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
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....

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!

I have a service broker process that's in run-away mode and I cannot figure out how to stop it.
Here's the situation:
The stored procedure named in the activation queue is opening a transaction but not closing it. The receive loop has a timeout of 3 seconds, with MAX_QUEUE_READERS set to 5 so every 3 seconds I'm getting 15 new records in
sys.dm_tran_locks.
The server is at 99% CPU with no users on it.
The problem is I can't stop it. Here's what I have tried:
Reboot the box Clears the lock table and runs away again
ALTER QUEUE <Queue Name> WITH STATUS=OFF Just sits there forever
Drop the Service, Drop the Queue Just sits there forever
Dropped the stored procedure itself (!) It's still running like crazy
So my immediate question is how do I stop this crazy thing? And the follow up question is when a programmer makes a mistake, do we have to reformat our DEV box to recover from it (that's a joke) -- seriously how do you stop a run away service broker process?
Is there a way for a .NET application to receive a notification when a service broker queue has been updated with a new message? I tried using SqlDependency on an SB queue but I got an "invalid" error in my notification handler.
Such a notification would be much better than having to poll the queue every N seconds.
Thanks
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

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.
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.

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

----------------------------------------------------------------------------------------------------
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
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

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.

View 1 Replies View RelatedHi,
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 all,
I have several DTSX packages which send out report files by mail. For security purposes, the SMTP server can only be reached from specified IP addresses, from specified processes, with specified sender address. I know all this information, except the process name that sends out the emails in a DTSX package. So my question is, what process can be identified as the one that sends out the email?
Thx!!!

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,

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...
