<h5 id="rzahjerr-appccontref">APPC controller recovery summary</h5>
<p>The action the system takes when advanced program-to-program communications
(APPC) controller descriptions go into recovery depends on the setting of
many parameters. The following tables can help you understand and select the
appropriate configuration parameters to best optimize system behavior when
APPC controllers representing personal computer clients go into error recovery.</p>
