File lock status

,
i have been trying to find/write a script that could do the following:

check a file lock: (file is locked and can't be edited)
if file is locked -> find the process(es) that is using/locking the file->print the list of processes to a log file.
if the file is not locked -> do nothing...

i found this module File::TinyLock http://search.cpan.org/src/JKISTER/File-TinyLock-0.11/TinyLock.pm and has 3 subroutines(lock, unlock, and check) but it seems that it will only work for unix since it uses cmd "ps -p" ... i am trying to modify it to use "tasklist" which works for windows 2003, but no luck so far...

the reason i need this, is because sometimes our deployment fails because a file is locked for more than 10 mins ... it happens on random intervals ( every month or other month/week... ) and it is always random file which gets locked... so my idea is to monitor a file for 24 hours or more to just find a list of applications which lock our files, and from there i can guess which process that is causing this issue, and i might be able to plan the deployment around that...
there are few tools to find what is locking a file, like wholockme and whoslocking, but those are good to use manually since they send the output to a graphic window... i need a script that can write to a log...

while i am working on this Smiley Happy

i hope that somebody on here already has something that i can use Smiley Happy

or maybe more ideas.

this is for windows 2003/

Have you tried "iwfilestate" this would do what you want to acheive, though only thing which you would not be getting is, which process has put the lock on the file.

That's doubtful. He's asking about *OD Target* locking, in most cases that does not have TS installed.

Windows 2003 Resource Kit Tools has oh.exe (Stands for 'open handles'). If you can install it (or convince your Administrators that you need it) it will help.
