I must live in a different universe... I can't get decent performance from
Microsoft Word unless oplocks are on (and the client can thus cache the
whole file).
an to be able to do that i had to turn oplocks off so more then one
person can have it open at one time. be interesting to know how to do
that without oplocks on.
What about level 2 oplocks? The oplock system allows for multiple readers
when someone is writing.
Note that in the original example, the Access Database is expected to be
written to ("read only = No"). If the share was set read-only (and I don't
doubt that you'd have to set the file to read-only too, to make sure MS
Windows got the hint), I expect you wouldn't need oplocks.
But I've been wrong before... the only way to tell is to try it out and
see.
Hi,
as I've said in my post, there are multiple users that access simultaneously
to this mdb, and the directory in wich is contained has 777 permission
because all should modify this file or, to be more precise, everyone should
modify the LDB file that is created/modify every time someone access to mdb.
All my clients XP are configured NOT to request oplocks.
Here you are the registry that I load in the clients:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanserver\parameters]
"EnableOplocks"=dword:00000000
"MinLinkThroughput"=dword:00000000
"MaxLinkDelay"=dword:0000003c
; "OplockBreakWait"=dword:00000080
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\lanmanworkstation\parameters]
"UseOpportunisticLocking"=dword:00000000
Thanks.
Alex
