Oracle Fusion Middleware consists of many components that can be deployed in distributed topologies. The underlying paradigm used to enable high availability for Oracle Fusion Middleware is clustering, which unites various Oracle Fusion Middleware components in certain permutations to offer scalable and unified functionality, and redundancy should any of the individual components fail. For more information, see Section 2.5, "Setting Up a High Availability Environment".
To specify a shared cache directory for high availability (HA):
Log in to Oracle Enterprise Manager.
Navigate to the Reports Application Home page (see Section 7.3, "Viewing the Component Topology").
From the Reports menu, select Administration > Advanced Configuration.
The Reports Application Advanced Configuration page displays.
In the High Availability Parameters section, in the Cluster Cache Directory field, enter the path to the shared cache directory for HA, then click Apply.
To see the changes, reload the WLS node.
