Description
Aubrey Barnard
I can also reproduce a similar problem on a downstream product of TPTP. Can you point me to the Popescu tutorial? It might be outdated. Did you set the PATH and LD_LIBRARY_PATH? The Popescu tutorial can be found here: http://www.eclipse.org/articles/Article-TPTP-Profiling-Tool/tptpProfilingArticle.html Or you can get to it by going to the front page (http://www.eclipse.org/tptp/), clicking the "Articles & Tutorials" link in the "Discover TPTP" box on the upper right. On the resulting page the Popescu tutorial is the third entry in the first section ("Articles about TPTP") entitled "Java Application Profiling using TPTP (Eclipse corner) by Valentina Popescu", February 2006. I think that the tutorial is a bit outdated. However, I didn't follow it very closely. Therefore, it is likely more of a distraction than a help. I am working on writing a set of reproducible steps for the problem which will be a better starting point. I did not set either of the paths you mentioned because the documentation (http://www.eclipse.org/tptp/home/downloads/4.5.0/documents/installguide/InstallGuide45.html, http://dev.eclipse.org/viewcvs/index.cgi/platform/org.eclipse.tptp.platform.agentcontroller/src-native-new/packaging_md/linux/getting_started.html?root=TPTP_Project&view=co) says that you don't need to do anything to get the Integrated Agent Controller to work. Furthermore, I still have problems when setting PATH and LD_LIBRARY_PATH to point to the agent controller installed in <eclipse-base>/plugins/org.eclipse.tptp.platform.ac.<...>/agent_controller/{bin|lib}. I think it is more than just a path issue. The following error is seen when profile in a downstream product on Linux RHEL5 32bit machine, with latest TPTP 4.5.1 build. (0801) JVMJ9TI001E Agent library JPIBootLoader could not be opened (libJPIBootLoader.so: cannot open shared object file: No such file or directory) JVMJ9VM015W Initialization error for library j9jvmti23(-3): JVMJ9VM009E J9VMDllMain failed Could not create the Java virtual machine.

WRT 4.5.1 probloem, Joel tells me that JVMTI profiling was broken on Linux until 08-06 build. Aubrey, would you please see if the 08/06 driver (or later) fixes the problem you are seeing? On RHEL5.0 32 bit machine with 0806 all-in-one 4.5.1 build, I can reproduce the same problem. In the 0806 all-in-one build, I get FATAL ERROR: JPIAgent can't load ACCollector for JVMTI agent standalone use case, and JVMJ9VM011W Unable to load piAgent: libpiAgent.so: cannot open shared object file: No such file or direcory for JVMPI agent standalone use case.

These errors were most likely caused by 243213. 0807 build should contains the fix which should be available soon. I've tried to reproduce the original problem in a variety of setups. However, I now encounter bug 243784 and cannot reproduce the original problem. So, for the time being, I only see in the original problem in my development environment, which is unsuitable for detailed investigation. Any suggestions? 0809 build should contains the fix for 243213. The only problem so far with that build is IAC can't be started but stand-alone AC should work. Download from http://www.eclipse.org/tptp/home/downloads/?buildId=TPTP-4.5.1-200808090100. Aubrey, can you try 0812 build and see if IAC works for you? Aubrey, any luck with IAC? This is marked as a blocker and may impact TPTP 4.5.1 release. Bing, I had someone try to reproduce with the 20080813_1936 driver. Here are the results... couldn't get the same error as before, but this time profiling a server got timed out, the workspace log file is as follows: !SESSION 2008-08-14 16:42:35.908 ----------------------------------------------- eclipse.buildId=unknown java.fullversion=J2RE 1.6.0 IBM J9 2.4 Linux x86-32 jvmxi3260-20080806_21795 (JIT enabled, AOT enabled) J9VM - 20080806_021795_lHdSMr JIT - r9_20080721_1330ifx2 GC - 20080724_AA BootLoader constants: OS=linux, ARCH=x86, WS=gtk, NL=en_US Command-line arguments: -os linux -ws gtk -arch x86 -clean !ENTRY org.eclipse.wst.common.project.facet.core 4 0 2008-08-14 16:48:54.960 !MESSAGE Project facet jsf.base has not been defined.

Workspace log for failing IAC
I tried the 200808150100 All-In-One build just now. No success. There appear to be an improvement, however.
Steps:
1. Unzip the All-In-One distribution.
2. Run Eclipse.
3. Create Java project.
4. Create Java class with main.
5. Profile as application.
6. Launch configuration dialog comes up with the Monitors tab showing.
7. Tries to find monitors, but fails with:
"IWAT0435E An error occured [sic] when connecting to the host."
shown in red above where the list of monitors would be.
8. The improvement (?) is that the progress for "Fetching children o...ector:" increases until about 50% and then the message goes away, rather than hanging at 0%.
The log in the workspace lists many problems. I have attached the whole thing since I don't know what snippet would be relevant.
Looks like the same problem as bug 240677. The library that needs to be installed to fix the problem is listed in comment #7 of that bug, and can be installed through the standard RHEL package GUI. Bing, please confirm this is caused by 240677 so we can close the defect. Hi Aubrey, +++++++++++++++++ ENTRY org.eclipse.tptp.platform.iac.administrator 4 0 2008-08-15 12:58:53.930 !MESSAGE RAServer generated the following output: [Error Stream]:ACServer: error while loading shared libraries: libstdc++-libc6.2-2.so.3: cannot open shared object file: No such file or directory ++++++++++++++++ From these errors in your log file, we think it's the same problem that causes 240667. 240667 has been retargeted to 4.5.2 release. If you want to fix the problem before that, on RHEL5, the following package can be installed: compat-libstdc++-296 - 2.96-138.i386.rpm. *** This bug has been marked as a duplicate of bug 240667 *** Bing, you've made a typo and connected this bug to bug 240667 instead of bug 240677. (I noticed since you added me to the CC list on bug 240667, which seems to have no relevance to this bug.) *** This bug has been marked as a duplicate of bug 240677 *** I had our system administrator install the library in question, and I no longer see errors regarding the library. However, the IAC still does not work. The log is not all that helpful. Here is the relevant part from the end of the log: !ENTRY org.eclipse.tptp.platform.iac.administrator 4 0 2008-08-18 15:08:01.283 !MESSAGE RAServer generated the following output: [Output Stream]:Creating default Agent Controller configuration file. !ENTRY org.eclipse.tptp.platform.iac.administrator 4 0 2008-08-18 15:08:01.284 !MESSAGE RAServer generated the following output: [Output Stream]:Security is turned off. Access is set to Local. !ENTRY org.eclipse.tptp.platform.iac.administrator 4 0 2008-08-18 15:08:01.284 !MESSAGE RAServer generated the following output: [Output Stream]:Run the SetConfig script to change the default settings. !ENTRY org.eclipse.tptp.platform.iac.administrator 4 0 2008-08-18 15:08:02.562 !MESSAGE RAServer generated the following output: [Output Stream]:Error reading the Agent Controller configuration file. Please check for valid configuration.Could not start Agent Controller. The last 3 messages repeat 4 more times. On the GUI, the symptoms are the same as those I mentioned in comment 16. In my opinion, this bug should be reopened. A problem still exists that is different than that of bug 240677. (Note: I used build 200808150100 to investigate this.) Aubrey, can you attach your serviceconfig.xml? Are you invoking IAC from Eclipse workbench? Can you describe how to reproduce your error, including <install dir> and <workspace dir>? I apologize for making a mistake in comment 22. I was sure I was using the 200808150100 build when I wrote comment 22, but after investigating your questions, I realized I must have been using the 200808090100 build. (An oversight in my automated test setup.) In the 200808150100 build, the IAC works for me. If you still want me to provide additional information, I would be glad to do so. Thanks Aubrey. Just be aware that IAC stil has some issue (244265 and 243214) which should be fixed very soon. Closing now. Reopen if appears again. As of TPTP 4.6.0, TPTP is in maintenance mode and focusing on improving quality by resolving relevant enhancements/defects and increasing test coverage through test creation, automation, Build Verification Tests (BVTs), and expanded run-time execution. As part of the TPTP Bugzilla housecleaning process (see http://wiki.eclipse.org/Bugzilla_Housecleaning_Processes), this enhancement/defect is verified/closed by the Project Lead since this enhancement/defect has been resolved and unverified for more than 1 year and considered to be fixed. If this enhancement/defect is still unresolved and reproducible in the latest TPTP release (http://www.eclipse.org/tptp/home/downloads/), please re-open. |
