In this example, two replicas of the RAC database must be configured; one at Site A and the other
at Site B. Create the database at the nodes in the Site A site and replicate the configuration and
data to the nodes in the Site B site. Install the RAC database software on the local file system at
each node. The database uses two CFS file systems for database files; one for the database data
and the other for flash recovery area. Configure the RAC database using the SGeRAC toolkit at
each site. The disk group names and file systems mount point paths must be the same for both the
site databases. However, the disk groups and mount points are packaged using different packages
at each site CFS sub-cluster.
Table 17 lists the packages and other resources at each site.
