问题 On Windows Server 2008 R2 I have a batch running every 5 minutes as a Scheduled Task. The batch code calls another batch: cmd.exe /c c:\bin\ftp_send.bat (this does a lot more than ftp). When this batch was invoked on Windows Server 2003, it ran and stopped when done - usually less than 4 minutes. On 2008 it does not stop - status on Refresh is always 'Running'. It finally reads 'Ready' after my configuration in Settings is triggered to 'Stop the task if it runs longer than: 30 minutes'. Also

问题 First of all, a short introduction to the application. We are developing a wireless sensor that sends data over BLE using a single characteristic (hardware limitation) to a client UWP app. The messages vary in size from under 20 bytes, to 512 bytes. The messages consist of a start character (start_char), preamble, data, CRC for detecting errors and an end character (end_char). If these special characters occur inside the message, they are escaped. Message processing on the client side

问题 This is the php implementation of the same scheduler. I made this php implementation, because I thought I have issue with nodejs async nature. Unfortunately, they have the same issue. This may indicate that something wrong with my logic or mysql. I had hard time to figure why. I have 10 commands stored in schedule table. When the day code, hour and minute are matching up with current day code, hour and minute. Those commands will copy into command table. This relies on the scheduler I am

问题 I am trying to understand linux kernel code for task scheduler. I am not able to figure out what is goodness value and how it differs from niceness? Also, how each of them contribute to scheduling? 回答1: AFAIK: Each process in the run queue is assigned a " goodness " value which determines how good a process is for running. This value is calculated by the goodness() function. The process with higher goodness will be the next process to run. If no process is available for running, then the

问题 I am running a task in web2py scheduler. The task is completing successfully but web2py says that the task is still running until timeout expires and then logs the task with a status of TIMEOUT .

问题 In operating systems of supercomputers, which handles a big quantity of tasks at the same time, is there any situation when SJF policy is taking longer than FCFS policy, speaking of waiting time metric? It can be assumed that more than one core are present in the system. 回答1: First I thought that it is not possible, then I took some time and finally arrived at this result: Yes it can be. Suppose that ready queue is filled with processes with equal burst times(all = x): Process Burst time P1 x

问题 So the setup on this WinServer 2012 R2 64bit is: Windows Task Scheduler -> cscript .vbs file -> opening excel and run a sub in the main module This runs fine in the background when I double click the .vbs file, but when I trigger the .vbs via the task scheduler, excel opens, but doesn't load the file or run the sub (not sure which). The task runs under an domain user that has administration rights on the machine. I use the same user when i try clicking on the .vbs Code that is being run, in

问题 I want to schedule sending mails using Rufus-scheduler in a Rails app deployed on Heroku. My code looks like # config/initializers/scheduler.rb require 'rufus-scheduler' s = Rufus::Scheduler.singleton s.every '11h30m' do # here I put my sending mail task (already tested, and works well) end But nothing happened, and I can't figure out the issue based on my logs I suspected some points: 1- Is my procfile correct ? Do I need something else in order to use Passenger ? will the classic webrick
