<h2 id="rzahjtrb">Troubleshooting APPN and HPR</h2>
|
|
<p>If an error log indicates that the route to the remote location cannot
|
|
be found, the <a href="rzahjrzahjstrpathr.htm#rzahjstrpathr">Start Pass-Through (STRPASTHR)</a> command
|
|
attempts to make the connection again. The STRPASTHR command has built-in
|
|
detailed diagnostic capabilities that exceed those provided by other interfaces
|
|
that use APPN, or HPR networks. These diagnostic capabilities include problem
|
|
analysis, functions for problem and error logging (including directory services
|
|
search information), and route calculation information. However, the system
|
|
records all session initiation errors in the error log.</p>
|
|
<p>When a STRPASTHR command fails to contact a remote location in an APPN
|
|
network, a record is written to the problem log. The record is written if
|
|
there is an associated problem record for analyzing the data. The Work with
|
|
Problems (WRKPRB) and Analyze Problem (ANZPRB) commands enable you to examine
|
|
and interpret the problem log to help you isolate the problem.</p>
|
|
<p>The <a href="rzahjprbcomdspappninsts.htm#rzahjprb-comdspappninsts">Display APPN Information (DSPAPPNINF)</a> command can help you understand the topology of your network. It displays
|
|
the names of all known remote control points and their locations, intermediate
|
|
sessions, and link status information. The <a href="rzahjprbcomwrkappnref.htm#rzahjprb-comwrkappnref">Work with APPN Status (WRKAPPNSTS)</a> command provides session-related information
|
|
for advanced program-to-program communications (APPC) controller descriptions.
|
|
These controller descriptions represent connections to adjacent systems by
|
|
using Advanced Peer-to-Peer Networking® (APPN), or
|
|
high-performance routing (HPR).</p>
|
|
<p>If no problem record exists for a particular type of error, the system
|
|
does not record a message in the problem log. However, the system records
|
|
all errors in the error log. The error log entry may help your service personnel
|
|
isolate the problem.</p>
|
|
<p>If you have a communication problem specifically related to APPN and HPR
|
|
running over your system, reviewing the following topics might also help in
|
|
troubleshooting:</p>
