JVM exists with error while running sampling activity

michael_rvsn — Wed, 08 Jul 2009 09:24:06 GMT

Hello!

I start running Sampling activity JVM and vtlec exites with error message.
There is no any problem to work with callgraph activities.

The error message is downloaded to error/JVM_terminated.jpg.
What can be wrong with my installation?

Thanks in advance.

Best regards,

Hi Michael,

Since you said there is no problem to do call graph activity, please check -
1. Whether you have installed vtune driver? do "lsmod | grep vtune"
2. Are you using latest v9.1 Update 2?
3. What is your running operation system? Use default JVM version? If youuse other JVM, pleaseensure it is supported in release notes (If youwork onx86_64operation system - please use 32bit JVM).
4. Areyour using sampling activity for Java application?Try samplingactivity in command line
a) export PATH=$PATH:/opt/intel/vtune/bin; cd /opt/intel/vtune/samples/java; make all
b)vtl activity -d 120 -c sampling -o "java" -app "java, gsexample2a datafile.txt" run

Finally try sampling activity on Graphic User Interface.

Regards, Peter

Hi,

Peter thank you for your answer.

The problem happens when we use GUI (vtlec).

1. [root@junos ~]# lsmod | grep vtune
vtune_drv 218940 0
2. [root@junos ~]# uname -a
Linux junos 2.6.9-42.ELsmp #1 SMP Wed Jul 12 23:27:17 EDT 2006 i686 i686 i386 GNU/Linux
We are using VTune 9.1
3. [root@junos ~]# java -version
java version "1.4.2"

Michael, Thanks for detail info.

I don't know if gcj-1.4.2 is supported. However my java version gij is from Red Hat* 4.1.1-52, yours is from Red Hat* 3.4.6-3.

So please try java sampling on standard Linux* distribution.

Hi Peter,

Thank you for your answer.

I checked with your java 1.4.2 and it works!:).
Apparently new java 1.6 has somthing incompatible with my vtune version.

Thank you again

Michael
