What is truss/trace?

This is HP Tru64 5.1A. Oracle support asked us "can you confirm if you have truss/trace installed on this node as I'd like to further explore which o/s system call is at fault here if related?". However, I don't understand what truss/trace is. Can you explain it? How can I check whether we have installed it on this node?

Thanks

Eric

Re: What is truss/trace?

Truss and trace are utilities you can use the trace the system calls of a running process. truss is delivered with the Extended System V features in the Associated Products CD (I think # 2) on V5 and later (it doesn't require an additional license).

trace is open source. It could be on the freeware CD.
