Hi Harish,
I can think anyway to control with sender jdbc. I think the best way is to control from ECC like you said, you can do a job every day with two characteristics, the first to know if the connection is broken or not and the second to do the select only if in the ECC system there are not registers in the insertionDateTime period. Then you can do a proxy - mail to inform you and other responsibles about a possible case of an issue.
Regards.
