In a clustered environment, you can configure Oracle BI Servers to access a shared cache called the global cache. The global cache resides on a shared file system storage device and stores purging events, seeding events (often generated by Agents), and result sets associated with seeding events.
Each Oracle BI Server still maintains its own local query cache for regular queries.
to open Enterprise Manager.
The cache is enabled by default. To disable the cache, clear the checkbox.
In Global cache path, enter the path to the physical location for storing purging and seeding cache entries shared across the cluster. The location that you enter must reside on a shared file system that is accessible by all nodes in the cluster.
In Global cache size, specify the maximum size of the global cache (for example, 700 MB). When this limit has been reached, potential new entries are not cached.
As a courtesy, ensure that the restart will not affect other users. When the server is rebooted, the new caching requirements are applied.
