File open/lock activity in Remote Manager?

Hi,

We recently upgraded from Novell Netware 6.0 to Novell Open Enterprise
Server (OES1 with SLES9) on the Linux kernel (Linux 2.6.5-7.244-smp).
While using Netware I checked for file open/lock activity through
MONITOR.NLM, obviously this tool isn't available for OES1 on Linux.

So I figured this feature would be available in Novell Remote Manager.
Unfortunately it is nowhere to be found. Is this feature not available on
OES1? Or is there some other tool that with this feature? Or am I just
looking in the wrong place?

I really would like to know how I can check which files are being used by
which connection (and by that which user).

If anyone has some information on this topic, it would really help me out.

Thanks in advance.

Tim
