Figure 4-2
This illustration depicts a directory information tree. The tree has two branches. The branch on the right proceeds downward as follows: beginning from the top node, called dc=com, to dc=acme, to dc=jp, to cn=OracleContext, and, finally, to cn=sales and cn=db1. The left branch proceeds similarly: from dc=com, to dc=acme, and, finally to dc=us.

The entry cn=db1 contains the following connect descriptor information:

(DESCRIPTION=
(ADDRESS=(PROTOCOL=tcp)(HOST=db1-server)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=db1.jp.acme.com)))
