Re: How to debug web service RPGLE program

If you have the new ACS, then you will find the system debugger in the
tools, Or for older ACS it is in "Run SQl Scripts" -> Run -> System debugger

It will let you open all kinds of programs to debug also service programs (
and PASE) and it can connect to both interactive sessions and batch jobs.

Using SEP debugging in RDi is quite straightforward - lot of tutorials and

Using SEP in Green Screen STRDBG isn't - but I found a piece from 2012
describing the process quite well:

https://www.itjungle.com/2012/10/03/fhg100312-story01/

Never used it, 'cause I'm a RDi-guy - but from what I read it quite a bit
of a PITA to use 2 emulation sessions to debug one batch process. But it
seems to work.

Essentially SEP debugging sets a "break point" on a program/service
program on the object level. Usually conditioned with a user profile. If
that user profile is executing the specific program, the job is suspended,
until a debugger is hooked onto the job.

The most important thing is to remember, that the SEP is hanging on the
real object - so if you recompile the program, the original object is moved
to QRPLOBJ - and the SEP is still hanging on THAT object, and not on the
newly created one.

In RDi you simply update the SEP - I assume that you have to ENDDBG and
STRDBG/SBREAK again on the green screen.

Liam,

SEP (Service Entry Points) basically pause the program when it reaches
the breakpoint and then sends the correct STRSRVJOB command to you.

The system debugger and RDi will automatically receive the STRSRVJOB
command (you don't even see it) and automatically start the debugger at
that point. In green-screen you have to do it manually, but in either
case it's handy.

Imagine a situation where your program starts in a batch job, runs, then
ends. How do you debug it if you don't know the job id, and the job ends
immediately if something doesn't stop it?

SEP makes that easy because it stops the program AND either opens the
debugger (in GUI) or sends you the job id (in green-screen) so you don't
have to worry about trying to figure it out somehow. It saves a lot of
effort. Especially with network servers where it's normal for a new job to
be spawned, a program run, and then the job ended.

If you read the rest of the thread, there are articles about how to use
it, etc that are linked.

Sorry for my ignorance, but what is SEP?
I’m all green screen and use STRSRVJOB and STRDBG all the time

Service Entry Points are available in all of:

- Green Screen Debugger

- System Debugger (which you were just telling us about)

- RDi debugger


Sadly, VS Code does not (yet) have support for SEPs. Personally I find
the System Debugger so buggy that it isn't usable, and I find RDi slow
and cumbersome. So I typically use the green-screen debugger. I use
SEPs almost every day, and they've been around for ages. I find it
odd
that soooo many people in this conversation don't know about them.

The System Debugger is integrated in iACS and completely independent
from RDi - with this you can remotely debug any job.
I don't know if the "service entry point" debugging is RDi exclusive,
but I didn't find it anywhere else until now.

I have a web service & I need to be able to put the job into debug.

I remember that RDi could put a put a like on a program such that
when
a
job calls it that job is put into remote debug. I don't have RDi. ☹

Is there a way I can do it without RDi. Maybe VScode?
