BMP is a Batch message Processing that means the online
databases are accessed through batch schedule that is by
submitting a JCL. While DL/I can be run to access the
databases while allocated to online or offline or even to
your own copy of database datasets.
But In general some shops only allow DL/I when the
databases are down and in the mainframe legacy environment
if a shop uses DL/I then it is run in the batch night
schedules when the databases are offline.
Many shops have converted DL/I to BMP for many reasons that
include easy maintenance ; no need for batch backout etc.
It is fair and easy to have online(MPP) and BMPs ...but if
the user wants to run test against his own dataset then
DL/I serves better.
Keep in mind about the different flaours of BMP also.
