About the location of ORACLE_HOME
Before installing Oracle binaries (ORACLE_HOME) locally on each system or on a cluster file system on shared storage as described in Installing Oracle 10g RAC, consider these points:
-
Local installations provide a comfort level using traditional installation methods and the possibility of improved protection against a single point of failure.
-
CFS installations provide a single Oracle installation to manage, regardless of number of nodes. This scenario offers a necessary reduction in storage requirements and easy addition of nodes.
Select the location based on your high availability requirements. Symantec and Oracle generally recommend using local installations.
