The IP-to-Hostname Aliasing function accesses the Domain Name System (DNS) server to define hostname aliases for client and server IP addresses. Note that there are two separate sets of IP addresses - one for clients, and one for servers.
Select Administration Console > IP-to-Hostname Aliasing.
Mark the Generate Hostname
Aliases for Client and Server IPs (when available) checkbox to
enable hostname aliasing.
A second checkbox displays when the first is marked: Update
existing Hostname Aliases if rediscovered
Mark the "Update existing..." checkbox to update a previously defined alias that does not match the current DNS hostname (usually indicating that the hostname for that IP address has changed). You may not want to do this if you have assigned some aliases manually. For example, assume that the DNS hostname for a given IP address is dbserver204.guardium.com, but that server is commonly known as the QA Sybase Server. If QA Sybase Server has been defined manually as an alias for that IP address, and the "Update" checkbox is marked, that alias will be overwritten by the DNS hostname.
Click the Apply button to save the IP-to-Hostname Aliasing configuration.
Do one of the following:
Click the Run Once Now button to generate the aliases immediately.
Click the Define Schedule button to define a schedule for running this task. For instructions on how to use the general-purpose task scheduler, see Scheduling.
To view the aliases defined, see View the Aliases Defined, in the Common Tools book.
