Oracle Masters Program
The Oracle Masters programs are
especially useful in that they take the guesswork out of which
classes you should take. Consult with Oracle training about
schedules and classes. For large Oracle installations with large
numbers of developers and administrators, Oracle, and vendors, will provide on-site classes that may significantly reduce
your training costs. Another good program is the Oracle Certified
Professional (OCP) DBA certification program. For a fee, you can go
to any Sylvan Learning Center and take a set of examinations that
will determine if you have the prerequisite knowledge to be a DBA on
Oracle. However, if you donít have at least two years of experience
in Oracle and some training, donít waste your money. I have taken
these exams; they arenít a piece of cake by any means.
If you have training on-site, donít allow outside interruptions to
intrude upon the class. These can be disruptive and are rude to the
instructor. Besides, it wastes your training money.
Would you allow a first-time driver to just jump into the car and
drive off? It is amazing how many sites turn new and complex systems
over to personnel with perhaps a good background in databases but no
experience whatsoever in Oracle. Yes, there are generic issues, but
there are enough details specific to Oracle alone that training is
highly recommended. If it costs $20,000 to fully train a DBA, isnít
it worth it? How much money would it cost if the system were down
for several days while an inexperienced DBA pored through the
manuals and tried to communicate intelligently with the Oracle help
line? What if a critical application were destroyed because of
something the DBA did or didnít do? At one site, an experienced DBA,
new to the Oracle database system, didnít follow the normal database
datafile-naming convention recommended by Oracle. Even though
backups were taken, they didnít get the one SYSTEM datafile that was
named incorrectly. As a result, when an application required
recovery due to data corruption, the system couldnít be restored.
This resulted in the users abandoning the application and investing
hundreds of hours reinventing it on Mac systems.
