A table that lists the cache buffer pools
configured on a managed system.
1)To provide a noticeable performance boost,
Cache Pool can be used. A Cache Pool is effectively
a lookaside list of free buffers that can be
accessed quickly. Cache Pool is tied to Buffer Pool.
2)Cache pools can optionally have a threshold value
on the number of cache buffers used in a pool. This
can provide flow control management by having a
implementation specific approach such as invoking a
vector when pool cache rises above the optional
threshold set for it on creation.
