Invokes inline publication validation for all subscriptions.

Namespace: Microsoft.SqlServer.Replication
Assembly: Microsoft.SqlServer.Rmo (in microsoft.sqlserver.rmo.dll)

Syntax

'Declaration
Public Sub ValidatePublication ( _
    validationOption As ValidationOption, _
    validationMethod As ValidationMethod, _
    shutdownAgent As Boolean _
)

public void ValidatePublication (
    ValidationOption validationOption,
    ValidationMethod validationMethod,
    bool shutdownAgent
)

public:
void ValidatePublication (
    ValidationOption validationOption, 
    ValidationMethod validationMethod, 
    bool shutdownAgent
)

public void ValidatePublication (
    ValidationOption validationOption, 
    ValidationMethod validationMethod, 
    boolean shutdownAgent
)

public function ValidatePublication (
    validationOption : ValidationOption, 
    validationMethod : ValidationMethod, 
    shutdownAgent : boolean
)

Parameters

validationOption
A ValidationOption object value that specifies the type of validation being performed.

validationMethod
A ValidationMethod object value that specifies options for rowcount validation.

shutdownAgent
A Boolean value. If true, the Distribution Agent is shut down immediately after validation. If false, the Distribution Agent continues to run.

Remarks

The result of the validation is written to the agent history, which is viewed using Replication Monitor. For more information, see Monitoring Replication with Replication Monitor.

The ValidatePublication method can only be called by members of the sysadmin fixed server role at the Publisher or by members of the db_owner fixed database role on the publication database.

Calling ValidatePublication is equivalent to executing sp_publication_validation.

The ValidatePublication method is available for instances of SQL Server 2000 and SQL Server 2005.

This namespace, class, or member is supported only in version 2.0 of the .NET Framework.

Example

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

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;

    // If we can't get the properties for this publication, 
    // throw an application exception.
    if (publication.LoadProperties())
    {
        // Initiate validataion for all subscriptions to this publication.
        publication.ValidatePublication(ValidationOption.RowCountOnly,
            ValidationMethod.ConditionalFast, false);

        // If not already running, start the Distribution Agent at each 
        // Subscriber to synchronize and validate the subscriptions.
    }
    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(
        "Subscription validation could not be initiated.", ex);
}
finally
{
    conn.Disconnect();
}
