Hi manoo,
im a IMS beginner and I hope that my explanation is correct.
BMP Batch: While BMP batch are the databases you process while batch
registered to IMS and online processing (MPP) is possible.
DL/I Batch: While DL/I Batch you have to stop the database and deregister from IMS (I hope this is correct). At This point only your DL/I Batch Programm can access the database.

DLI - you can access(read) a database which is allocated to IMS anytime but you cannot update it whilst it is allocated.
BMP - you can read and/or update a database whilst it is allocated to IMS |

afaik, this is not necessarily true. It depends on how you set up the data sharing.
A BMP runs under control of the IMS DB/DC. Effects: BMPs are under control of the IRLM (internal resource lock manager) and you can assign a transaction code to a BMP etc...
A DLI does not run under control of IMS DC and therefore cannot use IRLM. I think THIS is why many shops don't allow updates from DLI programs... |
