USE TankTracker

ALTER DATABASE TankTracker SET ENABLE_BROKER;

CREATE MASTER KEY

GO

-- create a queue

create QUEUE LogSQLQueue with activation(procedure_name =
dbo.usp_ProcessSQLEventNotifications,

max_queue_readers = 3, execute as self)

GO

-- the event notifications contract

create SERVICE LogSQLService

ON QUEUE LogSQLQueue

(
