<p>Use the QzhtChgTCMTriggerHandlerDesc API to change trigger handler descriptions
associated with triggered cache manager servers. Changes made to trigger handler
descriptions are utilized by triggered cache manager servers after they are
restarted. The API is a callable service implemented as an ILE entry point
within the QZHTINCONF *SRVPGM in the QTCM *LIB. </p>
<p>The QTCM/H(QZHTINCONF) header file includes ILE C prototypes for this API.</p>
