Is there any difference between DLI and BMP? Or BMP is just type of processing which can be implemented using DLI techniques.

I know this is basic query and Please help me to clear concepts.

Hello,

I don't "do" ims, but you can find all of the info you want here:

At the top of the page is a link to "IBM Manuals" which has links to many manuals you will use often.

Code:

MPP (Message Processing Program)
   For Online programs( IMSDC) only.
   PSB used by a MPP program cannot be used by another programs simultaneously.
   Cannot run on Individual partitions.

BMP (Batch message processing)
   For batch programs only
   PSB used by a BMP program cannot be used by another programs simultaneously.
   All partitions specified in PSB will be allocated whether used by program or not.
   Cannot run on Individual partitions.
 
DL/I
   It can be used as Interface between MPP and Database OR BMP and Database
   For batch DL/I job it can access database directly
   PSB of DL/I job can be used by another jobs simultaneously
   It can run on Individual partitions.

There is no difference in programming the application. You can have an application program running as BMP at one time and as a DLI job at another.

BMPs are dependent on the IMS master region to be running. If DL/1 online databases are used they need not be allocated to the job, they are accessed through the IMS region, and they need to be online.

DLI jobs, on the other hand, are establishing the IMS environment locally, so they are not dependent on the master region running. DL/1 databases need to be taken offline from the messaging regions and allocated specifically to the job for usage. Generally DLI jobs have more overhead running for each job than a similar BMP job.
