At my company, we're trying to use service broker to create a client-server system where there is a head office machine and multiple outlets registered with that head office. My problem is that sometimes when a branch sends a message to the head office, it just seems to sit in the transmission queue and never gets sent. If I run a script that forcibly ends the conversations on the client machine (with cleanup), storing the message bodies and then resend them, they seem to get through fine.
The way that we send messages is by calling a t-sql stored procedure from a c# application using SqlCommand (don't know if this should make any difference).
If I monitor the Head Office machine and one of the Outlets while this is happening, on the HO I get three events in a row:
Broker: Message Classify (1 - Local)
Audit Broker Conversation (2 - No Certificate)
Broker: Message Undeliverable (1 - Sequenced Message)
The TextData contained in the third event is: This message could not be delivered because the security context could not be retrieved.
The RoleName of the server is Initiator, and the TargetUserName is the name of the service on the Outlet.
On the Outlet I get the following event repeatedly (presumably as it continues to try sending the message) - Broker: Remote Message Acknowledgement (1 - Message With Acknowledgement Sent).
On the client the RoleName also appears to be Initiator, and the TargetUserName is blank.
This would make me suspect that certificates were missing or something, except that if I remove messages from the queue and resend them they seem to get through, and also I've checked both databases and they have the correct certificates.
We are having a problem with messages getting out of transmission_queue and into the queues themselves. The queues all are actviated and enabled, and our service broker is enabled at the database level. The dba detached & reattached the db yesterday, which I believe may be the cause of this problem. Everything seems to be in order (sp ownership, activation procs, etc), except when I run:
select [name], count(*)
from sys.dm_broker_queue_monitors qm
inner join sys.service_queues sq on qm.queue_id = sq.object_id
group by [name]
I get 2 entries for each queue. And the last_activated_time is the same date as the detach event. When we reattached we had to do an alter database set enable_broker in order to get it back up and running. When I run the above query on our dev and test environments, I get only one entry per queue.
Does anyone know why this would happen? Is this a valid state for SB? And to get past it, if we can't figure out the real fix for it, we want to get a copy of all the messages in the transmission queue, do an alter database set new_broker, then replay them all into SB. We hope this fixes the root cause, but it's a guess.
Sorry for the stupid question, but I can't seem to figure it out...
There are 119 messages that are stuck in the transmission queue, all for the same queue. When I check the status of the queue (via sys.service_queues), is_receive_enabled = 1, is_activation_enabled = 1, and max_readers = 3. When I check to see if there is an active queue monitor (via sys.dm_broker_queue_monitors) there is nobody watching this queue. What would cause this queue to be active, enabled but have nobody montioring it? Is there something internal that went wrong that made these (outbound) messages get stuck in the transmission queue, and is not showing up in the views? How can I get these messages "un-stuck" and flow through the system?
A problem I am seeing is the return message to this queue (to signify the target has consumed the message, and to end the conversation) are not being consumed, thus getting stuck in the "DI" state.
For some reason the messages are stuck at sys.transmission_queue. The transmission status seems to be null. I verified all the Queues and they hae the values of (is_receive_enables = 1, is_enqueue_enabled = 1, is_activation_enabled = 0)
I have set up the service broker on different domain and have bidirectional ports open to receive messages.
I can send and receive messages, when I run the same service broker setup scripts at the machines that belongs to same domain .
I may have a misunderstanding of how SB works, but this seems like a problem.
If a queue is disable (i.e. status = off) and a message is sent to the queue the message is placed on the sys.transmission_queue. Once the queue is enabled I thought the messages were sent to the queue in the order they were placed on the sys.tranmission_queue? I have been troubleshooting a problem and this is not the case. Do I have a misunderstanding of how the sys.transmission_queue works?
I've got 2 service broker databases on remote servers. I've created my endpoints, my routes and have everything set up. But when i send a test message, the messages set in the transmission_queue. There is no transmission_status. And when i look in at the sys.conversation_endpoints view I see that the conversation status is conversing. One odd thing I wanted to point out though is that the far_broker_instance column of the sys.conversation_enpoints view is null. When i run a trace on both databases, I see activity on the Initiator with things like Started_OutBound and conversing but I don't see any messages such as acknowledgment or any errors. On the Targer side I see no activity at all. Does anyone know what the deal is. Why don't I get some kind of error message. Why are all my messages staying in the transmission_queue?
I set-up my Service Broker comunication on the same SQL Server Instance beetween 2 different DBs.
One DB behave as Initiator and send messages to the SB service setup in the other DB.
I execute the SEND statement from the Initiator and if I count the messages on the sys.transmission_queue before to commit the transaction the count returns 0.
If I try to send a message not compliant with the message type, the count that runs after the SEND returns 1 - far enought.
I'm confused about the first behaviour because from what I understood the Acknolodgment and the removal of the message from the sys.trasmission queue should happen after the COMMIT.
I have a strange problem with messages getting stuck in a transmission queue. The set up is as follows:
1. Client database behind physical firewall 2. Firewall rules forward inbound traffic to Client Database 3. Server database has route to firewall 4. Client and Server databases on different physical networks
Over the last couple of days, the IP address of the PC that has the Client database on it changed. Messages were getting through to the Server from the Client but not the other way round. I presume this also meant that message acknowledgements were also not getting back to the Client because messages were stuck in the Client transmission queue.
Looking in more detail at the queued messages at the Server side, it appeared that the Server had received the messages, processed them, and sent back an end conversation. The state of the conversation in conversation_endpoints was DISCONNECTED OUTBOUND. Which I assume means that these would never get through to the Client?
What is the correct way of dealing with this situation? I tried doing an end conversation with cleanup at the Server end but this is clearly wrong because this removes any trace of the conversation from the Server and means that the messages now get through correclty (again) and processed (again). Meaning that we now have duplicate messages in our database.
1. drop receiver side service broker with sql command : drop service [//TyMetrix360Audit/DataWriter]
2. send a message from the sender.
3. now the sys.transmission_queue on the sender keeps the message.
The relevant tables on the sender and receiver no look like this:
the following summarizes the transmission queue on the SENDER:
conversation handle message_body transmission status 5A0F1D1F-449C-DC11-8EED-0002B3D9F7B5 my message in binary, ie 0x.F4E1.... <blank>
the following summarizes the sys.conversation_endpoints on the SENDER:
conversation handle conversation_id state 5A0F1D1F-449C-DC11-8EED-0002B3D9F7B5 461891C8-5D53-4D89-A7C6-097FE2EDB22A CO
the following summarizes the transmission queue on the RECEIVER:
conversation handle message_body transmission status 5A0F1D1F-449C-DC11-8EED-0002B3D9F7B5 message body of error message...... One or more messages could not be delivered to the local service targeted by this dialog.
the following summarizes the sys.conversation_endpoints on the RECEIVER:
conversation handle conversation_id state 5A0F1D1F-449C-DC11-8EED-0002B3D9F7B5 461891C8-5D53-4D89-A7C6-097FE2EDB22A DO
What do I do now?
There is a message stuck in the sender transmission queue. You responded in my last post that I need to do a RECIEVE on the sender and end the conversation myself? This is not helping me. I am still confused about the answer to this. Can you provide some sort of code outline or steps to resolve this issue. As of now I do not know how to resend my messages stuck in the sender transmission queue and they can not be lost when the conversation is ended.
Also, I thought SQL Service broker was supposed to hadle things like this. It is common for the receiver to not be there. In this case the messages should resend automatically once the receiver is back up. Please help as there is no documentation online about how to resolve this issue and your last response was not adequate.
I have seen this buried deep with the questions on Service Broker, but I am looking for it again. How do you delete all records from your sys.Transmission_Queue. This is on a test server and I want to clean it before some more test.
Are lock hints propagated to the underlying tables of system catolog views? I ask because I often query sys.transmission_queue with nolock, and I wanted to know if this was honoured through out the underlying tables.
Secondly, is sys.transmission_queue indexed at all, providing a way to prevent table-scanning?
Is there any thought going into moving these two tables to a file group that we can control? Putting this in Primary with the rest of my system tables is quite problematic, and hinders my ability to manage space usage on my files. Traditionally, we didn't have to consider a primary file group that could grow to large proportions, but now with these two tables it can. If a large volume of messages gets sent through and the system can't keep up, then these tables and my primary file group will grow sometimes enormously.
as Christopher Yager say in "Need distributed service broker sample", I also test sending messages between two SQL Server 2005 instances,and after I setup the test environment with instance1 and instance2,I find queue [q2] in ssb2 can't receive message from ssb1. when I query by "select * from sys.transmission_queue",I get some message records that transmission_status is "64(error not found)".
Hi was wondering whether it is possible to log somewhere outside SB that there are messages in the transmission_queue because the Target queue was disabled.
I was testing this scenario:
try to send messages on a disabled queue and log the problem.
But the transmission_status from the trasmission_queue is always empty.
This is the code that I tried to execute between the send and the commit and after the commit:
WHILE (1=1)
BEGIN
BEGIN DIALOG CONVERSATION .....
SEND ON CONVERSATION ......
if select count(*) from sys.transmission_queue <> 0 BEGIN
set @transmission_status = (select transmission_status from sys.transmission_queue where conversation_handle=@dialog_handle);
if @transmission_status = ''
--Successful send - Exit the LOOP
BEGIN
UPDATE Mytable set isReceivedSuccessfully = 1 where ID = @IDMessageXML;
BREAK;
END
ELSE
raiserror(@transmission_status,1,1) with log;
END
ELSE
BEGIN
UPDATE [dbo].[tblDumpMsg] set isReceivedSuccessfully = 1 where ID = @IDMessageXML;
BREAK;
END
END
COMMIT TRANSACTION;
As I wrote before the @transmission_status variable is always empty and I have the same result even if I put the code after the commit transaction!
Maybe what I'm trying to reach has no sense?
With the event notification I can notify when the queue is disable because the receive rollsback 5 times but what if by mistake the target queue is disabled outside the SB environment? I can I catch it and handle it properly?
I have spent days searching the web and forums for an answer to this simple question and cannot find an example.
I have built a service broker application on sql server 2005. The application puts some xml on an incoming queue which is basically a few parameters to be used in a query. This queue will then call a stored proc which does some business logic and puts the resulting results in another queue also in xml.
I have written a test harness in SQL to put messages on the inbound queue and then some sql to retrieve the returned code from the outbound queue.
What I want to do is be able to convert the SQL which does this into .net code to be used by an application. i.e. write in .net some code to put xml on a queue and then write some .net code to retrieve xml from another queue.
I wouldn't have thought this would be a difficult thing to do and would have been done hundreds of times, but unable to find anything to simply send and retrieve XML to service broker queues....
thanks for your help.. its really needed. I found some links, but they are really vague and often doing select statments in service broker or something like this. I don't want to call any sql, just send and recieve XML on the queues.
any example code that does this, would be really helpfull
Ok I have created a 2005 sql advanced database with text indexing. I have create the database like so created a new database with text indexing enabled and the following table create table support (problemId VARCHAR(50) NOT NULL PRIMARY KEY, problemTitle varchar(50) NOT NULL, problemBody text NOT NULL, linkOne varchar(50), linkTwo varchar(50), linkThree varchar(50), linkFour varchar(50), ftid int NOT NULL) next create fulltext catalog remoteSupportCatalog create unique index ui_remotesupport ON support (ftid) then create fulltext index on support(problemBody)key index PK__support__7C8480AE on remoteSupportCatalog -------- I then populated some rows and issues a quesry Select * from support where freetext(problemBody, 'test database') it works pulls back all the data I expected it to pull back
In my asp page I created a database connection with the folling select command <asp:SqlDataSource ID="SqlDataSource1" runat="server" ConnectionString="<%$ ConnectionStrings:rsdb2ConnectionString2 %>" SelectCommand="SELECT * FROM support WHERE FREETEXT(problemBody, @srchBox)">
created the search parameter<SelectParameters> <asp:ControlParameter ControlID="srchBox" PropertyName="Text" Type="String" Name="srchBox" /> //this is a text box that is searchable with a button </SelectParameters> and it doesnt give me back an error or data it does nothing. What am I missing?????
I hate making complecated queries....but this doesn't seem too hard and I cannot figure out where my error is. The message is "Incorrect syntax near the keyword 'FROM'."
The query is: SELECT tblUsers.lUserID GROUP BY tblUsers.lUserID HAVING Count(tblDLHistory.lDownloadID) = 0 FROM tblUsers LEFT JOIN tblDLHistory ON tblUsers.lUserID = tblDLHistory.lUserID WHERE tblDLHistory.lVersionID = 5
I need to search the database and pull up all customers who have a 'device' and their email address. I have watered down my select statement, but the following is the basics of it. I just cannot figure out how to also append the email. I have tried many different attempts and have come up dry.
Select a.company From dbo.contact1 as a, ( Select DISTINCT accountno From dbo.contsupp Where contact LIKE 'Product Inventory' AND contsupref LIKE '%device%' ) as b Where a.accountno = b.accountno
Below are some sample databases to get an idea of some possibilities. There will not always be an entry in dbo.contsupp for an email address. There will not always be an entry in dbo.contsupp for a device.
I have a small table to manage orders in my company. When a new order is entered, the script makes use of the last row of the table to find out the last order, increments it and creates the new order number. The problem is, a few days ago the last row got stuck. New insertions to the table all got the same order number and are placed above the last row. Anybody has any idea what's going on?
Heres is a shorten downed example of what I am trying to achieve. I have four tables. The first being OrderHeader, the second OrderLines, the third StockCategory. The OrderHeader table contains basic order details, which in turn is linked to the OrderLines table which show if the order in the OrderHeader has a single or multiple order lines. The StockCategory table shows what stock group the item in each order line is associated to.
Here is an example of the tables in a shorten downed version (in both data and fields):
OrderHeader: Sales Order Ref, Order Date, 1, 01/05/2008 2, 01/05/2008 3, 02/05/2008 4, 02/05/2008
OrderLines: Sales Order Ref, Part Number 1, 222 1, 234 1, 333 2, 222 2, 555 2, 444 3, 333 3, 111 4, 222
StockCategory
Stock Category, Part Number, A, 222 B, 234 C, 333 D, 444 E, 111
The thing I am trying to do is assign each of the orders to a Stock Group which I can do. The thing that has baffled me is if an two of the order lines in one order are assigned to different stock groups. If this occurs I want to assign the order to the order to the stock group with the highest priority (1 being highest, 3 being lowest) for example if one order line in the order was assigned to Berr (priority 1) and the other to DFID (priority 3) the order would be assigned to Berr.
SELECT @BeginDate = [BeginDate] FROM DatePeriods AS dp WHERE dp.ID = @Period SELECT @EndDate = [EndDate] FROM DatePeriods AS dp WHERE dp.ID = @Period
SELECT COUNT(oh.[Sales Order Reference]) FROM dbo.OrderHeaders AS oh LEFT JOIN dbo.OrderLines AS ol ON oh.[Sales Order Reference] = ol.[Sales Order Reference] LEFT JOIN dbo.StockCategories AS sc ON ol.[Part Number] = sc.[Part Number] WHERE oh.[Order Date] BETWEEN @BeginDate AND @EndDate AND sc.[Stock Group] IN (SELECT sg.[Stock Group] FROM dbo.StockGroup AS sg WHERE sg.[ID] = 'Berr') AND ol.[Sales Order Reference] NOT IN (SELECT col.[Sales Order Reference] FROM dbo.CancelledOrderLines AS col WHERE col.[Part Number] = ol.[Part Number])

Sorry for all the code below. I am realizing that my DB design is bad but I already have 7 pages built around it that work fine...until now, so I would really like to not change the DB if possible. My table has 22 columns: iID which is the identity colum. Then there is iAsmtID which is the assessment ID. Lastly there are 20 colums- q1 through q20, each of which will have a 1, 2, or 3, depending on the radio buttons the user clicked. Nows my problem. I have to find a percent for the assessment. It works like this. 3s are NA so we are not worried about them now. I need to find the number of ones and the number of twos for each assessment ID. Then add those together and divide by the number of ones. How can I find the number of the ones and twos. I have below but its not working.

I have a job that extracts data from 10 different tables to 10 diffrenet tables of MS-Access (.mdb file). The job ran okay since last one month but yesterday it ran and did not stop at all .Status is shown as "Executing" .. I tried to stop it but it is not stopping . I tried to kill associated process (spid) but it allows me to kill spid but it shows there running.
Any idea why it is happening ?

I have a sql problem I'm trying to solve. I'm selecting from a table based on a foreign key, and the select returns 2 rows. The table has a column called type, and each row for the foreign key has a different type value. Hopefully the example below can help to explain:
Case 1:
PK | FK | Type | Text -------------------------- 1 | 226 | 0 | some text goes here 2 | 226 | 1 | NULL
Case 2:
PK | FK | Type | Text -------------------------- 3 | 334 | 0 | some text goes here 4 | 334 | 1 | actual text I want to select is in this cell
I'm trying to create a select statement to grab the text for the foreign key I'm looking up. In case 2, I want the text where type=1 but in case 1 I want the text where type=0.
I had started writing it as
select text from table where fk=334 and ( (type=4 and text is not null) or type=0 )
but this returns both rows. What I what is something that I think is more akin to
case a || case b
expression in programming - if case a evaluates as true, use that, otherwise evaluate case b and use if true, otherwise return false.
I hope you can understand what I'm trying to get and any suggestions would be much appreciated.
Everything works except for the select portion, I cant put my finger on what is wrong with this.. I included the trigger and error.. If one can show what I did wrong that would be great..Thanx..
