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 113 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.

  • Types of channels
    • StandardChannel
      • enables HTTP
      • disables other protocols
    • SecureChannel
      • enables HTTPS
      • disables other protocols

119   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
