■
Gross Throughput reqsec: The average rate of requests finishing during the
current logging interval, in requests per second. The formula is: RequestsFinished SnapshotPeriod 1000
■
Net Throughput reqsec: The average rate of requests finishing during the
current logging interval, excluding requests that timed out. The formula is: RequestsFinished - Timeouts SnapshotPeriod 1000
■
Utilization : The percentage of the servers capacity utilized during the current
logging interval. The formula is: RunTimeAverage RequestsFinished MaxAllowableRunningRequests
SnapshotPeriod 100 This value can be briefly larger than 100 when requests are finishing that started
running in previous logging intervals.
11.5 Switching Off Authentication and Authorization
By default, Oracle RTD has authentication and authorization switched on. In order to improve performance in Decision Server, you can switch off authorization and
authentication.
For Oracle RTD Decision Server authorization to be switched off, perform the following steps:
1.
Log in to Fusion Middleware Control, as described in Section 2.1.1, Logging into
Fusion Middleware Control.
2.
In the Target Navigation Pane, under Application Deployments, right-click the OracleRTD server entry, then select System MBean Browser.
3.
In the System MBean Browser, scroll down to the Application Defined MBeans, select OracleRTD and then the server name where Oracle RTD is deployed.
4.
Select SDClusterPropertyManager, then Cluster.
5.
Set RequireIntegrationPointAuthorization to false. You can switch off Decision Server authentication on a web service. For details, see
Web Service Security in Oracle Fusion Middleware Platform Developers Guide for Oracle Real-Time Decisions.

Backup and Recovery of Oracle Real-Time Decisions
Backup and recovery refers to the various strategies and procedures involved in guarding against hardware failures and data loss, and reconstructing data should loss
occur.
Backup and recovery for Oracle Real-Time Decisions is fully described in the Fusion Middleware Administrators Guide. For more information, see Oracle Fusion
Middleware Administrators Guide.

Managing Oracle Real-Time Decisions
Oracle RTD uses the J2EE industry standard Java Management Extensions JMX to configure and monitor the operation of Oracle RTD.
Oracle RTD systems deployed into WebLogic are managed using the Fusion Middleware Control MBean Browsers in Enterprise Manager.
JMX MBeans manage various aspects of Oracle RTD, including logging and Inline Service configuration. They can also be used to assign Oracle RTD specific permissions
to security roles and users. Security roles and users are both managed by the J2EE container.
Oracle RTD is comprised of three Services:
■
Decision Center Service: Supports the deployment of Inline Services by Decision
Studio. It also provides a web interface, Decision Center, for displaying the structure and decisioning history of Inline Services.
■
Decision Service: Runs Inline Services and integrates to enterprise operational
processes.
■
Learning Service: Maintains analytic, self-learning models that underlie Inline
Services. Deployments of Oracle RTD are often done across multiple servers as well as in
clusters to enhance performance in high transaction environments. A relational database is used by each of these Services for retention of code, transactional data and
configurations.

Note: Some of the management properties can also be set as system
properties. For details, see Section 13.9, System Properties.
Note: This chapter deals mainly with the management of Oracle
RTD through JMX MBeans in Enterprise Manager. Administrators can also perform certain Inline Service related administrative tasks using
web service calls in their own application utilities. For more information, see the section Administration Web Service in Oracle
Fusion Middleware Platform Developers Guide for Oracle Real-Time Decisions.
