OP LOCKS and caching 1

[stla]

Does anyone have any information / experience with this. I have a problem whereby XP Home clients accessing a Access database get different results.

Apparently setting OP locks to No prevents caching but slows things down a bit.

Best regards

Make sure you have a backup of your data first!!! I cannot stress this enough. Disabling oplocks can allow Windows clients to step all over your data.

Also, copy your smb.conf file to be safe.

1. Disable oplocks on the workstations.

2. In smb.conf, set the following global parameter.

Oplocks = No

You may have to restart samba to have it take effect.
Check your samba logs before and after, to see if there is any difference in the fighting over file(s).
