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()

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

   • getMaxCOMMessageSize
   • getMaxHTTPMessageSize
   • getMaxIIOPessageSize
   • getMaxT3MessageSize

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.

A client can set this value using the -Dweblogic.MaxMessageSize property.

Returns:

The maxMessageSize value

See Also:

NetworkAccessPointMBean

setMaxMessageSize

void setMaxMessageSize(int maxsize)
                       throws InvalidAttributeValueException,

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()

setMaxT3MessageSize

void setMaxT3MessageSize(int maxsize)

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

getMaxHTTPMessageSize

int getMaxHTTPMessageSize()

Deprecated. 8.1.0.0 use NetworkAccessPointMBean.getMaxMessageSize()

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 WebLogic 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

setStuckThreadMaxTime

void setStuckThreadMaxTime(int seconds)
                           throws InvalidAttributeValueException

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

See Also:

KernelMBean.getStuckThreadMaxTime()

getStuckThreadTimerInterval

Specifies whether self-tuning thread pool should increment thread count by CPU count.

Since:

10.3.4.0

isAddWorkManagerThreadsByCpuCount

boolean isAddWorkManagerThreadsByCpuCount()

Enables increased efficiency of the self-tuning thread pool by aligning it with the Exalogic processor architecture threading capabilities. Use only when configuring a WebLogic domain for Oracle Exalogic.

• Enabling this attribute increases efficiency during I/O in environments with high network throughput.
• Disabling this attribute allows the thread pool to self-tune to match the demand of the workload at the expense of longer ramp up time.

Since:

10.3.4.0

setUseConcurrentQueueForRequestManager

void setUseConcurrentQueueForRequestManager(boolean flag)

Specifies if self-tuning should use buffer queue to park incoming requests.

Since:

10.3.6.0

Since:

10.3.6.0

getCompleteWriteTimeout

int getCompleteWriteTimeout()

The maximum number of seconds that this server waits for a complete HTTP response to be sent.

A value of 0 disables the complete write timeout. The default value is derived from the CompleteHTTPMessageTimeout. If it is -1, then the CompleteMessageTimeout value is used for the default value.

Returns:

The completeWriteTimeout value

Since:

12.1.2.0

setCompleteWriteTimeout

void setCompleteWriteTimeout(int seconds)
                             throws InvalidAttributeValueException,
                                    DistributedManagementException

setUseDetailedThreadName

void setUseDetailedThreadName(boolean flag)

Specifies whether to include detail information in self-tuning thread pool thread names.

Since:

12.1.2.0

isUseDetailedThreadName

boolean isUseDetailedThreadName()

Specifies whether to includes detailed information in self-tuning thread pool thread names. Setting this flag as true would include additional information, such as the name of the Work Manager for which the execute thread is executing the task, but at the expense of overhead in keeping the thread name updated with such information.

Since:

12.1.2.0

setUseEnhancedPriorityQueueForRequestManager

void setUseEnhancedPriorityQueueForRequestManager(boolean flag)

Specifies if self-tuning should use the enhanced ConcurrentCalendarQueue as the priority based queue for pending requests that are waiting for a thread.

This attribute should be enabled only in an Oracle Exalogic environment.

Since:

12.1.2.0

isUseEnhancedPriorityQueueForRequestManager

boolean isUseEnhancedPriorityQueueForRequestManager()

Reduces lock contention by using the enhanced ConcurrentCalendarQueue as the priority based queue for pending requests that are waiting for a thread.

This attribute should be enabled only in an Oracle Exalogic environment.

Since:

12.1.2.0

setAllowShrinkingPriorityRequestQueue

void setAllowShrinkingPriorityRequestQueue(boolean flag)

Specifies if self-tuning should allow shrinking of its priority based queue for pending requests after it has grown in size due to busy workload, and whether it should try to purge work requests that have already been picked up for processing due to minimum threads constraints before growing the queue.

Since:

12.1.3.0

isAllowShrinkingPriorityRequestQueue

boolean isAllowShrinkingPriorityRequestQueue()

Specifies whether self-tuning should allow shrinking of its priority based queue for pending requests after it has grown in size due to busy workload, and whether it should try to purge work requests that have already been picked up for processing due to minimum threads constraints before growing the queue. Setting this to true would help reduce memory footprint after the busy work period has ended, at the expense of the overhead of growing the request queue again at the next period of busy workload. It would also help to reduce the amount of memory allocated for the request queue, at the expense of the overhead required in purging already processed work requests from the queue.

Since:

12.1.3.0

setUseEnhancedIncrementAdvisor

void setUseEnhancedIncrementAdvisor(boolean flag)

Specifies if self-tuning should use the enhanced IncrementAdvisor implementation that uses a different algorithm to adjust the size of the self-tuning thread pool.

Since:

12.1.3.0

isUseEnhancedIncrementAdvisor

boolean isUseEnhancedIncrementAdvisor()

Specifies whether self-tuning should use the enhanced IncrementAdvisor implementation that uses a different algorithm to adjust the size of the self-tuning thread pool.

Since:

12.1.3.0

setEagerThreadLocalCleanup

void setEagerThreadLocalCleanup(boolean flag)

Specifies whether to clean up all ThreadLocals storage from self-tuning thread pool threads after they have finished processing each work request. Setting this to true would ensure that all thread pool threads would have no leftover ThreadLocal values from previous requests when running work for a new request, at the expense of the overhead of cleaning up ThreadLocal storage after each work request and reestablishing ThreadLocal values for each new request. Some applications may cache objects that are expensive to create in the ThreadLocal storage. Thus cleaning up ThreadLocal values after each request may have a negative impact on the performance of those applications. By default, the self-tuning thread pool only cleans up ThreadLocal storage in its threads after an application is undeployed to prevent ClassLoader memory leak.

Since:

12.2.1.0

isEagerThreadLocalCleanup

boolean isEagerThreadLocalCleanup()

Specifies whether to clean up all ThreadLocals storage from self-tuning thread pool threads after they have finished processing each work request. By default, the self-tuning thread pool only cleans up ThreadLocal storage in its threads after an application is undeployed to avoid ClassLoader memory leak.

Since:

12.2.1.0
