説明
SnapshotGenerationAgent クラスを使用すると、プログラムで直接スナップショット エージェントにアクセスできます。
SnapshotGenerationAgent クラスでは、次のレプリケーション タスクを実行するための機能がサポートされています。
初期スナップショットを生成する。
パラメータ化されたフィルタに基づいて定義されるサブスクリプションのパーティション スナップショットを生成する。
使用例
この例では、トランザクション パブリケーションの標準のスナップショットを生成します。
// Set the Publisher, publication database, and publication names.
string publicationName = "AdvWorksProductTran";
string publicationDbName = "AdventureWorks";
string publisherName = publisherInstance;
string distributorName = publisherInstance;
SnapshotGenerationAgent agent;
try
{
// Set the required properties for Snapshot Agent.
agent = new SnapshotGenerationAgent();
agent.Distributor = distributorName;
agent.DistributorSecurityMode = SecurityMode.Integrated;
agent.Publisher = publisherName;
agent.PublisherSecurityMode = SecurityMode.Integrated;
agent.Publication = publicationName;
agent.PublisherDatabase = publicationDbName;
agent.ReplicationType = ReplicationType.Transactional;
// Start the agent synchronously.
agent.GenerateSnapshot();
}
catch (Exception ex)
{
// Implement custom application error handling here.
throw new ApplicationException(String.Format(
"A snapshot could not be generated for the {0} publication."
, publicationName), ex);
}
' Set the Publisher, publication database, and publication names.
Dim publicationName As String = "AdvWorksProductTran"
Dim publicationDbName As String = "AdventureWorks"
Dim publisherName As String = publisherInstance
Dim distributorName As String = publisherInstance
Dim agent As SnapshotGenerationAgent
Try
' Set the required properties for Snapshot Agent.
agent = New SnapshotGenerationAgent()
agent.Distributor = distributorName
agent.DistributorSecurityMode = SecurityMode.Integrated
agent.Publisher = publisherName
agent.PublisherSecurityMode = SecurityMode.Integrated
agent.Publication = publicationName
agent.PublisherDatabase = publicationDbName
agent.ReplicationType = ReplicationType.Transactional
' Start the agent synchronously.
agent.GenerateSnapshot()
Catch ex As Exception
' Implement custom application error handling here.
Throw New ApplicationException(String.Format( _
"A snapshot could not be generated for the {0} publication." _
, publicationName), ex)
End Try
この例では、マージ パブリケーションの標準のスナップショットを生成します。
// Set the Publisher, publication database, and publication names.
string publicationName = "AdvWorksSalesOrdersMerge";
string publicationDbName = "AdventureWorks";
string publisherName = publisherInstance;
string distributorName = publisherInstance;
SnapshotGenerationAgent agent;
try
{
// Set the required properties for Snapshot Agent.
agent = new SnapshotGenerationAgent();
agent.Distributor = distributorName;
agent.DistributorSecurityMode = SecurityMode.Integrated;
agent.Publisher = publisherName;
agent.PublisherSecurityMode = SecurityMode.Integrated;
agent.Publication = publicationName;
agent.PublisherDatabase = publicationDbName;
agent.ReplicationType = ReplicationType.Merge;
// Start the agent synchronously.
agent.GenerateSnapshot();
}
catch (Exception ex)
{
// Implement custom application error handling here.
throw new ApplicationException(String.Format(
"A snapshot could not be generated for the {0} publication."
, publicationName), ex);
}
' Set the Publisher, publication database, and publication names.
Dim publicationName As String = "AdvWorksSalesOrdersMerge"
Dim publicationDbName As String = "AdventureWorks"
Dim publisherName As String = publisherInstance
Dim distributorName As String = publisherInstance
Dim agent As SnapshotGenerationAgent
Try
' Set the required properties for Snapshot Agent.

agent.Publisher = publisherName
agent.PublisherSecurityMode = SecurityMode.Integrated
agent.Publication = publicationName

agent.ReplicationType = ReplicationType.Merge
' Start the agent synchronously.
agent.GenerateSnapshot()
Catch ex As Exception
' Implement custom application error handling here.
Throw New ApplicationException(String.Format( _
"A snapshot could not be generated for the {0} publication." _
, publicationName), ex)
End Try
この例では、HOST_NAME 関数をオーバーロードして、フィルタが適用されたデータ スナップショットを生成します。このスナップショットはパラメータ化されたフィルタを持つマージ パブリケーションのサブスクリプションに対するものです。
// Set the Publisher, publication database, and publication names.
string publicationName = "AdvWorksSalesOrdersMerge";
string publicationDbName = "AdventureWorks";
string publisherName = publisherInstance;
string distributorName = publisherInstance;

{
// Set the required properties for Snapshot Agent.
agent = new SnapshotGenerationAgent();
agent.Distributor = distributorName;
agent.DistributorSecurityMode = SecurityMode.Integrated;
agent.Publisher = publisherName;
agent.PublisherSecurityMode = SecurityMode.Integrated;
agent.Publication = publicationName;
agent.PublisherDatabase = publicationDbName;
agent.ReplicationType = ReplicationType.Merge;
// Specify the partition information to generate a
// filtered snapshot based on Hostname.
agent.DynamicFilterHostName = hostname;
// Start the agent synchronously.
agent.GenerateSnapshot();
}
catch (Exception ex)
{
// Implement custom application error handling here.
throw new ApplicationException(String.Format(
"A snapshot could not be generated for the {0} publication."
, publicationName), ex);
}
