Note that true concurrence depends on how many processor cores exist on the host system. Wouldn't using FILE_WRITE_THROUGH on your database file work just as well, though, while still allowing caching?

This option prevents browsing, but I've seen some requests for \dirname\* that caused get_lanman2_dir_entry to find the matches for this (I would have expected 'dont descend' to stop this). for (int i = 0; i < NUM_THREADS; i++) { CloseHandle(gThread[i]); } return 0; } This sample is a Windows console application that executes multiple concurrent accesses to a file, all If you have received it in error, please notify the sender immediately and delete the original.

What I think goes wrong is that the database reads from the locking file and sees an old version of the file that indicates that a record is unlocked and then Visit the following links: Site Howto | Site FAQ | Sitemap | Register Now If you have any problems with the registration process or your account login, please contact us.

Anon says: April 16, 2013 at 8:23 am @Gabe The problem with the oplocks is that SMB and the oplocks don't guarantee consistency - of any sort.

You can quit and then run smbstatus again and it should work. - John T. -- John H Terpstra Email: jht at samba.org Previous message: [Samba] Failed to open byte range in fact looking in > /var/lock/samba i can only see: > -rw-r--r-- 1 root root 8192 Jul 23 16:43 connections.tdb > -rw------- 1 root root 696 Jul 23 16:43 messages.tdb > If we're just modifying a record, we can get a // shared lock. Locking part of a file gives the threads of the locking processes exclusive access to the specified byte range by using the specified file handle.

I traced this down to two places in the code: 1) The trans2 routine get_lanman2_dir_entry loops through the entire directory looking for possible matches. navigate here Is there a wiki somewhere with a list of rules like these (which Raymond once called "taxes"; see blogs.msdn.com/…/454487.aspx)? Apparently Microsoft is afraid that people will sue them because of what an anonymous coward on the internet said.

Specify exclusive access, and fail // immediately if the lock cannot be obtained. GBiz is too!

It's annoying to have to write retry loops around so many calls to open a file handle. If you do want to overwrite them, be my guest, I didn't test that . 1st donation after taking so much , BK happy View Public Profile View LQ Blog Anything is fair game.

Anonymous Coward says: April 16, 2013 at 6:42 am Brian, I didn't know that.

The LockFile and LockFileEx functions lock a specified range of bytes in a file. If the locking process attempts to access a locked byte range through a second file handle, the attempt fails.
