如何检查复制快照代理状态?

我想在使用此声明启动代理后检查代理的状态

EXEC sp_startpublication_snapshot @publication

因为我想做下一步需要已经开始的工作。

我不相信有一个内置的复制存储过程来检查快照代理状态,我可能是错的。但是,您可以查询MSsnapshot_history。这样的事情可以解决问题:

SELECT 
    agent_id, 
    runstatus, 
    start_time, 
    time, 
    duration, 
    comments, 
    delivered_transactions,
    delivered_commands, 
    delivery_rate, 
    error_id, 
    timestamp 
FROM dbo.MSsnapshot_history
WHERE comments = 'Starting agent.'

同样,您可以检查快照代理何时完成:

SELECT 
    agent_id, 
    runstatus, 
    start_time, 
    time, 
    duration, 
    comments, 
    delivered_transactions,
    delivered_commands, 
    delivery_rate, 
    error_id, 
    timestamp 
FROM dbo.MSsnapshot_history
WHERE comments = '[100%] A snapshot of 68 article(s) was generated.'

或者,您可以使用sp_help_job来获取快照代理作业的状态。

经过一番研究后我得到了一个解决方法

SELECT snapshot_ready FROM sysmergepublications 

如果未准备好,则此查询返回0,如果已启动,则返回1

感谢所有人的贡献:)

您还可以使用while循环在执行其他脚本之前检查代理是否正在运行:

use [distribution];
declare @status int = 2

 select @status = status
 FROM dbo.MSReplication_monitordata
 WHERE publication = 'PublicationName' and agent_type = 1

 while @status = 3
 begin
 WAITFOR DELAY '00:00:03'
 select @status = status
 FROM dbo.MSReplication_monitordata
 WHERE publication = 'Publication.Name' and agent_type = 1
 end

我意识到这是一个较旧的线程。但是,由于这仍然很可能是当前版本的SQL(在此更新中为2017/2019)需要完成的工作,因此这是我在Powershell中使用的功能。其目的是坐在快照可用之前,然后在我们的DEV / QA环境中重建复制。

# =======================================================================================================================================
# WAIT UNTIL SNAPSHOT CREATED
# =======================================================================================================================================
Function Wait-ForSnapshotCreation {
    [Cmdletbinding()]

    Param (
        [int] $InitialSleepInSec = 60
       ,[int] $IncrementalSleepInSec = 2
       ,[string] $ReplicationPublication
       ,[string] $ReplicationDistributor
    )

    Process {
        $SleepMessage = "Sleeping for {0} seconds at the start..." -f $InitialSleepInSec
        $TotalSleepInSec = $SleepInSec
        $MonitorSQL = "exec sp_replmonitorhelppublication @publication = N'$ReplicationPublication'"
        Write-Message -Message ($SleepMessage)
        Start-Sleep -s $InitialSleepInSec

        Do {
             $MonitorStatus = (Invoke-SQLCmd -Query ($MonitorSQL) -ServerInstance $ReplicationDistributor -Database 'Distribution' -AbortOnError)
             If ($MonitorStatus.status -eq 3) {
                 $SleepMessage = "Replication status is still 'running' (3).   Will sleep for {0} more seconds. Slept {1} seconds so far..." -f $IncrementalSleepInSec, $TotalSleepInSec
                 Write-Message -Message ($SleepMessage)

                 Start-Sleep -s $IncrementalSleepInSec
                 $TotalSleepInSec += $IncrementalSleepInSec

             } # If...

        } Until ($MonitorStatus.status -ne 3)

    } # Process

} # Function

以下是一个示例调用(在创建订阅者之前使用):

Wait-ForSnapshotCreation -InitialSleepInSec 15 -IncrementalSleepInSec 1 -ReplicationPublication '<YOUR_PUBLICATION>' -ReplicationDistributor '<YOUR_DISTRIBUTION_SERVER_INSTANCE>'

检查其运行状态。以下是它的价值观:  1 =开始。

2 =成功。

3 =正在进行中。

4 =空闲。

5 =重试。

6 =失败。
