You can configure additional functions to enhance the autonomic
functions of the application infrastructure virtualization environment.
These functions include maintenance mode, health management, centralized
installation manager, high availability deployment manager, repository
checkpoints, and autonomic managers.
Before you begin
Configure
the on demand router (ODR), servers, dynamic clusters, applications,
and service policies.
About this task
After you set up your basic hosting environment with application
server virtualization, you can tune the behavior of the managers that
make decisions in your environment. You can also configure several
features to help with administration.
Procedure
- Set maintenance mode on your nodes and
servers to perform diagnostic tests, maintenance, or tuning on a node
or server without fear of disrupting incoming traffic to that node
or server in a production environment. See Setting maintenance mode for more information.
- Configure health management. With
health management, the health controller monitors health policies,
which contain conditions to look for in the environment, and actions
to take when these conditions are not met. See Configuring health management for more information.
- Use the centralized installation manager
to shorten the number of steps that are required to create and manage
your environments. See Using the centralized installation manager to set up your environments for more information.
- The high availability (HA) deployment
manager function can be configured to eliminate the deployment manager
as a single point of failure for administrative functions in a Network
Deployment cell. See Configuring a high availability deployment manager environment for more information.
- Configure repository checkpoints to save images of the
repository before configuration changes are made. You can use these
images to restore the configuration repository back to a prior state. See Configuring a checkpoint for more
information.
- You can tune the behavior of the autonomic managers that
make decisions for the environment, including the health controller,
autonomic request flow manager, and the application placement controller. See Configuring the autonomic managers for more
information.
What to do next
Monitor the operations of your environment.
