How I became an Oracle 10g DBA
Article by
Rampant Author Brian Carr
In this article
I want to explain the steps I took
and a general timeframe to possibly
inspire other technical
professionals to become Oracle DBAs.
I for one find it very worthwhile
and I enjoy going to work everyday.
I started my technical career while
still in college as a technical
support rep. I then moved over to
programming for a few years. I
didn't always make the best
programmer because I ALWAYS put
function before form. I became
interested in the idea of being a
DBA as I worked around some of them.
I liked the level at which they got
involved in projects. They didn't
care if the user wanted a green icon
on the screen which they could mouse
over for info. DBAs care about
entities, relationships and
elements. A good DBA can ask a
couple dozen business questions in a
relatively short time and have the
relationships and entities necessary
for creating a solid Oracle
database. The programmer can usually
provide the elements needed. I like
being an Oracle DBA because of this.
So after being a programmer for a
few years I moved on to being an
Information Analyst. My primary role
here was creating solid data models
and assisting user's with OLAP
reporting.
Data Modeling
I actually took some formal Oracle
data modeling courses during my
transition from programmer to
Information Analyst. This helped
ground me in some solid data
modeling principles.
Expressing Interest
While being an Information Analyst I
expressed to my boss that I was very
interested in becoming an Oracle
DBA. My boss was supportive and
believed in building her employees
so she allowed me to explore a bit
into the land of DBA.
Certification
After building my first Oracle 8
database to support the Information
Warehouse I migrated our first
system into the Oracle database.
After being a DBA for about a year I
decided set a goal to be certified
as an Oracle Certified Professional
(OCP). Back when I earned my OCP
certification it was 5 tests in
total. I failed at my first test
because I underestimated the types
of questions they would ask. I
passed my that test on the second
attempt and everyone there after on
the first attempt. What worked best
for me and for another person I know
was buying the Computer Based
Training (CBT) disks directly from
Oracle. Oracle is not paying me to
say this. They just work VERY well.
To sum it up I passed the first test
by reading the Oracle Press book and
the last 4 tests via the Oracle CBT
disks. They aren't cheap, but I
found it very worthwhile. I've got
my investment back many times over
by being promoted to a Senior
Database Administrator. Since then
I've even been promoted to a team
lead.
Helping the
community
One of the more interesting findings
while being an Oracle 10g DBA was
when I found & reported bug to
Oracle in the Oracle Application
Server product. At the time I only
used Application Server to serve up
reports.
