515.0. "Login times out, where is TRACE utility???" by OSLAGE::AGE_P (Aage Ronning, Oslo, Norway, (DTN 872-8464)) Sat May 03 1997 00:25

X25 1.0g DECnet OSI V6.3 and OpenVMS Alpha V6.2-1H3
---------------------------------------------------

Customer has VAX multihost with several VAX access nodes working OK. The only
Alpha connected to this have BIG problems when trying to use X29.

One or two users can normally connect to it but then calls will be disconnected 
after PW is typed in(or in Username if you keep on typing 50-60 characters.

Example:


 SNORRE>  set h/x29 <customer_dte_#>

%PAD-I-COM, call connected to remote DTE

Username: FIELD
Password:
Error reading command input
Timeout period expired
%PAD-I-CLEAR, call being cleared at request of remote DTE
PAD usage statistics:
  Elapsed time: 00:00:25.88               CPU time:     00:00:00.20
  Buffered I/O: 102                       Direct I/O:   70
  Page faults:  75
                     
YES, I HAVE typed <Return> after the PW.

The customer claims he could get 6+ successful logins on an idle system, but we
never succeed more than one or two during normal working hours so it seems like
it could be a resource problem of some kind. The Alphaserver is a 4100 with 2GB
of memory with about 700 processes during normal working hours.

I've traced the login on my local system and on the Multihost VAX system at
customer site and all characters seems to be send and received OK(including the
<Return>). BUT I'm unable to trace it on the Alpha because NETTRACE.EXE is not
there and when renaming the existing NETTRACE_TV.EXE it complains about some old
shareable images in SYS$LIBRARY. It seems like it's a mess of new and old images
related to NETTRACE on the Alpha. 

Could anyone tell me how I could use TRACE on the Alpha?

Any hints on how to troubbleshoot the login problem?

515.1 DEcnet PLUS trace utility is CTFOZROCK::HARTWIGArthur Hartwig, TaN Engineering-AustraliaSat May 03 1997 08:1615
    In the DECnet/OSI environment CTF is the trace utility. CTF is invoked
    by the command TRACE.
    
    This is all written up fairly clearly in the DECnet/OSI documentation.
    
    The command TRACE START/LIVE "X25GAP CIRCUIT *" will possibly provide
    some useful information. You might also look for network errors causing
    timeouts and re-transmissions. Do all the systems have sufficient
    non-paged pool?
    
    I have successflly used a VAX/VMS system running DECnet/OSI as a X.25
    gateway for Alpha VMS systems. So there is some sort of precedent for
    what you are trying to do.
    
    
515.2NO nettrace.exe on this system...OSLAGE::AGE_PAage Ronning, Oslo, Norway, (DTN 872-8464)Mon May 05 1997 19:3412
>>    In the DECnet/OSI environment CTF is the trace utility. CTF is invoked
>>    by the command TRACE.

The problem is that TRACE tries to invoke sys$system:nettrace.exe, BUT on this
Alpha system there is NO nettrace.exe(only a nettrace_tv.exe). I tried to rename
this image, but then it seemed like the sys$library files where incompatible
with the image.
I don't have access to the system right now, but I could post the output later
if wanted. 
What is the easiest way to get trace up and working (Could I copy some files)?

Why do we have 7 NW devices owned by "X25$APPLD" even seconds after a restart?

As Arthur notes, NETTRACE is *not* what you should expect TRACE to invoke! I
have hit this problem once, recently on a VAX. Something, somewhere had
installed the old PSI Phase IV TRACE utility (NETTRACE); in my case it was
probably an installation of an X25router kit or somesuch. How this might happen
on an Alpha, I have no idea. Try a re-install of DECnet-Plus followed by a
reboot, if that does not sort out TRACE, send me mail and I'll send you the
TRACE.CLD source as a workaround.

    There is an NW device owned by X25$APPLD for EACH X.25 or X.29
    application that has been defined (by  e.g. $ mcr ncl create x25 access
    application ... ).
    
    X25$APPLD does NOT own NW devices for x25 applications that are not
    created dynamically in response to incoming calls. (X29 login is the
    single exception.)
    
    
515.7NSP flow control policy again?UTRTSC::VROOIJLearning to fly...Tue May 13 1997 20:3610
    For the logins problems have you checked 'NSP FLOW CONTROL POLICY'
    The last few weeks I have had several customers complaining about
    X25GAP problems from alpha with X25gateway/DECnis as connector node.
    As soon as the flow control policy is changed from segment to NO flow
    control the problems where gone. I haven't had time to build a test
    environment to reproduce the problem but I believe on Alpha there is
    still a flow control problem with 'segment flowe control'

515.9No IPMT yet.UTRTSC::VROOIJLearning to fly...Thu May 15 1997 21:168
    Arthur,
    
    I haven't logged an IPMT yet. All I know at this moment is that
    changing the flow control solves the customer problem. If time permits
    I want to setup an test-environment to see if it can be reproduced. 
    I'll log an IPMT then.
