The site host table is generated from the hlq.HOSTS.LOCAL data set. This data set contains descriptions of local host entries in the HOSTS format. HOSTS.LOCAL can contain only IPv4 addresses. A sample HOSTS.LOCAL data set is created during installation. This information describes how to update the sample hlq.HOSTS.LOCAL data set and use it to generate the two data sets, hlq.HOSTS.SITEINFO and hlq.HOSTS.ADDRINFO, which function as your site table.
