注釈
IProcessSecurityContext プロパティによって返される SynchronizationAgentProcessSecurity インターフェイスを使用して、Windows アカウント情報を指定する必要があります。 サブスクリプションが sysadmin 固定サーバー ロールのメンバーによってサブスクライバーで作成されている場合、これは必要ありません。
プル サブスクリプション用の同期エージェントからサブスクライバーへの接続は、常にローカルであり、SynchronizationAgentProcessSecurity プロパティを使用して指定される Windows 認証の資格情報が使用されます。 エージェントが作成する接続と、それらの接続に必要なアクセス許可については、「 レプリケーション エージェント セキュリティ モデル」を参照してください。
SynchronizationAgentProcessSecurity プロパティを取得できるのは、サブスクライバー側の固定サーバー ロール sysadmin のメンバー、またはサブスクリプション データベースの固定データベース ロール db_owner のメンバーだけです。
SynchronizationAgentProcessSecurity プロパティを設定できるのは、サブスクライバー側の固定サーバー ロール sysadmin のメンバー、またはサブスクリプション データベースの固定データベース ロール db_owner のメンバーだけです。
プロパティの SynchronizationAgentProcessSecurity 取得は、 sp_helppullsubscription (Transact-SQL) または sp_helpmergepullsubscription (Transact-SQL) の実行と同じです。
プロパティの SynchronizationAgentProcessSecurity 設定は、 sp_addpullsubscription_agent (Transact-SQL)、 sp_addmergepullsubscription_agent (Transact-SQL)、 sp_change_subscription_properties (Transact-SQL)、または sp_changemergepullsubscription (Transact-SQL) の実行と同じです。
