YourKit Java Profiler¶

Profile the cdmserver (cdmlib-remote-webapp)¶

Preparation:

To enable profiling on remote server you just need to copy appropriate libyjpagent.so and, put it into LD_LIBRARY_PATH and add "-agentlib:yjpagent" to JVM parameters. Most probable you copied wrong library file, that's why server JVM doesn't start.

see also http://www.yourkit.com/docs/java/help/agent.jsp

Run cdmlib-remote-webapp in profiling mode:

Use the launch configuration cdmserver - profile which is distributed via the cdmlib source control.

TPTP¶

_Using TPTP is discouraged, we rather recommend using the YourKit Java Profiler

in Eclipse by using TPTP.

• Install TPTP as eclipse plugin using Eclipse update site Help -> Software updates -> Find and Install -> Search for new features to install -> check Europa Discovery Site" -> TPTP and select required or check "TPTP

• Download and extract "Agent Controller" from http://www.eclipse.org/tptp/home/downloads/

• execute bin\SetConfig.bat in extracted package. Set path to Java 1.5 (for cdmlib projects ?).

• execute bin\RAServer.exe to start the Agent

• start profiling from within eclipse ...
