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.

Attributes

This section describes the following attributes:


CachingDisabled

Private property that disables caching in proxies.

       
Privileges Read only
Typeboolean
Redeploy or Restart required Changes take effect after you redeploy the module or restart the server.

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.

       
Privileges Read/Write
Typeint
Default Value1000
Minimum value0
Maximum value2147483647

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.

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.

   
Operation Name"addTarget"
ParametersObject [] {  target }

where:

  • target is an object of type weblogic.management.configuration.TargetMBean that specifies:

    The feature to be added to the Target attribute

SignatureString [] { "weblogic.management.configuration.TargetMBean" }
Returns boolean
Exceptions
  • javax.management.InvalidAttributeValueException
  • weblogic.management.DistributedManagementException

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

   
Operation Name"freezeCurrentValue"
ParametersObject [] {  attributeName }

where:

  • attributeName is an object of type java.lang.String that specifies:

    attributeName

SignatureString [] { "java.lang.String" }
Returns void
Exceptions
  • javax.management.AttributeNotFoundException
  • javax.management.MBeanException

isSet

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

   
Operation Name"isSet"
ParametersObject [] {  propertyName }

where:

  • propertyName is an object of type java.lang.String that specifies:

    property to check

SignatureString [] { "java.lang.String" }
Returns boolean

removeTarget

Removes the value of the addTarget attribute.

For more information, see:

   
Operation Name"removeTarget"
ParametersObject [] {  target }

where:

  • target is an object of type weblogic.management.configuration.TargetMBean that specifies:

    target

SignatureString [] { "weblogic.management.configuration.TargetMBean" }
Returns boolean
Exceptions
  • javax.management.InvalidAttributeValueException
  • weblogic.management.DistributedManagementException

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

   
Operation Name"restoreDefaultValue"
ParametersObject [] {  attributeName }

where:

  • attributeName is an object of type java.lang.String that specifies:

    attributeName

SignatureString [] { "java.lang.String" }
Returns void
Exceptions
  • javax.management.AttributeNotFoundException

unSet

Restore the given property to its default value.

   
Operation Name"unSet"
ParametersObject [] {  propertyName }

where:

  • propertyName is an object of type java.lang.String that specifies:

    property to restore

SignatureString [] { "java.lang.String" }
Returns void
