Schedule for BPM

Hi All:

I have a BPM which takes JDBC records(JDBC sender), is poll for 5 mins(300 sec) in my receive step. In my BPM the time taken to process the records is say more than 5mins.

My query is I donnot want the next batch of records to be processed by the BPM than the first batch is processed by the BPM.

Thanks
