DLI / BMP / MPP programs

Post by sikanritun » Tue Jun 25, 2013 11:14 am

Hi,

In IBM book it mentioned that "BMP is submitted through JCL and difference between BMP programs and DL/I programs is BMPs can access and even update "ON-LINE" databases; DL/I programs cannot do this"

Here my question is what is meant by ONLINE databases.

Thanks

Onlne as opposed to Batch - you interact withan online DB via a terminal.

DB2 does not have databases - it has tables. Online systems use CICS /IMS/IDMS or other software and can use straight VSAM datsets or databases. Suggest you start searching the net for basic info like this. Do not get bogged down in detail until you have a general overview, then start drilling deeper.
