Recovery :: Operator Does Not Receive Notification
May 18, 2015
alert fires, but the responsible operator does not receive notification.We area using this alert from past few months. But last week got an TempDB full and we found the error in SQL server 2012 error log. But we didn't get notification to email.But the email id is working fine because we are using same email id for all other alerts.
I am looking for the best way to get notifications if DBCC CHECKDB indicates an error on a database it checks. So lets say I create a maintenance plan that runs CHECKDB at 2AM for all user databases. What is the best method to get notifications that the command reported issues on one of the databases?
We have a requirement to build SQL environment which will give us local high availability and disaster recovery to second site. We have two sites- Site A & Site B. We are planning to have two nodes at Site A and 2 nodes at Site B. All four nodes will be part of same Windows failover cluster. We will build two SQL Cluster, InstanceA will be clustered between the nodes at Site A Server and InstanceB will be clustered between the nodes at Site B, we will enable Always On Between the InstanceA and InstanceB and will be primary owner where data will be written on InstanceA and will be replicated to InstaceB. URL....Now we want we will have instanceC on the Site B and data will be writen from the application available on Site B, will be replicated to the instance on the Site A as replica.
Pages on a full recovery model database corrupted, need to ensure data loss is minimal for restore operation am thinking about restoring the latest full backup.
in the process of migrating a big db from server 1 to server 2, we had to roll back the change. I started with taking a full db backup and restoring it on server 2 with norecovery, and then a couple logs with norecovery, and then the last log with recovery.
Is there some way to continue this chain now, I mean to change the db to norecovery, or other way to restore logs.
I dont want to do a new full backup.
If I try to do a log restore now i get the message:
Msg 3117, Level 16, State 4, Line 1
The log or differential backup cannot be restored because no files are ready to rollforward.
We have 3 replica AG setup. 2 replicas are in sync/automatic failover, the other(DR Server, different subnet) in asynchronous/manual mode…All these replicas were on sql server 2012, Recently we upgraded DR server to 2014. Since then we have a problem, the AG databases in 2014 instance went into ‘Synchronizing/ in recovery’ state…The SQL server error log has message, the recovery couldn’t start for the database ‘XYZ’…We tried to create a new database and add it to AG , it works for fine for other two 2012 replicas, but on 2014 we see the same issue
We have an issue with a 3 node SQL 2012 Always on availability group. Normal operation is node 1 (primary replica) with node 2 and node 3 as secondary replicas.After some patching, SQL wasn't running on node 1 hence the AG flipped over to node 2. This went unnoticed for some time and the transaction log for one of the AG databases became full on node 2 and node 3. (I think this is because it couldn't commit the transactions on node 1 so couldn't truncate it's t-log?) The DB is using synchronous replication btw.So I started SQL on node 1 and flipped the AG back to node 1 (with a data loss warning but I accepted this).Now the issue is that on node 2 and 3, the DB in question is stuck in a "Reverting / In Recovery" State. I've tried various commands such as ALTER DATABASE SET ONLINE, RESTORE DATABASE WITH RECOVERY etc but these fail stating unable to obtain a lock on the DB.
The weird thing is that on node 1 the state of the DB is "synchronised".how to resolve this issue on node 2 and 3? I've left them overnight (in case they were rolling back transactions, the DB is fairly large) but nothing seems to have happened. remove the DB from the AG in node 2 and 3 and add it back in again, ie recreate the replication?
In working through some examples, sometimes I will see this pattern for receiving messages: What is the purpose of the "nested" WAITFOR (RECEIVE? What is this actually doing? Is it receiving the same message in both RECEIVE?
WAITFOR ( RECEIVE @dh = [conversation_handle], @message_type = [message_type_name], @message_body = CAST([message_body] AS NVARCHAR(4000)) FROM [Queue]), TIMEOUT 1000; WHILE @dh IS NOT NULL BEGIN IF @message_type = N'http://schemas.microsoft.com/SQL/ServiceBroker/Error' BEGIN RAISERROR (N'Received error %s from service [Target]', 10, 1, @message_body) WITH LOG; END END CONVERSATION @dh; COMMIT; SELECT @dh = NULL; BEGIN TRANSACTION; WAITFOR ( RECEIVE @dh = [conversation_handle], @message_type = [message_type_name], @message_body = CAST([message_body] AS NVARCHAR(4000)) FROM [Queue]), TIMEOUT 1000; END COMMIT;
Other times I will see this pattern for receiving messages: Why do a RECEIVE TOP(1) instead of just a RECEIVE?
WAITFOR(RECEIVE TOP(1)
@conversationHandle = conversation_handle,
@messageTypeName = message_type_name,
@messageBody = message_body
FROM [Queue]), TIMEOUT 1000;
And other times I will see this pattern for receiving messages: What is the purpose of RECEIVING into an in-memory table when you can just process the message directly?
WAITFOR(RECEIVE
queuing_order,
conversation_handle,
message_type_name,
message_body
FROM [Queue]
INTO @tableMessages), TIMEOUT 1000;
IF (@@ROWCOUNT = 0)
BEGIN
COMMIT;
BREAK; END
What is the difference between the three approaches from an architectural and performance perspective? I need to process messages as fast as possible and I'm not sure why or when each should be used. Also, does the timeout have any impact on how FAST messages will be processed, or is it exactly what it says - a timeout - if a message is not found within the period then the procedure will break?
I am trying to set up a stored procedure to retrieve to 20 messages from a queue into a table to implement a batched process. I have the following code in a stored procedure.
WAITFOR ( RECEIVE top (20) -- get batched so that we can process same listid once message_type_name, message_body, -- the message contents conversation_handle -- the identifier of the dialog this message was received on FROM dbo.target into @PayloadData ), TIMEOUT 3000 -- if the queue is empty for three second, give UPDATE and go away
However, the stored procedure is only retrieving 1 message at a time from the queue. Did I miss some other setting
If you are doing a disaster recovery of an entire SQL 2005 cluster, can you just install SQL server and restore the system database to get the configuration?
Hello Guys, I really need you help to debug this query. OBJECTIVE:THE QUERY SHOULD GIVE ME THE FIELDS I MENTIONED IN THE FIRST QUERY WITH THE CONDITIONS BELOW. CONDITION 1: RateReview field should have yesterday's date CONDITION 2: Email will be send to customer only once so Customer_GUID is UniqueIdentifier CONDITION 3: Customer shouldnt' have opted to get out from receiving any email so Termination field should be NULL ONe Customer can have many transwactions Is there any way i write the code specifying that no email should be sent more than once evereven if customer buys 10 tickets. Only one email sent so i need to specify that if this email has gone to particulare CUSTOMER_GUID then Ignore that record and do not send any email. This would be done by some tool known as StrongMail.
SELECT CAST(a.Transaction_GUID AS varchar(36)) as Transaction_GUID, CAST(a.Customer_GUID AS varchar(36)) as Customer_GUID, Film_id as MovieId, First_nm as FirstName, Last_nm as LastName, Email_nm as EmailAddress,
from ( select MIN(CAST(customer_guid AS varchar(36))) as Customer_GUID, Transaction_GUID from tblTransaction (nolock) where RateReview_dm > DATEADD(dd,-1,GETDATE()) and RateReview_dm < GETDATE()
and Terminate_dm is null and customer_guid not in ( select CAST(customer_guid AS varchar(36)) as Customer_GUID from tblTransaction (nolock) where RateReview_dm > DATEADD(dd,-1,GETDATE()) and RateReview_dm < GETDATE()
and Terminate_dm is null ) group by transaction_guid, customer_guid )z inner jointblTransaction a onz.Transaction_GUID = a.Transaction_GUID
Hai ,I created a table with primary key clustered. I have entered the datathru E.Manager . If a close the table and open it again , Ii shows therows with the (default) ascending order. Is, there any way to get therows in the user entered order(neither asc or dec order)With ThanksRaghu
I built a system where I am sending batches of messages using a single conversation. I want to pull these messages out of my queue using Service Broker. I may have more than one batch sitting in the queue waiting to be picked up, so....
In my SSIS package i started by getting a unique list of conversation_handles where the message type is my end of batch message ( should only be one per batch). Then I used the foreach loop construct thinking I could pass the conversation_handles around and into the data flow.
In the data flow I want to pull all of the messages at once. It looks like the receive statement is designed to do this with the concept of using a table variable.
So I built this SQL to use in for the SQL Command of my OLE DB Source. It gives me this error "Syntax error, permission violation, or other nonspecific errorr"
select top 1 @ch = conversation_handle from dm.[consultant queue] where message_type_name = 'BatchEnd' order by queuing_order;
-- select conversation_handle, message_type_name, message_body receive conversation_handle, message_type_name, message_body from dm.[consultant queue] into @messages where conversation_handle = @ch
select conversation_handle, message_type_name, message_body from @messages
I have tried sneaking the parameter into the SQL in other ways, but always get the same I have tried sneaking the parameter into the SQL in other ways, but always get the same error message. It just seems that SSIS, or OLE DB, don't want to pass parameters into a block of SQL that is executing this receive command. Has anyone else done something similar to what I am doing here? Any ideas on how to resolve this?
Obviously by using SSIS I want to work on the whole batch at once and not iterate message by message. Right now I just don't like the idea that I am getting the conversation_handle twice and possibly getting a different batch of messages to process.
I followed an example using the AdventureWorks database to set up a simple messaging test on one database:
Code Block -- We will use adventure works as the sample database USE AdventureWorks GO -- First, we need to create a message type. Note that our message type is -- very simple and allowed any type of content CREATE MESSAGE TYPE JobRequest VALIDATION = NONE GO -- Once the message type has been created, we need to create a contract -- that specifies who can send what types of messages CREATE CONTRACT JobRequestor (JobRequest SENT BY INITIATOR) GO -- The communication is between two endpoints. Thus, we need two queues to -- hold messages CREATE QUEUE RequestorQueue CREATE QUEUE ReceiverQueue GO -- Create the required services and bind them to be above created queues CREATE SERVICE Requestor ON QUEUE RequestorQueue CREATE SERVICE Receiver ON QUEUE ReceiverQueue (JobRequestor) GO -- At this point, we can begin the conversation between the two services by -- sending messages DECLARE @conversationHandle UNIQUEIDENTIFIER DECLARE @message NVARCHAR(100) BEGIN BEGIN TRANSACTION; BEGIN DIALOG @conversationHandle FROM SERVICE Requestor TO SERVICE 'Receiver' ON CONTRACT JobRequestor WITH ENCRYPTION=OFF, LIFETIME= 600; -- Send a message on the conversation SET @message = N'Hello, World'; SEND ON CONVERSATION @conversationHandle MESSAGE TYPE JobRequest (@message) COMMIT TRANSACTION END GO -- Receive a message from the queue RECEIVE CONVERT(NVARCHAR(max), message_body) AS message FROM ReceiverQueue -- Cleanup DROP SERVICE Sender DROP SERVICE Receiver DROP QUEUE SenderQueue DROP QUEUE ReceiverQueue DROP CONTRACT HelloContract DROP MESSAGE TYPE HelloMessage GO
This all works fine but if I run the section that creates the message and then copy the RECEIVE section to a new query window and execute it, nothing is returned. If I run the RECEIVE section within the same query window it returns the 'Hello World' message as expected. I am new to Service Broker and so am assuming that I am missing something obvious!!
I have set up service broker to work between two instances of SQL server with Dialog Security (implemented using certificates). The initiator queue has a activation procedure attached to process the return messages.
I'm receiving the messages from inside a SSIS package using Receive statement. Once I recive the message, I store the conversation handle, message type and message body in variables and execute the remaining ETL package based on the input.
Towards the end of the package, I send a message back to the Initiator for the same conversation to indicate sucess or failure.
Code Snippet
declare @conversation_handle UNIQUEIDENTIFIER
select @conversation_handle = <<SSIS User Variable>>;
SEND ON CONVERSATION @conversation_handle MESSAGE TYPE [/OLAP/Error] (N'<Error>My custom error</Error>');
END CONVERSATION @conversation_handle ;
The problem now is that, the initiator queue receives only the "http://schemas.microsoft.com/SQL/ServiceBroker/EndDialog" message. I would expect it to recieve "/OLAP/Error" first and then the "EndDialog" message.
Any idea on what's happening here? Any help is appreciated.
My activation sp must be able to read of various queues.
I load a variable with the queue name that activated the sp btu i cannot get the syntax working to receive or get a conversation group of a queue name that is a variable.
I have tried:
WAITFOR
(
RECEIVE message_body, conversation_handle, message_type_name, message_sequence_number, conversation_group_id FROM @callingQueue INTO @msgTable WHERE conversation_group_id = @conversationGroup
), TIMEOUT 2000;
But i get this error:
Incorrect syntax near '@callingQueue'.
Looks like you cannot use a variable.
So i tried the following:
SELECT @SQL = N' WAITFOR
(
RECEIVE message_body, conversation_handle, message_type_name, message_sequence_number, conversation_group_id FROM @callingQueue INTO @msgTable WHERE conversation_group_id = @conversationGroup
Is there a way to get more than one file with a single ftp task in SQL 2005??
I need to get 5 files from one server. They are in two different directories is that makes any difference. Right now I have a separate task for each but would like to have one task if possible.
Hi i am trying to create a batch process then commit for all messages on the queue. The problem i am having is when i run my query (As below) I only receive the first message and the corresponding end dialog for the message although i have 2000 records sitting in the queue. It is my understanding that receive without any criteria i.e top(1) or where clause should select everything of the queue. I tried receive top(100) expecting 100 records but still only got 2 back.
Hi, My msdb grown up abnormally to 35 GB. I used :
use msdb go SELECT TOP 10 OBJECT_NAME([object_id]), * FROM sys.dm_db_partition_stats WHERE index_id IN (0,1) ORDER BY in_row_reserved_page_count DESC;
And i found queue_messages_407672500 table is occupying a lot of space.
When i tried to query : select TOP 5 * FROM queue_messages_407672500 ; I got error: Msg 208, Level 16, State 1, Line 1 Invalid object name 'queue_messages_407672500'.
Also , to clear the queued messages in msdb , i tried to use : RECEIVE TOP (1) * FROM queue_messages_407672500 ; But got the same error as above.
Please suggest , how can i shrink the msdb now, as without receving the messages i am not able to shrink it.
I am getting problem in unique row in database table, but not getting unique row because I have used Distinct keyword but not getting unique row so how can we do?
I have two table one table information another table Id. But second table in two code same but I am using distinct keyword i get some row unique but second table in two row in same code but when i am fetching row same auto_id render same id create duplicate row. But I am getting only unique row.
I have a set of service broker services setup that rely on external activation to process messages. I'm using the GotDotNet ExternalActivator, and it launches console applications that do the actual retrieval from the queues. The console applications are written to run continuously to avoid the cost of starting up .NET based console apps over and over again.
I am observing very odd timing behavior. With the receive queues empty and the external activator configured to run a minimum and maximum of 5 instances, I observe in SQL Profiler that most of the receive operations finish in about the same amount of time as my WAITFOR command in my receive stored procedure. However, there is usually one receive command that consistently takes upwards of 30 seconds and often causes sql timeout exceptions to be thrown. I know that I could code around this, but I wasn't really expecting this behavior.
Does anyone have any thoughts on why it might be occurring? I would have expected to routinely see my receive operations taking 15 seconds, give or take, especially when the queue is empty. Also, I have observed this behaviour on both SQL 2k5 Express and Dev Editions, so I don't think it's a version thing.
The stored procedure I am using to do the receive is:
I have a problem using service broker, a send the message from server SSB1(initiator) and a receive this message on server SSB2(target), but I don't receive response to SSB1...
In my server SSB2 has this messages on Profiler: - This message could not be delivered because it is a duplicate. - Could not forward the message because forwarding is disabled in this SQL Server instance. - The message could not be delivered because it could not be classified. Enable broker message classification trace to see the reason for the failure.
Message from SSB1 Profiler:
- This message was dropped because it could not be dispatched on time. State: 1
I am getting SQLException when I connect one of SQL Server 2000 Integrated Security host. I would like to know how to correct this problem.
An exception occurred during the DBComms.receive method. Operation:An existing connection was forcibly closed by the remote host. Context:(1) [Thread[main,5,main], IO:adc97, Dbc:8460d]. PktNum:1. TotalReceived:173. PktSize:4,096.
I understand that SQL Service Broker will RECEIVE messages in the same order of SEND, so long as the messages are on the same conversation.
I would like to accomplish queue-level ordering instead of (or in addition to) conversation-level ordering.
There is a significant business case for this level of ordering. Consider an order processing system which is specified to fulfill orders in the sequence they are received. The reason for the ordering is as follows. Suppose the process(es) that RECEIVEs from the queue is down for several hours and the messages back up in the queue. Various customers place orders throughout this period of time. If more orders are placed than there are quantity for an item, the customers who placed their orders earliest in the day ought to be the ones that receive the merchandise and the later orders should be placed on backorder.
Limited experimentation showed that SQL Server totally disregards the order in which the messages were sent (on different conversations to the same queue).
The potential solution to use the same conversation has some drawbacks:
1. Difficult to do error handling because of the way error handling works in conversations.
2. It is not possible to RECEIVE using multiple threads. (Yes, RECEIVEing on multiple threads also would reorder the messages, but the reorderings would be localized in time so this would be tolerable by a lot of applications. In other words, orders from 1:00 AM would not be mixed with orders from 9:00 AM.)
Can anyone see a good solution to this in the current version?
If there are no good solutions, it would be great if Microsoft considers adding a feature where you can declare an ordering requirement when you CREATE QUEUE. Even support for an "approximate" ordering (messages can rearrange +/- several seconds) would be helpful, but the current way which seems to totally randomize the message order is not good for certain kinds of significant applications.
I am trying to send messages between 2 different server instances. I am getting the following errors in Profiler:
"This message could not be delivered because the user with ID 0 in database ID 14 does not have permission to send to the service. Service name: 'TestService1'."
"The target service name could not be found. Ensure that the service name is specified correctly and/or the routing information has been supplied."
The scripts for object creation and messaging is following at the first server instance:

SEND ON CONVERSATION @dh MESSAGE TYPE [DEFAULT] ('this is message1');
DECLARE @status nvarchar(1024); SELECT status = GET_TRANSMISSION_STATUS(@dh);
END CONVERSATION @dh;
on second server instance:
use master GO CREATE ENDPOINT SBroker2 STATE = STARTED AS TCP ( LISTENER_PORT = 1212 ) FOR SERVICE_BROKER ( ENCRYPTION = DISABLED ); GO
in first server, in sys.transmission_queue transmission_status is empty

I have just finished going thru a long process getting SP2 CU3 patch installed.
The first file microsoft sent was corrupted and in turn corrupted my .NET Framework, had to run repair on the Framework before installing CU3. I am now on version 9.0.3186. I have two other boxes with the same version and do not have this problem
My understanding is that all of the patches/hotfixes since SP,1 that this problem was resolved
Any help will be greatly appreciated as I am in a very heavy development stage on this box.
