Question

I am trying to debug a program running on a remote solaris machine.
I wanted to know path taken by the program during the execution just like stake trace
like

Class A.method1 called method2 in class B
Class B.method2 called method3 in class C
..
...
Control returned from method2 in class B to
method1 in Class A etc

We cannot run the program from eclipse since the environment cannot be reproduced since it is a large enterprise level system having many upstream and downstream systems.

I suspect somewhere in the program there is an exception being thrown and that is not handled properly like a empty catch block/not logging or rethrowing the exception.

What is the best way to debug such programs. Please help me with your solutions.

Answer 1

Since, your remote machine runs under Solaris you could use DTrace to dynamically add probes to your running JVMs and the complete system.
