When you first install Adaptive Server, it has a single data cache that is used by all Adaptive Server processes and objects for data, index, and log pages. The default size is 8MB.
The following pages describe the way this single data cache is used. “Configuring the data cache to improve performance” describes how to improve performance by dividing the data cache into named caches and how to bind particular objects to these named caches.
Most of the concepts on aging, buffer washing, and caching strategies apply to both the user-defined data caches and the default data cache.
