Encountered error msg while invoking jvmtop

[GoogleCodeExporter]

Hi team,
We encountered error msg as could not attach to process while trying to invoke 
jvmtop with pid.

What steps will reproduce the problem?
1.Execute the command ./jvmtop.sh <pid>
2.we ensured whether the process is running.

What is the expected output? What do you see instead?
Expected output list of top java threads but what we got is listed below
JvmTop 0.8.0 alpha - 10:53:13,  amd64, 24 cpus, Linux 2.6.18-23, load avg 4.26

While we tried with jvmtop without pid we got the below error

Hi,

thanks for the bug report.

Two questions:

1. Are the to-be-monitored processes running with the same JDK as jvmtop is 
running?
2. Are you able to connect to the process, which jvmtop with the JDK tools 
jstack and jconsole?

Hi Patric,

Thanks for the response.

Have listed my answers for your queries

1. Are the to-be-monitored processes running with the same JDK as jvmtop is 
running?
No we don't use jdk for the to-be-monitored processes rather we use IBM jre 1.6
2. Are you able to connect to the process, which jvmtop with the JDK tools 
jstack and jconsole? 
Yes we were able to connect to the process using jconsole and visualvm through 
jmx

Please review and let me know for further details.

Thanks
sattish.

Hi Sattish,

Ok, thanks you for your update!
Some more questions:

1.  Could you please execute the following two commands and tell me there are 
referring to the same directory/JDK?
type java
type jconsole

2. can you try setting the JAVA_HOME environment variable to the JDK from which 
your IBM jre 1.6 is part of and try to execute jvmtop and see if there's any 
difference?

3. If not, please run jvmtop with the following arguments:
jvmtop.sh --once --verbose

If there any exceptions are displayed, please post them here.

Cheers,
- Patric
