We're implementing a Job via JobScheduler for background loading of data. The job will fire about once a day. What tools are available for us to test this functionality (possibly ADB)? Use cases are to be able to simulate the conditions required for a Job to be run or to just say specifically "Run this job" as part of our automated test suite. tim Right. Henning and P4u144 set me on the right track to answer this in more detail. Identify all registered jobs Identify your task with the adb shell dumpsys jobscheduler command.

DBMS_JOB vs DBMS_SCHEDULER

What is the difference between DBMS_JOB and DBMS_SCHEDULER ? 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 not have : logging of job runs (job history) simple but powerful scheduling syntax (similar to but more powerful than cron syntax) running of jobs outside of the database on the operating

EJB @Schedule wait until method completed

I want to write a back-ground job (EJB 3.1), which executes every minute. For this I use the following annotation: @Schedule(minute = "*/1", hour = "*") which is working fine. However, sometimes the job may take more than one minute. In this case, the timer is still fired, causing threading-issues. Is it somehow possible, to terminate the scheduler if the current execution is not completed? Arjan Tijms If only 1 timer may ever be active at the same time, there are a couple of solutions. First of all the @Timer should probably be present on an @Singleton . In a Singleton methods are by default

问题 How to check if scheduled Quartz cron job is running or not? Is there any API to do the checking? 回答1: 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 times are different: public static boolean isJobRunning

Triggering spark jobs with REST

问题 I have been of late trying out apache spark. My question is more specific to trigger spark jobs. Here I had posted question on understanding spark jobs. After getting dirty on jobs I moved on to my requirement. I have a REST end point where I expose API to trigger Jobs, I have used Spring4.0 for Rest Implementation. Now going ahead I thought of implementing Jobs as Service in Spring where I would submit Job programmatically, meaning when the endpoint is triggered, with given parameters I
