Service Broker Activation
Jan 12, 2006Hi
I'm having problems with activation. I have a CLR stored procedure that runs fine when run directly (and consumes messages from the queue). When I try to enable activation nothing happens. I've tried different execute as options and looked in the sql server logs and I don't see anything indicating why.
I've checked sys.service_queues and all options look correct including activation options. The sys.dm_broker_activated_tasks view is empty.
Without any errors I'm having difficulty tracking down the problem. I've seen references to service broker shutting down the procedure if it doesn't consume any messages but I haven't seen where this is indicated.
Any help appreciated.

Internal Activation Of Service Broker
Nov 1, 2006Hi, there,
I'm a Chinese fan of Microsoft SQL Server 2005. Through studying for MS SQL Server 2005, now I have a question about €˜internal activation of service broker€™.
At the moment I have done a test. The description of test is as following:
Firstly I set the status of the activation to be off (ALTER QUEUE [dbo].[TargetQueue] WITH STATUS = ON , RETENTION = OFF , ACTIVATION ( STATUS = OFF , PROCEDURE_NAME = [dbo].[Usp_HelloWorld] , MAX_QUEUE_READERS = 5 , EXECUTE AS N'dbo' )). And filled the queue with100000 Messages. Then that running another application caused the usage of the CPU achieve 100%. Secondly reset the status of the activation to be on and monitored the €˜sys.dm_broker_activated_tasks€™. The instance of the stored procedure got the maximum number 5 very quickly. The server was much slower at current.
The SQL Server 2005 Books Online says: €™an activated stored procedure typically processes one or more messages and returns a response to the service that originated the message or messages. When messages arrive faster than the stored procedure processes messages, Service Broker starts another instance of the stored procedure, up to the maximum number defined by the queue.€? But it doesn€™t mention the performance counter of the server, for example: If the usage of the CPU is very high, the queue readers should be as few as possible, even don't process the message of queue until the system is idle. Because a client choice service broker means he don€™t care immediately process message, contrarily he care the throughput of the system and don€™t bother the natural application.
So my question is whether the strategy of internal activation of service broker doesn€™t care the performance counter of the server, just care the speed of process message. And the priority of queue monitor in SQL Server€˜s internal processes. Unfortunately I can€™t find any information about these from books online and Internet.
Raiserror In Service Broker Internal Activation Stored Procedure
May 17, 2006I use Try ... catch blok in my activation stored procedure. When SQL Server raise error (e.g. Primary key violation) in Try blok, XACT_STATE in Catch blok has value 1 = commitable transaction and I can use rollback transaction to savepoint. But when I use Raiserror() in Try blok, XACT_STATE in Catch blok has value -1 = uncommitable transaction and I can't use rollback transaction to savepoint. When I drop automatic activation for given queue and I run this stored procedure with Raiserror(), XACT_STATE has value 1 = commitable transaction.
What a problem may cause this different behavior ?

SQLCLR +Enterprise Library Data Access And Service Broker Internal Activation
Mar 10, 2007I am trying to find a solution to my woes creating CLR activation stored procedure that references Enterprise library data access dlls. Does anyone know best practices to deploy .NET 2.0 assemblies as SQLCLR. I am using VS2005 SqlClrProject to deploy my .NET 2.0 assemblies to Sql Server and it fails with error such as "Assembly was not found in the sql catalog". If I manually try to load a referenced assembly within SqlServer by browsing to the target location, like for example, System.Management.dll it fails with similar error, trying to resolve its dependencies. Even if I manage to walk through the dependency tree and resolve it to the final dependent dll, I am only able to load it in "UNSAFE" mode. Any recommendations, suggestions and feedback are welcome.
Thanks in advance.
SQL Server 2005 Service Broker - Activation Stored Procedure Memory Usuage
Nov 9, 2007We 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?
Troubleshoot Distributed Service Broker App
Jul 25, 2006Hi There
Ok i have done the following on my target instance i have created an endpoint, xml schema, message types, contact, activation sp , queue and service.
On the initiator i have created an endpoint, a route to the target service, same xml schema, same message types, same contact, queue and service.
When i try test this by doing the following:
SET @msg = CAST(@body AS XML)
BEGIN DIALOG CONVERSATION @dialogHandle
FROM SERVICE
[http://ewx.co.za/DemoInitiatorService]
TO SERVICE
'http://ewx.co.za/DemoService'
ON CONTRACT
[http://ewx.co.za/DemoContract];
SEND ON CONVERSATION @dialogHandle
MESSAGE TYPE [http://ewx.co.za/DemoMessage]
(@msg);
END CONVERSATION @dialogHandle;
END
================================================================================
Nothing happens and i dont know where to troubleshoot, if i check both queues they are empty ? I have altered the queues so that retention is ON.
I have checked the sql log of both instances and nothing.
When i execute the above sql it executes succesfully, so basically i am stuck i can execute the dialog sql, and set the activation on the target queue to OFF , so if i message gets there it should stay in the queue, but both que's are empty and no errors ? Not sure where to even start checking the issue ? For all i know the contract could be incorrect or port 4022 blocked or the endpoints not working, but i dont know where to find these errors other than the sql log and it has no errors ?
PLEASE HELP.
Thanx

Dec 13, 2007
Hello everybody!
We are developing a distributed application based on Tree Network Topology. Any part of this application knows only for one parent part and all children parts. For synchronize data with parts of this application we using SQL Service Broker.
Every part contains database. Let€™s name it €œSB€?. This database contains one QUEUE for received and sent messages, MESSAGE TYPE, CONTRACT and SERVICE. Any Service on part has unique name. Also there are one REMOTE SERVICE BINDING and ROUTE for parent part (service) and on one fore every child part (service). For each link Source €“ Target we create separate conversation_handle:
"BEGIN DIALOG @ConversationHandle FROM SERVICE [Source] TO SERVICE 'Target' ON CONTRACT Contract WITH ENCRYPTION = OFF;"
All works fine, messages sends and received quite well.
But if we have opposite messages in one moment, with probability 100 percent one of messages, will be missing. Why it happened? Is duplex is not supported in Service Broker? May we do something wrong? Anybody encounter this problem?
We using flag retention = on for queue, to analyze messages after they processed. Body of Message that sent into several services (in one transaction) absent in that service from which the message during the same moment has been sent.

Conversation Handle Processed By An Activated Stored Procedure Service Can Not Be Invoked By A CLR Service Instance?
Dec 1, 2006I have a initiator and a target service broker peer.
Both are controlled by a C# unit test. The initiator uses the Microsoft.Samples.SqlServer class. The target service uses stored procedure activation.
Sending a message from the initiator to the target, saves the content of the message, along with its conversation handle in the target's database specific table.
The unit test needs - at a later time - to instruct the target to send a message back on the same conversation handle to the initiator service.
For this the C# unit test creates a Conversation off of the saved conversation handle:
Service client = new Service("cleintservicename", conn, tran);
Conversation dialog = null;
dialog = new Conversation(client, convHandle);
Sending the message on this dialog generates an error "Message body: <Error xmlns="http://schemas.microsoft.com/SQL/ServiceBroker/Error"><Code>-8495</Code><Description>The conversation has already been acknowledged by another instance of this service.</Description></Error>".
Is the error due to the fact that a service - using the activated stored procedure already picked up the conversation, so that a new reference to the service can not be created through the Service class in CLR?
If so, I might need then to skip the activated stored procedure in favor or a CLR service, alltogether?
Any help - greatly appreciated.
Query Distribution Using Service Broker
Mar 28, 2006Hello ,
I am wokring on an application where in I am migrating the legacy application to SQL server. for this when ever I make any changes to the legacy application,I immediately move this changes to SQL, using insert/delete/update to SQL.
I also want all these data on 2 to 3 other SQL servers which are on different remote machines. for this i thought of using the service broker to send the query as messages.
So on the initiator(where the legacy application reside), i create 2 to 3 queues(based upon number of receivers) and each time a query is successful on the initiator, i move these messages(queries) to the initiator queues and send them to the various targets. on the target i just pop these messages and execute them so that the query run on the all the targets and all my databases are in synch.
I need some info on various operations on the Service broker queues like:
1.How do i insert/update/delete from the queue.
2.Can i set some size constraint on the queue
3.Can i get the info like when the queue is full.
4.Can i set some custom flags on the queue like, queue is invalid or valid(setting and getting these falgvalues).
5.Clearing the entire queue.
These are the operations, i need on the queue for various use cases(failure cases)
Can you point to some documentation/tutorials whihc sheds more light on these queue operations.
Thanks,
Query Notifications/ Service Broker Problem
Sep 11, 2006Hey , I encountered a problem using SqlDependency and notification services.
I€™ve created a database with tools from c# Express 2005 and attached it to the sql server express 2005. And it turned out that €˜dependency_OnChange€™ in my application is triggered each time I execute the command.ExecuteReader(); and it shouldn€™t, because the command is just the select statement of columns and rows for which I wait to be modified.
SqlDependency dependency = new SqlDependency(command);
dependency.OnChange += new OnChangeEventHandler(dependency_OnChange);
command.ExecuteReader();//when the program gets here dependency_OnChange is called
So I Used the example from here :
http://msdn2.microsoft.com/en-us/library/a52dhwx7.aspx
and with AdventureWorks it behaves as it should , but when I change the connection string and select statement in the example to work with MyDatabase, the problem appears again.
So there is something wrong with MyDatabase ?
The select statement I used was €œselect Name, Pass from Users where Name like €˜L%€™€?;
So theoretically this should work but it does not and I end up in an infinite loop with
dependency_OnChange called cyclically €¦
I€™d be grateful for any advice !
Error: Service Broker && SQL Query Notification Errors

Query Notification - Subscription Created But Not Firing Service Broker Endpoint In Status SO
Mar 12, 2007Hi,
SQL Server 2005 SP1. (+ 5 minutes fix installed).
Query notification subscription cretaed (sys.dm_qn_subscriptions).
Subscription does not fire in response to event.
sys.transmission_queue is empty.
profiler does not show errors.
sys.conversation_endpoints shows one endpoint in status SO. (along with a lot of left over garbage - about 300K records - but this should not be a problem other than storage).
I know SP2 is suppose to solve the garbage records problem but this is not our problem. This setup was working and then just stoped.
any ideas ?

Architectural (broker) Place Of SQL Service Broker
Apr 5, 2007Hi,
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
Distributed Processing Farm Using Broker For Middleware.
Sep 26, 2006In our current project, we are attempting to use Broker for the middleware for a "queuing" solution that helps in throttling & load-balancing incoming messages. These messages could potentially be either long-running jobs or simply an incoming flood of messages received from our integration web services that are called upon via BizTalk.
For the posting of messages onto the "to do" queue, we are implementing the "fire & forget" pattern that has been discussed here previously and on Remus' blog. This aspect of the design seems to work fine for us. Currently we have this setup where activation is occuring on the target queue, but we don't want to hold open a thread there on the server while waiting for our synchronous calls to various web-services on the processing "farm" to complete.
The next evolution of our design is to try and move activation from off of the primary SQL cluster itself (i.e. activation is currently happening on the clustered SQL boxes) onto the individual processing nodes. For this model, we are looking at using SQL Express on each of the nodes as has been suggested here on the forums for other similar scenarios.
For resiliance to any node failures, we do not want to "route" the messages to the individual nodes hosting their own queues but rather have those nodes do a "read" from the primary queue and do the per-message processing and performing either a committed EndDialog of EndDialogWithError based on the success of processing each task/message.
To invoke the processing on each of the nodes, we need some form of mechanism to send a "wake up" and do the "reads" since no message is being sent to the node itself for any form of activation based on a queue that receives the actual "job". On the same hand, we are considering having a "wake up" queue on the nodes where a simple "wake up" message could be sent to all nodes/queues and then activation on those queues would then invoke the processing "loop" for each node.
My question is how to best establish this "wake up" call to each node. I think I've read about a queue that is internal to Broker itself that receives a message when new items are received in any queue. My initial thought is to put activation on that queue and have a procedure that sends the "wake up" to each of the nodes in our processing farm.
I am looking for any input where others have attempted to solve this type of problem with Broker.

Bradley A. Hehe
Distributed Broker Queue Performance Issue
Aug 7, 2007Hi,
We are doing a POC for transferring a huge number of messages(millions) from oner machine to another. The two approaches we are examining are MSMQ and SQL Broker. The MSMQ is set up as a remote queue on the target machine, and the source machine takes as little as 1 millisecond to send the message (using a .NET program). However, when testing on Service Broker, we find that the time taken to send message to the queue is significantly higher - like 70 millisecond. Could you please help us in understanding why this is happening?
The service broker distributed queues have been set up as per the directions in the posting at http://www.sqlservercentral.com/columnists/sindukuri/2797.asp
The source program (written in .NET) is calling a stored procedure in the source machine to write to the SSB queue. When we run SQL Trace, we find that the SP is responsible for 99% of the time taken. Here is our SP that send the message:
Declare @ConversationHandle uniqueidentifier
Begin Dialog @ConversationHandle
From Service SenderService
To Service 'ReceiverService'
On Contract SampleContract
WITH Encryption=off;
SEND
ON CONVERSATION @ConversationHandle
Message Type SenderMessageType
(<<XML String>>)
Please let us know if there are any additional settings required in the Service Broker to improve its performance. Or , what are the other approaches for building a distributed SSB application?

Distributed Transaction Between 2005 && 2000 Failing
Sep 19, 2007
Hi Folks,
I have been struggling with a problem for the last couple days now regarding MSTD and distributed transactions. The main issue is that 3 servers are each sitting in a different domain. Non of the domains trust each other.
As of yesterday, I could get all the SQL 2005 chatting to each other using MSDTC without a problem. However, I have a SQL 2000 box which refuses to work. A normal query across a linked server works fine. A distributed transaction will not work. This is the case from A to B and B to A.
I have tested with DTCPing and it says all is ok.
The error messages are:
SQL 2000 > SQL 2005
OLE DB provider "SQLNCLI" for linked server "T-ServerTServer" returned message "No transaction is active.".
Msg 7391, Level 16, State 2, Line 2
The operation could not be performed because OLE DB provider "SQLNCLI" for linked server "T-ServerTServer" was unable to begin a distributed transaction.
And the other way round:
[OLE/DB provider returned message: New transaction cannot enlist in the specified transaction coordinator. ]
OLE DB error trace [OLE/DB Provider 'SQLOLEDB' ITransactionJoin::JoinTransaction returned 0x8004d00a].
Msg 7391, Level 16, State 1, Line 2
The operation could not be performed because the OLE DB provider 'SQLOLEDB' was unable to begin a distributed transaction.
If watching the DTC monitor, it shows an active transaction then goes back to 0.
All instances are on a 4 node cluster with 3 nodes turned off for the testing.
I have run out of things to try. Most of the symptoms for the above messages are to do with DTC security, the Turn RPC Security Off reg hack. All instances and OS (W2K3) are the latest updates / patches.
As for the 3rd server, SQL 2005, it is happy to talk
Anybody got a gem which I can try?
Edit: Both SQL 2005 servers are x64 while the 2000 is x86
Cheers,
Crispin

Service Broker And .net Windows Service
Sep 26, 2007I 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...

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

Is SQl Service Broker What I Need??
May 16, 2007Hi,
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,
