Domain Network Configuration

In a simple server setup, you usually would assign a single network address and port number to a WebLogic instance and use this address and port for all communication with the server. Each different protocol supported by WebLogic is then multiplexed onto the same host address and port. You can tune the setup by specifying various connection and messaging timeouts and enabling tunneling. This default network configuration for a server is called the default network channel (although not explicitly in the Administration Console). You can further refine this basic setup by creating an administration channel, which provides an additional port exclusively for administration traffic. In this way, all administration traffic will use the dedicated administration port, while all other traffic will use the default network channel. This separation provides many benefits, including increased reliability and security of administration traffic.

Finally, WebLogic lets you exploit a far more complex network configuration that assigns different protocols to different addresses and ports on the same server. You can achieve this by creating custom network channels. Each network channel can be tuned independently and even be assigned different NICs on a multihomed machine.

The Default Network Channel

The most important connection settings for a Managed Server are its listen address and port. These settings form the basis of all communication with the server, using any of ...
