# ActivationTaskMBean

Overview | Related MBeans | Attributes | Operations

## Overview

Provides information about an activation task, which is initiated by invoking the `ConfigurationManagerMBean activate` operation.

To describe the changes that are being activated in the domain, this MBean contains one `Configuration` object for each change that was saved to the domain's pending configuration files.

This MBean also contains attributes that describe the status of the activation operation as it attempts to distribute changes to all servers in the domain.

Factory Methods | No factory methods. Instances of this MBean are created automatically.
Access Points | You can access this MBean from the following MBean attributes:
ConfigurationManagerMBean.ActiveActivationTasks ConfigurationManagerMBean.CompletedActivationTasks |
Access Points Inherited from Service | Because this MBean extends or implements Service, you can also access this MBean by retrieving Services. The following attributes contain Services and its subtypes:

## Attributes

This section describes the following attributes:

Changes CompletionTime Details Error Name ParentService | StartTime State StatusByServer Type User

### Changes

Contains the `Change` objects that describe the changes that are being activated.

Each `Change` object describes a change to a single MBean attribute.

Privileges | Read only
Type | interface weblogic.management.mbeanservers.edit.Change[]
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server.

### CompletionTime

The time at which the activation task completes, either by successfully activating changes on all servers, rolling back all changes (because a server was unable to consume the changes), or by timing out.

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

### Details

Contains all available information about the current activation task in a single `String` object.

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

### Error

Returns the exception that describes why the activation has failed.

To see how each server responded to the activation request, get the value of this MBean's `StatusByServer` attribute.

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

### Name

A unique key that WebLogic Server generates to identify the current instance of this MBean type.

For a singleton, such as `DomainRuntimeServiceMBean`, this key is often just the bean's short class name.

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

### ParentService

The MBean that created the current MBean instance.

In the data model for WebLogic Server MBeans, an MBean that creates another MBean is called a parent. MBeans at the top of the hierarchy have no parents.

Privileges | Read only
Type | weblogic.management.provider.Service
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server.

### StartTime

The time at which the `ConfigurationManagerMBean activate` operation was invoked.

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

### State

The state of the activation task, which is initiated by invoking the `ConfigurationManagerMBean activate` operation.

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

### StatusByServer

The state of the activation task on each server in the domain.

If any server fails to activate the changes, the activation task is rolled back for all servers in the domain.

Privileges | Read only
Type | interface weblogic.management.mbeanservers.edit.ServerStatus[]
Redeploy or Restart required | Changes take effect after you redeploy the module or restart the server.

### Type

The MBean type for this instance. This is useful for MBean types that support multiple intances, such as `ActivationTaskMBean`.

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

### User

The name of the user who invoked the `ConfigurationManagerMBean activate` operation.

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

## Operations

This section describes the following operations:

waitForTaskCompletion waitForTaskCompletion |

### waitForTaskCompletion

Allows the caller to wait until any of the following occurs:

- The activation task completes (either by successfully distributing changes or by rolling back the task)

- The activation task times out

- The number of specified milliseconds elapses

Operation Name | `"waitForTaskCompletion"`
Parameters | `Object [] { timeout }` where: `timeout` is an object of type `java.lang.Long` that specifies: long that specifies the time (milliseconds) to wait for the activate deployment request to complete.
Signature | `String [] { "java.lang.Long" }`
Returns | `void`

### waitForTaskCompletion

Allows the caller to wait until the activation task completes (either by successfully distributing changes or by rolling back the task) or times out.

Operation Name | `"waitForTaskCompletion"`
Parameters | `null`
Signature | `null`
Returns | `void`
