Active Cluster uses a single, centralized cache to reduce the impact on back-end database systems. The first node to access a data source caches the data. Subsequent calls from other nodes access the cached data.

All servers in the cluster know the state and location of all database caches, regardless of which server does the refresh, because this information is stored in the database. TDV Manager provides a cluster status table that displays which server performed the refresh.

A file-system cache cannot be shared by cluster servers because status is stored on the local file system. File-system caches are replicated on every node in the cluster.
