The following list presents the different types of processes in order of importance (the first process is most important and is killed last): Foreground process Visible process Service process Background process Empty process Note: Android ranks a process at the highest level it can, based upon the importance of the components currently active in the … Read more
scheduler.getCurrentlyExecutingJobs() should work in most case. But remember not to use it in Job class, for it use ExecutingJobsManager(a JobListener) to put the running job to a HashMap, which run before the job class, so use this method to check job is running will definitely return true. One simple approach is to check that fire … Read more
From other forums: Although dbms_job still exists in 10g and 11g, Oracle recommends the use of dbms_scheduler in releases 10g and up. No new features are being added to dbms_job and you will likely quickly run into its limitations. dbms_scheduler is more robust and fully-featured than dbms_job and includes the following features that dbms_job does … Read more
I’ve figured out the answer to my question, so I thought I’d add it here. Below is the patch that will add a new scheduler to the 2.6.34 vanilla kernel. Right now, I’ve only compiled the kernel. I fully expect running a system with this EXACT patch will cause it to crash — so use … Read more
I Think that you could create a simple batch script that will launch your program in this way : @echo off REM Eventually change directory to the program directory cd C:\Users\User1\Documents\NetBeansProjects\Facebook\dist\ REM run the program “C:\Program Files\Java\jdk1.7.0\bin\java.exe” -jar “C:\Users\User1\Documents\NetBeansProjects\Facebook\dist\Facebook.jar” Copy it into the notepad and save as java_script.cmd and then schedule this script instead of … Read more
You can test the actual method execution using the regular JUnit, but to test if the @Scheduled(cron = “0 * * * * *”) you specified is correct you can use: @Test public void testScheduler(){ // to test if a cron expression runs only from Monday to Friday org.springframework.scheduling.support.CronTrigger trigger = new CronTrigger(“0 0 1 … Read more
Scheduler tasks should be placed only in Global class. Create two tasks, schedule only once first with initialDelay = 0 milliseconds. For the second task, you need to calculate seconds between current DateTime and next planned occurrence (ie. tomorrow at 8:00 o’clock) using common date/time classes, then set this difference as initialDelay and also set … Read more
At a high level, there are two separate mechanisms to understand. The first is the kernel entry/exit mechanism: this switches a single running thread from running usermode code to running kernel code in the context of that thread, and back again. The second is the context switch mechanism itself, which switches in kernel mode from … Read more
Use Scheduler when you need a browser to complete whatever it is currently doing before you tell it to do something else. For example: myDialogBox.show(); Scheduler.get().scheduleDeferred(new ScheduledCommand() { @Override public void execute() { myTextBox.setFocus(); } }); In this example, focus will not be set until the browser completes rendering of the dialog, so you tell … Read more
This might be too late for your work, but here is how I did it. I want something run everyday at 1AM – I believe this is similar to what you are doing. Here is how I did it: CREATE EVENT event_name ON SCHEDULE EVERY 1 DAY STARTS (TIMESTAMP(CURRENT_DATE) + INTERVAL 1 DAY + INTERVAL … Read more
