Configuring Local Naming for Connecting
to Other Databases
In this section you configure local naming to connect to another
database. You can configure local naming using Net Manager on a client PC or
using Enterprise Manager as described in the following sections:
You must configure a client machine so it can connect to an
Oracle database. You must first install Oracle Database client software, which
includes Oracle Net software. Once you have installed Oracle Net, you can use
Oracle Net Manager to configure a net service name using the local naming method
as follows:
1.
On Windows, start Oracle Net Manager by clicking:
Start->Programs->Oracle->Configuration and
MigrationTools->Net Manager
On UNIX or Linux, invoke Oracle Net Manager by entering
netmgr at the command
line.

Click the (plus) + on the left hand side of the page.
3.
The Net Service Name Wizard: Welcome window appears. Enter a
net service name. Click Next.

You can accept the default TCP/IP(Internet Protocol). The database
listener must be configured to use the same network protocol. Click Next.
5.
Enter the host name of the database machine. Click Next.
6.
Enter the database service name. In addition, select
a Connection Type, either Shared or Dedicated. If you are unsure
or would like to use the default database connection type, select Database
Default. Click Next.
7.
The last window of the wizard enables you to test the
connection using the information you entered. Click Test.

The wizard tells you if the connection test succeed
or not. Click Close.
12.
Click Finish.
