Hi All,
I want to send notification to SSRS on change in database for that I am using SSB to send message to SQL Server Reporting Services.
Can I use SSB and if yes, how? Please guide me I am new to this.
Thanks,
Omkar.
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]
AS
BEGIN
SET NOCOUNT ON;
DECLARE @conversation_handle uniqueidentifier
DECLARE @message_body AS VARBINARY(MAX)

@conversation_handle = conversation_handle,
@message_body = message_body

), TIMEOUT 1000;
IF (@@ROWCOUNT = 0)

My endpoints are created like so:
CREATE ENDPOINT MyEndpoint
STATE = STARTED
AS TCP
(
LISTENER_PORT = 4022
)
FOR SERVICE_BROKER (AUTHENTICATION = CERTIFICATE MasterCertificate)
GO
GRANT CONNECT TO CertOwner
GRANT CONNECT ON ENDPOINT::MyEndpoint TO CertOwner
GO
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,

Hi,
The project I'm currently working on has to be relatively simple for the users to install, so I had the idea of using service broker to "set itself up". The idea is that there will be a server with a service and suchlike already set up. Somehow the clients will get the information required to create a remote service binding, and once that has been accomplished will send a registration message to the server.
What I'm wondering is can I somehow create and send a certificate using service broker via t-sql, and also is this approach reasonable or is it a bad idea. The reason I had thought of something like this is because the people setting up the client sites may (and probably will) have very little knowledge (probably no sql server knowledge) so we need the installation to basically be a click and install.
Thanks in advance,
Adam
Hi,
i have a service broker application that i send message to the queue and a specific SP reads the message and process it, part of this processing is sending the information found on that message to a specific email accounts. this means i have two service broker applicatins, one for my business (sending messages to queue to be processed and the secound one is the SendEmail service)
when i send email using the SP "msdb.dbo.sp_send_dbmail" the email is recieved 100% true, but when i come to send the email through the SP which recieve the messages from the SB queue, the email is not sent and i dont know where it goes.
this means that i cant read from a queue and send to another one at the same time... can you help me in this!

Hi There
I have a table at my initiator, i have a copy of this table at my target, every morning i want to refresh the table at the target with the data from the initiator via service broker.
What would be the best way to do this?
One major consideration would be that this table would be very large +- 1.6 million rows.
I was thinking of exporting the table to file like a csv, compressing the file and then sending it via service broker. Then at the target i would uncompress and bulk copy the data into the table at the target.
But can this be done?
How would one go about sending a file via service broker?
For example if i wanted to send a .csv or something via service broker how would i do it?
I know i can send binary data, but i would have to equate the msg to a file on disk, and how exactly would a recieve this file on the other side and make sure it went to disk at the target, i am guessing it is a mixture of xp_cmdshell and service broker.
Can this work?
Or is there a much simpler way? Any thoughts would be appreciated.
Thanx
Hi,
I have a small problem with my two databases ( A and B ).
On database A I have a queue set up for receiving messages from a service broker which are sent via a stored procedure from database B ...
Each time a message hits the queue on database A I would like to run a stored procedure that takes the message and actions it.
I have my stored procedures in place but can't figure out how to trigger a procedure each time a message is received. I have read this ( http://technet.microsoft.com/en-us/library/ms171601.aspx ) but would really appreciate someone posting an example of setting up queue activation.
Many thanks
Chris
I have an app receiving messages from SQL Service Broker when data is updated. (Messages are located at http://msdn2.microsoft.com/en-us/library/system.data.sqlclient.sqlnotificationinfo.aspx )
When I run this app against a remote SQL Server, I receive the message "Updated" which I expect.
But when I run the same app against the local machine SQL Server, I receive the message "Options".
Does anyone know if there are SQL Server options that must be set to certain values?
I can't seem to find anything that troubleshoots this message... either from a SQLServer- or a .NET standpoint.
How do you set up the service broker to process an email message, and how do you format that message and send it to the que.
Can the service broker alos process an html form from a que.
Thanks
One of my customers' SQL Server 2005 databases, which was set up to receive messages from another SQL Server 2005 database on another server has been re-installed by the customer and now the message passing no longer works. After recreating the End Point and re-enabling the Service Broker on the target database, I am now getting messages in the SQL Server error log.
An error occurred in the service broker message dispatcher, Error: 15581 State: 3.
and
Error: 9644, Severity 16, State: 14.
The two errors repeat alternately ad nauseum.
Running a trace on the target database server, for the Broker:Message Undeliverable, gives an endless stream of these entries:
This message could not be delivered because an internal error (code 15581, state 3) was encountered while processing it. Check the error log for more information.
Any ideas on how to fix this system?
Hi,
I am using service broker in between two database servers. following is the way i am sending and receiving messages
Send
BEGIN TRAN
BEGIN DIALOG CONVERSATION @handle
FROM SERVICE @SendService
TO SERVICE @ReceiveService
ON CONTRACT @Contract
WITH LIFETIME = @lifetime;
SEND ON CONVERSATION @handle
MESSAGE TYPE @xmlMessageType(@xmlMessage);
COMMIT
Receive
BEGIN TRAN;
RECEIVE TOP(1) @xmlMessage = message_body,
@handle = conversation_handle,
@message_type = message_type_name
FROM TransactionQueue;
----------------------------------------------------------------------------------------------------
-- Check to make sure a message was returned to process. In theory this should never happen.
----------------------------------------------------------------------------------------------------
IF @@rowcount = 1
BEGIN
IF @message_type = 'http://schemas.microsoft.com/SQL/ServiceBroker/EndDialog'
BEGIN
END CONVERSATION @handle;
COMMIT
RETURN 0
END
IF @message_type = N'http://schemas.microsoft.com/SQL/ServiceBroker/Error'
BEGIN
RAISERROR(N'Received error %s from service [Target]', 10, 1)
END CONVERSATION @handle;
COMMIT
RETURN 0
END
SET @sql = 'EXEC '+@message_processor_name+' @xml'
BEGIN TRAN
EXEC sp_executesql @sql, N'@xml XML', @xml=@xmlMessage
COMMIT TRAN
END CONVERSATION @handle;
END
COMMIT
I see Messages are delivered to the target every thing working fine other than following errors which i am seeing in profiler.
1) "This message could not be delivered because the conversation endpoint has already been closed." I see this error on initiator end. Is it like ending conversation on initiator end when i get "EndDialog" send an acknowledgement, which cannot be recieved by target as it has already ended conversation.
2) "An error occurred while receiving data: '64(The specified network name is no longer available.)'." I don't have much idea about the reason for this error. But in profiler i see value for GUID is different for this error and the real message.
Let me know if you need any other information
I've got a situation where I want to put request message on a queue. Because starting a conversation is the only way to put messages on a queue I have to start a conversation with myself. So my Begin Dialog Statement looks something like this:
DECLARE @conversation_handle UNIQUEIDENTIFIER;
BEGIN DIALOG CONVERSATION @conversation_handle
FROM SERVICE [ServiceName1]
TO SERVICE 'ServiceName1'
ON CONTRACT [ContractName1]
WITH ENCRYPTION = OFF;
SELECT @conversation_handle AS ConversationHandle
I haven't noticed any problems with doing this but I wanted to know if there was anything wrong with it. Does someone know what problems this might cause?
I was trying to send a message on a different instance in the network using service broker. I have created the endpoint and route both the side. I could see that the messages are in the transmission_queue in the sender side with no error in the status.
What could be the reason.
I am doing the following:
CREATE ROUTE inst02
WITH
SERVICE_NAME = 'SERVICE2',
ADDRESS = 'tcp://10.14.43.149:2341'
in the send script i am using this:
BEGIN DIALOG CONVERSATION @dialog_handle
FROM SERVICE [SERVICE1]
TO SERVICE 'SERVICE2'
ON CONTRACT [MainContract] WITH ENCRYPTION = OFF ;
in the sending side if i change the endpoint's authentication as windows kerberos , then i get thefollowing error in the transmission queue:
"Connection handshake failed. An OS call failed: (8009030e) 0x8009030e(No credentials are available in the security package). State 66."
I also have given access to the remote user on this endpoint(on the recever side) using this :
GRANT CONNECT ON ENDPOINT::Endpoint_test to paras
I am executing the sending side send script using the same user wich has access to the remote endpoint.
Can some one resolve this issue.
Thanks
when ever I send my message thru Service Broker I am getting an error message like this "
"Dialog security is not available for this conversation because there is no remote service binding for the target service. Create a remote service binding, or specify ENCRYPTION = OFF in the BEGIN DIALOG statement."
This I found in sys.transmission_queue
Please reply with your comments
Hi,
I have an c# windows service, which is running on the same machine where my mssql server is installed. This service must be informed for each insert/update/delete event on one specific table.
My idea was to create an CLR Trigger for this table which can communicate with this service via .NET remoting. But the problem is, that the system.runtime.remoting assembly is not integrated within the mssql clr enviroment => i can't use remoting.
Are there any other idea's how can i solve this?
Best regards,

How to prevent the hang on the initator service broker if the target service broker is not started?
Our case has two service brokers (two databases), sometime, the target is need to turn off. But the sitation is the initator service broker (in fact, the message is sent from triggers) become hang, I want to prevent this case and continue to operation, and the messages should queue and will continue to send to target service broker when it startup. How should I do?
Hello, I receive this error "The SQL Server Service Broker for the current database is not enabled, and as a result query notifications are not supported.

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
Hello,
Has anyone seen this in profiler? I have two brokers on different servers with one of them being the initiator. All messages end up sitting in the initiator's transmission queue. Profiler on the target broker's machine displays this for every attempt to send by the initiator:
A corrupt message has been received. The End of Conversation and Error flags may not be set in the first sequenced message. This occorred in the message with Conversation ID '...', Initiator: 1, and Message sequence number: 0
In case it's relevant encryption is disabled and endpoints on both servers use windows authentication.
Any hints are greatly appreciated.
Regards,
Svega
In profiler i see next error:
"The message could not be delivered because it could not be classified. Enable broker message classification trace to see the reason for the failure."
Where and what should I enable? I enabled all in "Broker event category" of the profiler.
Thanks
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...

Hi,
I know that is possible to programmatically send an e-mail with the command xp_sendmail, but i want to know if it's possible to programmatically send a Net Send message.
Martin
I'm trying to figure out how the SQL Agent sends email through jobs using the notification option for operators. I have had little success using SQL mail so I want to use an alternate such as blat. I have not been able to find where the SQL jobs are actually sending the mail. Can someone help please. OI have checked the system stored procedures without suscess. I'm using SQL2000.
Thanks,
Steve
Do you know a stored procedure ( or a query) to send a message to a SQLServer user ?
Something like NET SEND but with a spid user
Thanks
I am having a problem getting informational type messages to display for my end users.
I have a SQL2000 db with a Delfi front end. When I issue either the raiserror or print nothing is displayed inside the app. With raiserror I can get it to display if I make the severity higher than 10. The problem with this is that it stops the app from processing the transaction. This is ok in one case but not with just informational type stuff. Any suggestions? Thanks.

Say i want to send a blob in a message from queue A to queue B. These locations can be geographically different. How can i implement this ?
Also anything which i want to send as a message should be stored in the database. and then I should store it in a variable. this can be used as the message body. am I right ?

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,
Is it possible to develop Service Broker in .Net 1.1 (VS 2003)? Currently I have a project developed in .Net 1.1 and I want to add a new method utilize the message queue concept (instead of using MSMQ, using Service Broker SQL 2005), although my DB is SQL server 2005.
Thanks,
