Re: Trying to use TRCINT to look at PASE processes

Since you said "sshd" instead of "STRTCPSVR *SSHD", am I safe to assume you
are actually using the sshd command in PASE from a shell?

Aaron,

A most fortutious and interesting caveat you make. Actually, I was
STRTCPSVR *SSHD and it did not work. To get some more information I was
doing "ssh -p 8022 -d" on the command line to start a second session so I
could get all the server debug messages to match up with the client
messages I got from with plink -v -X -p 8022 user@servername

Ironically, it works when running it in debug mode. Now, to be clear Ive
done STRTCPSVR *SSHD/ENDTCPSVR *SSHD many times, logged out of my putty
sessions and made sure all sshd instances were dead with ps between
ENDTCPSVR and STRTCPSVR. I'm sure I don't have to tell you that STRTCPSVR
*SSHD will actually create sshd pids in PASE.

Anyway, I need to run, but I am going to read all that, digest it, and let
you know if it is helpful.

If so, I

recently went through an extensive PASE debugging experience** that gave me
more insight concerning how to debug PASE issues using dbx***.

**Special thanks to Tony Cairns for taking the time. The entire experience

First of all, I'm probably using the wrong tool for this job. What do I
really want to do:
I'm debugging an error when sshd starts up /QOpenSys/usr/bin/X11/xauth. I
want to know whats being piped to it from stdin. If I could know the job
name of any given dead PASE process and do a WRKJOB on it, that will

likely

give me what I need.

Now, what I tried to do is this: TRCINT SET(*ON) TRCTYPE(*PASE)
TRCTBL(PASETRC)

I then typed a few unix command in a ssh session

Unfortunately, I don't see the table get created with this SQL:
SELECT TABLE_SCHEMA || '.' || TABLE_NAME FROM QSYS2.SYSTABLES
WHERE NAME ='PASETRC'

Luckily, I was able to create a spool file with TRCINT SET(*OFF)
TRCTBL(PASETRC)

However, searching for the spool file did not turn up either the

commands I

ran or anything like exec/execv/shell/cmd, which would be what I would
expect the API calls to be to start a process.

So my two questions are:

1. Would this trace even record all the started processes in PASE, and if
not how do I capture them?
2. How do I query the trace information with SQL instead of looking at
spool files.
