屬性值

An IProcessSecurityContext object that represents a Windows account.

備註

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 Publisher.

The synchronization agent for a push subscription always connects locally to the Distributor 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 複寫代理程式安全性模型.

When configuring a Publisher with a remote Distributor, the values supplied for all parameters, including SynchronizationAgentProcessSecurity, are sent to the Distributor as plain text. You should encrypt the connection between the Publisher and its remote Distributor before calling the Create method. For more information, see 加密 SQL Server 的連接.

The SynchronizationAgentProcessSecurity property can only be retrieved by members of the sysadmin fixed server role at the Publisher, by members of the db_owner fixed database role on the publication database, or by the user that created the subscription.

The SynchronizationAgentProcessSecurity property can only be set 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.

Retrieving the SynchronizationAgentProcessSecurity property is equivalent to executing sp_helpsubscription or sp_helpmergesubscription.

Setting properties on the returned IProcessSecurityContext interface is equivalent to executing sp_addsubscriptionsp_addmergesubscription, sp_changesubscription, or sp_changemergesubscription.

The SynchronizationAgentProcessSecurity property is available with Microsoft SQL Server 2005 only.

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