Замечания

The SnapshotGenerationAgent class provides direct, programmatic access to the Snapshot Agent.

The SnapshotGenerationAgent class supports the ability to do the following replication tasks:

• Generate the initial snapshot

• Generate a partitioned snapshot for a subscription defined based-on a parameterized filter.

Примеры

This example generates a standard snapshot for a transactional publication.

           // Set the Publisher, publication database, and publication names.
            string publicationName = "AdvWorksProductTran";
            string publicationDbName = "AdventureWorks2012";
            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 = "AdventureWorks2012"
Dim publisherName As String = publisherInstance
Dim distributorName As String = publisherInstance

Dim agent As SnapshotGenerationAgent

    ' 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

This example generates a standard snapshot for a merge publication.

// Set the Publisher, publication database, and publication names.
string publicationName = "AdvWorksSalesOrdersMerge";
string publicationDbName = "AdventureWorks2012";
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 = "AdventureWorks2012"
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.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

This example overloads the HOST_NAME function to generate a filtered data snapshot for a subscription to a merge publication that has a parameterized filter.

           // Set the Publisher, publication database, and publication names.
            string publicationName = "AdvWorksSalesOrdersMerge";
            string publicationDbName = "AdventureWorks2012";
            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;

                // 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);
            }
