每个特定时间段运行程序的建议

Question

有一个程序可以对 SharePoint 中存储的文档进行爬网和索引。我需要每隔一段时间运行一次。我们的一些建议：

• 将应用程序转移到 Windows 服务中并安排它在每个周期运行。
• 有一个程序可以在每个时间段触发此应用程序。

您认为这两种方式哪种更有效率。任何其他建议都非常受欢迎。谢谢。

Answer 1

使用任务计划程序< Windows 的 /strong>。

Answer 2

如果您的程序足够简单，我将使用 Windows 的任务计划程序定期运行它（您的选项#2）。无需为此编写 Windows 服务。

Answer 3

您可以使用 DOS“AT”命令来安排任务运行。

The AT command schedules commands and programs to run on a computer at
a specified time and date. The Schedule service must be running to use
the AT command.

AT [\\computername] [ [id] [/DELETE] | /DELETE [/YES]]
AT [\\computername] time [/INTERACTIVE]
    [ /EVERY:date[,...] | /NEXT:date[,...]] "command"

\\computername     Specifies a remote computer. Commands are scheduled on the
                   local computer if this parameter is omitted.
id                 Is an identification number assigned to a scheduled
                   command.
/delete            Cancels a scheduled command. If id is omitted, all the
                   scheduled commands on the computer are canceled.
/yes               Used with cancel all jobs command when no further
                   confirmation is desired.
time               Specifies the time when command is to run.
/interactive       Allows the job to interact with the desktop of the user
                   who is logged on at the time the job runs.
/every:date[,...]  Runs the command on each specified day(s) of the week or
                   month. If date is omitted, the current day of the month
                   is assumed.
/next:date[,...]   Runs the specified command on the next occurrence of the
                   day (for example, next Thursday).  If date is omitted, the
                   current day of the month is assumed.
"command"          Is the Windows NT command, or batch program to be run.
