Hi,
I'm looking to run a "job" on a SQL database regularly (like scheduled by a "task scheduler") to updated my database.
It appears I can use SQL Service broker to run such a job.
Can I embed a "task scheduler" inside my SQL Server database to trigger this job each X seconds?
Hi, I have read that service broker can be used to manage and schedule jobs. but how is this more of an advantage compared to the current sql server job scheduling using the sql server agent. thanks in advance. Would appreciate if somebody can answer immediately

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,

Hi,
I'm developing an Ads system, which will have an scheduler functionality. Here's how it works: each hour a process will verify and publish an XML file with Ads that have to be shown at that hour. To display the Ad, the "NextDisplay" table's field has to be equal to currently date/HOUR. Then the process will update the "LastDisplay" field with the currently time and call a MsSQL stored procedure that will recalculate the NextDisplay time of the Ad.
My problem is doing this stored procedure. I've based my tables to allow the same schedule rules of the Windows Task Scheduler, so I have to verify each rule to calculate the next display time, but it's a difficult process, 'cause there are a lot of details to be considered.
I thought interoping with Windows Task Scheduler or seeing some code that do something like that, to have some ideas about how to implement it.
Suggestions?
Thx!

I use the Task-Scheduler from SQL-SERVER 6.5 to backup and maintain databases. Have you any idea how I can clear the history automatically. I want to clear the history-logs older then 30 days and for 25 SQL-Server is it very costly to delete the history manually. Thanks.

Hello,
I had configured a backup operation with SQL Server Express 2005 and saved the operation as a .sql file. I then configured a task with Task Scheduler to execute this .sql file at a specified time. The text in the Run box for this task is:
"C:Program FilesMicrosoft SQL Server90ToolsBinnSQLCMD.EXE" -S .SQLEXPRESS -i"C:Program FilesMicrosoft SQL ServerFull_M-Th.sql"
I verified this .sql file would run a backup by launching Management Studio Express, opening the file, and then clicking the Execute button. Minutes later, I had a backup. Yet the scheduled task did not run, nor would it run when I manually chose to run it from the list of scheduled tasks. I looked in the Event Viewer, but could not find anything that tipped me off to what I am not doing correctly. If anyone can tell me what might be wrong with the command I pasted above, it would be appreciated.
Thanks for reading!
This is my sql script :
DECLARE @countRows INT,
@currDate DATE,
@checkForTasks INT,
@created_by_id INT,
@gst_ID int;
SET @currDate = Getdate()
This is resided in videos folder of windows , i have created a task schedular in windows 8.1 to run daily at every 10 seconds , but it is not working ...
This sql query is running perfectly in sql server. Query have no errors.
I am new to the world of ETL. I recently started using SSIS and I have come across couple of questions on this.
1.Can we run a SSIS Package using windows task scheduler?
2. If the above answer is yes,I don't have the SSMS installed on my machine. Can a SSIS package run in the absence of SSMS?(I do have Visual studio and SQL server data tools installed)
3. Can a SSIS Package run in the absence of Visual studio and SQL Server Data Tools.Say for example, I create a SSIS package and then remove Visual studio and SQL server data tools from my machine. Will the Task scheduler still be able to run the SSIS package?
4. Does the SSMS free edition comes along with SQL server Agent?
Hi all,
I am trying to setup the cluster SQL server, say ServerA and ServerB. While I start the setup in ServerA, it prompts,
'Setup failed to start on the remote machine. Check the Task scheduler event
log on the remote machine.'
But I found that there is no remote logon to both nodes and the service task scheduler is running in both node.
On the other hand, I try to install the SQL via ServerB, it prompts for valid Native client package 'sqlncli.msi' and caused the setup failed finally. However, the Native client was setup successfully as a prerequisite once starting the setup.
Any advise? Thanks in advance!!
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,
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#? I'm thinking that my messages could be 1 of about 100 different strings as far as what occurred on the Database Tables

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.

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!
