Use these instructions to configure the behavior of the autonomic
managers in WebSphere® Virtual Enterprise.
About this task
Configure autonomic managers after your have prepared your environment
to support autonomic management, and if you want to maximize utilization using
your defined business goals. These autonomic managers monitor performance
metrics, analyze the monitored data, offer a plan for running actions, and
can start these actions in response to the flow of work. The following autonomic
managers all work in or with the WebSphere Virtual Enterprise environment.
Procedure
- Configuring the autonomic request flow manager
The autonomic
request flow manager (ARFM) controls the order, timing, and rate of the dispatch
of requests into the application server tier by using classification and the
defined service policy goals. ARFM also can optionally exert admission control
for CPU overload protection. The autonomic request flow manager applies to
HTTP, Session Initiation Protocol (SIP), Internet
Inter-ORB Protocol (IIOP), and Java™ Message Service (JMS) protocols. For
the JMS protocol, the ARFM applies to traffic for message-driven beans only.
- Configuring dynamic application placement
You can configure
the dynamic application placement controller. Dynamic application placement
occurs when the dynamic operations components of WebSphere Virtual Enterprise work
together to start and stop application instances to meet the fluctuating demand
of work requests of varying service policy definitions
- Optimizing the database tier for performance monitoring
Optimize the database tier. The database tier optimization component
extends the monitoring of WebSphere Virtual Enterprise to
detect bottlenecks at the database tier in multi-tier enterprise applications.
- Configuring the health controller
You can configure the health controller, which works to enforce your
defined health policies by monitoring the state of servers and comparing the
data to your defined health policies. When the data meets or exceeds a condition
that is defined in one of your health policies, the health management subsystem
takes action.
