how to check if a dataset is used either by a process or a person

[alepage]

Hello,

A colleague of mine is using a sas program to update a particular dataset.  But when the dataset is already used by either another process or user, we get the error message lock.  

Is there a way to check if the dataset to be updated is free before updating it and if not how can we "liberate this file"

On a UNIX (Linux) system, you can remove the file before writing the dataset.

Also on UNIX, the fuser command can be used to display the process(es) having an open file handle on a particular file.

if we find that a process have an open file handle on a particular one, is there a way to liberate this file using a unix command and if so how to do that
