Troubleshooting the APPC Subsystem
Submitting an SR
• Document your interim, or “workaround,” solution. The cause of the
problem can sometimes be found by comparing the circumstances in
which it occurs with the circumstances in which it does not occur.
• Save copies of any SNA link or SNA service trace files that were
active when the problem occurred.
• If the problem involves NMMGR, give a copy of NMMGRF.PUB.SYS to
your HP representative.
• If a system failure has occurred, take a full memory dump.
• If a fatal link error has occurred, an error message will appear on
the operator’s console. Be sure to include this error message in the
SR exactly as it appears on the operator's console.
• Save copies of all active or in-use trace files for analysis by your HP
representative.
• Save copies of all active or in-use log files for analysis by your HP
representative.
• Record all intrinsic result codes and messages that appear at the
HP 3000 console or at the terminal from which the APPCCONTROL
START command was issued.
• Always obtain a copy of the host generation for ACF/VTAM and
ACF/NCP and for the application subsystems that the APPC
subsystem uses. If the HP 3000 is communicating with an AS/400,
obtain a copy of the configuration on the AS/400.
Note any differences between the actual system generation and your
expectations. Keep this information for your HP representative.
• Give a copy of NMCONFIG.PUB.SYS to your HP representative.
WARNING The normal checks and limitations that apply to the standard
users are bypassed in privileged mode. It is possible for a
privileged mode program to destroy file integrity, including the
MPE operating system software itself. Hewlett-Packard will
investigate and attempt to resolve problems resulting from the
use of privileged mode code. This service, which is not provided
under the standard Service Contract, is available on a time and
materials billing basis. Hewlett-Packard will not support,
correct, or attend to any modification of the MPE operating
system software.
