Troubleshooting
The Compaq FTAM responder returns diagnostic messages to your application as
specified by the ISO 8571 standard. In many cases, more information is returned than is
required by the standard. Appendix A, “Compaq FTAM Responder Diagnostic
Messages,” provides cause, effect, and recovery information about all diagnostic
messages returned by the responder.
specified by the ISO 8571 standard. In many cases, more information is returned than is
required by the standard. Appendix A, “Compaq FTAM Responder Diagnostic
Messages,” provides cause, effect, and recovery information about all diagnostic
messages returned by the responder.
Some responder diagnostic messages also contain text of up to 256 characters in the
Further Details field, providing additional information on the nature of the problem. For
example, if you attempt to create a file and receive diagnostic message 3006 (file cannot
be created), the Further Details text provides the file-system error number returned by
Guardian when the file creation attempt failed. A Compaq problem solver or someone
else with access to the Compaq system can look up this number in the Guardian
Procedure Errors and Messages Manual to obtain information on what occurred and
how to correct the problem.

As another example, if you attempt to open a file and receive diagnostic message 5036
(contents type inconsistent), the Further Details text “illegal MSL value” indicates that
you attempted to open a file with a maximum-string-length parameter value outside the
range supported by the Compaq FTAM responder, as described under “Mapping
Between FTAM Contents Types and Compaq File Structures” in Section 4.

Troubleshooting
To detect and eliminate problems in your remote application, you need to use whatever
debugging tools are available on the remote system. However, there are also
troubleshooting tools available on the Compaq system where the responder runs that can
provide additional information about a problem. If you encounter interoperability
problems or other problems that appear to originate on the Compaq system, you should
work with a Compaq problem solver who has access to these tools.

The Compaq troubleshooting tools include the following:
•
The Event Management Service (EMS) log
•
Subystem Control Facility (SCF) interactive interface
•
The PTrace utility
The Event Management Service (EMS) on Compaq systems enables the Compaq
problem solver to monitor problems and other significant events that occur during the
operation of Compaq FTAM and other Compaq software. The FTAM responder and the
APLMGR process that manages it generate event messages when they detect
significant events, as do the processes in the underlying OSI/AS, OSI/TS, X25AM, and
TLAM (or PAM for G06 and above releases) and TCP/IP subsystems. Event messages
are logged to the console or displayed on a terminal as operator messages, which are
described in the Operator Messages Manual.
