AHL trace on V24

[murraya]

Hi guy's, I was hopeing someone can assist with a trace for AHL link. I normally just use tcpdump and filter the ip @ of the front office computer but this time I need to trace the link and its on V24.
has anyone got a trace command that will show messages on the link. the site is remote so I can't put a physcial monitor on the link.
I couldn't see a tuner or actdbg command that would help but I'm sure there must be one that someone knows

thanks in advance.

The easiest way is by launching 'traced' command. It might be neccessary to add the argument '-d' (debug) to the linf process to get some output, depending on oxe version. The argument is defined in hotel computer link parameters.

Thanks Bjin, I had tried the traced command but could not really see anything. I'm not sure what you mean about adding the -d to the linf process. I did get the site working the other day by restarting that process as I know that it is the AHL process. When I look in computer link parameters I can't see where I would start the debug option.

Its right there, think its called "parameters" and is normally left empty...have no access to an oxe to verify the param name at the mo...

I've just checked it and it's called 'LINF parameter', on the same page you pasted from above...
Just enter '-d' and traced should provide verbose output. I've used it many times and it works great.

PS - There's no good reason to omit the -d flag as it doesn't affect the performance in any way. One exception however is when using master/slave config in AHLTCP mode and when you have to set '-ahltcp' in order for the master to send ack's to external computer before receiving the ack from it's slave, but thats another topic...

OK, I see the issue. This paramater is only available if the connection is IP not V24.
that is a useful tip and may be better than mt tcpdump for those traces but will not work for V24.

Oh crap :0/ This flag only need be added to the linf process when it starts...
However... I'm not sure if v24_config is involved in starting linf when using serial port..? This might be good to investigate.

as a thought maybe i'll try dsh3_init -R LINF -d next time i need it and see if that helps
maybe someone else might have an idea. Elliot somtetimes comes up with gems for these types of questions i sometimes think he he knows things that that only the coders know

thanks for your time and effort Bjin
