Migration to Oracle
Once the installation of the new
Oracle software is complete, what do we, as DBAs and application
developers, do? We migrate. Of course, we should take the proper
steps to ensure that we migrate like graceful geese flying across a
sunset rather than lemmings dashing forward over a cliff (see Figure
1.20). Naturally, as DBAs, we prefer the graceful flight across the
sunset.
Planning Migration
How do we accomplish this graceful migration? Planning. Planning is
the only way to minimize points of possible failure in your
migration path from Oracle 6.x, Oracle 7.x, or Oracle8/8i to
Oracle. In this section, I will attempt to provide a logical
framework for planning your migration and hopefully shine a light on
the pitfalls that you should avoid along the way
Have you known someone who immediately takes new items (VCRs,
computers, TVs) right out of the box, plugs them in, and never reads
instructions? Later, they fret because the blankity-blank item won’t
do what they want (or, more likely, they don’t know how to make it
do what they want). They didn’t prepare to migrate to their new
appliance. This preparation should have involved reviewing the
installation and operation manuals, performing controlled tests of
new features, and then finally bringing the new appliance into full
use (see
Figure 1.21).
