dtrace discuss - Oct 2007 - -c option in dvm

Hi all,
There is one command in solaris called jmplay which starts java media player.

When I am trying to rum my script as follows:-
dtrace -s ./dvmThread.d -c jmplay

It gives following error.
dtrace: failed to compile script ./dvmThread.d: line 3: probe description
dvm16784:::thread-start does not match any probes

But when I run jmplay separately and then by giving its pid, same script runs
successfully.

Script source is as follows:-
#!/usr/sbin/dtrace -s
#pragma D option quiet
dvm$target:::*
{    
  printf("Probename  :-   %s\n", probename);  
}

Can anyone please tell me what is going wrong?

Thanks,
Ajit

Hi Ajit:

Try the -Z option.

Basically the dvm probes take a little time to initialize. The -Z
will allow you to turn on probes that are yet to be initialized.

Hi Angelo,
thanks for your help.
It works with -Z option.



Thanks,
