Oracle Database Oracle Clusterware Installation Guide for HP-UX

Preparing to Install Oracle Clusterware with OUI
❏ Determine your cluster name, public node names, private node names, and
virtual node names for each node in the cluster
If you install the clusterware during installation, and are not using third-party
vendor clusterware, then you are asked to provide a public node name and a
private node name for each node. If you use vendor clusterware, then use your
vendor documentation to complete setup of your public and private domain
addresses.

When you enter the public node name, use the primary host name of each node. In
other words, use the name displayed by the hostname command. This node
name can be either the permanent or the virtual host name.
In addition, ensure that the following are true:
– Determine a cluster name with the following characteristics:
* It must be globally unique throughout your host domain.
* It must be at least one character long and less than 15 characters long.
* It must consist of the same character set used for host names: underscores
(_), hyphens (-), and single-byte alphanumeric characters (a to z, A to Z,
and 0 to 9). If you use vendor clusterware, then Oracle recommends that
you use the vendor cluster name.
– Determine a private node name or private IP address for each node. The
private IP address is an address that is accessible only by the other nodes in
this cluster. Oracle Database uses private IP addresses for internode, or
instance-to-instance Cache Fusion traffic. Oracle recommends that you
provide a name in the format public_hostname-priv. For example:
myclstr2-priv.
– Determine a virtual host name for each node. A virtual host name is a public
node name that is used to reroute client requests sent to the node if the node is
down. Oracle Database uses VIPs for client-to-database connections, so the
VIP address must be publicly accessible. Oracle recommends that you provide
a name in the format public_hostname-vip. For example: myclstr2-vip.
Note: The following is a list of additional information about node IP
addresses:
■ For the local node only, OUI automatically fills in public, private,
and VIP fields. If your system uses vendor clusterware, then OUI
may fill additional fields.
■ Host names, private names, and virtual host names are not
domain-qualified. If you provide a domain in the address field
during installation, then OUI removes the domain from the
address.
■ Private IP addresses should not be accessible as public interfaces.
Using public interfaces for Cache Fusion can cause performance
problems.
