job-scheduling

问题 I have a procedure which is being called at server side and I need to make it asynchronous. So I have created another proc in which I'll create Oracle'Job and this will call that proc in its job_action. Proc is: PROCEDURE upload_csv_file_data(a_what_to_do IN VARCHAR2, a_logon_user IN VARCHAR2, a_csv_data IN CLOB) IS v_job_action VARCHAR2(32676); /*v_log_error VARCHAR2(32676);*/ v_job_name VARCHAR2(100); BEGIN v_job_action := 'process_csv_file_data(''' || a_what_to_do || ''',''' || a_logon

问题 I'm looking for some guidance in getting a Job Scheduler setup for use INSIDE of my MVC3 website. I've been looking at Quartz.NET for this, but am having trouble finding guidance online as far as the setup to make sure it's running when the website is. With the information above taken into consideration. I'm aware of a couple of the "drawbacks" to setting up a job scheduler inside of IIS. The jobs that I'm looking to setup are simple cleanup jobs where timing is rather unimportant so if IIS

问题 I am running Quartz.NET as a service and I add my jobs directly in the quartz-jobs.xml file. So in order to add and delete jobs and triggers I deal with Xml and not the normal functions. I would like to know how can we get the next fire time of a trigger just by looking at its cron expression? 回答1: You can get the next fire time from given cron expression: var expression = new CronExpression("0 26 13 17 10 ? 2015"); DateTimeOffset? time = expression.GetTimeAfter(DateTimeOffset.UtcNow); 来源：

问题 I am implementing Firebase Jobdispatcher with trigger time specified between 10 to 20 seconds. This is my code to schedule a job: public static void scheduleCompatibleJob(Context context) { FirebaseJobDispatcher dispatcher = new FirebaseJobDispatcher(new GooglePlayDriver(context)); Job myJob = dispatcher.newJobBuilder() .setService(DataTrackerJobService.class) // the JobService that will be called .setTag("api_trigger") .setRecurring(true) .setLifetime(Lifetime.FOREVER) .setTrigger(Trigger

问题 In my android app I have created a function that updates some fields in SQLite database, now I run this function manually and it is doing the job, but I want to run this function automatically once in a month.

问题 I have got a job scheduling problem. We are given start time, time to complete the order, deadline. It is given that start time + time to complete <= deadline . I have also been given the loss that will occur if I am not able to complete the job before the deadline. I have to design an algorithm to minimize the loss. I have tried changing the standard algorithm of dynamic programming for maximizing the profit in job scheduling but to no success. What algorithm can I use to solve the question?

问题 Alright, I think the title is pretty self-explanatory...I have to use the WorkManager api to schedule a notification that will be displayed every time the device is connected to the internet and is charging(plugged-in). I managed to create a worker and make it display the notification, but the issue here is that it only shows the notification once. After that even if I disconnect/re-connect to wifi and unplug/plug the cable, it won't show the notification. val notificationTriggerConstraint =

问题 I have a queue of 500 processes that I want to run through a python script, I want to run every N processes in parallel. What my python script does so far: It runs N processes in parallel, waits for all of them to terminate, then runs the next N files. What I need to do: When one of the N processes is finished, another process from the queue is automatically started, without waiting for the rest of the processes to terminate. Note: I do not know how much time each process will take, so I can

问题 I'm using Sun Grid Engine on my ubuntu 14.04 to queue my jobs to be run on my multicore CPU. I've installed and set up SGE on my system but I have problem when testing it. I've created a "hello_world" dir which contains two shell scripts named "hello_world.sh" & "hello_world_qsub.sh" first including a simple command and second including qsub command to submit the first script file as a job to be run. Here's what "hello_world.sh" includes: #!/bin/bash echo "Hello world" > /home/theodore/tmp
