Network Addressing Features…

• Adds flexibility to networking configuration:

  • multiple NICs for a single WLS server
  • specific NIC’s or multiple port numbers on a NIC for specific WLS servers
  • multiple IP addresses can be used with each server
  • a single IP address can be used with multiple ports
  • configure the cluster multicast port number independently of the port numbers used by cluster members
  • multiple SSL configurations on one server
  • administration traffic only port

interoperability with previous WLS versions

Network Channels

• define a set of basic attributes of a network connection to WLS.
• can assign multiple channels to a single server (segment network traffic).
• can prioritize internal (non-URL) connections.

• can separate incoming client traffic from internal server to server traffic in a domain.
• “default” channel gets automatically generated when a server is created.

Configuring Network Channels

Navigate to Environment à Servers à Server_Name à Protocols à Channels.

Click on New to create Network Channel

In the Network Channel table, specify the following properties:

 Name:  Protocol

In the Create a new Network Channel page, specify the following properties:

Listen Address

Listen Port

External Listen Address

External Listen Port

Using Channels Example 1: Multiple NICs per server

• Each server has 2 NICs
• Each NIC has one channel, hence there are 2 channels per server
• Types of channels

  • StandardChannel

    • enables HTTP
    • disables other protocols

  • SecureChannel

    • enables HTTPS
    • disables other protocols

Using Channels Example 2: Separate Internal and External traffic:

• AppChannel is common between servers

  • used for internal communications
  • OutgoingEnabled attribute is enabled

• ClientChannel is used for external access

  • clients can only connect to public IP address 192.168.1.500
  • OutgoingEnabled attribute is disabled
