Like the Database Configuration Assistant, the Oracle Net Manager is written in
Java, provides the same look and feel across platforms, and is typically first accessed
from the installer. The Oracle Net configuration files have a very specific syntax with
multiple levels of nested brackets. Using the Oracle Net Manager allows you to avoid
the errors that are common to hand-coded files. This utility, which automates the
configuration of various Oracle Net components, is shown in Figure 3-4 as it appears
in Oracle Database 11g.

Debugging Network Problems
If you??™re having a problem with your network, one of the first steps toward debugging
the problem is to check that the Oracle Net files were generated, not hand-coded. If
you??™re in doubt, back up the current configuration files and use the Oracle Net Manager
to regenerate them. In fact, when Oracle Support assists customers with Oracle
Net problems, one of the first questions they ask is whether or not the files were
handcoded.
