SQL Server Response Time
Nov 21, 2007
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.
Appreciate your help.

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?

Hello,
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.
I hope I explained properly...
Any ideas?

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 ,

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..
Thanks.

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.

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.

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.
Any help is greatly appreciated. Thank you.

Hi,
I have a problem using service broker, a send the message from server SSB1(initiator) and a receive this message on server SSB2(target), but I don't receive response to SSB1...
In my server SSB2 has this messages on Profiler:
- This message could not be delivered because it is a duplicate.
- Could not forward the message because forwarding is disabled in this SQL Server instance.
- The message could not be delivered because it could not be classified. Enable broker message classification trace to see the reason for the failure.
Message from SSB1 Profiler:
- This message was dropped because it could not be dispatched on time. State: 1
And the messages not end in both servers

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?
Thanks,
JB

Hello,
I need to know if I am able to use OLE DB connection strings without the username and password for Challenge/Response logins.
I have a web site that uses SSL and Challenge/Response to authenticate users, but my connection to the database is by embedding a generic username and password in the connection string.
I would like to leave that off and have the connection to the database use the challenge/response authentication when they first logged into the web site. This way I can control their permissions in SQL server.
I appreciate any help

Hello,
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!!!

I have recently installed SQL 2005 client tools with SQL Server Management Studio and accessing databases on a SQL 2000 server. The response I am getting is extremely slow. Should I go back to SQL 2000 client or are there methods by which I can improve the performance.
Thanks

Hi,
I have two servers, one production server and one backup server which have transactional replication with a pull subscription.
When I configure replication, it works fine during our test weekends testing production load. After tests, replication looks fine for a random number of days. Then, all of a sudden, an error message is displayed on one of the agents: "The agent is suspect, no response within 10 minutes." This has happened a number o times. If I remove replication and configures it again, it always works. Sometimes it works by just updating one of the tables and the error message disappears. The last time (today) that did not work. Updating the database did not replicate and the error message remained.
Has anyone experienced this same problem and has a god solution. One thing that is common is that the error message appears after long times of inactivity on the servers, or perhaps after a restart but that I am not sure about.
Question 1: How can I prevent this error message?
Question 2: Are there any special things to think about when I need to restart the servers and replication is configured, e.g. after installing updates from Windows Update.
I would be very grateful for any answers regarding this.
Best,
/M

Please assist, the issue with SQL 2005 Browser and SQL 2000 Server Service is understood.
Our problem is with networked 2000 instances and SQL Express. The SQL 2000 machines (Standard & MSDE) do not have SQL 2005 or Express installed only 2000. When a SQL Express computer is put on the network with the SQL Browser service running almost all SQL 2000 machines lose sight of the other SQL 2000 instances. The second the
SQL Browser is turned off on the SQL Express box the SQL 2000 machines can see each others instances.
It appears that the response from the SQL Express SQL Browser causes the SQL 2000 machine to stop listening for responses. Once in a while one of the SQL 2000 instances will show up with the SQL Browser active on the network and it is my belief that it is because that response made it in before the SQL browser response. Please help as this does not appear to be a recognized issue. I'm assuming there aren't many sites running as many named instances on individual machines like we do.
Please note this appears to be a problem with SQL Express Browser not SQL 2005 Standard's which runs without problems on our network.
THANK YOU!

I have a table called employee_punch_record that we use to store employee time clock punches.
The columns are:
employeeid,
punch_timestamp,
punch_type (In / Out),
closed (bit used as status for open or closed pay periods),
ident
Here are some examples of a record:

We are using SQL Server 2008 as our database and use Access as a GUI. I am looking to create a form in Access where employees can access their time card and request changes from management. I want to use the format from the attached screen shot for the form. I pretty much know how to do it all, the only point of complication is trying to figure out the easiest way to get the transaction punch record data on employee_punch_record into a format where I can easily populate the form in the horizontal format you see in the screen shot.
I am not super strong in SQL, but figure I can do it using a formatting table of some sort. quick and easy way to move transaction records into a more horizontally oriented record?

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()

Response.End()
End If
DS.Tables(0).Rows(0).Delete()
Catch BUG as Exception
Response.Write(Bug.Message)
End Try
I removed all the connection stuff..
What I don't understand is why if ds.table(0).rows.count is zero I still get Bug.Message? I did Response.End ...
Thank you.

Hi. We are migrating a mainframe datacom database to SQL Server. One of our client-server applications already uses SQL Server. This application uses a middleware product to query and update the datacom database being migrated. We are considering using Service Broker to replace the middleware.
In many cases the client does not need a response provided the message is queued and will eventually get delivered. However, in some cases the client would like to wait for the message to be processed before proceeding. Is there an easy way to both submit and optionally wait for a response - with data - in a single stored procedure? If client does not want to continue to wait, is there a way to use a procedure to check for the returned message later?
We have not used Service Broker before and are doing for a "sanity" check before proceeding. We do not want to tightly couple the two databases at this time.

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.
Any help is greatly appreciated.

Hello everyone,
I have three merge publications that use web synchronization. The first publication works with no problem. When I try and sync the second publication, I get the following error messages:
"The operation timed out"
"The Processing of the response message failed".
So, I upped the query timeout from 300 seconds to 900 seconds. Now I get the following error messages:
"The connection with the server was terminated abnormally"
"The Processing of the response message failed".
I am using the Synchronize applet (found in the Accessories menu) to test my publications.
The third publication also works with no problem, so I do not see why the second one fails.
The only difference between the three is the following:
The first replicates a small handful of UDF's
The second replicates all tables (and has some filtering applied)
The third replicates all stored procs, views, and remaining UDF's.
Any ideas?
Thanks...

hi,
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 created a report in SSRS 2005 which is being viewed by users from different Time Zones.
I have a dataset which has a field of type datetime (UTC). Now I would like to display this Date according to the User Time Zone.
For example if the date is August 07, 2007 10:00 AM UTC,
then I would like to display it as August 07, 2007 03:30 PM IST if the user Time Zone is IST.
Similarly for other Time Zones it should display the time accordingly.
Is this possible in SSRS 2005?
Any pointers will be usefull...
Thanks in advance
