Query Notification / Server Log Error Messages
Oct 11, 2007
Two days ago I discovered that the drive on our test SqlServer2005 was full. The current Error_log had 54+ Gb (yes Gb) of records. Not only did I delete the file I restarted SS and the server.
That afternoon, I discovered that the current log had 33,678 records! I believe 33,616 of the records came from a single run of my app and set of program events. Obviously I'm doing something wrong in my Query Notification implementation and testing. And yet, when I try to to deliberately trigger the phenomenon, I can not.
Here is the head of the exported log file; the two msgs (query dialog closed and cannot drop queue) alternate thousands and thousands of times form a single test run. What is going on?! Pls help!

Hi All
In Work , we created a Cache component that serves a large business application, we are subscribing to almost 200 queries , the component worked quite well in the first few months of the development, but lately i am getting notification events that contain "Error" in the SqlNotificationEventArgs of the event , the "Source" value is "Client".
I have no idea what might cause this error event , we are close to "go live" with our product and we cannot depend on the Query Notification mechanism until this problem is solved.
Can it be a DataBase problem? Application Problem?
Thanks in advance
Eden

I found in error log of my server is full of message like this
The query notification dialog on conversation handle '{9AD14600-28AD-DC11-9B36-000D5670268E}.' closed due to the following error: '<?xml version="1.0"?><Error xmlns="http://schemas.microsoft.com/SQL/ServiceBroker/Error"><Code>-8494</Code><Description>You do not have permission to access the service 'SqlQueryNotificationService-174a4df0-bac8-4a51-8564-28d750d7c11a'.</Description></Error>'.
any idea what could cause that?
thanks!

My database is logging frequent errors and I am unable to determine the cause. These errors appear to be related to the Service Broker. Below is the database log file after a database restart and attempted access to the database through a web application. The first error (bottom of the logfile) is error 28054. I have searched on this error code and have found nothing helpful. Any assistance or direction would be greatly appreciated.

I have been testing SQLDependency and I have a two questions;
1) When using a stored procedure to run the dependency query, using a "clean" procedure (containing nothing but a select statement), works fine. Adding try..catch (which is a part of our coding standards), results in the subscription firing immediately because of an invalid query. Is this by design? If so, how can I implement error handling.
2) How does SQLDependency handle SQL Server restarts?
I see two options:
a) The subscription is fired listing a server restart message in the related service broker queue, but as far as I can tell, SQLDependency has no way of handling these messages given the connection has been broken. (Establishing a new connection and dependency won€™t read the said messages).
b) The SQLDependency listener on the client raises an error for the connection being terminated. Can I relay on this event to recreate a connection and dependency?
Help will be appriciated

Hi All,
I was wondering if anybody knows where to get a complete list of SQL Server error messages. I am writing a stored procedure that scans SQL Server Logs for errors and if there are errors in the logs, I get paged.
Thanks.

Hi,
I am using Reporting services through web services using the SOAP API. The problem I am facing is for any errors that occur the messages are getting displayed more than once.
For example : while rendering a report(which takes a parameter) if the parameter is not passed the same error message is displayed thrice.
"This report requires a default or user-defined value for the report parameter 'Num_RP_1'. To run or subscribe to this report, you must provide a parameter value. ---> This report requires a default or user-defined value for the report parameter 'Num_RP_1'. To run or subscribe to this report, you must provide a parameter value. ---> This report requires a default or user-defined value for the report parameter 'Num_RP_1'. To run or subscribe to this report, you must provide a parameter value."
while calling listChildren() method if the folderpath passed is a non existing one then the same error message is displayed twice.
"The path of the item '/SomeNonExistantPath/' is not valid. The full path must be less than 260 characters long; other restrictions apply. If the report server is in native mode, the path must start with slash. ---> The path of the item '/SomeNonExistantPath/' is not valid. The full path must be less than 260 characters long; other restrictions apply. If the report server is in native mode, the path must start with slash."
1. Why some messages are displayed twice and some are displayed thrice ?
2. Is there any way to get the error message only once ?
Thanks in advance,

Hello,
I have installed Sp1 for Sql Server 2005
I also received "locked files" and "reboot required". These errors I can find on all forums and do not worry me anymore.
However i still would like to know more about the messages in the log files.
- What does this mean: "Failed to read associated hotfix build information for the following file"......
- What does this men: "Failed to read version information for the following file".........
- Why are some products NOT APPLIED, while in the other log file it says "SUCCES" for the same product?
These beneath the 2 log files.

I am getting a new server online at a customer, and our system shows very funny erorrs under full load. No explanations could be found. Anyone has some?
Here we go:
Server failed to resume the transaction, desc: 360000054a. The transaction active in this session has been committed or aborted by another session.,
at System.Data.SqlClient.SqlCommand.ExecuteNonQuery()
and
New request is not allowed to start because it should come with valid transaction descriptor.
System.Data.SqlClient.SqlException
I am a little lost on those. Simple fact is that I do not find any description of those. Anyone an idea what causes these?

Some T-SQL commands can fail with multiple errors. For example, if you try to disable a primary key constraint using ALTER TABLE t1 NOCHECK CONSTRAINT PK, you will get messages like:
Msg 11415, Level 16, State 1, Line 341
Object 'PK' cannot be disabled or enabled. This action applies only to foreign key and check constraints.
Msg 4916, Level 16, State 0, Line 341
Could not enable or disable the constraint. See previous errors.
However, in the code below, only the last message is printed. How can I print all the error messages?
USE tempdb;
CREATE TABLE #t1(c1 INT CONSTRAINT PK PRIMARY KEY);
BEGIN TRY
ALTER TABLE #t1 NOCHECK CONSTRAINT PK;
PRINT 'Primary key disabled'
END TRY
BEGIN CATCH
PRINT ERROR_MESSAGE();
END CATCH

I have a SQL2008 database, running Standard Edition 64-bit, database owns by sa, connected to Management Studio using Windows Authentication mode. When I tried to generate scripts from a database, I got the following error messages:-
[Operation is not valid due to the current state of the object. (SqlManagerUI)]
which happened at one particular table. I have reviewed this table definitions are normal, and I could select data from it.
I couldn't find any information anywhere relating to this error messages, except that someone got it when they were trying to change the authentication mode or sa password.

I'm developing a database-driven program using SQL server 2000 and Visual Basic 2005.
Most of the guys say professional programming is doing the validation stuff (such as the constraints and data integrity stuff like" [0-9][1] " and the use of LIKE IN keywords etc.) in the databse itself.
say i did the data validation contraints in SQL server itself. and now i connect the database with the interface made in 2005. and say a person enters some invalid data through the interface. but the error messages are generated by SQL server. how am i to display the SQL server generated error messages in the VB made interface??
PLS HELP ME .. if the question is not clear pls tell so that i can explain it further.

hi,
When SQL server notifies the application that the records in a table has changed, is there a way to know which record has changed from the application?
Let me give an eg.
Consider that we have a table customer. We have registered for a notfication for 2 customers, say Cust id 1 and Cust id 2. Now , when records for these two customers changes we get a notification. Is there a way in .Net by whihc we can get whihc customer has been modified?
Thanks
Man.

I've got an application that's using query notifications with a two-user setup (a user that starts the dependency running, and an application user that subscribes to it). I'm having problems getting the query notifications to go through however... according to the Profiler, when the application user does something that triggers a query notification, it causes this error:
This message could not be delivered because the user with ID [application user] in database ID [database] does not have permission to send to the service. Service name: SqlQueryNotificationService-[guid].
The problem is that [guid] is different each time, and there doesn't seem to be a generic "grant send on all services" statement, so I can't grant send on the particular service in question to the application user to get rid of the error. (If I grant db_owner to the application user, the problem goes away and everything works, but I'd rather not do that. The application user already has subscribe query notifications, receive on QueryNotificationErrorsQueue, and references on contract::...PostQueryNotification.)
Obviously I'm doing something wrong, but I am completely out of ideas and can't seem to find anything new to try. Any ideas? Thanks.

After having problems with SqlDependency logging an infinite number of errors I've rewritten my code to use SqlNotificationRequest instead. Now I have a different kind of cleanup problem and am looking for help.
My code registers to be notified when table data is changed. When the event triggers, it re-registers. It works fine. The problem comes when my subscribing program ends: it orphans the last subscription. When the program re-starts it subscribes as before, but now there are now two subscriptions (or three, or however many times my program is shut down). As an Admin I can run KILL QUERY NOTIFICATION SUBSCRIPTION ALL; I can even hard code this into my app as it is the only one (for now) using this instance of SS. But there must be a better way.
When I subscribe (.NET) how do I get the subscription id? Then I could just KILL that single id when my code shuts down. Specifically what code should I include in StopListener()? Thank you.
public void StartListener()
{
// starts a new thread whose sole purpose is to sleep until waked
Debug.WriteLine( "RequestNotification: StartListener" );
if( null == _listener )
{
_listener = new Thread( Listen );
_listener.Name = _threadName;
_listener.IsBackground = true; // essential!
_listener.Start();
}
}
public void StopListener()
{
Debug.WriteLine( "RequestNotification: StopListener" );
// not necessary, but good practice
_listener.Abort();
_listener = null;
Debug.WriteLine( "RequestNotification: Listener aborted..." );
}
private void Listen()
{
// infinite loop on this thread: keep listening even after
// receiving notification
while( true )
{
// connects to SqlServer queue and sleeps until a notification msg arrives
using( SqlConnection conn = new SqlConnection( _connect ) )
{
conn.Open();
Debug.WriteLine( "RequestNotification: Listen connection opened..." );
using( SqlCommand cmd = conn.CreateCommand() )
{
cmd.CommandText = "WAITFOR ( RECEIVE * FROM " + _queue + ");";
cmd.CommandTimeout = 0; // _notificationTimeout + 100;
try
{
// the thread is blocked until the waitfor event occurs.
SqlDataReader reader = cmd.ExecuteReader();
// the waitfor has triggered
while( reader.Read() )
{
// messageText = System.Text.ASCIIEncoding.ASCII.GetString( (byte[]) reader.GetValue( 13 ) ).ToString();
}
// and now we need to hand things back to the user's passed
// delegate, ensure we're back on the UI thread as well
//object[] args = { this, EventArgs.Empty };
Debug.WriteLine( "RequestNotification: Notification received." );
SqlNotificationEventArgs e = new SqlNotificationEventArgs( SqlNotificationType.Change, SqlNotificationInfo.AlreadyChanged, SqlNotificationSource.Database );
_delegate( this, e );
}
catch( SqlException )
{
// if the queue name doesn't match one in the db an exception will be thrown
throw;
}
}
}
}
}

Hello all,
We have encountered a weird problem; we have an application that registers to several queries for notification.
For several weeks everything worked fine, any change to any query result in the database triggered the notification event, but since yesterday the mystery began€¦ since yesterday not all changes triggers events , changing one table raise the notification event, changing the other doesn€™t , all seems fine in the database , the application reports that all queries were registered successfully , in the subscription view in the database we can see that all the queries that the application subscribed to are present€¦
What can be the problem? Is it something in the database? Can it be a problem in our application, please keep in mind that everything worked until yesterday€¦
Thanks,
Eden

Hi all,
I am looking at replacing a polled system with Query Notification. However when I create the SqlDependency I need to be sure I have the correct permissions. I check the SqlClientPermissions via the Demand() method, but also want to ensure I have the correct DB permission given my current connection string. As I understand it I need to have the following permissions:
CREATE PROCEDURE, QUEUE, and SERVICE permissions
SUBSCRIBE QUERY NOTIFICATIONS
SELECT on underlying tables
RECEIVE on QueryNotificationErrorsQueue
I check most of these via the 'has_perms_by_name' function, but cannot find the correct syntax to check for RECEIVE on QueryNotificationErrorsQueue. I would also love to find a way to do this via SMO instead of issuing SQl commands. Also am I missing any checks ....
Finally, I have also run into the problem whereby SQL issues the following error:
The activated proc [dbo].[SqlQueryNotificationStoredProcedure-1fd90369-7781-4bad-a1b7-e1b56e328374] running on queue ImlHostDB.dbo.SqlQueryNotificationService-1fd90369-7781-4bad-a1b7-e1b56e328374 output the following: 'Could not obtain information about Windows NT group/user 'EMEADyerN', error code 0x54b.'
I ran into this issue when I bought my machine out of sleep mode with it no longer connected to the network. Is their no way to get a error notification. In this situation I will just stop seeing notification and without looing at the ErrorLog believe their is nothing wrong.
Many Thanks, Nick

Hi Guys,
I'm having some problems setting up a SQL Server 2005 Query Notification application. I've only recently moved from SQL Server 2000 so 2005 is still a little alien to me!
I've followed example found on the internet in the following steps:
1.
ALTER DATABASE <dbname> SET ENABLE_BROKER
2.
GRANT CREATE PROCEDURE TO <user>
GRANT CREATE QUEUE TO <user>
GRANT CREATE SERVICE TO <user>
GRANT SUBSCRIBE QUERY NOTIFICATIONS TO <user>
GRANT RECEIVE ON QueryNotificationErrorsQueue TO <user>
3.
ALTER DATABASE <dbname> SET TRUSTWORTHY ON
The application developers have also followed the same example setting up SQL cache and the connection code. When they start the application I can see the connection in the activity monitor but it has a status of SUSPENDED. I've also checked the view:
SELECT * FROM sys.dm_qn_subscriptions
There are no subscriptions setup I can however see that there is a new SP created. I tried to creating master keys as well but I'm not sure what the reasoning behind this is.
Is there anything else I need to take into consideration or check? When I change the data which they use for their select statement SQL profiler doesn't register anything (except the update). I have however seen this:
exec sp_executesql N'END CONVERSATION @p1; BEGIN CONVERSATION TIMER (''69e2c786-9d33-dc11-a751-0050568146e8'') TIMEOUT = 120; WAITFOR(RECEIVE TOP (1) message_type_name,
conversation_handle, cast(message_body AS XML) as message_body from [SqlQueryNotificationService-5fb25d04-6ef6-47e6-9406-854f15e16eb7]), TIMEOUT @p2;',N'@p2 int,@p1
uniqueidentifier',@p2=60000,@p1='BD98F6B4-A133-DC11-A751-0050568146E8'
This occurs when they refresh the page.
Any ideas?
Cheers!
Ian

Dear,
I have designed a SiteMap provider for SQL Server. But I am worried about the notification service of SQL Server. My SiteMap requires service broker enabled in SQL Server. When I have web farm (multiple clustered server) does the Sql Server service broker notify all the web servers? Or, it notifies only the server request?
Have anubody implement such scenario? Looking forward for your reply.
Sincere Regards,Sultan

Hi All
We built a Cache component that take advantage of the SQL Server 2005 query notification mechanism, all went well , we tested the component in a console application , and notifications kept coming for as long time as the console application ran.
When we initiate our Cache Component in our web service global.asx application start event , the query notification works for a few minutes , but if we came after 10 minutes or so , we stoped getting notifications from sql, the SQL Server queue is empty , and all is showing that there is nothing wrong on the DB side...
Our Cache component is a Singleton class , that perform all registrations ,catch the notification events and resubscribe for notifications.
What can be the problem? is our Cache component object are being collected by GC?
Does IIS disposes the SQL Connection that the Query notification uses?
We are on a crisis...
Thanks in advance.

We are in development stage of an application which uses Query Notification feature of SQL Server 2005. When the development started what the development team did was, they just Enabled broker on the database by SET ENABLE_Broker statement and they started using Query Notification. Now the application is in testing phase and when we test with many user, the performance is really slow. What i want to know is , when we use Query Notification what all are the setting to be done at the database level. Is this setting enough. And also how can i tune this system. any useful link is appreciated.
thanks in advance

I'm using query notifications and it worked fine as long as I just edited the data that the "query points to" (one table). That is, my graphical represenation of the data (in a gridview) was updated correctly with the new data 1ms after I changed it, just like it should.
When I inserted a new row to the table the query notification stopped working, meaning my gridview wasn't updated. Any idea of why? Also, after this, not even editing of the data made the query notification trigger so it must have totally stopped.
Thanks in advance

The title says it all. You can do it from a ADO.Net client so why not from TSQL.
It all uses the service broker stuff so why not?

In order to avoid a large ammount of network traffic we decided to use Query Notification to Update our Clients.
Usually we have 20 up to 200 Clients connected to the DB, and some of the data QN is pointing at, are changed frequently (about 5 times per second) .
Now i heard it is recomended to connect just 10 Clients (max) to get acceptable performance out of SQL Server.
So my questions:
Is Query Notification the rigth technique to handle this kind of Data Changes.?
Is there an other feature or technique to get updated at client-side with less performance and ressource consumtion (without polling)?
Are there improvements in SQL-Server 2008?
How should the Server be configured to handle more than 10 Clients?
Thanks in advance

I have noticed something strange on the select statement that you can use on query notification.
I have a table that contains a compute column let's call it "Calculate".
If I subscribe to query notification:
Select ID from table
the subscription fails.
The column Calculate doesn't use the column ID.
Why??
for me it shouldn't be the case
Thankx
