If the problem you’re having is with Execution Policy, then you can also set the execution policy of a specific invocation of PowerShell. This is what I usually do when executing PowerShell through a scheduled task: powershell.exe -NoProfile -NoLogo -NonInteractive -ExecutionPolicy Bypass -File \\path\to\script.ps1 Why? -NoProfile This ensures that you don’t rely on anything in … Read more
Change your Action to: powershell -noprofile -executionpolicy bypass -file C:\path\event4740.ps1 On a Windows 2008 server R2: In Task Scheduler under the General Tab – Make sure the ‘Run As’ user is set to an account with the right permissions it takes to execute the script. Also, I believe you have the “Run only when user … Read more
You can use the cancel() method on Future. From the javadocs of scheduleAtFixedRate Otherwise, the task will only terminate via cancellation or termination of the executor Here is some example code that wraps a Runnable in another that tracks the number of times the original was run, and cancels after running N times. public void … Read more
Upgrade to airflow version 1.8 and use catchup_by_default=False in the airflow.cfg or apply catchup=False to each of your dags. https://github.com/apache/incubator-airflow/blob/master/UPDATING.md#catchup_by_default
Just use launchd. It is a very powerful launcher system and meanwhile it is the standard launcher system for Mac OS X (current OS X version wouldn’t even boot without it). For those who are not familiar with launchd (or with OS X in general), it is like a crossbreed between init, cron, at, SysVinit … Read more
Try adding a Thread.sleep(1000); call within your run() method… Basically it’s the difference between scheduling something based on when the previous execution ends and when it (logically) starts. For example, suppose I schedule an alarm to go off with a fixed rate of once an hour, and every time it goes off, I have a … Read more
This works. The key is to have the task itself (after it completes) schedule the next occurrence of the task. import java.util.Timer; import java.util.TimerTask; public class TaskManager { private Timer timer = new Timer(); public static void main(String[] args) { TaskManager manager = new TaskManager(); manager.startTask(); } public void startTask() { timer.schedule(new PeriodicTask(), 0); } … Read more
The purpose of having separate dedicated threadpools is so that an activity doesn’t get starved for threads because other activities took all the threads. If some service has its own threadpool then it is assured of having a certain number of threads at its disposal and it’s not as sensitive to demands made by other … Read more
Calendar today = Calendar.getInstance(); today.set(Calendar.HOUR_OF_DAY, 2); today.set(Calendar.MINUTE, 0); today.set(Calendar.SECOND, 0); // every night at 2am you run your task Timer timer = new Timer(); timer.schedule(new YourTask(), today.getTime(), TimeUnit.MILLISECONDS.convert(1, TimeUnit.DAYS)); // period: 1 day
The difference is best explained by this non-Android documentation: Fixed-rate timers (scheduleAtFixedRate()) are based on the starting time (so each iteration will execute at startTime + iterationNumber * delayTime). In fixed-rate execution, each execution is scheduled relative to the scheduled execution time of the initial execution. If an execution is delayed for any reason (such … Read more
