SSRS 如何使用 Powershell 获取报表缓存选项?

SSRS How to Get Report Cache Options With Powershell?

在 SSRS Web 界面中,如果报告配置为 "Always run this report against pregenerated snapshots",则单击报告并转到管理 --> 缓存后,有一个 缓存快照 部分有一个选项 "Create cache snapshots on a schedule"

我一直在摆弄 PowerShell 并尝试创建一个脚本,找到设置了此选项的所有报告,并输出计划。

我有这个脚本迭代每个报告 "Execution Type" of "Snapshot",但我相信我调用了错误的方法 (GetCacheOptions),因为它 returns 是每项错误:

Clear-Host 

$webServiceUrl = 'http://myReportServer.domain.com/reportserver/reportservice2010.asmx?WSDL'

$rs = New-WebServiceProxy -Class 'RS' -Namespace 'RS' -Uri $webServiceUrl -UseDefaultCredential

$reports = $rs.ListChildren("/Some Folder", $true) | Where-Object { $_.TypeName -eq "Report" }

$schedDef = New-Object RS.ScheduleDefinition
$expDef = New-Object RS.ExpirationDefinition

foreach ($report in $reports) {

    $execType = $rs.GetExecutionOptions($report.Path, [ref]$schedDef.Item)


    if($execType -eq "Snapshot") {
        $rs.GetCacheOptions($report.Path, [ref]$expDef.Item)
    }

}

有谁知道需要调用什么方法来获取这些信息以及如何调用这个方法(即需要提供什么参数)?

编辑:

根据接受的答案的指导,我能够进行一些编辑(如下),但我没有得到我想要的时间表信息:

.......
....
foreach ($report in $reports) {

    $execResult = $rs.GetExecutionOptions($report.Path,
        [ref]$ScheduleDefinitionOrReference)

    if ($execResult -eq "Snapshot") {
        if($ScheduleDefinitionOrReference.Item -is [RS.DailyRecurrence]) {
            Write-Host "$($report.Name):" -f Green
            Write-Host "`tSchedule Information:" -f Yellow
            Write-Host "`t`tEvery $($ScheduleDefinitionOrReference.Item.Daysinterval) Day(s)"
            Write-Host "`t`tStart Time: $($ScheduleDefinitionOrReference.StartDateTime)`n"
        }

    }

您可以使用 ReportingService2010.GetItemHistoryOptions 并将 ItemPathout bool KeepExecutionSnapshotsout ScheduleDefinitionOrReference 传递给方法。

如果勾选按计划创建缓存快照

ScheduleDefinitionOrReference 将包含 ScheduleDefinition,否则其值为 NoSchedule

例子

$svcUrl = 'http://the-host-name/ReportServer/reportservice2010.asmx'
$svc = New-WebServiceProxy -Class 'RS' -Namespace 'RS' -Uri $svcUrl -UseDefaultCredential
$reports = $svc.ListChildren("/", $true) | Where-Object { $_.TypeName -eq "Report" }

$KeepExecutionSnapshots = $false
$ScheduleDefinitionOrReference = New-Object RS.ScheduleDefinitionOrReference

foreach ($report in $reports) {
    $svc.GetItemHistoryOptions($report.Path, 
        [ref]$KeepExecutionSnapshots, 
        [ref]$ScheduleDefinitionOrReference)
    $report.Path
    $ScheduleDefinitionOrReference
}
