Hi Vadim Klimov:
Thank you very much for your response. From your message I have learnt much.
AS I increase ICM trace level to maximum(3) in transaction SMICM, I got more details about the error :
connection request to < the host configuration> failed ;
IcmJ2EEScheduleFunc: connection to <host>failed.
But what can I do to fix this? Just to add the URL and the IP into my host?
