This MBean defines the minimum number of concurrent threads that should allocated to this constraint provided there are enough pending requests.
Multiple WorkManagers can share a common MinThreadsConstraint. MinThreadsConstraint perform their own bookkeeping and demand a thread when the constraint is not met and there are enough requests.
MinThreadsConstraint should be used to tell the WebLogic Server that a certain number of minimum threads are necessary to prevent server to server deadlocks. Although the server is self-tuning, specifying MinThreadsConstraint ensures that the server guarantees minimum threads to avoid the distributed deadlocks.

In addition to accessing this MBean by invoking a factory method, you can also access this MBean from the following MBean attributes:

| Access Points Inherited from DeploymentMBean |
Because this MBean extends or implements DeploymentMBean, you can also access this MBean by retrieving DeploymentMBeans. The following attributes contain DeploymentMBeans and its subtypes:

This section describes attributes that provide access to other MBeans.

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.
| Privileges | Read/Write |
| Type | TargetMBean[] |
| Relationship type: | Reference. |
This section describes the following attributes:
Private property that disables caching in proxies.
| Privileges | Read only |
| Type | boolean |
| Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server. |
Minimum number of concurrent threads executing requests that share this constraint.
A count of 0 or -1 is treated as if the constraint is not present. This means that the constraint is ignored for these two values. A count > 0 can be dynamically changed to 0 to indicate that constraint enforcement is no longer needed.
| Available Since | Release 9.0.0.0 |
| Privileges | Read/Write |
| Type | int |
| Default Value | -1 |
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 |
| Type | int |
| Default Value | 1000 |
| Minimum value | 0 |
| Maximum value | 2147483647 |
Returns the MBean info for this MBean.
Deprecated.
| Privileges | Read only |
| Type | javax.management.MBeanInfo |
| Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server. |
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
| Privileges | Read/Write |
| Type | java.lang.String |
Optional information that you can include to describe this configuration.
WebLogic Server 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.
If you create or edit a note from the Administration Console, the Administration Console does not preserve carriage returns/line feeds.
| Privileges | Read/Write |
| Type | java.lang.String |
Returns the ObjectName under which this MBean is registered in the MBean server.
Deprecated.
| Privileges | Read only |
| Type | weblogic.management.WebLogicObjectName |
| Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server. |
Return the immediate parent for this MBean
| Privileges | Read/Write |
| Type |
Returns false if the MBean represented by this object has been unregistered.
Deprecated.
| Privileges | Read only |
| Type | boolean |
| Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server. |
Returns the type of the MBean.

This section describes the following operations:
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" |
| Parameters | Object [] { target }
where:
|
| Signature | String [] {
"weblogic.management.configuration.TargetMBean" } |
| Returns |
boolean
|
| Exceptions |
|
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.
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.
| Operation Name | "freezeCurrentValue" |
| Parameters | Object [] { attributeName }
where:
|
| Signature | String [] {
"java.lang.String" } |
| Returns |
void
|
| Exceptions |
|
Returns true if the specified attribute has been set explicitly in this MBean instance.
| Operation Name | "isSet" |
| Parameters | Object [] { propertyName }
where:
|
| Signature | String [] {
"java.lang.String" } |
| Returns |
boolean
|
Removes the value of the addTarget attribute.
For more information, see:
| Operation Name | "removeTarget" |
| Parameters | Object [] { target }
where:
|
| Signature | String [] {
"weblogic.management.configuration.TargetMBean" } |
| Returns |
boolean
|
| Exceptions |
|
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.
| Operation Name | "restoreDefaultValue" |
| Parameters | Object [] { attributeName }
where:
|
| Signature | String [] {
"java.lang.String" } |
| Returns |
void
|
| Exceptions |
|
Restore the given property to its default value.
| Operation Name | "unSet" |
| Parameters | Object [] { propertyName }
where:
|
| Signature | String [] {
"java.lang.String" } |
| Returns |
void
