WorkManagerMBean

Overview

Configuration MBean representing WorkManager parameters. A WorkManager configuration can have a RequestClass(FairShare, ResponseTime, ContextBased), MinThreadsConstraint, MaxThreadsConstraint, Capacity and ShutdownTrigger. All these are optional and need to be configured as needed. An empty WorkManager without configuration gets its own default fair share. The default fair share value is 50.

This section describes attributes that provide access to other MBeans.

Capacity

The total number of requests that can be queued or executing before WebLogic Server begins rejecting requests.

For more information, see:

• CapacityMBean

ContextRequestClass

The mapping of Request Classes to security names and groups.

• ContextRequestClassMBean

FairShareRequestClass

• FairShareRequestClassMBean

MaxThreadsConstraint

The maximum number of concurrent threads that can be allocated to execute requests.

For more information, see:

• MaxThreadsConstraintMBean

MinThreadsConstraint

The minimum number of threads allocated to resolve deadlocks.

For more information, see:

• MinThreadsConstraintMBean

ResponseTimeRequestClass

The response time goal (in milliseconds).

For more information, see:

• ResponseTimeRequestClassMBean

Targets

You must select a target on which an MBean will be deployed from this list of the targets in the current domain on which this item can be deployed. Targets must be either servers or clusters. The deployment will only occur once if deployments overlap.

WorkManagerShutdownTrigger

Configure a shutdown trigger for this WorkManager. Specifies the condition to be used to shutdown the WorkManager. The Server health monitoring periodically checks to see if the conidtion is met and shuts down the work manager if needed.

Attributes

This section describes the following attributes:

CachingDisabled

Private property that disables caching in proxies.

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.

IgnoreStuckThreads

Specifies whether this Work Manager ignores "stuck" threads. Typically, stuck threads will cause the associated Work Manager to take some action: either switching the application to Admin mode, shutting down the server, or shutting down the Work Manager. If this flag is set, then no thread in this Work Manager is ever considered stuck.

If you do not explicitly specify IGNORE_STUCK_THREADS=TRUE, the default behavior is that upon encountering stuck threads, the server will take one of the aforementioned actions.

MBeanInfo

Returns the MBean info for this MBean.

Deprecated.

Name

The user-specified name of this MBean instance.

This name is included as one of the key properties in the MBean's javax.management.ObjectName:
Name=user-specified-name

Notes

Optional information that you can include to describe this configuration.

WebLogic Sever saves this note in the domain's configuration file (config.xml) as XML PCDATA. All left angle brackets (<) are converted to the XML entity <. Carriage returns/line feeds are preserved.

Note:

If you create or edit a note from the Administration Console, the Administration Console does not preserve carriage returns/line feeds.

ObjectName

Returns the ObjectName under which this MBean is registered in the MBean server.

Deprecated.

Parent

Return the immediate parent for this MBean

Registered

Returns false if the the MBean represented by this object has been unregistered.

Deprecated.

Type

Returns the type of the MBean.

Operations

This section describes the following operations:

addTarget

You can add a target to specify additional servers on which the deployment can be deployed. The targets must be either clusters or servers.

freezeCurrentValue

If the specified attribute has not been set explicitly, and if the attribute has a default value, this operation forces the MBean to persist the default value.

Unless you use this operation, the default value is not saved and is subject to change if you update to a newer release of WebLogic Server. Invoking this operation isolates this MBean from the effects of such changes.

Note:

To insure that you are freezing the default value, invoke the restoreDefaultValue operation before you invoke this.

This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute for which some other value has been set.

Deprecated. 9.0.0.0

isSet

Returns true if the specified attribute has been set explicitly in this MBean instance.

removeTarget

Removes the value of the addTarget attribute.

For more information, see:

• addTarget

restoreDefaultValue

If the specified attribute has a default value, this operation removes any value that has been set explicitly and causes the attribute to use the default value.

Default values are subject to change if you update to a newer release of WebLogic Server. To prevent the value from changing if you update to a newer release, invoke the freezeCurrentValue operation.

This operation has no effect if you invoke it on an attribute that does not provide a default value or on an attribute that is already using the default.

Deprecated. 9.0.0.0

unSet

Restore the given property to its default value.
