The figure shows two nodes, node 1 and node 2, for running OracleAS Infrastructure. These nodes use the virtual address "vhost.mydomain.com" and the virtual IP 220.127.116.11. Node 1 is the primary and active host; node 2 is the secondary host. The virtual address and virtual IP are associated with node 1 (the active host). On failover, they will be associated with node 2.
Oracle Fail Safe is installed on the local storages of node 1 and node 2, in the
C:\Oracle\OFS directory. The local storages also contain the inventory directory (
Node 1 and node 2 are associated with a common shared storage. Node 1 has access to the disk during normal runtime. If node 1 fails, a failover event occurs and node 2 gets access to the disk. OracleAS Infrastructure (including the Oracle Identity Management and OracleAS Metadata Repository) is installed on this shared storage. The Oracle home directory for OracleAS Infrastructure is
F:\Oracle\ias, and the data files for the OracleAS Metadata Repository database are stored in
In addition to the two nodes for the OracleAS Infrastructure, the figure shows additional nodes for running Oracle Application Server middle tiers.
