ReplicationObject.CachePropertyChanges Property

Definition

Gets or sets whether to cache changes made to the replication properties or to apply them immediately.

public bool CachePropertyChanges { get; set; }

Property Value

A Boolean value. If true, the property changes are cached. If false, the property changes are applied immediately.

Examples

// Define the server, database, and publication names
string publisherName = publisherInstance;
string publicationName = "AdvWorksProductTran";
string publicationDbName = "AdventureWorks2012";

TransPublication publication;

// Create a connection to the Publisher.
ServerConnection conn = new ServerConnection(publisherName);

try
{
    // Connect to the Publisher.
    conn.Connect();

    // Set the required properties for the publication.
    publication = new TransPublication();
    publication.ConnectionContext = conn;
    publication.Name = publicationName;
    publication.DatabaseName = publicationDbName;

    // Explicitly enable caching of property changes on this object.
    publication.CachePropertyChanges = true;

    // If we can't get the properties for this publication, 
    // throw an application exception.
    if (publication.LoadProperties())
    {
        // Enable support for push subscriptions and disable support 
        // for pull subscriptions.
        if ((publication.Attributes & PublicationAttributes.AllowPull) != 0)
        {
            publication.Attributes ^= PublicationAttributes.AllowPull;
        }
        if ((publication.Attributes & PublicationAttributes.AllowPush) == 0)
        {
            publication.Attributes |= PublicationAttributes.AllowPush;
        }

        // Send changes to the server.
        publication.CommitPropertyChanges();
    }
    else
    {
        throw new ApplicationException(String.Format(
            "Settings could not be retrieved for the publication. " +
            "Ensure that the publication {0} exists on {1}.",
            publicationName, publisherName));
    }
}
catch (Exception ex)
{
    // Do error handling here.
    throw new ApplicationException(
        "The publication property could not be changed.", ex);
}
finally
{
    conn.Disconnect();
}

Remarks

When the value of CachePropertyChanges is false, property changes are immediately set according to the SqlExecutionModes property of the ServerConnection object. When the value is set to true, property changes will be cached until CommitPropertyChanges is called. When CommitPropertyChanges is called, all property changes after CachePropertyChanges are set according to the SqlExecutionModes property.

Caching only applies to properties stored in Microsoft SQL Server.

The default value of CachePropertyChanges is false.
