Hi Pando,

Idetifying the status of the nflock kernel parameter, or identifying the status of one lock file?

If you are trying to identify the status of one lock file, use lsof to identify the processid, and run tusc/truss (-p pid) to track down the status.

Hope this helps a bit,

I am not sure what you are refering to.

If you want to know what process is using ( locking ) a file, you may use the fuser command.

Hi Pando,

Are you asking how to tell which files on an HP-UX system are currently locked? If not, please clarify exactly what you're trying to determine.

Thanks,

Dave

Hello Dave and Ignacio,

Sorry for the confusion. Im asking which files on an HP-UX system are currently locked and how to determine the exact numbers that are locked including its file size.

Thanks,
