注释
An instance of SQL Server acting as the master server for multiserver administration initiates tasks that create, modify, and delete jobs and job steps for target servers. Other tasks start or stop running jobs, coordinate polling, and so on. A target server polls its master server, retrieving and performing the tasks posted.
Due to polling, there is a lag between master server task assignment and its implementation by the target server. For example, a master server could delete a job step within a multiserver job. When the target server polls, it retrieves the task, an instruction to delete the job step, and the master server is altered, indicating that the pending instruction has been retrieved.
