Home -> Community -> Mailing Lists -> Oracle-L -> RE: Jr.DBA, Mid level DBA, Sr.DBA
I agree, the Jr. DBA must focus on learning.
Mid DBA...is still learning. Many Mid still view tuning/troubleshooting as
an art (with a little magic thrown in)
Sr. DBA...is still learning. Realizes that database management is a science,
requiring research, expirementation and a very healthy dose of skepticism.
The best Sr. DBAs that I know are the first ones to say 'I don't know'. That is the only true path to learning. No one can know everything. Often times the Jr. DBA will be a great source of knowledge since they don't know what NOT to ask.
Reaction to reading Books/Documentation
Junior - I did not know that
Mid - I know that
Senior - Perhaps...let's prove it
When a developer/user asks for a change to the database
Junior - I'll look it up and change it
Mid - I have a script to do that, I'll let you know when I am done
Senior - Why are you needing this change? Did you realize that x will cause
y? Let's figure out the best way to accomplish the result.
When faced with an undocumented condition/unknown error
Junior - Log a TAR, get frustrated with 'We need a trace file. We need more
information. <We have no clue...>'. Calls more senior help.
Mid - Remembers a passage in a book, tries out the command. Fixes the
symptom.
Senior - Knows that x can cause y, if z is present. Tracks condition from
symptom through to actual problem.
Attends sessions at IOUG
Junior - Assumes that all speakers know exactly what they are talking about
and all vendor tools work as advertised.
Mid - Listens to and believes Tim, Cary, Craig, Rich, Rachel, Gaja and all
other High Holy Oracle Gurus preach
Senior - Listens to, questions and tests (on non production systems) what
Tim, Cary, Craig, Rich, Rachel, Gaja and all other High Holy Oracle Gurus
preach
Knowledge level
Junior - Has no clue what they know and don't know
Mid - Knows what they know
Senior - Knows what they don't know
Every Senior DBA is a mix of Jr. and Mid. They may know a great deal about one subsystem of Oracle, but lack knowledge in another area.

Junior DBA's job is a learning.
Mid DBA's job is a science.
Sr. DBA's job is the Art.
Srs feel database, users, developers and everything else.
They feel what, where, how, when and why should by done.
Their intuition is of high degree.
... and everybody is sure - the Sr DBA knows everything. (so one of the
priority of Sr DBA is to make this impression)
