May be you can solve this problem by adding the @ComponentScan annotation in the configuration file @SpringBootApplication @EnableScheduling @ComponentScan(basePackages = “com.mk.service”) @PropertySource(“classpath:application.properties”) public class EnverseDemoApplication { public static void main(String[] args) { SpringApplication.run(EnverseDemoApplication.class, args); } }
You can set event_scheduler=ON in my.ini or my.cnf file, then restart your server for the setting to take effect. Once set event_scheduler will always remain ON no matter whether your server restarts.
As @TheDarkKnight points out, cron has been deprecated in favor of launchd. To use launchd, save the following as com.example.volume.plist in ~/Library/LaunchAgents/: <?xml version=”1.0″ encoding=”UTF-8″?> <!DOCTYPE plist PUBLIC “-//Apple//DTD PLIST 1.0//EN” “http://www.apple.com/DTDs/PropertyList-1.0.dtd”> <plist version=”1.0″> <dict> <key>Label</key> <string>com.example.volume</string> <key>ProgramArguments</key> <array> <string>sh</string> <string>-c</string> <string>set volume 1.7</string> </array> <key>StartCalendarInterval</key> <dict> <key>Hour</key> <integer>23</integer> <key>Minute</key> <integer>45</integer> </dict> </dict> </plist> then … Read more
1) By default, perf stat shows task-clock, and does not show cpu-clock. Therefore we can tell task-clock was expected to be much more useful. 2) cpu-clock was simply broken, and has not been fixed for many years. It is best to ignore it. It was intended that cpu-clock of sleep 1 would show about 1 … 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
SCHED_FIFO and SCHED_RR are so called “real-time” policies. They implement the fixed-priority real-time scheduling specified by the POSIX standard. Tasks with these policies preempt every other task, which can thus easily go into starvation (if they don’t release the CPU). The difference between SCHED_FIFO and SCHED_RR is that among tasks with the same priority, SCHED_RR … 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
The “top” command may help towards this, it does not have CPU-grouped list of threads but rather you can see the list of threads (probably for a single process) and which CPU cores the threads are running on by top -H -p {PROC_ID} then pressing f to go into field selection, j to enable the … Read more
Reading the docs from http://docs.python.org/py3k/library/sched.html: Going from that we need to work out a delay (in seconds)… from datetime import datetime now = datetime.now() Then use datetime.strptime to parse ‘2012-07-17 15:50:00’ (I’ll leave the format string to you) # I’m just creating a datetime in 3 hours… (you’d use output from above) from datetime import … Read more
Create the file <project_root>/bin/say_hello: #! /app/.heroku/node/bin/node function sayHello() { console.log(‘Hello’); } sayHello(); process.exit(); Deploy to Heroku and test it with $ heroku run say_hello then add it to the scheduler with task name say_hello. Explanation Take say_hello.js as an example of a Node.js script that you would normally run using $ node say_hello.js. Turn it … Read more
