Hi,

I'm trying to get Eclipse TPTP to profile an application running on
Weblogic 9.2. Here is the history of what I've done so far:

1> Installed and configured Agent Controller
2> Created test app called "test.jar" and ran it as follows:
java '-agentlib:JPIBootLoader=JPIAgent:server=enabled;CGProf' -jar
/home/support/test.jar
Which works and I'm able to see it in Eclipse to profile.
3> Tried to add the -agentlib switch to Weblogic startup and it fails. Noticed
on newsgroups that I should use -XrunpiAgent. That didn't work either.
4> Tested test.jar the switch -XrunpiAgent and it failed "could not find the
agent library"
5> Ran strace "strace java -XrunpiAgent -jar /home/support/test.jar" which
revealed that the file libpiAgent.so couldn't be found. I've looked in
/usr/lib which from what I gather is it's normal home and it's not there.

My questions are:

Q1 >Does -XrunpiAgent replace -agentlib? if so what are the differences
and what does each do?
Q2> Where can I get libpiAgent.so for SUSE from?
Q3> Given a correctly configured environment should step 4 (above) work?
Q4> Whats the difference between RAServer and ACServer? I'm currently using AC.

Thanks in advance,

Rob

Hi Rob,

You do not have the profiling agent libraries in your system environment
varialble setup for the profiler to be loaded.

Please refer to the following documentation no how and what variables to
setup:
http://www.eclipse.org/tptp/home/downloads/4.5.0/documents/i nstallguide/AgentController45.html

To answer you questions:
1. -XrunpiAgent does not replace -agentlib, they are used for different
JVM. -XrunpiAgent is for JVM 1.4.2 and below while -agentlib is targeted for
JVM 1.5+.
2. The libpiAgent.so should be packaged under the Agent Controller install,
under the plugins folder.
3. you have to make sure the server process picks up the enviornment
varilable setup for the libraries to be loaded successfully.
4. They are actually the same.
