Answer / mahesh vasudevan
When the DL/I job abends then it might leave an update that
could be partial...and hence it requires a backout to the
last commit point. To undo the partial update the batch
backout utility is run so that you get a valid checkpoint
from which the job can be restarted with proper parameters
and log tapes.

Answer / jak
1)The utility is used to recover databases to a point before
a program was initiated, or to a checkpoint or sync point.
2)It backs out all updates for all DL/1 data sets performed
in that time period.
That why for batch backout utility we need the job name,PSB.
It is run as a normal IMS batch job and uses the program
specification block (PSB) of the program whose
updates are to be backed out.
