10.7 Tuning the Model Snapshot Process
You can tune the model snapshot process through the following parameters, available as JMX MBean attributes:
■
ModelSnapshotMinAbsCorrelation controls whether to snapshot all correlation
rows or to set a minimum correlation value for snapshots.
■
ModelSnapshotNumberOfBins controls the number of bins for model snapshots.

Performance Monitoring
Oracle Real-Time Decisions includes a robust performance monitoring system for observing the behavior of Inline Services. Performance Monitoring parameters are set,
and a snapshot view of some of the common counters can be observed, through Fusion Middleware Control. A chronological view can be obtained by enabling the
performance monitor. Once enabled, a comma-separated value CSV file is produced that can be used to observe behavior over time.
This section contains the following topics:
■
Section 11.1, Setting Performance Monitoring Parameters

Section 11.2, Viewing Common Performance Monitoring Snapshot Values

11.1 Setting Performance Monitoring Parameters
The performance monitoring parameters are set using the SDManagementCluster Members Properties PerformanceMonitoring MBean. You can access this MBean
using Fusion Middleware Control; see Chapter 13, Managing Oracle Real-Time
Decisions for more information.
Table 11–1 describes the properties governing performance monitoring.
Caution: This file grows without limit, and should be enabled only
for active troubleshooting.
Table 11–1 Performance Monitoring Properties
Property Name Description
DSPerfCounterEnabled Enables the writing of DS performance counters. This property
should not be enabled indefinitely, because the file grows without limit.
DSPerfCounterAppend If true, performance data is appended to an existing file, if any,
otherwise any existing file is overwritten when the server restarts.
