DLI Vs BMP

Answer Posted / joshna

DLI- it is Batch processing.
BMP- batch message processing(why batch message? - actually
messages are inputs for online processing but it is a
special type of batch processing whose inputs can be
messages some times/ batch job that runs in an online
region)

there is no point of test,dev or prod for these both tyes
of processing possible in production also
IMS online region will be down when batch processing DLI is
goin on( usvally batch schids run at night time)
BMP processing happens only when MPP regions are running
some times it is possible that BMP processing can run even
though no active MPP region is running

Practical example of BMP:
from morning till evening there may be many onlin
transactions occuring for a particular system.
each transaction updates or modifies database seperately.
instead of allocating locks to database resource all the
changes to database are captured on flat files and at end
of day when onlines are going to shutdown a BMP job is run
with the above said file as input to update all changes to
database at once(specific for a particular system)

Usvally BMP's are run before onlines shutdown.
