After carefully reviewing this conference I have not found an answer to my
question.
I am new to TPTP but am a long time eclipse user.
I followed the tutorial directions for profiling the Product Sample example
and it worked correctly.
I have some confusion over how to use the Integrated Agent Controller to
profile an application
running on my local machine outside of Eclipse.
I am now attempting to profile a J2EE application running on Weblogic 8.1.
The application is built using
ANT and is deployed as an EAR file.
I am attempting to follow one of the tutorials the deal with attaching to
remote/local processes.
My env.
Windows XP SP1
Eclipse 3.1.2
TPTP 4.1.0
Weblogic 8.1
JRE 1.4.2_04
Within eclipse I created a server:
Generic BEA Weblogic Server v8.1
localhost
To the java command to start weblogic I added this based on some of the
things I read here.
-XrunpiAgent:server=enabled
However weblogic would not start with this added.
If I start weblogic without this and I go to the Profile and Logging view
the Run->Profiles and select
Attach - Java Process - New
I get the configuration dialog. Selecting LocalDirect Connection -- Test
Connection works however
on the Agents tab there is an error indicator, there are no agents listed
and the at the top of the dialog
I see the error message;
IWAT0225E You must select at least one agent to attach to.
I had expected to see something from the weblogic service similar to what
the tutorial showed me, however
the tutorial was with Tomcat and not wweb logic. It showed a PID: 1208
Has anyone out there attempted to connect ot a running weblogic system?
Also does anyone know why I do not see any Agents?

Hi,
Yes, the "piAgent.dll" does depends on the following DLL's
- hcclco.dll
- hccldt.dll
- hccls.dll
- hcbnd.dll
- hcclsm.dll
Usually these DLL's are packaged under the same directory as
"piAgent.dll" and should also be in the PATH in order to allow the JVM
to load the profiling agent.

I'm trying to do the same thing but find it all very confusing. In
particular, I have set up the path as outlined below and run weblogic with
the -XrunpiAgent:server=enabled option but the weblogic server doesn't
start up - the java process is created and just sits there, no output is
sent to the console.
OK, thought I, maybe its waiting for me to attach the profiler to it, so I
followed the directions in the 'attach to java process' section of the
TPTP documentation and I selected 'Start monitoring' from the popup menu
in the profiling view. But no, still no sign of life from weblogic and
there are no execution statistics to be had.
So does anyone have any pointers?
BTW1 - where is -XrunpiAgent:server=enabled documented?
BTW2 - if I don't set the path up properly weblogic runs fine, but I
obviously can't attach to it.

Hi Harry,
Let me explain a few things that will hopefully help you in your
confusion. Integrated Agent Controller (IAC) is a replacement for the
Remote Agent Controller (RAC) in the local scenario. RAC allows the user
to profile locally as well as remotely via socket communication. However,
it doesn't make a lot of sense to be running a separate process and
communicating via sockets when you want to profile something locally.
That's where IAC comes in the picture. IAC allows the user to profile
locally without requiring the RAC. The IAC plugin is included in the TPTP
plugin (i.e. tptp.runtime-TPTP-4.1.0.zip). If you're planning to use IAC
for local profiling, then you don't need the RAC and you shouldn't bother
downloading it. The second zip you extracted is the RAC (i.e.
tptp.win_ia32-TPTP-4.1.0.zip).
Now as Samson mentioned, you'll need the IAC DLL files in your PATH before
you can attach to a profiling agent. These would be located in <eclipse
home>/plugins/org.eclipse.hyades.execution_<version>/os/win32/x86
Once you do this, you can start any Java process in 'enabled' mode and
attach to it in the workbench. And it seems like you've already figured
this out by doing (-XrunpiAgent:server=enabled). Now, I have no idea why
Weblogic halts when you add this new VM argument. It shouldn't and I've
never experienced this with any other Java application. This *could* be a
problem with Weblogic.
BTW, You can ignore the Agent Controller is not active: will wait in a
1000 ms loop. message when you're planning to attach to your agent with
IAC.
Now you can also try profiling with RAC instead of IAC to see if it solves
your problem. You shouldn't extract the RAC zip file (i.e.
tptp.win_ia32-TPTP-4.1.0.zip) in your eclipse directory. This isn't an
eclipse plugin. Extract it to some where else on your filesystem. Once
you do that, read the getting_started.html in it to figure out how you can
set it up and start it. You'll need to remove the <eclipse
home>/plugins/org.eclipse.hyades.execution_<version>/os/win32/x86
directory from your PATH and add <RAC_HOME>/bin instead. Then start your
RAC, start weblogic in 'enabled' mode, and try to attach to it in the
workbench. Let me know what happens.

My weblogic was hanging, but it was because of the setup we had to allow

to successfully profile weblogic 8.1.
<!-- Debug -- comment out to allow profiling
<jvmarg value="-Xdebug"/>
<jvmarg value="-Xnoagent"/>
<jvmarg
value="-Xrunjdwp:transport=dt_socket,server=y,suspend=n"/>
<sysproperty key="java.compiler" value="NONE" />
-->
<!-- turn on TPTP profiling support -->
<jvmarg value="-XrunpiAgent:server=enabled" />
I am using the ACServer agent and connecting as documented in the TPTP
docs.
