有沒有辦法在不使用令牌的情況下監視事務複製延遲？

Question

當我在複製的出版物上有延遲時，我會添加一個令牌並觀察它。 有沒有任何方法可以在不使用標記的情況下解決複製延遲問題？ 這是SQL Server 2005-事務複製。

我發現這個鏈接約checking replication latency using T-SQL 並創建了我的環境中的過程，它的工作非常好。

這裏是過程的代碼，在評論中，我是如何利用它的。

USE [MY_PUBLICATION_DATABASE] 
-- this procedure is to be created inside the publication database 
GO 
Create Procedure dbo.dba_replicationLatencyGet_sp 

     /* Declare Parameters */ 
      @publicationToTest sysname  = N'yourPublicationName' 
     , @replicationDelay varchar(10) = N'00:00:30' 
     , @iterations  int   = 5 
     , @iterationDelay varchar(10) = N'00:00:30' 
     , @deleteTokens  bit   = 1 
     , @deleteTempTable bit   = 1 
As 
/********************************************************************************* 
    Name:  dba_replicationLatencyGet_sp 

    Author:  Michelle F. Ufford 

    Purpose: Retrieves the amount of replication latency in seconds 

    Notes:  Default settings will run 1 test every minute for 5 minutes. 

       @publicationToTest = change the default to your publication 

       @replicationDelay = how long to wait for the token to replicate; 
        probably should not set to anything less than 10 (in seconds) 

       @iterations = how many tokens you want to test 

       @iterationDelay = how long to wait between sending test tokens 
        (in seconds) 

       @deleteTokens = whether you want to retain tokens when done 

       @deleteTempTable = whether or not to retain the temporary table 
        when done. Data stored to ##tokenResults; set @deleteTempTable 
        flag to 0 if you do not want to delete when done.

    I found this wonderful procedure at this site: 
    http://sqlfool.com/2008/11/checking-replication-latency-with-t-sql/ 

    I have tested it 
    Server: SQLWEBLON1.DEV.BODEN.LOCAL 
    DB: AUAccount 

    I had to create the procedure in the Publisher database, and run it from there. 

     Exec dbo.dba_replicationLatencyGet_sp 
      @publicationToTest = N'AUAccount' 
     , @replicationDelay  = N'00:00:05' 
     , @iterations   = 1 
     , @iterationDelay  = N'00:00:05' 
     , @deleteTokens   = 1 
     , @deleteTempTable  = 1;

您可以通過使用和複製日期時間列並使用發佈服務器上每X分鐘的當前時間戳更新它來推出自己的解決方案。然後，在訂閱服務器上，您可以每X分鐘運行一次作業，並將日期時間列值與當前時間進行比較，並在差異大於X分鐘時發出警報。
