PullSubscription.SynchronizationAgentProcessSecurity Property

Gets the security context that is used to specify the Microsoft Windows account under which the Synchronization Agent job runs to synchronize the subscription.

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

public IProcessSecurityContext SynchronizationAgentProcessSecurity { get; }
/** @property */
public IProcessSecurityContext get_SynchronizationAgentProcessSecurity ()

public function get SynchronizationAgentProcessSecurity () : IProcessSecurityContext

Property Value

An IProcessSecurityContext object that represents a Windows account.

You must specify Windows account information using the IProcessSecurityContext interface returned by the SynchronizationAgentProcessSecurity property. This is not required if the subscription is created by a member of the sysadmin fixed server role at the Subscriber.

The Synchronization Agent for a pull subscription always connects locally to the Subscriber using the Windows Authentication credentials supplied using the SynchronizationAgentProcessSecurity property. For information about the connections that agents make and the permissions that are required for those connections, see Replication Agent Security Model.

The SynchronizationAgentProcessSecurity property can only be retrieved by members of the sysadmin fixed server role at the Subscriber or by members of the db_owner fixed database role on the subscription database.

The SynchronizationAgentProcessSecurity property can only be set by members of the sysadmin fixed server role at the Subscriber or by members of the db_owner fixed database role on the subscription database.

Retrieving the SynchronizationAgentProcessSecurity property is equivalent to executing sp_helppullsubscription (Transact-SQL) or sp_helpmergepullsubscription (Transact-SQL).

Setting the SynchronizationAgentProcessSecurity property is equivalent to executing sp_addpullsubscription_agent (Transact-SQL), sp_addmergepullsubscription_agent (Transact-SQL), sp_change_subscription_properties (Transact-SQL), or sp_changemergepullsubscription (Transact-SQL).

The SynchronizationAgentProcessSecurity property is available with SQL Server 2005 only.

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