Dear All,
Finally I completed my project. Thanks all you helped me to do it.
Now I have the biggest problem.
In my application the Data grid is filled with Data from SQL server table which has large number of records. When I run my queries in SS Management Studio it runs very fast. To fill data to datagrid it takes lots of time. How can I reduce this time. How can I increase the performance of my Application.
Thanks,
Janaka
Dear all viewer ,
Thanks to everyone.
We are using -
MSSQL Server 2000 on windows 2000 advanced server.
PB 7.0 for client server front end tools.
Prior to few days our application works fine, rightnow it get slow or not responding after few (4/5) transaction. We don't know wht it is, If anyone has same experience so that is helpfull for us.
Thanks

We are having issues w/ a stored proc call in our application. When I run the proc through a query window in Mgmt Studio, it comes back in .3 seconds. However, when the application runs the proc (w/ the same parameters), it takes 30 seconds for the proc to complete. When I run a trace with the proc call through Mgmt Studio, it says 4000 read, but through the app, it says 4 million reads. What is happening?? (app uses Hibernate 3.2/ Java 1.5/ JDBC)
Thanks.
Hi,
We are having SQL2000 Advance Server.
4 processor with hypherthreading, Memory 4 GB and it is a high transactional OLTP server. We are also running Transaction Replication on that server.
We recently bought Double Take and implemented on the server with File Difference with block check sum option for Disaster Recovery Purpose.
The Queue and the Log file folder is on local drive where the system doesn't use that folder except double take.
We are replicating from Source to Taget thru the WAN (DS3).We are replicating approx. 200 Gig of Data but just the difference.
Now the CPU usage is normal,Memory utilization is normal, but the network is a major problem as the Applications connecting to the Server timesout and the applications running very slow.
We have set just like the Tech support recommended.
I would appreciate, if someone give us some recommendations to run the double take without any problem.
Thanks in advance.

Hi,
Recently our database has been migrated from SQL 2000 to SQL 2005 on a new server(machine) with windows 2003(previously windows 2000). If the database is retained on the same machine but with a named instance of 2005, the application(websphere 5.1) is behaving normal whereas if i configure the aplication to the new server it is running slow for some of the queries but not all.
This change will have to be implemented in production very soon. Any advise will be of great benefit
Thanks

Hi,
first time poster/newbie here.
I've
got a football (soccer for the yanks!) predictions league website that
is driven by and Access database. It basically calculates points
scored for a user getting certain predictions correct. This is the URL:
http://www.pool-predictions.co.uk/home/index.asp
There
are two sections of the site however that have almost ground to halt
now that more users have registered throught the season. The players
section and league table section have gone progressively slower to load
throughout the year and almost taking 2 minutes to load.
http://www.pool-predictions.co.uk/home/players.asp?tab=a_d
http://www.pool-predictions.co.uk/home/table.asp
All
the calculations are performed in the Access database Ive written and
there are Access SQL queries to get the data out.
My
question is, is how can I speed the bloody thing up! ! Somone has
alos suggested to me that I use stored procedures and SQL Server to
speed things up? Ive never used SQL Server before so I am bit scared
about using it (Im only a hobbyist), and I dont even know what a SP is
or does. How easy will it be upgrading the whole thing to SQL Server
and will it be worth the hassle, bearing in mind I expect my userbase
to keep growing? Do SP help speed things up significantly? Would
appreciate some advice!
Thanks in advance,
John.
Hi,
I'm developing a desktop application using CAB and DevExpress 6.3 controls. I use ReportViewer control to render .rdlc reports under local mode.
I loaded data source from a dataset, template definition from a string, called the Refresh method of ReportViewer.LocalReport, so far, all are OK. But once I call the RefreshReport method of ReportViewer, the whole Application slows down, even after I closed the report viewer form. Operations like switch between menu items, open a new form and resize the main form become double or triple slow, CPU usage is keeping in 100% while doing those operations... I've no clue how refreshing report affects all those UI drawing...
However, if I break down and jump over the RefreshReport method, an empty report form shows and every thing keeps OK.
After all, all the reports can be rendered and shown correctly finally...
And seems there is nothing to do with the templates and data source, the templates are very simple, and event if I render the reports with empty data tables, it also slows down my application.
I tried to create and run the form in a new thread, tried to upgrade to ReportViewer 9.0, but both seem useless.
Could any body help me on this problem?
Thanks in advance.
Hello All,
I’m looking for a solution to timeouts that occur when I’m executing a stored procedure from my web application. Most of the SPs will run from 3 to 15 minutes, and, unfortunately, modifying/optimizing them isn’t an option at the moment. I tried setting the CommandTimeout to 0 with no luck. Unless, I didn’t use it properly. Here’s my code: 1
2 try
3 {
4 string dbConn = ConfigurationManager.ConnectionStrings["ConStringNTMTLDEV"].ToString();
5 OleDbConnection connection = new OleDbConnection(dbConn);
6
7 lbl_SearchResult.Text = dbConn;
8
9 //OleDbDataAdapter adapter = new OleDbDataAdapter();
10 OleDbCommand cmd = new OleDbCommand("SP_CallHistoryLookUp", connection);
11 cmd.CommandType = CommandType.StoredProcedure;
12
13 cmd.Parameters.Add(new OleDbParameter("@phoneNumber", "1234567890"));
14 cmd.Parameters.Add(new OleDbParameter("@email", "123@123.com"));
15 cmd.Parameters.Add(new OleDbParameter("@WebUser", "123"));
16 connection.Open();
17 cmd.CommandTimeout = 0;
18 cmd.ExecuteNonQuery();
19 cmd.Dispose();
20 connection.Close();
21 }catch(OleDbException ex)
22 {
23 lbl_SearchResult.Text += "<br/> Something went wrong </br>";
24 lbl_SearchResult.Text += ex.Message.ToString();
25 }

Is it possible to launch a stored procedure and close the connection without waiting for a result?Would the stored procedure still run on the SQL server? I’m using MSSQL 7. Would you have any examples that would solve this problem? Thank you for your help.

I made an application with VS 2005 that connecting to sql server file db.mdf
Now i want this application work on another user computer, and of course i don't want to install vs 2005 there.
I did install .net framework, but what i need to do to make the database work? do i have to install sql server on his computer? or is there something more simple?
I know that if i was using access file than i need to install nothing else.
please help!
thanx.

I am writing a data access web page, but I find that the excution speed is too slow.
My data base is just a data table which have five columns: id, code, quantity, price and Date. The data base has about 45000 rows. When I use OSQL or Query function, speed is just fine.
Here is the main code which I think cause the speed slow:
string conn = ConfigurationSettings.AppSettings["connectionstring"];
SqlDataAdapter adapter_2 = new SqlDataAdapter("select * from table",conn);
DataSet ds = new DataSet();
adapter_2.Fill (ds,"table");
DataTable YahooOrders = ds.Tables["YahooOrders"];
DataRow[] product = new DataRow[20000];
.......
foreach (string s in split) // actually the split here has only one string in it
{
product = table.Select ("code like '"+s+"%' and Date >='"+minDate+"' and Date <='"+table.Select("Date = Max(Date)")[0][1].ToString()+"'");
foreach(DataRow myRow in product)
{
int count = Convert.ToInt32(myRow[2]);
itemQuantity = count + itemQuantity;
revenue = Convert.ToDouble(myRow[3]) * count + revenue;
// get product code, ignore repeated code
int myIndex=code.BinarySearch( myRow[1] );
if ( myIndex < 0 )
code.Add(myRow[1]);
}
orderQuantity = product.Length + orderQuantity;
}
The first foreach actually excutes just one time, so it won' t cause any speed problem.
The second foreach' s job is to sum each column of specified rows which is product here.
So, any ideas about this?
Thanks!
All,
Actually from the application the developers are using count(column) to know the no. of rows resulted by a statement which joins many tables but its taking lot of time.
Is there an easy way to get the count of records(result set) of the output.
I cant use sysindexes b'z i need the count of the output genereted by the SQl Statement which joins many tables and retrieves many rows.
Thanks,
Sajai
Hi fellas (and girllas),
Got a problem (duh!). My MSSQL Server lags. Now, mind, it doesn't lag all the time. And it seems to be independent of the # of users trying to access the server. And it random clears itself up. And the problem doesn't present itself in SQL MGR, just on the web app we're running on it.
Setup:
SQL Server 2k running on 2k3 w/ IIS & backup exec.
All SQL data files are on a raid5 SCSI U160.
App:
Intranet App developed by us for us. ASP.NET & VB.NET.
Symptoms:
When queried server takes a LONG time to respond. So long infact it has become counter productive. When taking a look at the server, the CPU usage hovers between 50-75% and spikes up to 90% every now and then just for kicks. The memory usage is 2.35gb out of 4gb. To fix this we have to kill and restart all the SQL services.
Any thoughts on what to look at? There're indexes on the required FKs and the heavily queried columns. We're at a loss here.
Thanks for any helpful help!

Database has its few HUGE tables, but I experienced queries against few other very small tables to be incredible slow.
Anybody has the same or similar problem?
A vendor's application is performing slow. Vendor tested it in QA and it's slow. End-users run it in PRD and it's slow. The application calls SP1, and SP1 calls SP2. Inside SP1 has a cursor. I believe as the db gets larger. The application is going to be even slower. What can I suggest to the vendor in order to fix it? Tell them to re-write the application code? Eliminate cursor?
Thanks

There re certian times when I want to execute a sql request (select for example) then It gets too long before I get an answer. (that happens only some times exceptionnaly). What does that mean, is it that somebody is using heavily the DB or may be using Entreprise manager or what exactly
and how can I know who is responsible for taking all SQL server resources at that specefic time. What command or what tool can I use pls for this purpose.
Thanks for your help.
Hello,Were using the data transfermation service to copy in an Ingres II 2.5database to an SQL Server 2000 database. Small databases don't present anissue, but when pulling one across that's about 20GB its been taking between12 and 24 hours. Both systems are relitively quick boxes and neither of themare tapped out on processor, disk I/O or network resources.I do have the "Boost SQL Server priority on Windows" checked under it'sproperties and all the processors are checked to be used.Does anyone know if there's a way to tweak SQL Server or Ingres to handlethis a little quicker? Or even an idea where the bottleneck could be may behelpful.Thanks,John.
View 1 Replies View RelatedI've got a performance question about a clr tvf that I have created. When I query the function it takes about 30 seconds for it to execute as apposed to < 6 seconds when I execute the same code in a console app (the 6 seconds includes outputting the returned data to the console, without writing the output to console it executes in about 1 second). Both the function and the app are iterating (>40,000) and returning ( >10,000) the same number of rows. I've noticed the following when viewing the executions in the PerfMon:
* the sqlclr tfv kicks the % Processor Time up to 30 for 30 seconds, the console app has % Processor Time at 9 for about 2 seconds
* .NET CLR Memory - Allocated Bytes/sec spikes anywhere from 1 to 3 times during the sqlclr query at about 44MB/sec. It barely registers if at all when the console app runs.
* In either case, % Time in GC is at zero.
I'm assuming that there are some configurations I'm ignorant of that can help me tune the execution. I can't imagine that it takes SqlServer that long just to iterate through the records.
I have recently decided to make the change from Microsoft access to SQL Server believing that it's a bigger faster beast with better parameterized queries and triggers and all that. BUT.I have some client data that I imported from their original paradox files.The invoice lineitem file contains over 1 milliion records.When I open this table in access and click show last record, the record is displayed in about 1 or 2 seconds.I used the upsize to SQL Server tool in Access to shift my data into SQL Server.When I use the Express Mangagement tool to open the same table and say show me the last record, it takes 17 minutes.I admit that most numeric data types have been translated to floats, so that's probably not good.But I cant alter them from floats to numeric or decimals using the table design tool.Do the conversion anomalies make up the whole reason why SQL Server seems so incredibly SLOW! ?????????
View 2 Replies View RelatedI am running the following BCP to extract a table with 156641604 rows.

When running this i notice that the disk read bytessec counter in performance monitor on the drive that has the database devices is only reading 30mbsec. I am writing the bcp file to a different drive. Both drives are far more capable of achieving much higher IO. Is this a limitation with BCP or are there futher switches available that would speed this process up. Also the drives are both local so the bottle neck is not network. Any ideas?
Has anyone else noticed delays with SQL Express? I'm not really talking about delays on the queries but just delays in general response. For example: everything is running great, then for about 2 minutes I get connection timeouts etc can't even open stuff in the management studio without getting timeouts ... then as strangely as it started everything goes back to normal and requests are served again.
The server has nothing on except 1 website, its Win 2003 Server. 512MB Ram on a PIV. The memory usage is low and during the "lockups" the machine isn't showing any processor usage and SQL mem usage is around 40Megs.
I am not using User Instances either. Nothing in the event logs. What is odd, is its happening on 3 of my machines ..... all with different sites, the only thing in common between them is SQL.

This sounds like a pretty easy one. I have a SQL 2000 database with 2-3.4GHZ CPUs and 1GB of RAM. I have one database on it. I go in Query Analyzer on another machine and run a simple query like 'SELECT * FROM USERS' which should return 15,000 rows.
IT takes 30 (thirty) seconds to finish this query. OMG
Where do I start to decipher why on Earth this takes more than .01 seconds?
Thanks.
Hi all...

Hello,
We have Sql Server installed on the Windows 2000 machine.
There are 2 databases that the employees access on it.
When the machine is just started, there are no problems but after some time the connections get really really slow and then eventually become impossible to connect. We did not have this problem before until we had a computer crash and then Sql server was installed on a new machine. The problems started here. We had 64mb of ram and we put in another 64mb thinking this would solve it but it did not.
On the task manager the cpu percentage stays constant at 100% and the virtual memory increases and increases very slowly until it has reached it's maximum (which is 600mb).
Any information would be greatly appreciated.
Thanks very much,
Kostas
Hi,
I have a query which has suddenly started responding slow.

Hi,
Some of my queries are running too slow.It's taking as long as 30secs .Earlier the same query was taking less than 5 secs.
I understand the db has grown BUT I do not know to look at this query where should i start from and what should I look into.
It is on production server.
the db size is 15GB and unallocated is 9GB.
log space used is 4%.
TIA.
After I installed SP3 on a production SQL box, backups are a lot slower. Anybody have any suggestions?
Thanks in advance

I am configuring a new Server running SQL Server 7.0 sp2.
I have a job that runs a large process. From the SQL Agent job, the processing time is over 8 hours. If I run the same process from a query window, it takes an hour and a half. On my 6.5 database, the job takes 2 - 3 hours from the scheduled task. What is going on with SQL Agent? I have not been able to find any information on memory and SQL Agent.
Any help would be greatly appreciated!

I have a dts job set up to transfer 550,000 records from a dbf file into a sql server. If I just let it run, there is a 9-10 minute delay, then it starts. If I try to schedule a job, it fails completely. I looked up ways to get it to execute quicker, mainly going to the advanced tab of the transform arrow and making the inserts 1000 at a time, the table locked, turning constraints off. Any advice on how to speed it up or why the job is failing?
