我刚刚使用 SQL Server Profiler 监视了我的 SQL Server 数据库请求。我认为ReportServer数据库每 5 秒发送 2 个批处理请求 - 见下图。

我还在我的本地数据库引擎上进行了尝试，以确保没有从用户那里调用任何报告，但是请求再次每 5 秒发送一次，与服务器相同

在此处输入图像描述

我阅读了两个请求的内容，这对于所有请求都是相同的，其中一个更新数据库event表，ReportServer然后从event表中选择前 8 个

另一个更新 notification表，然后从notification与其他三个表连接的表中选择前 8 个

这是 Profiler 的 textData 列中的代码（批量查询）

请求 1：

declare @BatchID uniqueidentifier
set @BatchID = NEWID()

UPDATE [Event] WITH (TABLOCKX)
SET [BatchID] = @BatchID,
    [ProcessStart] = GETUTCDATE(),
    [ProcessHeartbeat] = GETUTCDATE()
FROM 
    (SELECT TOP 8 [EventID] 
     FROM [Event] WITH (TABLOCKX) 
     WHERE [ProcessStart] IS NULL 
     ORDER BY [TimeEntered]) AS t1
WHERE 
    [Event].[EventID] = t1.[EventID]

SELECT TOP 8
    E.[EventID], E.[EventType], E.[EventData]
FROM
    [Event] E WITH (TABLOCKX)
WHERE
    [BatchID] = @BatchID
ORDER BY 
    [TimeEntered]

要求 2：

declare @BatchID uniqueidentifier
set @BatchID = newid()

UPDATE [Notifications] WITH (TABLOCKX)
SET [BatchID] = @BatchID,
    [ProcessStart] = GETUTCDATE(),
    [ProcessHeartbeat] = GETUTCDATE()
FROM 
    (SELECT TOP 8 [NotificationID] 
     FROM [Notifications] WITH (TABLOCKX) 
     WHERE ProcessStart IS NULL 
       AND (ProcessAfter IS NULL OR ProcessAfter < GETUTCDATE()) 
     ORDER BY [NotificationEntered]) AS t1
WHERE 
    [Notifications].[NotificationID] = t1.[NotificationID]

SELECT TOP 8
    -- Notification data
    N.[NotificationID], N.[SubscriptionID], N.[ActivationID],
    N.[ReportID], N.[SnapShotDate], N.[DeliveryExtension],
    N.[ExtensionSettings], N.[Locale], N.[Parameters],
    N.[SubscriptionLastRunTime], N.[ProcessStart],
    N.[NotificationEntered], N.[Attempt], N.[IsDataDriven],
    SUSER_SNAME(Owner.[Sid]),
    Owner.[UserName],
    -- Report Data
    O.[Path], N.[ReportZone], O.[Type], SD.NtSecDescPrimary,
    N.[Version], Owner.[AuthType], SR.[SubscriptionResult]
FROM
    [Notifications] N WITH (TABLOCKX) 
INNER JOIN
    [Catalog] O ON O.[ItemID] = N.[ReportID]
INNER JOIN
    [Users] Owner ON N.SubscriptionOwnerID = Owner.UserID
LEFT OUTER JOIN 
    [SecData] SD ON O.[PolicyID] = SD.[PolicyID] AND SD.AuthType = Owner.AuthType
LEFT OUTER JOIN 
   [SubscriptionResults] SR ON N.[SubscriptionID] = SR.[SubscriptionID] 
                            AND CHECKSUM(convert(nvarchar(max), N.[ExtensionSettings])) = SR.[ExtensionSettingsHash]
WHERE
    N.[BatchID] = @BatchID
ORDER BY 
    [NotificationEntered]

首先，我想知道这些烦人的请求每 5 秒发送一次的原因是什么，即使所有请求中的两个选择的结果都是空的，并且没有对报告服务的实际请求（似乎他们没有做任何特别的事情，因为事件和通知表都是空的）

其次，我怎样才能停止这个从数据库每 5 秒发送一次无用请求**的过程ReportServer？

请注意，我想让我的报告服务保持正常运行，这样我就无法停止它的服务，我只想停止发送无用的请求。

提前致谢
