Oracle Training Learning Objectives|
In this 3-half day performance troubleshooting course, participants will learn how
to measure and diagnose performance issues exhibited by a system; as well as
learning triage techniques for isolating the proximal and root cause for a multitude
of performance issues.
This course material is interdisciplinary; the material covers topics in the realm of
system administration, database administration, storage administration and
network administration. It is dominantly targeted to these job titles and their
Participants will learn the optimal approach to diagnosing a performance problem,
and how to arrive at an optimal solution to address the diagnosis.
