<p>The QzhtChgTCMRuleSet API changes rule sets associated with triggered cache
|
|
manager servers. Changes made to rule sets are utilized by all trigger handler
|
|
descriptions that are referencing them the next time that the servers are
|
|
started.</p>
|
|
<div class="note"><span class="notetitle">Note:</span> Triggers are sent to trigger handlers which process them according to
|
|
publishing rules. Custom publishing rules are provided for the trigger handler
|
|
through a rule set. If extensions of files identified in triggers match one
|
|
of the extensions listed in a custom publishing rule, they are processed according
|
|
to that publishing rule. If extensions do not match any of the custom publishing
|
|
rules, the file is processed according to the default publishing rule.</div>
|
|
<p>The API is a callable service implemented as an ILE entry point within
|
|
QZHTINCONF *SRVPGM in QTCM *LIB.</p>
|

<p>The QTCM/H(QZHTINCONF) header file includes ILE C prototypes for this API.</p>
