Using Serviceguard Extension for RAC, 5th Edition, June 2007

Introduction to Serviceguard Extension for RAC
Overview of SGeRAC and Cluster File System (CFS)/Cluster Volume Manager (CVM)
Chapter 122
CFS provides SGeRAC with additional options, such as improved
manageability. When planning a RAC cluster, application software could
be installed once and be visible by all cluster nodes. A central location is
available to store runtime logs, for example, RAC alert logs.
Oracle RAC data files can be created on a CFS, allowing the database
administrator or Oracle software to create additional data files without
the need of root system administrator privileges. The archive area can
now be on a CFS. Oracle instances on any cluster node can access the
archive area when database recovery requires the archive logs.
