10.2.4 If You Want to Use OracleAS Cold Failover Cluster on the Production Site
On the production site of a OracleAS Disaster Recovery system, you can set up the
OracleAS Infrastructure to run in a OracleAS Cold Failover Cluster configuration. In
this case, you have two nodes in a hardware cluster, and you install the OracleAS
Infrastructure on a shared disk. See
Chapter 8, "Installing in High Availability
Environments: OracleAS Cold Failover Cluster" for details.
Figure 10–4 Infrastructure in an OracleAS Cold Failover Cluster Configuration
To set up OracleAS Cold Failover Cluster in this environment, use the virtual IP
address (instead of the physical IP address) for asinfra.asha on the production site. The
following example assumes 138.1.2.120 is the virtual IP address.
asmid1.asha IN A 138.1.2.333
asmid2.asha IN A 138.1.2.444
asinfra.asha IN A 138.1.2.120 this is a virtual IP address
remote_infra.asha IN A 213.2.2.110
On the standby site, you still use the physical IP address for asinfra.asha, but the
remote_infra.asha uses the virtual IP address.
asmid1.asha IN A 213.2.2.330
asmid2.asha IN A 213.2.2.331
asinfra.asha IN A 213.2.2.110 physical IP address
remote_infra.asha IN A 138.1.2.120 virtual IP address
10.3 Installing Oracle Application Server in an OracleAS Disaster
Recovery Environment
Install Oracle Application Server as follows:
Production Site
prodinfra = 138.1.2.111 prodinfra2 = 138.1.2.112
Virtual hostname: asinfra
Virtual IP address: 138.1.2.120
