This page allows you to define the configuration of this network channel.
A network channel is a configurable resource that defines the attributes of a network connection to WebLogic Server. You can use network channels to manage quality of service, meet varying connection requirements, and improve utilization of your systems and network resources.
Name Description Name
The name of this Network Channel.
The protocol this network channel should use for connections.
The IP address or DNS name this network channel uses to listen for incoming connections. A value of null indicates that the network channel should obtain this value from the server's configuration.
The default TCP port this network channel uses to listen for regular (non-SSL) incoming connections. A value of -1 indicates that the network channel should obtain this value from the server's configuration.
External Listen Address
The IP address or DNS name representing the external identity of this network channel. A value of null indicates that the network channel's Listen Address is also its external address. If the Listen Address is null,the network channel obtains its external identity from the server's configuration.
This is required for the configurations which need to cross a firewall doing Network Address Translation.
External Listen Port
The externally published listen port for this network channel. A value of -1 indicates that the network channel's Listen Port is also its public listen port. If the Listen Port is -1,the network channel obtains its public listen port from the server's configuration.
Specifies whether this channel should be started.
Advanced Configuration Options
Name Description Outbound Enabled
Specifies whether new server-to-server connections may consider this network channel when initiating a connection. This is only relevant if the connection needs to be bound to the network channel's listen address. This will only work for binary protocols that support both outbound and inbound traffic.
When this feature is not enabled, connections are initiated using a local address selected by the underlying hardware.
The default is false.
Outbound channels are selected at runtime either by virtue of the fact of being the only outbound-enabled channel for the required protocol, or by name in
The HTTP protocol is implicitly enabled for all the outbound channels, but you need to use the WLS client library (HTTP client) and set the channel on the connection.
The address this network channel uses to generate EJB handles and failover addresses for use in a cluster. This value is determined according to the following order of precedence:
If the cluster address is specified via the NAPMBean, then that value is used
If this value is not specified, the value of PublicAddress is used.
If PublicAddress is not set, this value is derive from the ClusterAddress attribute of the ClusterMbean.
If ClusterMbean.clusterAddress is not set, this value is derive from the listen address of the NAPMbean.
The number of backlogged, new TCP connection requests that this network channel allows. A value of -1 indicates that the network channel obtains its backlog configuration from the server's configuration.
Maximum Backoff Between Failures
The maximum back off time between failures while accepting client connections. -1 implies that this value is inherited from the server.
HTTP Enabled for This Protocol
Specifies whether HTTP traffic should be allowed over this network channel.
HTTP is generally required by binary protocols for downloading stubs and other resources.
The amount of time that this network channel should wait for a connection before timing out. A value of
0disables network channel login timeout. A value of -1 indicates that the network channel obtains this timeout value from the server's configuration.
Complete Message Timeout
The maximum amount of time this network channel waits for a complete message to be received. A value of
0disables network channel complete message timeout. A value of -1 indicates that the network channel obtains this timeout value from the ServerTemplateMBean.
This timeout helps guard against denial of service attacks in which a caller indicates that they will be sending a message of a certain size which they never finish sending.
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. A value of -1 indicates that the network channel obtains this timeout value from the ServerTemplateMBean.
This timeout helps guard against server deadlock through too many open connections.
The amount of time that this network channel should wait to establish an outbound socket connection before timing out. A value of
0disables network channel connect timeout.
Timeout Connection With Pending Responses
Determines if connections with pending responses are allowed to timeout. It defaults to false. If set to true, the connection will be timed out for this channel if it exceeds the idleConnectionTimeout value.
Note: This setting only applies to IIOP connections.
Specifies whether tunneling via HTTP should be enabled for this network channel. This value is not inherited from the server's configuration.
Tunneling Client Ping
The interval (in seconds) at which this network channel should ping an HTTP-tunneled client to see if its still alive. A value of -1 indicates that the network channel obtains this interval from the ServerTemplateMBean. (Requires you to enable tunneling for the network channel.)
Tunneling Client Timeout
The amount of time (in seconds) after which this network channel considers a missing HTTP-tunneled client to be dead. A value of -1 indicates that the network channel obtains this timeout value from the ServerTemplateMBean. (Requires you to enable tunneling for the network channel.)
Maximum Message Size
The maximum message size allowable in a message header.
This maximum attempts to prevent a denial of service attack whereby a caller attempts to force the server to allocate more memory than is available thereby keeping the server from responding quickly to other requests.
A client can set this value using the
A weight to give this channel when creating server-to-server connections.
Maximum Connected Clients
The maximum number of clients that can be connected on this network channel.
Use Optimized Serialization
Specifies whether to use non-standard object serialization for performance. This option works in different ways for different protocols. In particular under IIOP this option uses Java serialization rather than RMI-IIOP serialization. In general using non-standard serialization is not suitable for interop scenarios and may imply some feature loss.
Enable SDP Protocol
Enables Socket Direct Protocol (SDP) on this channel. Enable this attribute when configuring session replication enhancements for Managed Servers in a WebLogic cluster for Oracle Exalogic.
