Answer Posted / avinash
suppose we have to update 1000 of recrds in my cobol db2
program and my program is running fine and it has updated
999 records but the job gets abended in this scenario my
work is not commited or completed so again i have to submit
a job and again it starts updating from record 1.
so to avoid such scenario commit and rollback is used.
so if we set commit point at every 200 records then it will
update the records in 200*5=1000
so if job abends on 999 records then it rooback to the
records from 800 to 1000.
so cpu time will be less.
