NetworkChannel

 

Description

This MBean defines a network channel. A network channel is used to configure additional ports for a server beyond its default listen ports. Network channels do not support IIOP.

A network channel can be targeted at multiple clusters and servers. Targeting a channel at a cluster targets it at every server that is a member of that cluster. A server can support multiple channels. A server can fine-tune its network channel settings by using a NetworkAccessPointMBean. The NetworkAccessPointMBean also servers to set the listen address and external DNS name that a server uses for a particular channel.

A server serves up to three default listen ports: ServerMBean ListenPort, ServerMBean AdministrationPort, and SSLMBean ListenPort. The default listen ports form implicit channel(s) of weight 50.

A network channel also defines the creation of server-to-server connections. If a server is initiating a new connection to another server, the highest weighted common (same named) channel that supports the desired protocol is used to determine which port to contact.

Attributes

Table 52-1 NetworkChannel attributes

Attribute

Description

Range of Values and Default

AcceptBacklog

Deprecated. Allowed backlog of connection requests on the listen port(s). Individual servers may override this value using a NetworkAccessPointMBean. Setting the backlog to 0 may prevent accepting any incoming connection on some of the OS.

Default: 50

Minimum: 0

COMEnabled

Deprecated. Indicates whether plaintext (non-SSL) COM traffic is enabled.

Default: false

Secure value: false

ChannelWeight

Deprecated. A weight to give this channel when creating server-to-server connections.

Default: 50

Minimum: 1

Maximum: 100

ClusterAddress

Deprecated. This channel's cluster address. If this is not set, the cluster address from the cluster configuration is used in its place.

Required: no

CompleteCOMMessageTimeout

Deprecated. The maximum number of seconds spent waiting for a complete COM 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. Individual servers may override this value using a NetworkAccessPointMBean.

Units: seconds

Default: 60

Secure value: 60

Minimum: 0

Maximum: 480

CompleteHTTPMessageTimeout

Deprecated. The maximum number of seconds spent waiting for a complete HTTP 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. Individual servers may override this value using a NetworkAccessPointMBean.

Units: seconds

Default: 60

Secure value: 60

Minimum: 0

Maximum: 480

CompleteT3MessageTimeout

Deprecated. The maximum number of seconds spent waiting for a complete T3 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. Individual servers may override this value using a NetworkAccessPointMBean.

Units: seconds

Default: 60

Secure value: 60

Minimum: 0

Maximum: 480

DeploymentOrder

A priority that the server uses to determine when it deploys an item. The priority is relative to other deployable items of the same type. For example, the server prioritizes and deploys all EJBs before it prioritizes and deploys startup classes.

Items with the lowest Deployment Order value are deployed first. There is no guarantee on the order of deployments with equal Deployment Order values. There is no guarantee of ordering across clusters.

Default: 1000

Minimum: 0

Maximum: 231-1

Description

Deprecated. Optional short description of this channel for console display purposes. For long descriptions, use the "Notes" field.

Required: no

HTTPEnabled

Deprecated. Whether or not plaintext (non-SSL) HTTP traffic is enabled.

Default: false

Secure value: false

HTTPSEnabled

Deprecated. Whether or not secure (SSL) HTTP traffic is enabled.

Default: false

Secure value: true

ListenPort

Deprecated. The plaintext (non-SSL) listen port for the channel. Individual servers may override this value, but may not enable the port if disabled here and may not disable the port if enabled here. Individual servers may override this value using a NetworkAccessPointMBean.

Default: 8001

Minimum: 1

Maximum: 65534

ListenPortEnabled

Deprecated. Whether or not plaintext port is enabled for the channel.

Default: false

Secure value: false

LoginTimeoutMillis

Deprecated. The login timeout for the server, in milliseconds. This value must be equal to or greater than 0. Individual servers may override this value using a NetworkAccessPointMBean.

Units: milliseconds

Default: 5000

Secure value: 5000

Minimum: 0

Maximum: 100000

LoginTimeoutMillisSSL

Deprecated. Duration allowed for an SSL login sequence. If the duration is exceeded, the login is timed out. 0 to disable. Individual servers may override this value using a NetworkAccessPointMBean.

Units: milliseconds

Default: 25000

Secure value: 25000

Minimum: 0

Maximum: 231-1

MaxCOMMessageSize

Deprecated. The maximum COM 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. Individual servers may override this value using a NetworkAccessPointMBean.

Units: bytes

Default: 10000000

Secure value: 10000000

Minimum: 4096

Maximum: 2000000000
