[kepler-users] Running Workflows in offline Mode With Kepler

[Srinath Perera]

Hi Shawn, Chad;

Thanks very much for the answer!

Just curious .. Is it a major hassle to do this with kepler 
architecturally? Does Potelmy support offline execution?

Is it possible to do something like following? (I am just thinking aloud 
:) )
1) detach the GUI and the execution
2) add a new logging mechanism that send the status messages to 
persistent notification service
3) set up a services that accept kepler workflow xml files and execute them

Thanks very much
Srinath
