Dynamic operations monitor the middleware server environment
and can make recommendations or changes based on the data that is
observed. To prepare the hosting
environment for dynamic operations, you must federate middleware nodes,
create the on demand router, create middleware servers and dynamic
clusters, and deploy applications to your servers and dynamic clusters
with an associated service policy.
Before you begin
. Complete the following prerequisite tasks:
About this task
To set up the dynamic operations environment you must create on demand routers, servers
and dynamic clusters. These actions set up the application server
virtualization portion. You can then deploy your applications and
define service policies, which configures application virtualization.
The autonomic managers work with these elements to maximize the performance
of your environment.
Procedure
- Federating middleware nodes
If the node was not federated into the cell during the middleware
agent installation, you can federate the nodes from the command line.
- Creating ODRs
The
on demand router is a proxy server that can route work to servers.
- Adding middleware servers to configurations
Middleware servers include any servers in your middleware
tier that provide the infrastructure for your applications or data.
- Creating dynamic clusters
You can associate any representations
of external middleware servers with dynamic clusters. Creating
a dynamic cluster enables application server virtualization. When
in automatic mode, WebSphere® Virtual
Enterprise 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 Virtual
Enterprise in the form of runtime
tasks.
- Deploying applications with defined service levels
You can also enable
application virtualization. The steps to deploy applications vary
depending on the type of servers that you are using. You can deploy
enterprise applications, PHP Hypertext Preprocessor (PHP) applications,
unmanaged Web applications, or WebSphere Application
Server
Community Edition applications..
- Defining a service policy
Associate your middleware
applications with service policies, work classes, and routing policies
to enhance performance and resiliency.
- Start stand-alone servers,
and place your dynamic clusters into automatic or supervised modes.
Results
The on demand router can route requests to applications that
are deployed on your servers and dynamic clusters according to your
defined service policies, work classes, and routing policies. These
steps have configured application infrastructure virtualization in
your environment.
What to do next
After you have your
dynamic operations environment configured, you can use various features
that depend on this environment to further enhance your operations.
These features include health management, centralized installation
manager, application editions, and more.
