Re: How to debug web service RPGLE program -- RPG400-L

Using SEP debugging in RDi is quite straightforward - lot of tutorials and articles by the "usual suspects".

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?
