Calling for system-calls guru

[fmarchioni]

Hi all java users,
I'm interested to inspect the memory of my Solaris box when a Java
application is running.
I have read that -T <syscall> option of truss command stops the process
when a syscall is made.
Now the point is: which is the syscall issued when a Java method is
called ?
Can anybody give me an advice about it ?

Thanks a lot
Francesco

No syscalls are involved when Java methods are invoked. If you want to
monitor the memory of your system, there are Solaris tools like
vmstat, top, or pmem for that. You haven't specified exactly what you
are trying to find, so it's hard to be more specific.

This may help:

This sounds like it might be more of an OS issue than a Java issue, so
xyou might have a look in comp.unix.solaris.

Hi Gordon
Thanks for your reply.
Actually I'm behind memory leaks. I'd like to monitor the memory
used by a Java application (with Solaris administration tools)
at a certain point. For example when a method is called or a
constructor is invoked.
I know that there are already some graphical tools that do this but
I'm more affectioned to the shell then to graphical tools.
