Incident/event relationship for multiple events
In addition to events and incidents, there is the concept of
problems
. Problems can be viewed as the source or
root cause of incidents. They currently manifest themselves as errors in Oracle software. Problems are outside the
scope of this discussion, as they can really be anything that causes an interruption or degradation of service. Rodents
running loose under your server room floor, for example, can be a problem if they chew through wires and cause
downtime.
■
one of the challenges of a dBa's job is to constantly deal with problems that cannot all be foreseen. indeed,
the presence of a heretofore new problem is part of the “spice” that makes dBa work enjoyable and rewarding. Yet at the
same time, we strive for the routine. such is the inherent tension in our line of work.
Note
Effectively managing incidents helps us to achieve better operational efficiency, helping us take control of the
overall health of our system. Using a centralized incident management console allows us to view, manage, diagnose,
and resolve incidents from a single location. A complete discussion of incident management is handled in Chapter 12.
The diagram in Figure

shows the workflow of events and incidents using EM12c.
