Is it possible to trace an SDLC line attached to the 4-Port
Multiprotocol-Adapter even if SNA Services is unable to establish
a link on that line? Tracing the attachment didn't get me the
desired result (i.e. the trace file was empty), and I was unable
to achieve anything by trying to trace the MPQDD. Am I overlooking
something obvious here? If so, or if I missed anything in the
documentation, feel free to flame me. If not, maybe some kind
soul in Austin could point out a way for doing this.
My current problem is to get my Model 530 to talk to our /370
system to which it is hooked up via an 3725 and an SDLC line.
Used to work fine in the past whe I used a dialup line, but now
that we have a connection using two inhouse-modems, nothing works.
Definitions on the VTAM side look fine, as do the definitions
in SNA Services on the /6000. I would like to make absolutely
sure that we did everything right before we start bothering the
guys at defect support -- hence the need for a trace on the AIX
side, as low-level as possible, since (as mentioned earlier) an
Attachment Trace produces absolutely no data. (Yes, the cables
are ok, the poll from the 3725 can be traced to the /6000
connector and so forth.
On a side note: Is it a known problem with 3002 that the use of
pagespace is creeping upward over time? Our 530 usually uses
about 30% of pagespace upon system boot (with no load, that is),
and it went up to about 45% 10 days later (again with no real
system load). At least that's what lsps tells me -- maybe it is
pulling my leg. Oh well.
I would appreciate any comments on the above problem(s). Thanks
in advance,
Chris.

One choice would be to turn on the VTAM Internal Trace (start with the CIO, MSG, and SSCP options), and see what happens after VTAM does SIO; see VTAM Diagnosis (LY30-5601 for V3R2) for details. Decrypting the ERP entries requires 9370 Telecommunications Subsystem Description and Reference (SA24-4041), or equivalent for your processor.

I prefer to debug communications with an independant line monitor. Something like an ARC Interview 7000 which is kind enough to decode and trace SNA or SDLC protocol. (You could look at the raw bitstream - which I painstakingly did before receiving the software for the ARC). Mike Neverisky philabs!trintex!neverisk
