Hello Chao,
Please provide more information on the issue you are experiencing. Are you getting an error message of some kind? Also we'd like to see the Scheduling Log from the Scheduling server
and the Execution server. See the first point
here on how to load the log viewer and export it. See the rest of that article for other fixes to common Scheduling issues. Thanks for providing the information we need to best assist you.
Regards,
Plamen
