我有一个表,使用服务代理实现的表上的触发器。每天有超过五十万条记录插入到表格中。
异步SP用于通过使用插入的数据检查几个条件并更新其他表。它在过去的1个月里运行良好,SP在执行记录的2-3秒内被执行。但现在需要90多分钟。
目前sys.conversation_endpoints记录太多。
(请注意,所有表每天都会被截断,因为我不需要那些记录)
其他数据库活动正常(平均60%的CPU利用率)。
现在我需要看看?
我可以毫无问题地重新创建数据库,但我不认为这是解决问题的好方法

你可以'结束对话@handle'或'结束对话@handle with cleanup'
答案 1 :(得分:0)
用于结束特定服务的所有对话的脚本:
DECLARE @sql NVARCHAR(MAX)
,@far_service NVARCHAR(256) = N'far_service_name';
WHILE EXISTS (
SELECT COUNT(*)
FROM sys.conversation_endpoints
WHERE far_service = @far_service
)
BEGIN
SET @sql = N'';
SELECT TOP 1000 @sql = @sql + N'END CONVERSATION ''' + CAST(conversation_handle AS NVARCHAR(50)) + N''' WITH CLEANUP;
'
FROM sys.conversation_endpoints
WHERE far_service = @far_service;
--PRINT @sql;
EXEC sys.sp_executesql @stmt = @sql;
--RETURN;
END;
GO

在修改@thesqldev中的代码后,这是我的解决方案
USE [MY_DATABASE_NAME_HERE]
GO
SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO
CREATE PROCEDURE [dbo].[mqConversationsClearAll]
AS
-- Note: you can check the queue by running this query
-- SELECT * FROM sys.conversation_endpoints GO
DECLARE @getid CURSOR
,@sql NVARCHAR(MAX)
,@conv_id NVARCHAR(100)
,@conv_handle NVARCHAR(100)
,@conv_service NVARCHAR(100)
-- ,@far_service NVARCHAR(256) = N'One_Specific_Service_Target';
-- want to create and execute a chain of statements like this, one per conversation
-- END CONVERSATION 'FE851F37-218C-EA11-B698-4CCC6AD00AE9' WITH CLEANUP;
-- END CONVERSATION 'A4B4F603-208C-EA11-B698-4CCC6AD00AE9' WITH CLEANUP;
SET @getid = CURSOR FOR
SELECT [conversation_id], [conversation_handle], [far_service]
FROM sys.conversation_endpoints
WHERE NOT([State] = 'CO')
-- CO = CONVERSING [State]
-- alternatively, might like one service name only
-- WHERE far_service = @far_service
OPEN @getid
FETCH NEXT
FROM @getid INTO @conv_id, @conv_handle, @conv_service
WHILE @@FETCH_STATUS = 0
BEGIN
SET @sql = 'END CONVERSATION ' + char(39) + @conv_handle + char(39) + ' WITH CLEANUP;'
EXEC sys.sp_executesql @stmt = @sql;
FETCH NEXT
FROM @getid INTO @conv_id, @conv_handle, @conv_service
END
CLOSE @getid
DEALLOCATE @getid
然后,每当您要清除sys.conversation_endpoints时,都可以执行新创建的存储过程“ mqConversationsClearAll”
