EJB stubs for load balancing and failover in a cluster • 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 A weight to give this channel when multiple channels are available for internal server-to-server connections Innocent Matinya ([email protected]ฺcom) has a non-transferable license to use this Student Guideฺ Unauthorized reproduction or distribution prohibitedฺ Copyright© 2019, Oracle and/or its affiliatesฺ

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, Copyright © 2016, Oracle and/or its affiliates. All rights reserved. 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
