Newbie: Slow Response Time Querying Systemjobhistory
Apr 29, 2008
Hi,
I have a problem with querying systemjobhistory data. Response time is slow and it is vary from time to time, sometime it takes few seconds and sometime it takes more than 2 minutes. I understand that there is quite a number of jobs in DB server and which might result in slow response time.
Is it possible to shorten the response time? like using index? My application is always look like hang when the query take very long time to run.
Hi I have Problem, My response time is too Low. Is Any one Know how to improve my response time. My DATABASE SIZE IS 11 GB. I didn’t change any configuration parameter after installing SQL Server. Right my server Having default configuration parameters. Whether I have to change any parameters or not. My queries will generate lot of temporary tables.
We did an in place convertion of our data base from MS SQL Server 6.5 to 7.0. Our application is much slower now on SQL 7.0. Any idea why? The following is a sample SQL statement that runs quickly on SQL 6.5 and takes a long time on SQL 7.0 I also attached the query plans from SQL 6.5 and 7.0.
SELECT Person_Name.PerNam_Person_Name_PK , Person_Name.PerNam_Row_Status , Person_Name.PerNam_Last_Name_Sndx , Person_Name.PerNam_Last_Name , Person_Name.PerNam_Name_Suffix , Person_Name.PerNam_First_Name , Person_Name.PerNam_Name_Prefix , Person_Name.PerNam_Middle_Name , Person_Name.PerNam_Event_Person_FK , Event.Evn_Event_Nbr , Event.Evn_Event_Type , Event_Person.EvnPer_Last_Name , Event_Person.EvnPer_First_Name , Event_Person.EvnPer_Middle_Name , Event_Person.EvnPer_Name_Prefix , Event_Person.EvnPer_Name_Suffix FROM Person_Name , Event , Event_Person WHERE (Person_Name.PerNam_Agency_ID = "CL") AND ( Person_Name.PerNam_Event_Person_FK = Event_Person.EvnPer_Event_Person_PK ) and ( Event_Person.EvnPer_Event_FK = Event.Evn_Event_PK ) and (Person_Name.PerNam_Person_Name_PK = 0 or ( Person_Name.PerNam_Event_Person_FK = 581541) ) and ( Person_Name.PerNam_Row_Status <> "D" )
Query plan in SQL 6.5

Using SSMS 2012, we are experiencing extremely slow response times when opening SQL job steps to edit and also deploying SSIS Pkg's. Sysadmins have no problem. Users in the ssis_admin role have no problem. It's the rest of the users who have issues.
At my location we are running Great Plains on SQL server with the Great Plains client on the front end communicating over IP Sockets. Occasionally the client will stop responding for up to 15 minutes. This occurs to all clients at the same time. While this is happening I have ran performance monitor on the SQL server using the SQL counters and everything looks fine. Performance on the server and the network does not degrade. Only the Great Plains client is affected. From this I feel this is not a network problem. I would like some suggestions on what could possible cause this type of problem. I am really just looking for a starting point on where the problem may be originating from. Any suggestions will be greatly appreciated.
Here is the configuration we have at our site: 64 bit virtual server - Clustered 64-bit SQL Server 2005 Standard SP2 listening on port 1433.
32 bit virtual server - 32-bit application that connects to above SQL Server 2005 via standard OLEDB driver installed with windows (String utilized: Provider=SQLOLEDB.1;Persist Security Info=False;Initial Catalog=applicationdb;Data Source=ServerInstanceName).
We are experiencing a slow reponse of 45 sec to more than a minute on a simple select statement on a table having 5000 rows.
The same select statement on the Server locally in Studio returns results back in 2 seconds or less. But from Stuido on any other desktop (remote) it takes 45 secs or more. Same slow response is seen by the application which is using OLEDB.
I've looked into some of the Server parameters but didn't find any clues.
I ran into a situation that if I don't use sql server for a while, in MS SQL Server Management Studio, when I run some query again, it takes a long time to respond. I looked into it with Activity Monitor, seems like the query was waiting for something, in the process view tab, it shows that: WaitType: LATCH_EX Resource: LOG_MANAGER(112F88C8) What is the latch-ex? What should I check next to find out the problem?
Hi all, I have a website www.searchcontracts.com which has a search feature on the front page. The problem is that whenever a search is submitted (without and filters) it processes extremely slow (if at all, sometime throws 'general network' errors). If working properly it will return about 500+ records. As far as i know if there should be no issues returning a recordset of this size. I have the site hosted in a shared environment and it uses a SQL2000 db. If you filter the search resutls, it's more reponsive (still fairly slow). If you believe that the hosting server i'm using should be upgraded, what would be the best solution? Keep in mind that i want to be able to return way more than 500+ records in one go. Thanks Jakehttp://www.searchcontracts.comhttp://www.custommethod.comhttp://www.boozetour.com
I am working with a client that after every reboot of there SQL 2000 DB server, they experience slow response time for a couple of hours. The server has 12 GB RAM and a Dual 3.8 processor. It is believed that the slow response is due to as queries run after the reboot, they are re-building information in memory and after the memory is built up, it goes back to the normal performance utilizing the memory for speed. Is this an accurate assumption or is there something else to be looking at after the server is rebooted?
I have 2 servers (say MAINSRV e SECSRV) running SQL2000 Standard SP3 on Windows 2000 Advanced within a NT (!) domain and each server is linked to the other.
My problem is that if I run a query returning few dozens of rows like:
SELECT * FROM MAINSRV.DbName.dbo.TblName TBLA WHERE Fieldx = 'anyval'
from a client connected to the SECSRV server, it takes something like 35 minutes to complete, while the same query completes in no time when run on clients connected to MAINSRV.
Even the simplest SELECT Count(*) FROM... takes more than one minute from SECSRV while completing in a fraction of second from MAINSRV.
I tried to change the linked server security options (SQL/Windows), but the remote query remains slow.
There are no locks active on the table, both the servers have almost no load (CPU less than 10%, when tested) and the query returns just a few KBytes, so communication overhead will not be the problem.
Any suggestions will be very appreciated, thank you!!!
Hello.I have a slow response with a system that I am setting up. The OS isWin 2000 Server with SQL Server 2000. My first execution of the SQLprocedure is slow (about 40 seconds), while the second execution isfaster (approx. 3 seconds and what I expect).Using query analyser I can leave the window up and come back ( aftersay 10 minutes ) and my next response is will be slow (and fasterstraight after this).The query itself is the "TOP 10" rows from a table of a remote DB (MSDE2000 - NT station).This is similar to;---------------------DECLARE @SelectRowsFromRemoteDB NVARCHAR(400)SET @SelectRowsFromRemoteDB = "SELCT a.* FROM OPENROWSET('SQLOLEDB', 'Remote', ....) a"EXEC sp_executesql @SelectRowsFromRemoteDB---------------------The CPU usage goes high (with Task Manager), but oddly the task withmost usage is the "Idle Process".Please help with an answeror a good starting point to known where the resources are being used.Regards JC.....
When I launch Outlook, it takes forever for the program to finally open. With any inbound email, it stops processing whatever is underway at the time....and frequently there is a 2-3 second lag between keyboard input and what appears on the screen. SQLserver is usually consuming upwards of 1-gb of memory....help. Mike
Regarding SSRS, what is considered a good response time? We have some reports running 2 minutes and the users think that is too long. Is there a guideline as to what a user should reasonably expect and if so, what is that guideline?
When I try to connect to a SQL server instance from Enterprise Manager, I'm getting a timout connection error. I have to change the timoeout parameter from 4 (the default) to 30 in order to work. Also I realize that some applications (like sharepoint) are having the same problem connecting to that server.
My question is:
Why is that happening?
It used to work fine, and I'm getting this issue a couple of days ago.
I am currently migrating a DB from Oracle to SQL Server (Microsoft SQL Server 2005 - 9.00.1399.06 (Intel X86))
I've used ssma to do the migration, and I'm reviewing the prodedures to check them. I have find a performance problem in one of them, which worked perfectly under Oracle, and I have tried lots of things with no luck, so I guess I need some help
I insert a row in a table, and the time it takes for this is fine, but seconds later I need to read the row, and this Select lasts 1-2 ms more every time. This process is repeated lots of times.
Every insert-select takes 200 ms when it receives the first data (including some other operations that are not increasing the response time), and 200 insertions later it takes about 500 ms, which is really too much, considering it keeps increasing.
The table has 25+ columns, and some of them contain varchar of 3000+ characters.
I make the select using 4 columns in the where part. One of them is a numeric, and the rest are varchar (no one is the primary key).
I've got a clustered index for the primary key, and two more non-clustered indexes. One of them refers to the columns I use in the Select, and the parameters are Fill Factor: 90, and Recompute Statistics Automatically.
Is there a global variable or something of the sort that would tell me how long it took to execute a query??
I need to monitor my DB response times and we have a query that runs in under 2 seconds. So we want to run this query every couple of minutes and if it takes more than 12 sec to run, we want to send an email to our DB staff...
I know that I could take a time stamp before and after then subtract but I wanted to know if there was an easier way to do it..
We have poor performance spikes on a drive containing our log file but this is only for reads and seems to be at a time when we run a re-index job. If this is a likely correlation as to poor performance in reading the log file, and what reads are done from a log file.
I have a procedure that calls a SVF to convert an xmldocument. The ultimate purpose is to update the xml in a column in a multi-million row table. The xml is stored as varchar(MAX), it was supposed to carry any type of text, initially at least.
My question is: why is the xml-parsing performed inside the function much slower when i pass the xmldocument as type xml than when it is passed as varchar(MAX) and the CAST to xml is within the function? Does processing the xml input parameter in SlowFunction involve expensive crossing of some context border?
The two versions of the SVF (they return the rowcount in this simplified example):
CREATE FUNCTION [dbo].[FastFunction] ( @inDetaljerText varchar(MAX) ) RETURNS int
[Code] ....
The two versions of the SP
CREATE PROCEDURE [dbo].[FastProcedure] AS BEGIN SET NOCOUNT ON; select dbo.FastFunction(al.Detaljer)
Creating a web application. Running a simple query "SELECT username FROM vwCustomer"
vwCustomer is a view built on top of an Access DB which is set up as a linked server. Within SQL Server that view responds immediately. But when I try to access it from an ASP page it takes over 20 seconds to respond.
I have a stored procedure which creates 3 temporary tables. Every table is about ten rows and 25 columns. The inserts in the tables goes fast (< 30 ms). The selects from them is also that fast. BUT the first select takes about 3200 ms one each of the temptables. (I first do insert, then select from them.) So the SP executes at about 13 seconds instead of 3.
We have an application that has about 100 users at a time. Roughly once a day, we experience a complete slowdown on the server. All users notice it. The network seems fine because I can ping the server. Also, I can attach to drives on the server quite fast so I don`t think it`s server resources. When I manage to get in and do an sp_who, certain processes are blocking others. Talking to the users who were blocking, they were not doing anything out of the ordinary - one was even doing just a select. The error log is full of 17824 and 1608 errors. Is there some configuration setting that I should change? This is getting serious!
Hi, I have a query which returns normally in less than a couple of seconds. When coupled with a "TOP" statement however, the execution time changes in a way I can't explain.
When using "TOP 1000", the query returns in its normal time. Any top value greater than 10 seems to function normally. However, as soon as we hit this "magic number" the query begins taking 30+ seconds to return.
As far as we can see, there is nothing odd about this query or the data that it is searching, and this problem has us stumped! Can anyone explain why top is producing these results, and is there any optomisation changes that anyone can suggest to give us faster queries in these cases?
I've noticed that after the database have been idle for some time, it takes up to 10 seconds to get it started when something needs to access it. In the event viewer it says that the database <name> have been started.
Obviously, there is some idle timeout setting.
I saw an option in the database properties that is called "Auto Close" which is set to true. I assume this is what i'm looking for. Can someone confirm that? (it could take some time to test myself...)
But what i'm actually wondering is:
1. Is it possible to adjust how long it would wait before timing out? 2. What advantages does closing the database bring? Does it free up (a noticeable amount of) ressources? Or is it only that it's unlocking the files, so that it's possible to copy the database source files?
The following question might sound a bit stupid but I'm not a database expert so hopefully nobody minds me asking it.
Here's what I did:
1. I created an SSIS package that is supposed to import new data into my data warehouse as it becomes available.
2. Since I need to maintain some of the history I use the Slow Moving Dimensions part (set the history flag on input fields) but run into an error condition while running the package. The message basically says that I'm about to create a duplicate record which is not allowed.
Now on some records the package is supposed to archive history by populating the (new) fields. In order to keep the record unique (primary key constraint) thought, do I need to make the (new) fields primary keys as well?
So I guess I'm struggling with a more basic concept;)
I would appreciate if somebody could shed some light on this.
The SSRS website is slow when accessing it the first time after a period of inactivity (30 min. or longer). What could be causing this and how can I make it fast all the time.
I am running SQL 2005 reporting services on a windows 2003 machine with SharePoint over SSL
My reporting services web directories are virtual directories under the SharePoint website.
I am having a problem with loading https://sharepoint.mysite.com/Reports/Pages/Folder.aspx
When you first open IE and bring up the page it takes about 30 seconds to load. Once you have connected via any machine, all other machines can connect at normal speed 1-2 seconds. All testing is being done on our LAN so there is no bandwidth issues when opening the pages.
My guess is that something is going into a sleep mode, but I am not sure where that would be set.
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 } 26 27 28 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. R.
when i execute a query for the first time whith full text service from visual studio, show me the error 'server not responding' and when i execute this query for second time works perfectly.
Hi there I sorry if I have placed this query in the wrong place. I'm getting to grips with ASP.net 2, slowly but surely! When i try to access my site which uses a Sql Server 2005 express DB i am receiving the following error:
Server Error in '/jarebu/site1' Application.

The database is definitly in the folder that the error message relates to. What I'm finding confusing is that the connection string seems to be finding "aranga"s database. Is it something daft?
Every so often I am seeing this error in the Event Viewer on Windows 2003 Server. It related to a file that pulls documents from a SQL server db using Response.BinaryWrite. When it pulls a file of about 2MB it creates a warning in the EventViewer. I was told to look at using Response.WriteFile to pull the file instead. I found this page: http://support.microsoft.com/kb/306654 which talks about it but doesnt give an explination on how to integrate with grabbing the content. Does anyone know how to pull db content and use WriteFile and put the file into the Response. Similar to this: Response.Buffer = TrueResponse.Clear()Response.ContentType = contentTypeResponse.AddHeader("content-disposition", "attachment; filename=" + fileName)Response.BinaryWrite(content)Response.Flush()Response.End()
