This chapter describes some elements of cluster architecture in greater detail. Many topics describe cluster-specific aspects of features available in both the clustered and nonclustered Adaptive Server.
Many subsystems of nonclustered Adaptive Server work in a shared-disk cluster environment; others have been developed specifically for the Cluster Edition. These subsystems are:
Lock manager
Buffer manager
Cluster interprocess communication (CIPC)
Recovery (start time and failover handling)
