ネット・サービス名設定ファイル(tnsnames.ora)

# This file contains the syntax information for
# the entries to be put in any tnsnames.ora file
# The entries in this file are need based.
# There are no defaults for entries in this file
# that Sqlnet/Net3 use that need to be overridden
#
# Typically you could have two tnsnames.ora files
# in the system, one that is set for the entire system
# and is called the system tnsnames.ora file, and a
# second file that is used by each user locally so that
# he can override the definitions dictated by the system
# tnsnames.ora file.

# The entries in tnsnames.ora are an alternative to using
# the names server with the onames adapter.
# They are a collection of aliases for the addresses that
# the listener(s) is(are) listening for a database or
# several databases.

# The following is the general syntax for any entry in
# a tnsnames.ora file. There could be several such entries
# tailored to the user's needs.
