A data warehouse team is reporting poor performance on their batch reports. The database
runs on a Solaris host connected to a DMX-4 array with Fibre Channel drives sized to
support a sequential read workload. Which metrics in Performance Manager would be
useful in diagnosing the performance issue?

A.
Average sampled read time, KBytes read per second, I/O per second, Read hit %

B.
KBytes read per second, Prefetched tracks per second, Read %, Write %

C.
Read hit %, Tracks not used per second, Average sampled read time, I/O per second

D.
I/O per second, KBytes read per second, prefetched tracks per second, Tracks not used
per second
