A "D SSI,FUNC=9' command may give you a clue where to look.
Perhaps you only have a few listeners. You could also get that
information from IPLINFO, ShowMVS or MXI.
I think the official answer is that you open a PMR or Tech Question
with IBM ad they will give you a trap to run a SLIP trace. The
module where the trap is set is OCO so you can't guarantee what
works in one release will work in another.
But given that caveat, ...
Here is the SLIP trap for z/OS 1.6 (I think).
It traps entry and exit of of SSI function code 9 (WTO) and function
code 10 (command). You can probably eliminate the command test.
The following is from an exec that issues the SLIP command. You
would obviously omit the quotes if you are entering it by hand.
"SL SET,IF,LPAEP=(IEFJRASP,8E0,8E3)"
"DA=(1R?+6,EQ,0009,AND,(1R?+10?+4?+20,EQ,"m1",+24,EQ,"m2"),"
"OR,(1R?+10?+4?+20,EQ,"c1",+24,EQ,"c2"))"
"A=TRACE"
"TD=(STD,REGS,1R?,+1C,1R?+8?,+24,1R?+10?,+14,1R?+10?+4?,+160)"
"END"
where
m1 is the hex of the 1st 4 characters of the message id
m2 is the hex of the 2nd 4 characters
c1 is the hex of the 1st 4 characters of the command
c2 is the hex of the 2nd 4 characters
I was waiting for you to reply. I remembered the problem you had
a while with this (Netview?). Then I thought about it and remembered
one of my coworkers recently opened a PMR because some unix
messages were not getting written to /dev/console on a few LPARs.
Anyway, the SLIP below was for z/OS 1.8 and the offsets look the same.
MSGID was BPXF024I.
SL SET,IF,LPAEP=(IEFJRASP,8E0,8E3),DA=(1R?+6,EQ,0009,
1R?+10?+4?+20,EQ,C2D7E7C6,
+24,EQ,F0F2F4C9),
A=TRACE,TD=(STD,REGS,
1R?,+1C,
1R?+8?,+24,
1R?+10?,+14,
1R?+10?+4?,+160),END
