8.2 Pre-Installation Steps for OracleAS Cold Failover Cluster
Before installing Oracle Application Server in an OracleAS Cold Failover Cluster,
perform these procedures:
Section 8.2.1, "Map the Virtual Hostname and Virtual IP Address"
■
Section 8.2.2, "Set Up a File System That Can Be Mounted from Both Nodes"
■
Section 8.2.3, "Review Recommendations for Automatic Storage Management
■
(ASM)"
Section 8.2.4, "Check That Clusterware Is Running (Automated Failovers only)"
■
Section 8.2.5, "Modify listener.ora file for Existing Database"

8.2.1 Map the Virtual Hostname and Virtual IP Address

Each node in an OracleAS Cold Failover Cluster configuration is associated with its
own physical IP address. In addition, the active node in the cluster is associated with a
virtual hostname and virtual IP address. This allows clients to access the OracleAS
Cold Failover Cluster using the virtual hostname.
Virtual hostnames and virtual IP addresses are any valid hostname and IP address in
the context of the subnet containing the hardware cluster.
The following example configures a virtual hostname called vhost.mydomain.com,
with a virtual IP of 138.1.12.191:
Register the virtual hostname and IP address with DNS for the network.
1.
For example, register the vhost.mydomain.com/138.1.12.191 pair with
DNS.

8.6.
In addition to the requirements listed in this chapter, ensure
Note:
that you meet the requirements described in
"Requirements for High Availability
Note:
Map the virtual hostname and virtual IP address only to the
■
active node. Do not map the virtual hostname and IP address to
both active and secondary nodes at the same time. When you
failover, only then map the virtual hostname and IP address to
the secondary node, which is now the active node.
Before attempting to complete this procedure, ask the system or
■
network administrator to review all the steps required. The
procedure will reconfigure the network settings on the cluster
nodes and may vary with differing network implementations.
