Answer Posted / milky
Checkpoint-Restart logic is used when your program performs
a large number of database updates or inserts. If you want
to process and insert say 1000 records in a table, and your
program abends at 726th record, then if the checkpoint
frequency has been set to 100, then, on restart the program
will start processing from 701th record as each processing
of 100 records results in a COMMIT.
