SQL SERVER 2005 Service Broker
Jul 23, 2007
Does SQL SVR 2005 Service Broker use connection pooling?
We are building a laptop application that will use SB to send messsages
to one SQL SVR 2005 instance. SQL 2005 Express will be installed on
each laptop and will be the "sender" to one SQL SVR instance, the "receipient"
It will be deployed to over 1500+ laptops. Each laptop will have a different
IP address.
Our SQLDBA wants to know if each of the laptops will use a different
connection when sending messages?
I answered "Yes", but another team member said "No".
What is the correct answer?

I created the table dbo.customer from the orginal table sales.customer. dbo.customer works but sales.customer does not. WHY? We took the time to design our tables under different schemas to help control, organize and assign permissions.Private Function GetCustomers() As DataTable
Dim sqlconnection As New SqlConnection(WebConfigurationManager.ConnectionStrings("connectionstringAlliance").ConnectionString.ToString)WORKS:Dim command As New SqlCommand("SELECT CustomerID, CustomerType FROM dbo.Customer WHERE CustomerID=1234", sqlconnection)DOES NOT WORK:Dim command As New SqlCommand("SELECT CustomerID, CustomerType FROM Sales.Customer WHERE CustomerID=1234", sqlconnection)
Dim dependency As New SqlCacheDependency(command)
Dim dad As SqlDataAdapter = New SqlDataAdapter(command)
Dim customers As New DataTable
dad.Fill(customers)Cache.Insert("Customers", customers, dependency)
Return customersEnd Function Protected Sub Page_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.LoadDim customers As DataTable = CType(Cache.[Get]("Customers"), DataTable)
If customers Is Nothing Then
customers = GetCustomers()
Label1.Text = System.DateTime.Now.ToString()
End If
gridviewCustomer.DataSource = customers.DefaultView
gridviewCustomer.DataBind()
End Sub

We are looking for some guidance with an issue we have picked up with our implementation of Service Broker here on the ABSA Capital project and I am hoping you can help or point us in the direction of someone.
The architecture we have implemented for service broker is to make use of an Activation stored procedure on two queues (1 SP per queue) to process the messages received. What we have found is that the activation stored procedure runs on a background session and its CPU time and memory just grows to the point where it brought one of our UAT servers to a grinding halt.
Is there anyway we can reduce the memory consumption of the activation stored procedure or is this one of those things that still need to be ironed out in Service Broker?

Back in July I released the (then) latest version of SsbAdmin. For you who
don'r know what it is; it's a tool which allows you to graphically administer
SQL Server Service Broker.
I have now uploaded a new version which is compiled against the released
versions of SQL Server 2005 and .NET 2.0.
You can download it from here: [0].
After download, un-zip to some directory and read the README.doc file.

We have a number of large binary xml messages. I would like to compress the XML before converting to VARBINARY as much as possible. What is the recommended way to handle this if the conversions are happening in TSQL? I will also need to be able to decompress in .NET code, so I'm wondering if the best way is to just use CLR Integration for the marshaling routines, rather than building the marshaled structure in SQL. Any suggestions on reducing the XML payload size for extremely large messages?

Hi
I am presently working on a requirement involving a central SQL store replicating data with 600+ stores.
Presently the no of stores is 300 and it would eventually more than 600+ shortly.
What would be the best option to use in this scenario?
I am told that for more than 600 stores the replications would serioulsy impact the performance and SSB would be more advisable.
Now i am newbie on SSB and would like to know from the experts whether its a correct way of implementation
TIA

Hi,
I am struggling with the position SSB could take in an SOA. If I would want a broker in the general sense, meaning an intermediary sitting between applications which exchange information through messaging, would SSB be a good candidate? I know Biztalk is probably the primary candidate, but in my scenario I would end up with Biztalk apps with empty orchestrations. Also, I think Biztalk is more expensive to manage. So I am looking for a lightweight broker for a simple SOA targeted at application interoperability, no fancy business processes in sight.
I look forward to some responses.
Kind regards,
Neeva

Can't believe no one has commented on this in here yet. If you're into SQL Server Service Broker (and you are if you are reading this forum), you must go over and take Rushi's Service Broker Challange.

Recently there has been questions on some of the newsgroups about examples for SQL Server Service Broker. So, yesterday on a flight back to England I crofted up three different SQL Server projects as examples: LocalSampleRemoteSampleServer1RemoteSampleServer2
All three examples are jus your very basic Hello World? example, but they show: LocalSample communication between two databases on the same SQL server instance. MasterKeys in a database and the database being TrustWorthyRemoteSampleServerX These two samples are meant to run on two different machines/instances and in the samples you set up both transport security and dialog security by using Certificates.
Download the zip file from here [0], unzip and read the README.txt file, and Have Fun!!

I have configured a non-SQL linked server (via an OLE DB provider) and I wish to insert data into it via Service Broker but I am getting the following error in the SQL Server log:
The activated proc [dbo].[sp_ mytableServiceProgram] running on queue TestDB.dbo.mytableQueue output the following: 'Cannot promote the transaction to a distributed transaction because there is an active save point in this transaction.'
As you see below, my strored proc. is not issuing any 'save trans' statements, so why is it not allowing me to wrap my code in a transaction? How else can I use a transaction (in order to not lose anything from the queue) and yet still be able to insert to the linked server?
CREATE PROC sp_mytableServiceProgram
AS
SET NOCOUNT ON;

@MessageTypeName = message_type_name,
@MessageBody = message_body,
@Dialog = conversation_handle
FROM mytableQueue
), TIMEOUT 2000 ;
-- If RECEIVE did not return a message, roll back the transaction
-- and break out of the while loop, exiting the procedure.
IF (@@ROWCOUNT = 0)
BEGIN
ROLLBACK TRANSACTION;
BREAK;
END ;
SET @XML = CAST(@MessageBody AS XML);

I have an application that is reading a message from a Service Broker Queue. When I use integrated security with an NT account it works fine. When I use a SQL Server User through Management Studio I can select from the Queue however, when I use this same account through the web app with the SQL Server User, I cannot see the Queue. Is there a grant that I must do to this account to get it to see the Service Broker Objects?

I am writting a huge Service Broker Application. I notice that each message that is processed appears in the SQL Server Logs. Currently I am just testing with a single queue and tons of messages are showing up in the log. Is there a way that I can turn these informational messages off? I think in the end I may have something like 15 or 20 queues. These messages are very useful for debugging but I may not desire this extensive logging to be running all the time on all of my queues.

I had to restore a database in one of the staging servers the other day. However, upon completion, I found out that the service broker queue in the database is not working anymore. The service broker queue error was similiar to this error:
The activated proc dbo.procedure_name running on queue database_name.dbo.queue_name output the following: '<error message>.'

Let's say that I have a stored proc that is assigned to a service broker queue and is constantly running while it waits for messages in said queue. When a message comes in on the queue, the stored proc creates a table variable based off of the contents of the message and performs various operations with the data. Since the stored proc is constantly running, do the contents of this table variable ever truly get emptied? Should I be deleting the contents of the table variable at the end of the operation to ensure that stale data doesn't persist?

I am trying to send a message between to SQL Server 2005 instances on two different machines. I have checked all my routes and all my objects appear to be setup correctly. However, when running Profiler on the target machine, I receive the "This message has been dropped because the TO service could not be found. Service name: "[tcp://mydomain.com/TARGET/MyService]". Message origin: "Transport". This is my activated stored procedure that is sending the message to the target service. I am using certificate security. Any help appreciated....
CREATE PROCEDURE [usp_ProcessMessage]

BEGIN
SET NOCOUNT ON;

)
FOR SERVICE_BROKER (AUTHENTICATION = CERTIFICATE MasterCertificate)
GO
GRANT CONNECT TO CertOwner
GRANT CONNECT ON ENDPOINT::MyEndpoint TO CertOwner

And my routes like so:
GRANT SEND ON SERVICE::[tcp://mydomain.com/INITIATE/MyService] TO CertOwner
GO
CREATE REMOTE SERVICE BINDING [MyCertificateBinding]
TO SERVICE '[tcp://mydomain.com/TARGET/MyService]'
WITH USER = CertOwner,

I am doing some research to see if the Service Broker technology would help my company with our Enterprise application. Here is our scenario: We have a 3 tier system. The first tier needs to contact the second tier asynchronously. Hence, using queues is a good option. However, the process that needs to happen on the second tier is mostly process intensive with little database updates. Is it still worth our time to use Service Broker?
I like the concept of Activation that Service Broker provides. But, from what I am reading most of the documentation describes activation as a way to call another stored proc. I definitely dont' want to do any process intensive work on the SQL server. So here comes my question...
How would I use a windows service to listen to the activation event from the Service Broker. I could have multiple windows services watching the same queue (scalable). Would I have to handle collisions myself? If so, I think I would rather keep it simple, and just use a simple table as my queue.
Thanks for your comments in advance...
Vijay.

Hello , I am trying to Implement distribution of the Stock Quotes over the LAN(only within the Network) and showing the live changing stock Quotes on the front end (in datagrid) installed at each clients desktop.I am receiving the Stock prices over the TCP / IP from the Stock Exchange. I am recieving atleast 10-15 messages per second over the TCP / IP from the Stock Exchange. Now i need to distribute this feed to Each connected client.
I tried doing it from TCP / IP , but in vein. Can we install the SQL 2005 Database Client Version on every client and use Service broker instaed of Live TCP / IP connections programmatically?
Ideally Can i dump the meesages from Stock Exchange in to each connected client's database locally and each front end application will keep a record of all the incomming messages.i.e Front end have a notification event , it will referesh the Datagrid in Front end accordingly...
ALL my front end application are made in dot net
Pls suggest if this above workflow will help me

Hi,
I am looking at the Service Broker as a way to notify multiple clients that there has been data changed on a table in the shared database. These clients may or may not be online. When there is a change, the notification should fire off a query to refresh the clients local cache. Is this a situation where Service Broker would help me? Can multiple clients recieve the notification at different times ( some recieve while online, some recieve when they come back online)? Any help on this would be appreciated. It seems from what I read that the messages are pulled off the queue when a notification has taken place. Is this correct? If so, can I set it to behave differently?
Thanks,

Let's assume the situation: we have Initiator and Target. Target is behind ISP's NAT and can't be published outside. So, when Initiator sends a message to Target, Target will not be able to establish a backward connection and will not send an acknowledge. Initiator will retry and retry...
