TransPublication.ValidatePublication Method

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 _
)
'Usage
Dim instance As TransPublication
Dim validationOption As ValidationOption
Dim validationMethod As ValidationMethod
Dim shutdownAgent As Boolean

instance.ValidatePublication(validationOption, _
    validationMethod, shutdownAgent)

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

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

member ValidatePublication : 
        validationOption:ValidationOption * 
        validationMethod:ValidationMethod * 
        shutdownAgent:bool -> unit 

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

Parameters

  • shutdownAgent
    Type: System.Boolean
    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.

Examples

            // 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;
