• Accept Backlog: The number of backlogged, new TCP connection requests that this
network channel allows
• Maximum Backoff Between Failures: The maximum wait time (in seconds) between
failures while accepting client connections
• Idle Connection Timeout: The maximum amount of time (in seconds) that a connection
is allowed to be idle before it is closed by this network channel. This timeout helps guard
against server deadlock through too many open connections.
• Maximum Message Size: This maximum attempts to prevent a denial of service attack
whereby a caller sends very large messages, thereby keeping the server from
responding quickly to other requests
• Channel Weight: A weight to give this channel when multiple channels are available for
Oracle WebLogic Server 12 c : Administration I 11 - 15

Administration Port
• The domain’s Administration Port is an alternative to creating
a custom network channel with the explicit “admin” protocol on
every server.
• This feature creates an implicit administration channel on
every server using:
– The listen address of the server’s default channel
– The same admin port number (entered by you) for each server
• Administration channels require SSL to be configured on each
server.
You can define an optional administration port for your domain. When configured, the
administration port is used by each managed server in the domain exclusively for
communication with the domain’s administration server. If an administration port is enabled,

WebLogic Server automatically generates an administration channel based on the port
settings upon server instance startup.
The administration port accepts only secure, SSL traffic, and all connections via the port
require authentication. The Administration Server and all managed servers in your domain
must be configured with support for the SSL protocol. Managed servers that do not support
SSL cannot connect with the administration server during startup. You will have to disable the
