Question

I am using Jboss5.1.x, EJB3.0, Quartz 1.8

I have System which is being activated at specific time(surrounding that time).
The system should work once in a day.

I am setting value in a database which mention the activation time and every hour the system is pulling that value to check if the current time is matching the value (in case it is the system will activate itself).
This time has to be changeable in the future dynamiclly.

Now this technic gives me a headache, since I need to do some Math calculations (in case the current time has passed in couple of mins I still need to activate the system.
more over I need to take care for a case the system already activated so it wont be activated again in the same day (due to a time mistake caluclations.)

I could think about other technic which pulling the database once in couple of days to check if the activiation time has ever change(in this case I wont need to pull every hour, but in other case i am not sure Quartz can re-schedualre it’s triggers while it’s running)

any ideas? solutions?

Thanks,
ray.
