13.1.1 Creating a List of Listener Protocol Addresses

A database service may be accessed by more than one network route, or protocol address. In the following example, sales.us.example.com can connect to the sales.us.example.com service using listeners on either sales1-server or sales2-server.

sales.us.example.com=
 (DESCRIPTION=
  (ADDRESS_LIST=
    (ADDRESS=(PROTOCOL=tcp)(HOST=sales1-server)(PORT=1521))
    (ADDRESS=(PROTOCOL=tcp)(HOST=sales2-server)(PORT=1521)))
  (CONNECT_DATA=
    (SERVICE_NAME=sales.us.example.com)))

To add a network protocol address to an existing network service name or database service, use one of the following procedures:

Adding a Network Protocol Using Oracle Enterprise Manager Cloud Control

The following procedure describes how to add a network protocol to an existing network service name or database service using Oracle Enterprise Manager Cloud Control:

  1. Access the Directory Naming or Local Naming page in Oracle Enterprise Manager Cloud Control:

    1. Access the Net Services Administration page in Oracle Enterprise Manager Cloud Control.

    2. Select Local Naming or Directory Naming from the Administer list, and then select the Oracle home for the directory server or the location of the local configuration files.

    3. Click Go.

      The Local Naming or Directory Naming page appears.

  2. Select the directory service or network service name.

    • For Local Naming, select a network service from the list, and then click Edit.

    • For Directory Naming, perform a search of the network service name in the Simple Search section, then select the network service or database service from the Results list, and then click Edit.

  3. In the Addresses section, click Add.

    The Add Address page appears.

  4. From the Protocol list, select the protocol which the listener is configured to listen. This protocol must also be installed on the client.

  5. Enter the appropriate parameter information for the selected protocol in the fields provided.

    See Also:

    Oracle Database Net Services Reference for protocol parameter settings

  6. (Optional) In the Advanced Parameters section, specify the I/O buffer space limit for send and receive operations of sessions in the Total Send Buffer Size and Total Receive Buffer Size fields.

    See Also:

    "Configuring I/O Buffer Space" for additional information about buffer space

  7. Click OK.

    The protocol address is added to the Addresses section.

  8. Click OK to update the address information.

Adding a Network Protocol Using Oracle Net Manager

The following procedure describes how to add a network protocol to an existing network service name or database service using Oracle Net Manager:

  1. Start Oracle Net Manager.

  2. In the navigator pane, select Service Naming from the Directory or Local menus.

  3. Select either the network service name or a database service.

    The right pane displays the current destination service and address list.

  4. In the Address Configuration box, click the plus sign (+) to add a new address.

    A new Address tab appears:

    1. Select the protocol and enter appropriate address information.

      See Also:

      Oracle Database Net Services Reference for details about protocol address parameters

    2. (Optional) On the Address tab, click Advanced to specify the I/O buffer space limit for send and receive operations of sessions in the Total Send Buffer Size and Total Receive Buffer Size fields.

      See Also:

      "Configuring I/O Buffer Space " for additional information about buffer space

    3. Order the protocol addresses using the left-arrow and right-arrow buttons. This will order the addresses in the protocol address list. Unless multiple address options are configured, the first address in the list is contacted.

  5. Select Save Network Configuration from the File menu.
