<p>Use the QzhtAddTCMHostDesc API to add new host descriptions to the configuration
of triggered cache manager servers. New host descriptions are referenced subsequently,
by name, from certain types of data source, cache target, and acknowledgment
target descriptions associated with the same server. New host descriptions
are utilized by all descriptions referencing them the next time the servers
are started. 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>
