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 Shawn Bowers wrote: > > Just a quick note: One way to achieve this functionality (in a very > simple way) is to run Kepler directly at the server (e.g., using > ptexecute) as a background process ...
