Every day the sequence is prefixes with different number and generating the job ids from one.
Could you provide an example of the job-id's being generated. Where are you seeing these different id's? In the Job_Instance_Table?
I want the behaviour to start the sequenece number from 1 and continues by incrementing by 1 for every new job.
This is supposed to be the default behavior. It should work that way out of the box
Is any setting at xml configuration level or database level needs to change ?
Your config looks fine.
