G&R

Host Links Trace

If you experience any kind of problem when using a Host Links application, the

application trace file and/or the line handler trace file will provide useful

documentation of the problem.

Trace activation

The Host Links products automatically create sub-directories in the debug

directory when debug is activated: at product level using the -d/jointfilesconvert/469813/bg parameter,

or at line level using the -d_ or -s_ parameters to the line module.

Windows

server

gspool -id gs1 –d/jointfilesconvert/469813/bg –ps \\SERVER\LEXMARK

-li dsa -da tptst -d_ on

UNIX

Linux

gspool -id gs1 -d/jointfilesconvert/469813/bg-pc lp -li dsa

-da tptst -d_ on

Most G&R products include a facility for setting product or line parameters

dynamically. It is therefore generally possible to turn on debug or trace without

modifying the command line or configuration of a production system.

Trace types

All Host Links products accept a parameter –d/jointfilesconvert/469813/bg, which starts an application

level trace of internal events. This is useful when investigating malfunctions or

looking closely at product behaviour.

All Gline line handlers accept a parameter -d_ to turn on a data trace. It

records data and enclosure level being exchanged with the line handler. It is

useful when documenting product malfunction e.g. an emulation error, because

it records exactly what the host sends and what the G&R application replies. It

can be used to simulate a customer situation, reproduce a problem and to verify

that a correction fixes the documented problem.
