A runtime task is generated by a runtime component within
the product. Runtime tasks provide information from which you can
accept, deny or close the recommended action plan.

About this task
Use runtime tasks to view and manage the recommendations
that the autonomic controllers are providing to improve the health
and performance of your environment. If you are running in supervised
mode, you must accept, deny, or close each runtime task. In automatic
mode, the autonomic controllers automatically take these actions.
A
task is lost when it is sent from a node when the deployment manager
is not running. The same holds true in a high availability deployment
manager environment. Even though the down time is minimal between
the time when an active highly available deployment manager shuts
down and when the standby deployment manager becomes active, tasks
are still lost. After a failover of a highly available deployment
manager occurs, the executing tasks at the original active deployment
manager are changed to the unknown state.
Procedure
- From the administrative console, click .
- Click the task ID link to view the task target objects
and corresponding monitors of a specific task. A task target
object is a server, cluster, service policy, node, health policy,
or application. One of these objects might be linked to configuration,
performance or log monitor views in the administrative console.
With a configuration monitor, the placement controller
might recommend that an instance of the TestCluster dynamic
cluster start on the test4 node. The recommendation
states that this action is required for the dynamic cluster to meet
its configured minimum number of running instances. You can click
the link to the configuration panel for the TestCluster dynamic
cluster to view its settings and verify or change the minimum number
of running cluster instances.
For a performance
monitor, you can click a link to a chart with data that is specified
in the monitor and specific to the target object. For a log monitor,
you can click the Runtime tab of the target
object Java virtual machine
logs to investigate the displayed logs.
- To view the action plan for the task, click the task ID.
- To act on a specific task, select the corresponding task,
and from the action list select Accept, Deny or Close. Accepting the task commits the previewed action plan. Closing
the task means that the task is successfully handled by the task management
service or is manually closed. Denying the task places the task in
inactive status if the task is not submitted again in the next batch
of task submissions by the originating component. You can also select
multiple tasks with the same actions. After you act on a task, the
action list is unavailable for that task.
- Click Submit.
Results
The
Runtime tasks panel refreshes,
and performs the actions that you selected to perform on each task.
