Re: INFO: IBM i System Debugger not stopping on breakpoints

Glad you liked my post. I just wanted to get to the grounds of it.
(My professional life goes back to IBM System/38 serial number #78 (an IBM internal machine from 1980/81 (5381) with 3375 external DASD) when I was a youngster).

Pity though, that we can't do much about this System Debugger behaviour on PUB400.
I simply can't think of any way to change that.

The Java debugger component tes.jar is not part of the open source of JT400 (or JtOpen) either,
otherwise I would have looked at the source code; I made few attempts to trace it with WireShark, but it's a lot of work.
My gut feeling is, that the MATPRATR might not even be absolutely necessary, but it's no more than only a gut feeling.

Excellent research! Thanks.

(But I bet the only fix, if any, will be to the documentation.)

INFO: IBM i System Debugger not stopping on breakpoints
=======================================================

This is a post inspired by two past posts which did not find a correct solution:

"ACS System Debugger doesn't want to work" https://archive.midrange.com/midrange-l/202210/msg00244.html
and
"System Debugger" https://archive.midrange.com/midrange-l/202306/msg00321.html

Both posts describe the problem that System Debugger wouldn't stop on breakpoints (with the breakpoints briefly flashing in yellow).

I also observed this, on a local V7.2 system and on PUB400 V7.5

Quick Answer:
-------------

The debugging user needs *JOBCTL special rights for this to work.

This applies to debugging option "Submit and debug program in batch job"

N.B.:
PUB400 won't allow *JOBCTL - for a good reason, see below - so this won't work until (hopefully) IBM fixes this.
