overstated. If this occurs, the percentage of data cache misses reported by Cache Hit
Pct is understated.
Type: Result
The name of a data cache. Particular database tables and indexes may be bound to a
specific data cache, or all objects in a database may be bound to the same data cache.
No object may be bound to more than one cache.
