注釈
CreateSyncAgentByDefault では、既定値が false
に設定されます。
同期をスケジュールする必要がある場合や、SQL Server Management Studio からサブスクリプションの同期をとる必要がある場合は、CreateSyncAgentByDefault の値を true
に指定します。 SQL Server エージェントを使用せずに常にプログラムでレプリケーション エージェントを開始する場合は、値を false
に指定します。
CreateSyncAgentByDefault の値を false
に指定した場合は、MergeSynchronizationAgent プロパティまたは TransSynchronizationAgent プロパティから取得される SynchronizationAgent オブジェクトまたは SynchronizationAgent オブジェクトに、サブスクリプションの同期をとるのに十分な情報が含まれません。 詳細については、「 方法: プル サブスクリプションを同期する (RMO プログラミング)」を参照してください。
値CreateSyncAgentByDefaultのfalse
指定と呼び出しCreateは、sp_addpullsubscription_agent (Transact-SQL) を実行せずにsp_addpullsubscription (Transact-SQL) を実行したり、sp_addmergepullsubscription_agent (Transact-SQL) を実行せずにsp_addmergepullsubscription (Transact-SQL)を実行したりするのと同じです。
