In this example, two replicas of the RAC database must be configured; one at Site A and the other
at Site B.The database must be created at the nodes in the Site A site and the configuration and
data must be replicated to the nodes in the Site B. The RAC database software must be installed
on the local file system at every node. The database uses two CFS file systems for database files;
one for the database data and the other for flash recovery area. The RAC database must be
configured using the SGeRAC toolkit at every 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 every site CFS sub-cluster.
Table 28 lists the packages and other resources at every site.
