Answer / s
The data communication PCB(IOPCB) is automatically included
by the IMS at the beginning of the PSB for an MPP or BMP.
This default data communication PCB is used to insert O/P
messages to the originating terminal. ALTPCB is coded to
identify alternate destination for the O/P messages, say
printer.
/DIS PGM will tell whether its online or batch. If the pgm
is not found, it is purely batch. Otherwise its an MPP or
BMP.

Answer / prashant
i donot agree. To find out wether is batch or online , you
should type the following terminal command on IMS SCREEN -
/DIS PGM 'PRGRAM NAME'

One more ways is like, by seeing PSB definition, if any of
the GSAM files used then it will be batch IMS. but this not
true all the time

Answer / luiz
For IMS, the answer to that question really depends on your definition of batch and online:
If you consider Online as purely interactive transaction processing, as performed by a MPP, JMP or IFP region, then the best way to clear the doubt is to display the program, see if it has one or more transactions associated with it, and look if the class(es) of said transaction(s) is(are) defined in the executing MPPs of the IMS. If there's a transaction but its class is not defined on the MPPs, your program is probably used in batch processing by a transactional BMP; if the PGM has no associated transaction, then it is used by a non-transactional BMP. Any other IMS programs that cannot be displayed are batch DLI ones.
On the other hand, if you consider Online as any processing that can only happen when IMS is up, then if your program can be displayed, it is an online program - be it for a BMP, MPP, JBP, JMP or IFP. Any program not defined in IMS is an offline program meant to be used in batch by a DLI job.
