Here, I've created a host connection for one path of my server with WWPN 2100001b3204b7ba, which connects to the DS8000's I/O port I0001 and maps volume group v35 (myvolgrp) to this host connect.

By setting this property, all references to the airlinesDB database in the JDBC connection URLs can just refer to 'airlinesDB' instead of the full file system path.

The Informix communication libraries will trace all the SQLI messages into a series of files, with one file per connection, and with the prefix path provided in the SQLIDEBUG variable.
