Understanding Network Channels
Creating and Configuring WebLogic Server Domains 11-3
What is a Channel?
A Network Channel is a configurable resource that defines the attributes of a network
connection to WebLogic Server. For instance, a Network Channel can define:
! The protocol the connection supports.
! The listen address.
! The listen ports for secure and non-secure communication.
! Connection properties such as the login timeout value and maximum message
sizes.
! Whether or not the connection supports tunneling.
! Whether the connection can be used to communicate with other WebLogic
Server instances in the domain, or used only for communication with clients.
Rules for Configuring Channels
Follow these guidelines when configuring a channel.
! A channel can be assigned to a single server instance.
! You can assign multiple channels to a server instance.
! Each channels assigned to a particular server instance must have a unique
combination of Listen Address, Listen Port, and Protocol.
! If you assign non-SSL and SSL channels to the same server instance, make sure
that they do not use the same port number.
Custom Channels Can Inherit Default Channel Attributes
If you do not assign a channel to a server instance, it uses WebLogic Server’s default
channel, which is automatically configured by WebLogic Server, based on the
attributes in
ServerMBean or SSLMBean. The default channel is described in “The
Default Network Channel” on page 11-7.
