MSSQL 数据库Job在不同Server之间同步

在各种高可用方案中，我们常常面临考虑 SQL Login 或者 Job 脚本需要在不同Server之间同步。

这里提供几种方式：

1.SSIS Package 传输对象

2.Powershell 脚本部署。

3.可以设置触发器或者扩展事件，监控系统表中的改动，然后启动一个PS脚本，实时同步

这里做个简单的例子，加入我们每天同步一次job，主要思路就是监控系统表中的改动，然后获取job name,

然后通过SMO获得脚本对象，在目标服务器上执行

脚本如下：

param($souceSererIP='sourceServer',$targetServerIp='.')

Import-Module sqlps -DisableNameChecking
[system.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.Smo")|Out-Null
[system.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SqlEnum")|Out-Null
[system.Reflection.Assembly]::LoadWithPartialName("Microsoft.SqlServer.SmoEnum")|Out-Null

[string] $script =''
$server=New-Object Microsoft.SqlServer.Management.Smo.Server($souceSererIP)
$dt=[System.DateTime]::Now.AddDays(-1).ToString("yyyy-MM-dd HH")+":00:00"


foreach($job in $server.JobServer.Jobs)
{
    if($job.Name -ne "test")
    {
        continue
    }
    if($job.DateLastModified -gt $dt)
    {
        $jobName=$job.Name
        $jobName=$jobName.Replace("/","_").Replace("'","_").Replace("[","_").Replace("]","_").Replace("(","_").Replace(")","_").Replace("&","_").Replace('"',"_").Replace("\","_").Replace(":","_").Replace("{","_").Replace("}","_").Replace("<","_").Replace(">","_").Replace("*","_").Replace("#","_")        
    }
    $nl="`n"
    $script='if  exists(select * from msdb.dbo.sysjobs where name=N'''+$jobName +''' )'+ $nl +'begin '+ $nl +'Exec msdb.dbo.sp_delete_job @job_name=N'''+$jobName+''' '+$nl+'end '+$nl +'GO '
    $script=$script+$nl+$job.Script()
    #$script
    try
    {
    Invoke-Sqlcmd -ServerInstance $targetServerIp -query $script -ErrorAction Stop
    }
    catch
    {
        $ErrorMessage = $_.Exception.Message
        $FailedItem = $_.Exception.ItemName
        ##send email if have issue
        #Send-MailMessage -From [email protected] -To [email protected] -Subject "HR File Read Failed!" -SmtpServer EXCH01.AD.MyCompany.Com -Body "We failed to read file $FailedItem. The error message was $ErrorMessage"
         Break
    }
    $output ='Execute success! Jobname:"{0}" from "{1}" to "{2}"' -f    $jobName,$souceSererIP,$targetServerIp
    Write-Host $output
}

我们将文件保存成syncjob.ps1，然后cmd中调用：

powershell c:\test\syncjob.ps1 sourceServer,targetServer .
