Hi,
I am having a problem in understanding the difference between a DLI and a BMP call. Can you kindly throw some lights on the same.

DLI = Data Language/I - you will have to clarify what you mean by DLI
BMP = Batch Message Program - ie a message processor that runs as a batch job

for a IMS, Db2 and COBOL call attach, we use the DLI or BMP calls. I am talking about the differences

In my shop DLI is used if the job doesn't require access to Online databases and transaction. ie the job runs when the online region is down. BMP is used if your job require acces to online transactions and dtabases when the region is up.

In short for me the difference is DLI is used if the online region is down and BMP is used if it is up. Also there are differences in the way a DLI PCB and BMP PCB is defined.

what are the differences between a DLI PCB and BMP PCB??? i came across one difference that: for a BMP PCB, the Plan and the program name must be same whereas for a DLI call, the two can differ. R there any more differences??? if yes then kindly tell me the differences

swapnadeep,

AFAIK there is no such thing called BMP call.

Data Language/I(DL/I) is the IMS data manipulation language, which is a common high-level interface between a user application and IMS. DL/I calls are invoked from application programs written in languages such as PL/I,COBOL, VS Pascal, C, and Ada. It can also be invoked from assembler language application programs by subroutine calls. IMS lets the user define data structures, relate structures to the application, load structures, and reorganize structures.

Batch Message Processing(BMP) program is an IMS batch processing program that has access to online databases and message queues. BMPs run online,but like programs in a batch environment, they are started with JCL. Batch-oriented BMP program is a BMP program that has access to online databases and message queues while performing batch-type processing. A batch-oriented BMP does not access the IMS message queues for input or output. It can access online databases, GSAM databases, and MVS files for both input and output.
