In this example, two replicas of the RAC database must be configured; one at San Francisco and
the other at San Jose. Create the database at the nodes in the San Francisco site and replicate the
configuration and data to the nodes in the San Jose 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 18 lists the packages and other resources at each site.
