Hello, I have googled everything I can think of, but haven't found any documentation for using DLM as a developer. Would someone please point me at a tutorial of some kind? Background: My employer has recently (last week) set up a GFS cluster for evaluation. I am trying to set up a locking test that mimics a system that we use on VMS. Thanks, -Jason -- Jason L.
