Oracle® Enterprise Manager Grid Control Installation and Configuration Guide
10g Release 5 (10.2.0.5.0)
Part Number E10953-15
18 Configuring Enterprise Manager for Active and Passive Environments
18.1 Using Virtual Host Names for Active and Passive High Availability Environments in Enterprise Manager Database Control
Set Up the Alias for the Virtual Host Name and Virtual IP Address
You can set up the alias for the virtual host name and virtual IP address by either allowing the clusterware to set it up automatically or
by setting it up manually before installation and startup of Oracle services. The virtual host name must be static and resolvable consistently
on the network. All nodes participating in the setup must resolve the virtual IP address to the same host name. Standard TCP tools similar
to nslookup and traceroute commands can be used to verify the set up.
My question is, for the paragraph above, there seems to be missing details. It is assumed that the reader already know how to do it?
Can you help me find the missing detail docs for this?
