DDM file makes Work process run and run forever until R3 stops

Klaus: I believe we're doing DDM over I/P. Is that a better solution for you?

Hi All,

DDM file makes work process run and run forever until R3 stops

I have discovered a problem with DDM files and R/3 work processes (and AS400
in general)

Here is the case:

I have two AS400 mashines one lets call it SAP and one lets call it RPG
(with old systems and files on)

When I want to read a file from SAP that recides on RPG one can use DDM
files - this all works fine but ----

As most old AS400 technicians know you need a line/controler and device to
connect to the other maschine.

To make this you most connect a mode (by default you can use the IBM
supplied mode BLANK)

This mode normaly is set to have max 8 conversations running.

This was my problem - suddently someone tried to open a ninth DDM session to
RPG from inside SAP (a embeder CPYF in an ABAB) - then the work proces
"hangs" (runs and runs).

Problem is that a workprocess (job) does not release such a session until
the job (workprocess) ends - so when all 8 are used the workprocess "stops"
with status ICFW - this status meaning waiting for a free session - but this
does not occur until R/3 stops.

Fast sollution is to change the mode description to something higher then 8
(max value is 512) - better sollution is to implement a CHGJOB DDMCNV(*DROP)
in the abap.

Regards
Klaus Lindegaard
