = o.Place_PlaceID and a.order_orderid = o.orderid and a.Serviceobject_serviceobjectid = s.serviceobjectid),
...
...
...
It has 8 select count(*) in the select statement then in the where statement it has 2 more select count(*).
I know it's very difficult for you to come up with a solution but do you know a better way than to use select count(*) everywhere? The count is used for to show different status flags on the website.

SQL Server Admin 2014 :: Backing Up To Mount Point - Perfmon Shows Zero Writes
Apr 20, 2015Im backing up to a network directory thats actually a mount point on a different server.My backup was slower than usual so i opened up perfmon to have a look.
When selecting the mount point from the Logical Disks section in perfmon i can see that writes/sec & write bytes/sec both show zero for a long period of time, even though the backup percent complete is increasing.Then all of a sudden the writes to the network share jump massively.
Is there some caching mechanism for backups in sql where during a backup data is only flushed to the disk periodically during backup?

More Reads Then Expected
Jul 18, 2006So I€™m at a dead-end looking for the reason behind the following behavior. Just to make sure no one misses it, the 'behavior' is the difference in the number of reads between using sp_executesql and not.
The following statements are executed against a SQL 2000 database that contains >1,000,000 records in the act_item table. They are run using Query Analyzer and the Duration and Reads come from SQL Profiler
SQL 1:
exec sp_executesql N'update act_item set Priority = @Priority where activity_code = @activity_code', N'@activity_code nvarchar(40),@Priority int', @activity_code = N'46DF335F-68F7-493F-B55E-5F9BC6CEBC69', @Priority = 0
Reads: ~22000
Duraction: 250-350 ms
SQL 2:
DECLARE @Priority int
DECLARE @Activity_Code char(36)
SET @Priority = 0
SET @Activity_Code = '46DF335F-68F7-493F-B55E-5F9BC6CEBC69'
update act_item set Priority = @Priority where activity_code = @activity_code
Reads: ~160
Duration: 0 ms
Random information:
Activity_code is an indexed field on the table, although it is not the primary key. There are a total of four indexes on the table, none of which include the priority as one of the fields.
There are two triggers on the table, neither of which is executed for this SQL statement (there is an IF UPDATE(fieldname) surrounding the code in the trigger)
There are no foreign relationships
I checked (using perfmon) to see if a compilation/recompilation was happening. No it's not.
Any suggestions as to avenues that could be examined would be appreciated.

SQL Server Admin 2014 :: How Data Writes In Multiple Secondary Files If There Is No Filegroup Created
Nov 12, 2014I read , When sql server Database having multiple data files within single filegroup then sql server writes data in multiple proportional file algorithm where the amount of data written to a file is proportionate to the amount of free space in that file, compared to other files in the filegroup.
so if there is no filegroups created and multiple secondary files are attached in databse , is there same way data stored and writes data in multiple files by the same algorithm or any different way.

Log Reads In SQL Server 2005
May 31, 2006I have a set of triggers that log the history of changes to a table - i.e. I record inserts, updates, deletes (pretty standard audit stuff I suppose). I want to also log reads on that data. If I were using sprocs for reading data, this would be relatively painless, but I am using an O/R mapper to handle my data access, which writes dynamic sql at runtime (and I don't want to use sprocs with it) and then sends it down to the DB. Is there a way I can intercept reads and log them to the same table I am logging other actions? I know very little about the new capabilities of SQL Server 2005, but I would think I could somehow, maybe via the new CLR capabilities or similar, get access to these types of events within the database? Anyone? I know I could always do this higher up in the application layers, but I would like to keep all of this at the database level if possible....Thanks,

First I created a unique clustered index and the reads shows (3258445), then I created a non clustered index expecting to have lower reads. Instead the reads shows (10253548).
I read creating indexes helps reduce reads. But it's not happening.

Number Of Reads In Profiler
Jul 27, 2007Hi,
Can any of can explain, what the "Reads" column in Profiler exactly mean ? I'm not comfortable with the explanation given in BOL.
"The number of read operations on the logical disk that are performed by the server on behalf of the event. These read operations include all reads from tables and buffers during the statement's execution"
For the same procedure with same parameters, if the server is not loaded much, the Reads are in a few hundreds, but when there are more than 1000 concurrent users, why it is going to millions ? What other parameters affecting this reads ? And how can I reduce it ?
Environment: SQL Server 2005 64-bit Enterprise Edition on Windows Server 2003 R2 Server x64 Enterprise Edition SP2

Transaction Lockout Of Reads
Aug 28, 2006Hi,
I have been seeing a basic scenario of a write transaction appearing to unexpectedly lock-out reading.
The database has isolation set to "READ COMMITTED".
The scenario is:
1.) Start a transaction (for doing a write)
2.) Do a read before the transaction (for doing the write) is committed (e.g. sqlCommand2.ExecuteReader()).
--> the code will appear to lock-up (then time out).
I see the same behavior if I step through the "write" code with the debugger (to a point after the transaction is started, but before it is committed), and run a "SELECT * FROM" type query from Microsoft SqlServer Management Studio.
Following is the code sample demonstates the issue.
Thoughts on how to resolve the issue (to let me do "read committed" reading of the database table)?
Thanks!
