If I have a stored procedure that is reading data in one database and writing it to another database (same instance) are there any extra grants that I must do. I do have a user created in both databases with the same certificate (backup and create certificate from the file system) and I've done the
GRANT AUTHENTICATE TO [SessionsServiceProcedureAudit];
GRANT EXECUTE ON <the cross database stored procedure>

If all my SQL Server instances are mutually trusted, am planning to implement transport layer security with Windows authentication. My query is that if I'm using Windows authentication do I need certificates to be created? Though I am using Transport security, I can achieve encryption by ENCRYPTION - ON in the Begin Dialogue conversation. I assume Message integrity using MD5 signatures are by default provided by Service broker irrespective of whichever service options we choose?
Can I have some article references on how these security mechanisms will impact the performace of Service broker communications?
Thanks a lot,
Just tried to deploy my service broker solution to a test environment but got the following error:
An exception occurred while enqueueing a message in the target queue. Error: 15517, State: 1. Cannot execute as the database principal because the principal "dbo" does not exist, this type of principal cannot be impersonated, or you do not have permission.
Any idea as to what this error message actually means and what I would have to do to get it to work?
Thanks
I am using windows authentication to send messages from one server to another.
The user is a domain user that is sysadmin on both servers and db owner of each database.
The errors I see in porfiler are as follows
At target,
An error occurred while receiving data: '10054(error not found)'.
and the following at the initiator:
Connection handshake failed. An OS call failed: (8009030c) 0x8009030c(The logon attempt failed). State 67.
For what its worth, the script for my target endpoint is below, and access has been granted to public:
CREATE ENDPOINT [BROKER]
AUTHORIZATION [MYDOMAINmssqlssb]
STATE=STARTED
AS TCP (LISTENER_PORT = 4022, LISTENER_IP = ALL)
FOR SERVICE_BROKER (MESSAGE_FORWARDING = DISABLED
, MESSAGE_FORWARD_SIZE = 10
, AUTHENTICATION = WINDOWS NEGOTIATE
, ENCRYPTION = REQUIRED ALGORITHM RC4)
I've actually used these users/objects successfully dozens of times on a seperate server with many clients...I am just re-scripting the objects here on this new server. The new remote machine is an image of one of the original machines that was working fine (with new broker GUIDs).
Thanks for any insight.

what is the difference between the Dialog security and the transport security?
If I disable the dialog security can the messages be sent to the a different SQL server instance. As the transport security will encrypt the messages.
If I don't create a certificate to be used by the transport security can the messages be sent to another SQL server instance?
Can a message be sent to another SQL Server instance without creating a REMOTE Service Binding?
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 all,
i m trying to send message between different server instance using service broker.
and for security purpose i am trying to create certificate. for that i have used makecert.exe and get a certificate and a private key. but when i am creating certificate using that file it is showing error
the code is --
CREATE CERTIFICATE ctfSourceServerMaster
FROM FILE = 'C:SourceServer.cer'
WITH PRIVATE KEY ( FILE = 'C:SourceServer.pvk', DECRYPTION BY PASSWORD = 'PrivateKeyPassword' )
ACTIVE FOR BEGIN_DIALOG = ON
GO
i have created the file SourceServer.cer' and SourceServer.pvk' by using makecert.exe tool.
the idea behind creating the certificate ctfSourceServerMaster is to give transport security.
I am running the particular script in the master database.
but still i am getting error
ERROR:----
The certificate, asymmetric key, or private key file does not exist or has invalid format.
If any body has any idea please help!!!!!!!!!!!
Thanks a lot in advance
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?

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

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...

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...

So SQLDependencies failed to do what I wanted them to do for my Cache Invalidating, so i'm going to humor another possibility for a half day - Triggers on my database table that communicate messages to my C# inside my ASP.NET App. Any advice on how to tap into a message queue with C#?

View 3 Replies View RelatedHi,
We have a customer whos database just grows and grows. Not the customers own tables, but the:
sys.sysconvgroup
sys.sysdesend
sys.sysdercv
And these tables are linked to the Service Broker, and according to http://msdn2.microsoft.com/en-us/library/ms179503.aspx these tables exists in every database and are used by the Service Broker.
Now to my questions =)
HOW do I delete rows from these tables? How come these tables hust grows and grows, could it be any setting in the SQL 2005 Server or is it the customer who has programmed his application wrong?
Please respond as soon as possible.

I'm in the process of doing the initial research for the architecture of a large scale, transactional messages routing platform.
My initial
design called for a series of MSMQ queues and Windows Services, written
in C#, to process the messages in these queues. There will be incoming
and outgoing queues, queues to store unroutable messages, etc.
My
application will be routing many hundreds of thousands (and eventually
millions) of messages per day. These message are very small (< 200
bytes each) and must be routed very quickly. (<1 second processing overhead per message for high priority messages.)
Using the term
"routing" may be a bit misleading. The messages arrive via TCP socket
connections. I will just need to take in a message, examine its
intended destination, and send it to one of several outgoing socket
connections, likely on different machines. Some messages require higher priority routing than others,
but I don't need multi-hop routing or anything like that.
Of
great concern to me is that there are absolutely no single points of
failure in the system. Because of this I was considering using a combination of MSMQ and Windows Services in a Clustered environment.
Can the Service Broker provide me with this kind of functionality? If so, how well does it perform and scale? Is it a better choice for messaging applications that require high transactional throughput than MSMQ?
I'm just trying to get an idea of what products/services I should look into further.

I am new to service broker and would like a little help please. I have a SP which gathers information from a collection of tables. Depending on the data gathered it may or may not begin a dialog conversation with a service broker queue.

Hi, in the development env. I created the 2 dbs used by service brokers, the service brokers objects (messages, queues etc...).
The schema applied to tables and Activation SP is [dbo] and also the queues are executed as [dbo].
Everything works fine!Cool!
Now that we have to deploy evertything on production I would like that the service broker conversation runs using a specif user ( in this way when I log the Service Broker's errot in the event log I see this specific user and not my name)
Which kind of permission I have to give to this the user .. it is enought that I assign to it the schema DBO or I have to change the definition of my queues( execute as '[dbo]') or to create a new schema?
Thankx everybody fo any help!
