oracle.toplink.tools.profiler
Class DMSPerformanceProfiler

java.lang.Object
  oracle.toplink.tools.profiler.DMSPerformanceProfiler

All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, SessionProfiler

public class DMSPerformanceProfiler
extends java.lang.Object
implements java.io.Serializable, java.lang.Cloneable, SessionProfiler

Purpose: Define the interface of TopLink profiler for using DMS gate.

Description: A mechanism used to provide a link for TopLink performance profiling by using the DMS tool. The predefined TopLink metrics will be monitored by using DMS sensors. TopLink library instrumentation will be done by inserting DMS calls for the purpose of measuring its performance

Responsibilities:

• Define the TopLink metrics.
• Provide APIs to monitor the sensors at runtime.
• Change DMS sensor weight at runtime

Since:

TopLink 10.1.3
