Business Activity Monitoring
Oracle Business Activity Monitoring (BAM)
provides the tools for monitoring
key business and performance indicators for business services in an enterprise.
It allows correlating market indicators to actual business processes allowing busi-
ness processes to change quickly or take corrective actions in the ever changing
and dynamic business environment. Oracle BAM provides the necessary tools
and runtime services to create enterprise dashboards that display real-time data
inflow and metrics, and defines rules to send alerts under specified conditions.
Oracle BAM components and architecture
BAM Server is a Java EE application deployed to a standard application server
and its architecture leverages the push-based mechanism (using AJAX) to deliver
high a volume of data changes in business processes to the frontend web
browser in real time. This is also a key differentiator from other reporting solutions
that instead use the pulling approach for fetching data and report rendering. The
architecture of Oracle BAM, with various components involved and message flow
from data gathering applications to reporting service applications, is shown in the
next screenshot.
Business data can be pushed to the BAM
Active Data Cache (ADC)
by a variety
of ways such as having sensors in a business process, using an asynchronous
messaging framework, sending data through a BAM JCA adapter, or even using a
web service interface in its most simplified way. The ADC is a high-performance,
persistent, and memory-based storage system designed to receive continuous
data streams from various data sources.
A
Report Cache
is used to off-load the burden of maintaining changes to active
data snapshot in memory from active data cache. Report Cache opens view sets
and caches the snapshot and data changes before sending them over to the
Re-
port Server
, which then renders static and active reports by applying report defin-
itions to the retrieved dataset for presentation in a browser. The Report Serv-
