weblogic.management.configuration
Interface KernelMBean

All Superinterfaces:

ConfigurationMBean

All Known Subinterfaces:

ServerMBean

public interface KernelMBean
extends ConfigurationMBean

This bean represents the configuration of the core message passing kernel on both WebLogic clients and servers.

ServerMBean extends this bean to represent the configuration of a server.

Deprecation of MBeanHome and Type-Safe Interfaces

This is a type-safe interface for a WebLogic Server MBean, which you can import into your client classes and access through weblogic.management.MBeanHome. As of 9.0, the MBeanHome interface and all type-safe interfaces for WebLogic Server MBeans are deprecated. Instead, client classes that interact with WebLogic Server MBeans should use standard JMX design patterns in which clients use the javax.management.MBeanServerConnection interface to discover MBeans, attributes, and attribute types at runtime.

isOutboundEnabled

boolean isOutboundEnabled()

Specifies whether new server-to-server connections may consider the default server channel when initiating a connection. This is only relevant if the connection needs to be bound to the default 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. For the default channel this is usually what is wanted for IP-routing to be effective. Note that since the default is false, other outbound channels will be considered in preference to the default channel.

Default administration channels, created when the domain-wide administration port is turned on, are always considered and bound when initiating an administrative connection. To allow IP-routing for administration traffic create custom admin with isOutboundEnabled set to false instead of enabling the domain-wide ADMIN port.

Returns:

The outboundEnabled value

See Also:

NetworkAccessPointMBean.isOutboundEnabled()

Default Value:

false

Returns:

The OutboundPrivateKeyEnabled value

See Also:

KernelMBean.isOutboundEnabled()

Default Value:

false

setOutboundPrivateKeyEnabled

void setOutboundPrivateKeyEnabled(boolean enabled)
                                  throws InvalidAttributeValueException

Sets the value of the OutboundPrivateKeyEnabled attribute.

Parameters:

getMaxMessageSize

int getMaxMessageSize()

The maximum number of bytes allowed in messages that are received over all supported protocols, unless overridden by a protocol-specific setting or a custom channel setting.

The order of precedence for setting message size maximums is as follows:

1. A channel-wide maximum in a custom network channel.

2. A protocol-specific setting in the default network channel.
   See

   • MaxCOMMessageSize
   • MaxHTTPMessageSize
   • MaxIIOPessageSize
   • MaxT3MessageSize

3. The message maximum in this attribute.

This maximum message size helps guard against a denial of service attack in which a caller attempts to force the server to allocate more memory than is available thereby keeping the server from responding quickly to other requests.

Returns:

The maxMessageSize value

See Also:

NetworkAccessPointMBean

Default Value:

10000000

Maximum Value:

2000000000

Minimum Value:

getMaxT3MessageSize

int getMaxT3MessageSize()

Deprecated. 8.1.0.0 use NetworkAccessPointMBean.getMaxMessageSize()

The maximum number of bytes allowed in messages that are received over the T3 protocol. If you configure custom network channels for this server, each channel can override this maximum message size.

This maximum message size helps guard against a denial of service attack in which 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 value of -1 causes the T3 protocol to use the maximums that are specified elsewhere along the order of precedence.

Returns:

The maxT3MessageSize value

See Also:

KernelMBean.getMaxMessageSize(), NetworkAccessPointMBean.getMaxMessageSize()

Default Value:

-1

setMaxT3MessageSize

isSocketBufferSizeAsChunkSize

boolean isSocketBufferSizeAsChunkSize()

Specifies whether the server's buffer size for sending or receiving data through a raw socket should be set to 4KB.

Otherwise, the server does not impose a limit to the buffer size and defers to the operating system. This option is useful only on some operating systems for improving performance. It should be disabled in most environments.

Returns:

The SocketBufferSizeAsChunkSize value

Default Value:

false

getMaxHTTPMessageSize

int getMaxHTTPMessageSize()

Deprecated. 8.1.0.0 use NetworkAccessPointMBean.getMaxMessageSize()

The maximum number of bytes allowed in messages that are received over the HTTP protocol. If you configure custom network channels for this server, each channel can override this maximum message size.

This maximum message size helps guard against a denial of service attack in which 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 value of -1 causes the HTTP protocol to use the maximums that are specified elsewhere along the order of precedence.

Returns:

The maxHTTPMessageSize value

See Also:

KernelMBean.getMaxMessageSize(), NetworkAccessPointMBean.getMaxMessageSize()

Default Value:

-1

This maximum message size helps guard against a denial of service attack in which 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 value of -1 causes the COM protocol to use the maximums that are specified elsewhere along the order of precedence.

Returns:

The maxCOMMessageSize value

getCompleteMessageTimeout

int getCompleteMessageTimeout()

The maximum number of seconds that this server waits for a complete message to be received. If you configure network channels for this server, each channel can override this message timeout.

getStuckThreadMaxTime

int getStuckThreadMaxTime()

Deprecated. 9.0.0.0 replaced by ServerFailureTriggerMBean.getMaxStuckThreadTime()

The number of seconds that a thread must be continually working before this server considers the thread stuck.

For example, if you set this to 600 seconds, WebLogic Server considers a thread to be "stuck" after 600 seconds of continuous use.

In Web Logic Server 9.x and later, it is recommended that you use the ServerFailureTriggerMBean in the OverloadProtectionMBean. The ServerFailureTriggerMBean transitions the server to a FAILED state after the specified number of stuck threads are detected. The OverloadProtectionMBean has options to suspend or shutdown a failed server.

Returns:

The stuckThreadMaxTime value

Default Value:

600

Maximum Value:

java.lang.Integer.MAX_VALUE

Minimum Value:

0

setStuckThreadMaxTime

void setStuckThreadMaxTime(int seconds)

Deprecated. 9.0.0.0 replaced by ServerFailureTriggerMBean.setMaxStuckThreadTime()

Sets the value of the StuckThreadMaxTime attribute.

From WLS 9.0, it is recommended to used the ServerFailureTriggerMBean present in OverloadProtectionMBean. Setting the ServerFailureTriggerMBean transitions the server into FAILED state after the configured number of stuck threads are detected. OverloadProtectionMBean has options to suspend, shutdown a failed server.

Parameters:

seconds - The new stuckThreadMaxTime value

Throws:

InvalidAttributeValueException
