Monitoring service engine instances
and faults
As an administrator, you may sometimes need to monitor recent instances and
faults of the different components running in the SOA Infrastructure. The execu-
tion status and metrics for an instance in a particular engine can be monitored
from the Oracle Enterprise Manager Fusion Middleware Control console by right-
clicking on
soa-infra
and navigating to
Service Engines
|
[Component]
. Once
you are here, you can see all the recent instances for the selected component
across all the composites.
Examine the following screenshot to see a typical monitoring page for a Business
Rules (Decision Service) engine. The information displayed here includes:
•
Instance ID of the component
•
Component name
•
SOA composite application of which the component is a part
•
State of the instance
•
Instance start time
•
Last modification time
•
A Logs icon
You may also click on other tabs that display the statistics (average processing
times, cache statistics, operation statistics, counts, and so on) or faults, if any,
associated with the service engine. This particular information for the decision
service engine is made available from the
BRDECISIONINSTANCE
table in
the dehydration store. Alternatively, you can also query the database by joining
this
table
and
the
COMPOSITE_INSTANCE
table
on
ECID
or
COMPOSITE_INSTANCE_ID
.
