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

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

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

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