scheduled-tasks

问题 I am creating an @Scheduled task to run every 5 seconds. As has been a problem in other questions, my task is running twice! I have looked at other questions, and read the applicable documentation here, but I have not been able to figure out the problem. I know that two seperate instances of my @Scheduled class are getting instantiated when I start my tomcat server. I have also figured out when they are instantiated in reference to my log file. One associated with this log line : INFO:

问题 I knew about the possibility to get backup db using SQL server agent, but I was curious to know if we can have a backup script (like batch file) that just runs in windows and gets automatic backup according to the schedule that we define? I think for the next part we can use windows task schedule (or crontab) for run the backup script job routinely, but the most important thing is to know: is it possible to login via SQL and backup the DB just using a batch scrip file (that there not be any

问题 if we have 50 cloudlets/tasks and 1 virtual machine (vm) how can we make vm to run for specific time in order to apply RR method and cloudelts are run in time slice or quantum 回答1: In fact, CloudletSchedulers in CloudSim don't implement the concept of time slice/quantum. If you need to assess Cloudlets' preemption process, you can check CloudSim Plus, it's a full-featured, state-of-the-art, completely re-engineered and actively maintained CloudSim fork. It provides an implementation of the

问题 I am building a server-based application that runs a series of automated scripts (i.e., "bots") in the cloud. I have provisioned an instance of Heroku Scheduler to automatically run one of those scripts as shown in the below Fig. 1. Fig. 1. Screen capture of Heroku Scheduler dashboard As you can see from Fig. 1., the scheduler is supposed to run the following command node src/spiders/clusters/auctionMacro.js every ten minutes. Which appears to be happening as expected as shown below in Fig 2.

问题 I am working on making a cron job in Java. I want to run a particular task every week, month, three month, six month and nine month. public Interface interfaceA { public String abc() throws Exception; } public class TestTaskA implements interfaceA { @Override public String abc() throws Exception { // some code } } I am running it like this - TestTaskA testTaskA = new TestTaskA(); testTaskA.abc(); I want to run TestTaskA every week, every month, every three month, every six month, every nine

问题 I have written in my console application a line System.IO.Path.GetFullPath("ApplicationSubDirectory") to get application directory file system path. I build this application and installed exe in my system. exe has been installed in c://ProgramFiles/AppFolder/ directory. When I execute exe then I got valid path like c://ProgramFiles/AppFolder/ApplicationSubDirectory . But when i scheduled this exe to run dailly basis in windows scheduler. Then I am getting wrong path. This returns me path of

问题 I am running a bunch of simulations on several (non-equivalent) client machines. In order to ensure that each simulation is run only once, the clients connect to and schedule a task on a linux server. The linux server runs the scheduled task, which ssh 's back into the client and schedules a run of the next simulation to be run. Since some of the clients run windows XP (running cygwin), part of the scheduling script on the client side checks if the client is running linux or cygwin and
