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
For your convenience you can use the following script to start eclipse and set the LD_LIBRARY_PATH:
#!/bin/bash ########################################### # Configuration # ECLIPSE_FOLDER=~/opt/eclipse-juno-SR2 YOURKIT_FOLDER=~/opt/yjp-10.0.6 OS_TYPE="linux-x86-64" # ########################################### export LD_LIBRARY_PATH=${LD_LIBRARY_PATH}:${YOURKIT_FOLDER}/bin/${OS_TYPE} $ECLIPSE_FOLDER/eclipse -vmargs -Duser.name="a.kohlbecker"
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 ...
