Re: PHP Identifying QSQSRVR Job for Debugging

Michael,

The trick to debugging RPG programs from stateless toolkit jobs (that run in QSQSRVR) is the ‘*debug’ control key. Instructions below excerpted from my PHP toolkit presentation (http://www.alanseiden.com/presentations/ <http://www.alanseiden.com/presentations/>):

1. Add the following line to your PHP script before the program call to be debugged. $toolkitConn should be your toolkit connection object.

$toolkitConn->setOptions(array('customControl'=>'*debug'));
Run your script. The script will "hang" while it waits on #2 below...(move to green screen 5250 for steps 2-10)

2. A MSGW inquiry message in DSPMSG QSYSOPR will be generated by the toolkit.

3. Note the job information (number, name, user) provided in the MSGW.

4. STRSRVJOB using that job information as parameters.
5. STRDBG with the program and library you wish to debug.

6. Answer the MSGW. Any answer will do--"G" is fine.
7. The RPG program source will appear in debug mode in your terminal, ready to step through, allowing you to inspect variables, etc.
8. When done inspecting and stepping, let the RPG program complete (using function keys indicated on screen).
9. ENDDBG
10. ENDSRVJOB

I need to occasionally debug the PHP script->i program interaction,
especially when I need to see parameters being passed or to trace logic
flow. When I run in stateful more, I'm able to use STRSRVJOB on the Toolkit
job, and then STRDBG on the program or service program. However, when I use
stateless mode, the job uses a QSQSRVR job and I don't know which one will
be used.

I was thinking I could have the PHP script send a SNDMSG command with an
*INQ so I could identify the QSQSRVR job being used. This works, but the
PHP script doesn't 'pause' and wait for the response. So then I thought I
could use SNDPGMMSG, specify a key variable, then use RCVMSG for an *INQ
type with that MSGKEY.

Anyone have any hints for this type of debugging interaction? Cross posted
to midrange and web since it has a MSG question as we as a PHP technique.
Thanks!
