Broker:Conversation Event Class
SQL Server generates a Broker:Conversation event to report the progress of a Service Broker conversation.
The name of the client application that created the connection to an instance of SQL Server. This column is populated with the values passed by the application instead of the displayed name of the program.
The ID assigned by the host computer to the process where the client application is running. This data column is populated if the client process ID is provided by the client.
The ID of the database that is specified by the USE database statement. If no USE databasestatement has been issued, the ID of the default database. SQL Server Profiler displays the name of the database if the Server Name data column is captured in the trace and the server is available. Determine the value for a database by using the DB_ID function.
The type of event class captured. Always 124 for Broker:Conversation.
Sequence number for this event.
The type of event subclass. This provides more information about each event class.
The conversation ID of the dialog. This identifier is transmitted as part of the message, and is shared between both sides of the conversation.
The name of the computer on which the client is running. This data column is populated if the host name is provided by the client. To determine the host name, use the HOST_NAME function.
Indicates whether the event occurred on a system process or a user process.
0 = user
1 = system
The security identification number (SID) of the logged-in user. Each SID is unique for each login in the server.
The conversation group that the conversation belongs to.
The Windows domain to which the user belongs.
The name of the user that owns the connection that generated this event.
The conversation handle of the dialog.
The priority level of the conversation
The role of the conversation handle. This is either initiator or target.
The name of the instance of SQL Server that is being traced.
The SQL Server error severity, if this event reports an error.
The server process ID that is assigned by SQL Server to the process that is associated with the client.
The time when the event started, when available.
The current state of the conversation. One of the following:
The system-assigned ID of the transaction.
The following table lists the subclass values for this event class.
SQL Server generates a SEND Message event when the Database Engine executes a SEND statement.
SQL Server generates an END CONVERSATION event when the Database Engine executes an END CONVERSATION statement that does not include the WITH ERROR clause.
END CONVERSATION WITH ERROR
SQL Server generates an END CONVERSATION WITH ERROR event when the Database Engine executes an END CONVERSATION statement that includes the WITH ERROR clause.
Broker Initiated Error
SQL Server generates a Broker Initiated Error event whenever Service Broker creates an error message. For example, when Service Broker cannot successfully route a message for a dialog, the broker creates an error message for the dialog and generates this event. SQL Server does not generate this event when an application program ends a conversation with an error.
Service Broker terminated the dialog. Service Broker terminates dialogs in response to conditions that prevent the dialog from continuing, but which are not errors or the normal end of a conversation. For example, dropping a service causes Service Broker to terminate all dialogs for that service.
Received Sequenced Message
SQL Server generates a Received Sequenced Message event class when SQL Server receives a message that contains a message sequence number. All user-defined message types are sequenced messages. Service Broker generates an unsequenced message in two cases:
Received END CONVERSATION
SQL Server generates a Received END CONVERSATION event when SQL Server receives an End Dialog message from the other side of the conversation.
Received END CONVERSATION WITH ERROR
SQL Server generates a Received END CONVERSATION WITH ERROR event when SQL Server receives a user-defined error from the other side of the conversation. SQL Server does not generate this event when SQL Server receives a broker-defined error.
Received Broker Error Message
SQL Server generates a Received Broker Error Message event when Service Broker receives a broker-defined error message from the other side of the conversation. SQL Server does not generate this event when Service Broker receives an error message that was generated by an application.
For example, if the current database contains a default route to a forwarding database, Service Broker routes a message with an unknown service name to the forwarding database. If that database cannot route the message, the broker in that database creates an error message and returns that error message to the current database. When the current database receives the broker-generated error from the forwarding database, the current database generates a Received Broker Error Message event.
Received END CONVERSATION Ack
SQL Server generates a Received END CONVERSATION Ack event class when the other side of a conversation acknowledges an End Dialog or Error message sent by this side of the conversation.
SQL Server generates a BEGIN DIALOG event when the Database Engine executes a BEGIN DIALOG command.
SQL Server generates a Dialog Created event when Service Broker creates an endpoint for a dialog. Service Broker creates an endpoint whenever a new dialog is established, regardless of whether the current database is the initiator or the target of the dialog.
END CONVERSATION WITH CLEANUP
SQL Server generates an END CONVERSATION WITH CLEANUP event when the Database Engine executes an END CONVERSATION statement that includes the WITH CLEANUP clause.
