[U2] [UV] LIST.LOCKS - Unable to get process lock semaphore
In addition to my message below, when I enter the UV command LIST.LOCKD I get the following: LIST.LOCKS Unable to get process lock semaphore. [EACCES] Permission denied Unable to get process lock semaphore. [EACCES] Permission denied [192.168.1.1: remote disconnect] Marco Manyevere [EMAIL PROTECTED] wrote: Hi, I get the error message 'Unable to get process lock semaphore' in a complicated application for which I have no source code. 1) What could be the cause of my problem? The only setup parameter I see linked to process semaphores is PSEMNUM which is set to 64. Can I increase this? What unix parameters are related if any? 2) How do I diagnose how many semaphores are actually being used? I'm on Unixware and the system says SEMAPHORE.STATUS is not supported. 3) How can I intentionally cause this problem in my own code? Thanks for any help. Marco. - ALL-NEW Yahoo!

Well would this mean something like I can't access the LOCK table because some other process currently has it LOCKed ? You could try writing a program that sets a lock and see if it also complains with the same message like this OPEN VOC TO F.VOC ELSE STOP READU IGNOREME FROM F.VOC,NOTHING THEN PRINT LOCK SET, RECORD FOUND END ELSE PRINT LOCK SET, NO SUCH RECORD Will --- u2-users mailing list u2-users@listserver.u2ug.org To unsubscribe please visit http://listserver.u2ug.org/

[important bit snipped by Will] [EACCES] Permission denied Well would this mean something like I can't access the LOCK table because some other process currently has it LOCKed ? If the issue were that another process already had control of the resource then the UNIX error would be EAGAIN as in 'try it another time and you might be OK', not EACCES. Try ipcs -s to see what semaphores exist on the system and look at the permissions on those. Perhaps something has caused universe to create the semaphores with a permission mask which stops you doing a semop on them? Perhaps there is a program which is supposed to be setuid to access these things and someone has chmod'ed it and removed the setuid bit? Just my 2 cents. YMMV.
