Notes

The HistoryRetention property can only be retrieved by members of the db_owner or replmonitor fixed database role on the distribution database, by users in the publication access list (PAL) of a publication using the distribution database, or by users with SELECT permission on the MSdistributiondbs system table in the distribution database.

The HistoryRetention property can only be set by members of the sysadmin fixed server role at the Distributor.

Retrieving the HistoryRetention property is equivalent to executing sp_helpdistributiondb.

Setting the HistoryRetention property is equivalent to executing sp_adddistributiondb or sp_changedistributiondb.

The HistoryRetention property is available with SQL Server 7.0, SQL Server 2000, and SQL Server 2005.

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

// Set the server and database names

ReplicationDatabase publicationDb;

// Create a connection to the server using Windows Authentication.
ServerConnection conn = new ServerConnection(publisherName);

try

    // Connect to the server acting as the Distributor 
    // and local Publisher.

    // Define the distribution database at the Distributor,
    // but do not create it now.
    distributionDb = new DistributionDatabase(distributionDbName, conn);
