Understanding Network Channels
Creating and Configuring WebLogic Server Domains 11-7
Standard WebLogic Server Channels
WebLogic Server provides pre-configured channels that you do not have to explicitly
define.
! Default channel—Every Managed Server has a default channel.
! Administrative channel—If you configure a domain-wide Administration Port,
WebLogic Server configures an Administrative Channel for each Managed
Server in the domain.
The Default Network Channel
Every WebLogic Server domain has a default channel that is generated automatically
by WebLogic Server. The default channel is based on the Listen Address and Listen
Port defined in the
ServerMBean and SSLMBean. It provides a single Listen Address,
one port for HTTP communication (7001 by default), and one port for HTTPS
communication (7002 by default). You can configure the Listen Address and Listen
Port using the Configuration-->General tab in the Administration Console; the values
you assign are stored in attributes of the
ServerMBean and SSLMBean.
The default configuration may meet your needs if:
! You are installing in a test environment that has simple network requirements.
! Your server uses a single NIC, and the default port numbers provide enough
flexibility for segmenting network traffic in your domain.
Using the default configuration ensures that third-party administration tools remain
compatible with the new installation, because network configuration attributes remain
stored in
ServerMBean and SSLMBean.
Even if you define and use custom Network Channels for your domain, the default
channel settings remain stored in
ServerMBean and SSLMBean,andareusedif
necessary to provide connections to a server instance.
Administrative Channel
You can define an optional administration port for your domain. When configured, the
administration port is used by each Managed Server in the domain for communication
with the domain’s Administration Server.
