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
- StandardChannel
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
