Hi
I need some rough figures for replication performance. Can anyone give an idea of the number of concurrent subscribers a single IIS server can safely handle before having to move to load balancing with multiple IIS servers.
I would estimate the average daily row changes to be in the region of 500 to 2500 per subscriber.
Any ideas?
Many thanks

There was a 5 concurrent user limitation in MSDE (the version prior to SQL Express). Does that same limitation exist with SQL Express 2005?
Thanks.

Does anyone know how to reserve a number of concurrent user licenses /per server logins in MSSQL 2000?

Hi,I have a web app, that runs fine, except for one particular section that uses a class called by an event in the code behind. The class resides as a dll in the bin folder. We had no problems during testing, when only one user was running this dll. Problems soon occurred when multiple users tried running it. Here's the error & stack: 06/02/2007 09:25:26 ==> cburns ==> There is already an open DataReader associated with this Command which must be closed first. at System.Data.SqlClient.SqlInternalConnectionTds.ValidateConnectionForExecute(SqlCommand command) at System.Data.SqlClient.SqlConnection.ValidateConnectionForExecute(String method, SqlCommand command) at System.Data.SqlClient.SqlCommand.ValidateCommand(String method, Boolean async) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method, DbAsyncResult result) at System.Data.SqlClient.SqlCommand.RunExecuteReader(CommandBehavior cmdBehavior, RunBehavior runBehavior, Boolean returnStream, String method) at System.Data.SqlClient.SqlCommand.ExecuteReader(CommandBehavior behavior, String method) at System.Data.SqlClient.SqlCommand.ExecuteReader() at ESP.Validator.Data.DatabaseEvents.DatabaseEventManager.Read(IEventable eventObject, Int16 eventType, DateTime earliestDate, DateTime latestDate) in C:My PathValidatorValidator.NETDataDatabaseEventsDatabaseEventManager.cs:line 92 at ESP.Validator.Data.Translink.CATCard.GetDespatchDate() in C:My PathProjectsValidatorValidator.NETDataTranslinkCATCard.cs:line 94 at ESP.Validator.Data.Translink.ExistingSchemeEntitlement.ReadCards() in C:My PathProjectsValidatorValidator.NETDataTranslinkExistingSchemeEntitlement.cs:line 215 at ESP.Validator.Data.Translink.ExistingSchemeEntitlement.Read() in C:My PathProjectsValidatorValidator.NETDataTranslinkExistingSchemeEntitlement.cs:line 147 at ESP.Validator.Data.Translink.TranslinkApplicant.ReadEntitlements() in C:My PathProjectsValidatorValidator.NETDataTranslinkTranslinkApplicant.cs:line 369 at ESP.Validator.Data.Translink.TranslinkApplicant.Read() in C:My PathProjectsValidatorValidator.NETDataTranslinkTranslinkApplicant.cs:line 353 at ESP.Validator.Data.Translink.PrePrintedLetter.Read() in C:My PathProjectsValidatorValidator.NETDataTranslinkPrePrintedLetter.cs:line 282 at ESP.Validator.ValidationProcessor.Read(ValidationSubject subject) in C:My PathProjectsValidatorValidator.NETValidationProcessor.cs:line 82 at clear_applications_scan_applications.ProcessValidation() It seems the data reader is getting reused.

I administer a MS SQL Server 6.5 server which contains one principle user database. This application maintains an average of 400 to 450 active user connections under normal use. The server hardware consists of 4 PP200 CPU's, 1 Gb RAM, ATM NIC card, 64 Mb cache on the controller card and a RAID 5 configured storage with over 80 Gb of space. We have problems almost daily where users have trouble obtaining information from the database or fail to connect. The only errors I see in the error.log are "Lost connect" errors which are created due to users abruptly disconnecting from the database because they are tired of waiting for a response. I've ran a number of performance monitor checks which generally come up as expected. I have a few checks where they indicate that WinNT may not have enough memory but the memory allocation is approx. 25% WinNT (250 Mb) and 75% MS SQL Server (750 Mb). This should be more than enough for the WinNT OS.
Does anyone have any suggestions as to what I can do to help performance or other checks I can make that would tell me more of why I am having problems?
Any suggestions would be greatly appreciated.

We have an existing SSRS server, and have just created a new child domain. We'll be migrating users from the parent to the child, and want to add the users of that new domain with access to SSRS. In the parent domain they are able to access, but after migration with the child domain account, they cannot.
I have added the group CHILDDomain Users with a system user role on SSRS, and PARENTDomain Users was already there.
Is there any additional step I should/could take to get this active?

Hey,
MSDE 2000 allows 25 concurrent connections.
If these are all used up, and a 26th connection comes in. What happens? is the connection rejected? or does it sit in a queue, waiting to be given a connection?

hi
i hv developed an application that runs on the local windows system and interfaces with the MSSQL 7.0 database server using ODBC DSN Connections. This application will be deployed over the LAN with over 100 users.
The MSSQL 7.0 server has only 5 user licenses that limits the concurrent usage to 5 users.
I need a solution whereby all users can access the SQL server database without adding more licenses
Is there a way out.
Please help

Morning
I have been searching hi and low on the web to try and find out typically which version of sql server should be used based on the number of concurrent users you will be having.
I believe that Sql Server 2005 Express should only really be used for up to 10 concurrent users while I seem to remember that Standard edition supports up to approx. 33,000 connections.
Does anybody have this information to hand as I need to write a business case to justify the potential upgrade.
Many thanks

what happens when a package is run concurrently by 2 or more users. will the flow be in a queue, if not how is it going to be.

Hi Team,
In SQL Enterprise Manager, when we expand "Database -->Users", we see the

hey all,
MSDE will only allow 5 concurrent connections to ...
a particular database?
a particular instance?
or a particular server?
ie. if i have one application running on one instance of MSDE with 5 connections and i have another application running on another instance of MSDE with 5 connections. would i actually have 10 connections? **both instances on the same machine...
can someone please clarify.

Hi all
I have a stored proc that runs every 4 hours - as a job. The stored proc takes about 3-5 minutes to comple, depending on number of records.
To do testing we run that stored proc manually, also.
Sometimes 2 or more people may run the same stored proc without knowing that the other person is running. This may create duplicates entries once processed.
What I want to know is, Is there a way to check if that stored procedure is currently running. If so it wont run second time concurrently.
(May be semapohres,mutex or something like that?)
(I am trying not to use a table to store whether the stored proc is running or not)
Thanks in advance.

On my server running SQL Server 2000 (SP3). I frequently get thisinformational message in the Event Viewer log.17052 :This SQL Server has been optimized for 8 concurrent queries. This limit hasbeen exceeded by 2 queries and performance may be adversely affected.The application that I am running is a vendor application so I do not haveaccess to the code. I contacted the vendor, but they have never seen thisproblem and cannot recreate it. I checked the Microsoft Knowledge Base forhelp, but I came up empty. It seems like it should be a simpleconfiguration change.Any advice?Thanks,Jeff
View 1 Replies View RelatedI've been asked to turn our single-user database system into a multi-usersystem. At present, each user has a copy of the MSDE on their desktopmachine and uses our program to access it. In future, we would like tocentralise our MSDE instance and allow multiple users to access it. Inorder to facilitate this, we are going to only allow one user write accessto the system at a time (I know, its a kludge, but the system was neverdesigned for multiple users in the first place).I have a single, simple question this being the case: can I update a single"read-only" bit field in a table of the database in order to flag to otherusers that the system is in read-only mode in a way that avoids concurrencyissues? ie. does an "UPDATE" query lock and unlock? ( I suspect the answeris yes! ). If anyone else has experience of these things, I would alsoappreciate some tips on how best to proceed.ThanksRobin

I have a puzzle in my mind here. I will thank anyone who can solve my puzzle.
I am not familiar with SQL and its theories behind, so please bear with me if I am asking a stupid newbie question.
My puzzle is generally a problem of generating sequence numbers. The following SQL is only a stripped down version - it fetches the max number, add 1 to it and updates the table with the new number.
DECLARE @max int
SELECT @max = MAX(next_number) + 1 from sequence_numbers
UPDATE sequence_numbers SET next_number = @max WHERE next_number = @max
Now if user1 gets 100 and user2 also gets 100 and they both try to update the table, what would happen? I fear that the result would be 101.
One of my coworker thinks that adding 'WHERE next_number = @max' can solve the conflict - user2 will fail. His reasoning is like this:
After user1 updates the table, next_number would be 101 and user2's update will fail because his WHERE criteria is still 100.
But I think user2 still sees the old data (100) and still succeeds and thus both users update the table with number 101.
Thanks.
Hi and thank you in advance to whomever takes the time to read this entry. I will be as detailed as possible, so I apologize for the length. The information here relates to the automotive industry, but I don't believe that is a very important detail
The overall purpose of this query is to create a compressed set of the data that exists in the database. The de-normalized information is structured like the following (including made-up data):
Code Block
PartNumber Make Model Year
-------------------------------------------------------
835100 ACURA INTEGRA 2004
835100 ACURA INTEGRA 2003
835100 ACURA INTEGRA 2001
835100 ACURA INTEGRA 2000
835100 FORD FOCUS 2002
There is any number of part numbers, makes, etc in this mix. The query that I currently use is utilizing MAX and MIN functions to determine year range, but as in the sample above, this does not take into account the fact that there could be a year skipped in the middle. I could probably use a cursor to do this, but would really like to stick to set logic if at all possible.
My existing query is:
Code Block
SELECT DISTINCT
cwi.PartNumber
,RTRIM(lv.Make) AS Make
,MIN(lv.Year) AS StartYear
,MAX(lv.Year) AS EndYear
FROM
CWIParts AS cwi
INNER JOIN PartTypes AS pt
ON cwi.PartTypeID = pt.PartTypeID
INNER JOIN PartDetail AS pd
ON cwi.PartNumber = pd.PartNumber
INNER JOIN Status AS s
ON pd.StatusCode = s.StatusCode
INNER JOIN LegacyVehicle AS lv
ON cwi.LegacyVehicleID = lv.LegacyVehicleID
WHERE
cwi.PartTypeID = 10
AND s.Status = 'Active'
GROUP BY
lv.Make
ORDER BY
cwi.PartNumber ASC
,cwi.Make ASC
In hopes to end up with a result set that has 1 row for each unique part-number, make, and consecutive year range relevant to the part-number and make. I will also need to add the functionality to add other attributes (such as Model and Liters), but those are equality based and can be passed in easily.
I had done most of this programatically in vb.net, but I would much rather push this logic back to SQL Server. Thank you all for any help that you can provide on this topic.

Hi,
I read that there's a "tecnical" limit of 32767 concurrent connections for SQL 2005 Express, and that SQL 2005 Express uses only 1GB of memory. So, what's the number of practical concurrent connections SQL 2005 Express can handle? Is it 200 ,300, 0r 400...? How much memory is consumed by every connection?
Thanks in Advance.
