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.
