Profiling. Can't make it work [message #46967]

Hi,
I'm trying to profile my app with TPTP 4.1, without success so far.
First, I've tried 4.1 as it is, out of the box, with the local direct
connection. It's totally unusable, my apps takes 3 seconds to start
up in normal conditions, with profiling and LDC it takes over a minute.
I've seen in another thread that you suggest installing the RAC instead.
Ok, I've downloaded and installed it, then configured it with the SetConfig.bat
script.
Then I try to start RAServer manually, but nothing happens, it exists
right away, without error messages, and the exit status is 0. Telnetting
on localhost, port 10002 does not lead to any answer, apparently there's nothing
running over there...
I've also tried installing the RAService, but when I net start it, I get
"internal error 112".
I also tried running the profiling agent from command line (PerfMonAgent.exe),
it starts, but then it keeps printing "(No agent monitoring yet (freq:1000ms)"
even when I run the profiler from Eclipse.

Oh my... it was so much easier (and faster) with hProf and HPJMeter,
too bad HPJMeter crashes right away trying to parse the hProf generated file...

Oh, I'm running on JDK 1.5.0_06, Windows 2000, Eclipse 3.1.1, TPTP 4.1.

Anyone can help me?
Best regards
Andrea Aime

Did you add RASERVERPATH/bin to your path?

RAServer shouldn't crash, so if it does, it might be because it can't find
its configuration.

Hi Andrea,

It's unfortunate you're having all this trouble getting started with TPTP.
Please see my responses below:

We're working on improving the performance of LDC and will most likely
release a faster version of it soon as a patched driver.

Follow the steps below:
- Go to the config director of your RAC, open servicelog.log, erase all of
its content
- Try running RAC again using bin\RAServer
- Check servicelog.log file to see if it has any valuable informaiton.
This file is in CBE format and you can import it as a CBE log file using
the Logging tools available in TPTP. In your workbench, right click ->
import -> Log file -> Add -> add the log file by selecting Common Base
Event XML log. You can also put the log file here for one of us to
analyze.

You might also want to try regenerating the serviceconfig.xml file again
using setconfig.bat.

This is not the profiling agent. It's the agent used for monitoring your
system resources. You shouldn't need this for profiling.

I think, I've discovered the cause of your problem. You probably have the
Local Direct Connection up and running when you try to start the RAC. The
Local Direct Connection takes up the named pipe that the RAC uses so you
can't have both of them running at the same time. Follow the instructions
below:

- Exit the workbench
- Kill all the lingering java processes
- Try starting the RAC

Unfortunately we don't output a proper error message for this use case.
I've opened a bug to address the problem:
https://bugs.eclipse.org/bugs/show_bug.cgi?id=121239 feel free to add
yourself to the CC list.

Yes, I think you're right. Today I've powered up the PC, the raservice
started properly and I can now profile with decent speed (althought it's
still slower than using hprof with statistical information gathering).

Thank you for your suggestions :-)
Andrea
