Dynamic operations monitor the application server environment
and make optimizations or recommendations that are based on the data that
is observed. To prepare a hosting environment for dynamic operation capabilities,
you must first configure your environment.
About this task
To set up the dynamic operations environment you must create node groups, on demand routers, servers and dynamic
clusters. You can then deploy your applications and define service policies.
The autonomic managers work with these elements to maximize the performance
of your environment.
Procedure
- Create node groups. A node group
contains nodes that have similar capabilities. Use node groups to create a
resource pool of similar functions that can be shared or used for failover
support. Create a node group for your dynamic cluster.
- Create an on demand router (ODR). The on demand router
is a proxy server that can route work to servers. See Creating ODRs
for
more information.
The
ODR cannot run on a node that is in a node group that dynamic clusters use.
- Create dynamic clusters. When in automatic mode, WebSphere Extended Deployment can
automatically control the size and placement of dynamic clusters on the nodes.
In supervised mode, the administrator can review information and suggested
actions that are provided by WebSphere Extended Deployment in the form of runtime
tasks. See Creating dynamic clusters
for more information.
- Optional: If your dynamic clusters
are running in supervised mode, you receive notifications of runtime tasks
that are proposed by the system for changes to the configuration or runtime.
To view and act upon these tasks in the administrative console, click Runtime
operations > Task management > Runtime tasks. You can also configure e-mail
notifications to send to specified users when runtime tasks occur. See Defining e-mail notification
for more information.
Results
You configured the underlying hosting environment
to support dynamic operations. The autonomic managers can use your configuration
to automatically manage your environment.
What to do next
After your environment is prepared for dynamic
operations, you can deploy an enterprise application with defined service
levels.
