Managing Performance Tuning and Query Caching
This chapter provides information about ways to improve Oracle
Business Intelligence query performance,including a performance
tuning overview and information about monitoring system metrics. It
also describesthe how to manage and use the query cache, a feature
that enables the Oracle BI Server to save the resultsof a query in
cache files and then reuse those results later when a similar query
is requested. Using cache,the cost of database processing must be
paid only once for a query, not every time the query is run.
1. Monitoring Service Levels1.1.Using Fusion Middleware Control
to View Common Performance Metrics
You can access the most commonly viewed performance metrics from
the Metrics tab of the CapacityManagement page.
To use Fusion Middleware Control to view common performance
metrics:
Go to the Business Intelligence Overview page, as described in
Section 2.2.3, "Using Fusion MiddlewareControl to Manage Oracle
Business Intelligence System Components."
Display the Metrics tab of the Capacity Management page.
On the Metrics tab, you can view metrics that are related to
responsiveness, load, and reliability. Click the
Help button on the page to access the page-level help for the
following metrics:
Request Processing Time (ms)
SOA Request Processing Time (ms)
Average Query Time (seconds)
Active Sessions
Requests (per minute)
SOA Requests (per minute)
Presentation Services Requests (per second)
Server Queries (per second)
Failed Queries
Errors Reported (in the last hour)The metrics that are displayed
on this tab enable you to determine the current responsiveness,
load, and
reliability for Oracle Business Intelligence components across
the entire cluster.
1.2 Using Fusion Middleware Control to View All Oracle Business
IntelligenceMetrics
You can view and graph all the available Oracle Business
Intelligence metrics from the PerformanceSummary page in Fusion
Middleware Control. The data is logged transiently (that is,
logging starts when you
go to the page and select a particular metric for display).
To use Fusion Middleware Control to view all performance metrics
for Oracle Business Intelligence:
In the tree navigator, expand the Business Intelligence folder
and right-click the coreapplication node.
Select Monitoring, and then select Performance. The Performance
Summary page appears, displaying a
selection of metrics for this Oracle Business Intelligence
installation.
Note:
Alternatively, to view the Performance Summary page, you can go
to the Metrics page of the CapacityManagement tab and click View
the full set of system metrics.
To customize the metrics that are displayed on the Performance
Summary page, click Show Metric Palette.Then, expand the
appropriate metric category and select or deselect individual
metrics. The metrics that youselect are displayed on the
Performance Summary page.
For information about a particular metric, right-click the
metric and select Help.

1.3 Using the Administration Console to View Metrics for Java
Components
Use the Administration Console to view metrics for Java
components. You can view metrics on theMonitoring tab for the
selected Managed Server, or you can use the Metric Browser. If your
deployment is
based on the Simple Install type, use the Monitoring tab for the
Administration Server.
To view metrics for Oracle Business Intelligence in the
Monitoring tab:
Log in to the Administration Console.Expand the Environment node
in the Domain Structure window.
Click Servers. The Summary of Servers page is displayed.
Click the server name (for example, oracle_bi1 or
AdminServer(admin)).
Click the Monitoring tab.
Click Help for more information about the metrics displayed on
this tab.
To access the Administration Console Metric Browser:
Log in to the Administration Console.
Click Monitoring Dashboard under Charts and Graphs.
Click the Metric Browser tab.
Click Help for more information about using the Metric
Browser.
