<samba:parameter name="veto oplock files"
context="S"
type="string"
substitution="1"

<description>
<para>
This parameter is only valid when the <smbconfoption name="oplocks"/>
parameter is turned on for a share. It allows the Samba administrator
to selectively turn off the granting of oplocks on selected files that
match a wildcarded list, similar to the wildcarded list used in the
<smbconfoption name="veto files"/> parameter.
</para>
<para>
You might want to do this on files that you know will be heavily contended
for by clients. A good example of this is in the NetBench SMB benchmark
program, which causes heavy client contention for files ending in
<filename moreinfo="none">.SEM</filename>. To cause Samba not to grant
oplocks on these files you would use the line (either in the [global]
section or in the section for the particular NetBench share.
</para>
<para>
An example of use is:
<programlisting>
veto oplock files = /.*SEM/
</programlisting>
</para>
</description>
<value type="default"><comment>No files are vetoed for oplock grants</comment></value>
</samba:parameter>
