## Related MBeans

This section describes attributes that provide access to other MBeans. For more information about the MBean hierarchy, refer to WebLogic Server MBean Data Model.

ActivatedTargets Application | Targets

### ActivatedTargets

List of servers and clusters where this module is currently active. This attribute is valid only for modules deployed via the two phase protocol. Modules deployed with the WLS 6.x deployment protocol do not maintain this attribute. To determine active targets for a module regardless of deployment protocol, use DeployerRuntimeMBean#lookupActiveTargetsForComponent .

For more information, see:

- ApplicationMBean#isTwoPhase

Privileges | Read only
Type | TargetMBean[]
Relationship type: | Reference.

### Application

The application this component is a part of. This is guaranteed to never be null.

Privileges | Read/Write
Type | ApplicationMBean
Relationship type: | Reference.
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server.

### 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.

Privileges | Read/Write
Type | TargetMBean[]
Relationship type: | Reference.

## Attributes

This section describes the following attributes:

DeploymentOrder EJBComponentRuntime ExtraEjbcOptions ExtraRmicOptions ForceGeneration JavaCompiler JavaCompilerPostClassPath JavaCompilerPreClassPath KeepGenerated | Name Notes Parent TmpPath Type URI VerboseEJBDeploymentEnabled

### 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.

### KeepGenerated

indicates whether KeepGenerated is enabled and the ejbc source files will be kept.

Privileges | Read/Write
Type | boolean
Default Value | true

### 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`

Privileges | Read/Write
Type | java.lang.String

### 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 `&lt;`. 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.

Privileges | Read/Write
Type | java.lang.String

### Parent

Return the immediate parent for this MBean

Privileges | Read/Write
Type |

### TmpPath

Return the temporary directory where generated files are stored by ejbc. Deprecated: All EJB compiler output is now stored in the EJBCompilerCache subdirectory of the server staging directory. This directory should not be described as "temporary" since removing it would cause the EJB compiler to be rerun as necessary the next time the server is restarted.

Deprecated.

Privileges | Read/Write
Type | java.lang.String
Default Value | tmp_ejb

### Type

Returns the type of the MBean.

Privileges | Read only
Type | java.lang.String
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server.

### URI

A URI that points to the application module, usually on the Administration Server.

URI can only be set if this is a standalone component; the URI for an application is defined in the application's deployment descriptor.

## Operations

This section describes the following operations:

activated addTarget freezeCurrentValue isSet refreshDDsIfNeeded | removeTarget restoreDefaultValue unSet

### activated

Indicates whether component has been activated on a server

Operation Name | `"activated"`
Parameters | `Object [] { target }` where: `target` is an object of type `weblogic.management.configuration.TargetMBean` that specifies: target
Signature | `String [] { "weblogic.management.configuration.TargetMBean" }`
Returns | `boolean`

### 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"`
Parameters | `Object [] { target }` where: `target` is an object of type `weblogic.management.configuration.TargetMBean` that specifies: The feature to be added to the Target attribute
Signature | `String [] { "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"`
Parameters | `Object [] { attributeName }` where: `attributeName` is an object of type `java.lang.String` that specifies: attributeName
Signature | `String [] { "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"`
Parameters | `Object [] { propertyName }` where: `propertyName` is an object of type `java.lang.String` that specifies: property to check
Signature | `String [] { "java.lang.String" }`
Returns | `boolean`

### refreshDDsIfNeeded

Operation Name | `"refreshDDsIfNeeded"`
Parameters | `Object [] { }` where:
Signature | `String [] { "[Ljava.lang.String;" }`
Returns | `void`

### removeTarget

Removes the value of the addTarget attribute.

For more information, see:

- addTarget

Operation Name | `"removeTarget"`
Parameters | `Object [] { target }` where: `target` is an object of type `weblogic.management.configuration.TargetMBean` that specifies: target
Signature | `String [] { "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"`
Parameters | `Object [] { attributeName }` where: `attributeName` is an object of type `java.lang.String` that specifies: attributeName
Signature | `String [] { "java.lang.String" }`
Returns | `void`
Exceptions | `javax.management.AttributeNotFoundException`

### unSet

Restore the given property to its default value.

Operation Name | `"unSet"`
Parameters | `Object [] { propertyName }` where: `propertyName` is an object of type `java.lang.String` that specifies: property to restore
Signature | `String [] { "java.lang.String" }`
Returns | `void`
