WebLogic Server Configuration Reference

# NetworkAccessPoint

# Description

A server can specifiy additional network connections by using a NetworkAccessPointMBean. The NetworkAccessPointMBean is also used to set the listen address and external DNS name that a server uses for a particular channel.

Table 51-1 NetworkAccessPoint attributes

Attribute | Description | Range of Values and Default
--- | --- | ---
AcceptBacklog | Allowed backlog of connection requests on the listen port. -1 implies that this value is inherited from the channel. | Admin Console field label: Accept Backlog Default: -1 Minimum: -1
ChannelWeight | A weight to give this channel when creating server-to-server connections. | Default: 50 Minimum: 1 Maximum: 100
ClusterAddress | This channel's cluster address. If this is not set, the public address is used and if this is not set then the cluster address from the cluster configuration is used in its place. | Admin Console field label: Cluster Address Required: no
CompleteMessageTimeout | The maximum number of seconds spent waiting for a complete message to be received. This attribute 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. -1 implies that this value is inherited from the channel. | Admin Console field label: Complete Message Timeout Units: seconds Default: -1 Minimum: -1 Maximum: 480
HttpEnabledForThisProtocol | Whether or not this port will accept HTTP requests. HTTP is generally required by binary protocols for downloading stubs and other resources. | Admin Console field label: HTTP Enabled for This Protocol Default: true
IdleConnectionTimeout | The maximum number of seconds an connection is allowed to be idle before it is closed by the server. This attribute helps guard against server deadlock through too many open connections. -1 implies that this value is inherited from the default channel. | Admin Console field label: Idle Connection Timeout Units: seconds Default: -1 Minimum: -1
ListenAddress | A value of null indicates that this value is inherited from the server. | Admin Console field label: Listen Address Required: no
ListenPort | The listen port for the channel. -1 implies that this value is inherited from the server. | Admin Console field label: Listen Port Default: -1
LoginTimeoutMillis | The login timeout for the server, in milliseconds. This value must be equal to or greater than 0. -1 implies that this value is inherited from the channel. | Admin Console field label: Login Timeout Units: milliseconds Default: -1 Minimum: -1 Maximum: 100000
MaxMessageSize | Specify the maximum message size allowable in a message header. This attribute 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. | Admin Console field label: Maximum Message Size Units: bytes Default: 10000000
Name | The name of this NetworkAccessPoint. | Admin Console field label: Name Required: no Default: <unknown>
Notes | Optional information that you can include to describe this configuration. | Required: no
OutboundEnabled | Whether or not new server-to-server connections may consider this channel when initiating a connection. This is only relevant if the connection needs to be bound to the channel's listen address. By default connections are initiated using a local address selected by the underlying hardware. This will only work for binary protocols which support both outbound and inbound traffic. | Admin Console field label: Outbound Enabled Default: false
Protocol | The protocol that will be discriminated by this NetworkAccessPoint. | Admin Console field label: Protocol Required: no Default: t3
PublicAddress | The external address for the current server, which will be sent to clients. This will be required for the configurations in which need to cross a firewall doing Network Address Translation. This property supercedes ExternalDNSName. If unset then this value is inherited, first from the ListenAddress, and then from the ServerMBean. | Admin Console field label: External Listen Address Required: no
PublicPort | The external listen port for the channel. If unset then this value is inherited, first from the ListenPort, and then from the ServerMBean. | Admin Console field label: External Listen Port Default: -1
TunnelingClientPingSecs | Interval (in seconds) at which to ping an http-tunneled client to see if its still alive. -1 implies that this value is inherited from the channel. | Admin Console field label: Tunneling Client Ping Units: seconds Default: -1
TunnelingClientTimeoutSecs | Duration (in seconds) after which a missing http-tunneled client is considered dead. -1 implies that this value is inherited from the channel. | Admin Console field label: Tunneling Client Timeout Units: seconds Default: -1
TunnelingEnabled | Enables tunneling for those protocols that support tunneling. Each channel explicitly defaults to off and you will need to explicitly configure it to be on if you require tunneling. This value is not inherited from the Server. | Admin Console field label: Tunneling Enabled Default: false
