I have a situation that needs Oplocks too, and have been corresponding with several of the Samba team on this - Andrew Tridgell and Jeremy Allison to be specific. As of last week, initial OPLOCK support was in place, and they were ironing out some bugs. Jeremy told me that a public Samba alpha/beta release with oplock support would most likely show up on the Samba ftp site this week or next. I would imagine it will be "1.9.18alpha1" or something like that. I would not use an alpha release of Samba in your production environment, but I would take heart - it appears that your performance issues with Samba will be solved in the very near future - if your users can wait a month or two...

Hi All,
I don't seem to be able to subscrube to the samba list because I am on
ht esamba-ntdom list, so can you please respond directly to me.
I have put up a share for the accounting people where tey store the
quickbooks files. When one person accesses the file everything is
fine. smbstatus looks like this:
Locked files:
Pid DenyMode R/W Oplock Name
--------------------------------------------------
2216 DENY_NONE RDWR EXCLUSIVE+BATCH
/usr1/oracom/accounting/Quickbooks 2000/Active/New QB.QBI Tue Sep 12
13:03:07 2000
2216 DENY_NONE RDWR EXCLUSIVE+BATCH
/usr1/oracom/accounting/Quickbooks 2000/Active/New QB.QBW Tue Sep 12
13:03:06 2000
notice the Quickbooks stuff has the exclusive+batch oplock. Now when
someone else tries to access the file (which is allowed, it worked when
I had the files on an NT workstation) they get an error saying it is not
a quickbooks file, and the smbstatus follows:
Locked files:
Pid DenyMode R/W Oplock Name

Another smbstatus later in time:

So we have no oplocks and everything is read write.
Any help would be great.
Thanks

hello, how is it possible to unlock a file, which is locked by a oplock, without restart the samba server? ( sorry my english ) i use: samba 2.2.7 linux regards marcel beltz
Dear List, I'm using samba 2.2.8a as a PDC which I built from the src.rpm on a RedHat 9 box. In every file share (including homes and netlogon) I have the following lines. kernel oplocks = no level2 oplocks = no In smbd.log I keep getting the following lines [2003/05/06 17:28:35, 0] smbd/oplock_linux.c:linux_init_kernel_oplocks(287) Failed to setup RT_SIGNAL_LEASE handler I have about 40 machines using Win98, Win2000 and WinXP. In the global section I had oplocks = no and that didn't seem to help so I commented it out. If I have oplocks turned off why do I still get the error messages in smbd.log? TIA Warren
I have read that I need to turn oplocks off for QuickBooks. I think I understand what Oplocks are. I also believe I understand why I need to turn them off. But in Windows, where is this option? Are Oplocks always on in windows? If this is the case, I reiterate why do I need to turn them off in Samba? **********CONFIDENTIALITY STATEMENT********** This e-mail (including attachments) is covered by the Electronic Communications Privacy Act, 18 U.S.C. 2510-2521, is confidential and may be legally privileged.

In Samba you can turn them off per share or file or globally in the smb.conf. In Windows you can only turn them off globally in the registry. Jeremy.
