Question

下午好，

我创建了一个包含单个包的SSIS项目。当我从服务器手动执行时，SSIS项目和包正如我所期望的那样工作。我想如果我在服务器上设置环境变量并将其映射到项目。除非另有说明，否则每次执行包时项目都会使用这些变量。以下代码是我的VB代码

'VB.Net code
Imports System.Data.SqlClient
Imports Microsoft.SqlServer.Management.IntegrationServices
Imports System.Collections.ObjectModel

Public Class Form1

    Private Sub StartPackageButton_Click(sender As System.Object, e As System.EventArgs) Handles StartPackageButton.Click
        Try
        ' Connection to the database server where the packages are located
        Dim ssisConnection As New SqlConnection("Data Source=" + txtServerName.Text + ";Integrated Security=SSPI;")

        ' SSIS server object with connection
        Dim ssisServer As New IntegrationServices(ssisConnection)


        ' The reference to the package which you want to execute
        Dim ssisPackage As PackageInfo = ssisServer.Catalogs("SSISDB").Folders("SSIS_PROJECTS").Projects("AgressoExport").Packages("File56Export.dtsx")

        ' Add a parameter collection for 'system' parameters (ObjectType = 50), package parameters (ObjectType = 30) and project parameters (ObjectType = 20)
        Dim executionParameters As New Collection(Of PackageInfo.ExecutionValueParameterSet)

        ' Add execution parameter to override the default asynchronized execution. If you leave this out the package is executed asynchronized
        Dim executionParameter1 As New PackageInfo.ExecutionValueParameterSet
        executionParameter1.ObjectType = 50
        executionParameter1.ParameterName = "SYNCHRONIZED"
        executionParameter1.ParameterValue = 1
        executionParameters.Add(executionParameter1)

        ' Add execution parameter (value) to override the default logging level (0=None, 1=Basic, 2=Performance, 3=Verbose)
        Dim executionParameter2 As New PackageInfo.ExecutionValueParameterSet
        executionParameter2.ObjectType = 50
        executionParameter2.ParameterName = "LOGGING_LEVEL"
        executionParameter2.ParameterValue = 3
        executionParameters.Add(executionParameter2)

        ' Add execution parameter (value) to override the default logging level (0=None, 1=Basic, 2=Performance, 3=Verbose)
        Dim executionParameter3 As New PackageInfo.ExecutionValueParameterSet
        If (Trim(txtPreviousID.Text) <> "") Then
            executionParameter3.ObjectType = 20
            executionParameter3.ParameterName = "PreviousBatchID"
            executionParameter3.ParameterValue = txtPreviousID.Text
            executionParameters.Add(executionParameter3)
        End If

        ' Get the identifier of the execution to get the log
        Dim executionIdentifier As Long = ssisPackage.Execute(False, Nothing, executionParameters)

        ' Loop through the log and add the messages to the listbox
        For Each message As OperationMessage In ssisServer.Catalogs("SSISDB").Executions(executionIdentifier).Messages
            SSISMessagesListBox.Items.Add(message.MessageType.ToString() + ": " + message.Message)
        Next
    Catch ex As Exception
        If ex.InnerException IsNot Nothing Then
            SSISMessagesListBox.Items.Add(ex.Message.ToString() + " : " + ex.InnerException.Message.ToString())
        Else
            SSISMessagesListBox.Items.Add(ex.Message.ToString())
        End If
    End Try
    End Sub
End Class

我开始认为在SSIS方面我没有正确理解环境。我的环境在各自的服务器上设置为TEST和PROD，相同的变量名称映射到相同的参数但具有不同的值。我开始相信我应该在TEST和PROD服务器上都有相同的环境名称，我也会使用我的VB代码来引用它。尽管如此，我还是无法找到如何使用VB引用环境。

我很感激有关此事的任何帮助。

干杯，乔纳森

Answer 1

出于此目的，ssis已经提供了配置功能，您只需为不同的环境创建单独的cofig文件或数据库条目。

Answer 2

您需要将程序包的1. net-ssh-4.0.0.alpha4属性设置为环境的ID。

要获取环境ID，请尝试：

reference

Answer 3

能够在Visual Basic .NET程序中使用环境。您需要声明Environment Reference并将引用传递给SSIS包的Execute方法。

以下代码块是如何完成的：

Dim re As EnvironmentReference
re = ssisServer.Catalogs("SSISDB").Folders("SSIS_PROJECTS").Projects("AgressoExport").References("AgressoExport", ".")

Dim executionIdentifier As Long = ssisPackage.Execute(False, re, executionParameters)

SSISDB是目录名称，SSIS_PROJECTS是我正在使用的目录下的文件夹名称。 AgressoExport是我的项目名称。（“AgressoExport”，“。”）是指环境文件夹根目录下我的项目名为AgressoExport的环境。
