Likewise, I always believed that if you had to use DOS, then you have a
better understanding of how Windows operates, because it has to go through
DOS to reach the hardware.
Assembly language is useful too, if you like headaches.
Another reason to learn the command line is that GUI tools very rarely
include all the options, you usually have more flexibility when using
commands than when using the GUI. The GUI is useful for doing simple,
standardized tasks like creating one or two user accounts at a time.
e.g. when you install 8.1.7, you can't tell Oracle to use local
administration of the tablespaces. You have to go in after the
installation, delete all those tablespaces, and re-create them manually...
using another GUI tool (DBA Studio)! When both tools should be able to do
the same work.
Also, let's say Oracle decides they don't like a tool, and they drop it
altogether, and come up with a different GUI. What will you do then? You
have to learn a "new" application, and if you don't understand what is
happening underneath, you won't be able to adapt as easily.
The GUI tools are not consistent either, some use the .ora file extension
for datafiles, others use .dbf. It seems to change from version to version.
I am also not clear on how the tools user small case vs. capital letters
when creating datafiles on case-sensitive OSes. You have to be careful with
these tools.

I'm not morally opposed to GUI tools... and using them doesn't make
you a
bad DBA. But I really think that you (generic you) need to
understand what
the tool is doing, so that if you end up somewhere that doesn't have
and
won't buy the tool, you can still do your job.
